  18
  19 2.5.4
  20 -----
  21
  22 All:
  23
  24 - wxEvent and derived classes don't have public members any more, you must
  25   use accessors methods now (Mart Raudsepp)
  26 - new classes for reading and writing ZIP files (M.J.Wetherell)
  27 - large files support for wxFFile (M.J.Wetherell)
  28 - classes in the manual are now cross-referenced (Zbigniew Zagórski)
  29 - Norwegian (Bokmål) translation added (Hans F. Nordhaug)
  30 - wxDynamicLibrary::HasSymbol() added
  31 - added wxEXEC_NODISABLE flag to be used with wxExecute(wxEXEC_SYNC)
  32 - added wxTextInputStream::operator>>(wchar_t) for compilers which support this
  33 - added wxURI, a class for dealing with Uniform Resource Identifiers
  34 - changed wxURL to inherit from wxURI and provide assignment and comparison
  35 - implemented wxConvUTF7 (modified patch from Fredrik Roubert)
  36 - added versions of MB2WC and WC2MB for wxMBConv that for embedded null chars
  37 - Unicode support in wxODBC is now fully implemented
  38 - A new data type specific to wxWidgets called SQL_C_WXCHAR has been introduced.
  39   SQL_C_WXCHAR should be used rather than SQL_C_CHAR to ensure transparent
  40   behavior between Unicode and non-unicode builds
  41 - BLOB example added to samples/db (thanks to Casey ODonnell)
  42 - use wxStream::GetLength() instead of deprecated GetSize()
  43 - wxGetOsDescription() is now more precise (Olly Betts)
  44 - XRC supports system fonts and colours (Ray Gilbert)
  45 - Added flags argument to wxKill/wxProcess::Kill to kill child processes.
  46 - Added wxPrintFactory classes so that it is possible to add a new
  47   print system backend at run-time. This was required by the new GNOME
  48   printing stuff in the GTK port.
  49 - Deprecated print setup dialog.
  50 - Added support to the wxODBC classes for Firebird 1.5 database
  51 - The samples\db sample program now includes an optional example of using a BLOB
  52   datatype (if BLOB support is enabled and supported by the database)
  53 - added wxDynamicLibrary::ListLoaded()
  54 - wxGetPowerType() and wxGetBatteryState() addition
  55 - wxSystemSettings::GetSystem*() members deprecated and replaced with
  56   wxSystemSettings::Get*()
  57 - wxWindowBase::DoGetBestSize now includes the difference (if any) between
  58   the client size and total size of the window.  Code that sets the
  59   client size using the best size, or that added extra space to sizers
  60   to compensate for this bug may need to be changed.
  61 - Changed calculation of scrolling area to not clip away some bits
  62   due to a rounding error.
  63 - Changed GetVirtualSize() to return client size by default until
  64   SetVirtualSize() gets called. From then on it will only return that.
  65 - Various changes to how wxListCtrl and wxTreeCtrl react to right
  66   mouse clicks and left mouse click for starting a drag operation.
  67 - "Alt" key (VK_MENU) now results in WXK_ALT keyboard event, not WXK_MENU
  68 - wxFFile::ReadAll() now takes an optional wxMBConv parameter

  77 - wxHtmlWindow now supports background images given in <body> tag
  78 - wxSplitterWindow now supports gravity parameter (Zbigniew Zagórski)
  79 - recursive wxSizer::GetItem returns item of given window, sizer or nth index
  80 - wxLayoutConstraints now use best size, not current size, for AsIs() condition
  81 - wxSizer::Add/Insert etc. now returns pointer to wxSizerItem just added and this
  82   item remembers its wxRect area (Brian A. Vanderburg II)
  83 - wxBookCtrl renamed to wxBookCtrlBase, wxBookCtrl is reserved for most native
  84   book control (for now wxChoicebook for MSSmartphone, wxNotebook for others).
  85   Necessary event macros, types and styles mapped accordingly.
  86 - new wxBrush::IsHatch() checking for brush type replaces IS_HATCH macro
  87 - wxProgressDialog accepts smooth gauge again (wxPD_SMOOTH style)
  88 - wxProgressDialog new style: wxPD_CAN_SKIP which provides skipping some parts
  89   of the progress (with new "Skip" button in dialog)
  90 - wxGenericListCtrl::SetItemState(-1) now changes the state of all items as
  91   in wxMSW version (Gunnar Roth)
  92 - added wxImage::InitAlpha()

  94 Unix:
  95
  96 - wxPuts() now correctly outputs trailing new line in Unicode build
  97
  98 wxGTK:
  99
 100 - Added printing support by way of using libgnomeprint. The library
 101   now checks at runtime, if the library is installed and will use it
 102   if it is. Otherwise, it will fall back to the old PostScript printing
 103   code, from which the Pango drawing code was removed.
 104 - Implemented/improved wxDC::DrawRotatedText()
 105 - fixed wxFileDialog::SetWildcard()
 106 - native file dialog is now used if available (Zbigniew Zagorski)
 107 - implemented wxTextCtrl::Freeze() and Thaw(). The GtkTextBuffer
 108   is not a valid one during frozen state. Get a pointer to it right
 109   after wxTextCtrl creation if you really need to. (Mart Raudsepp)
 110 - Changed calls to GTK+ 2.4.x functions so that the code checks at
 111   runtime, which library version is installed so that these functions
 112   are only called with GTK+ 2.4.x installed and should yield linker
 113   errors otherwise.
 114 - wxTextCtrl text insertion efficiency fixed. (Mart Raudsepp)
 115 - Added wxRawBitmap support
 116 - Corrected Input method handler code (for Chinese etc.) and its
 117   interaction with wxWidgets' events.
 118 - wxTE_AUTO_URL implemention for wxGTK2 multiline wxTextCtrls (Mart Raudsepp)
 119
 120 wxMac:

 137   but not mentioned anywhere.
 138 - Added (preliminary) support for sockets
 139
 140 wxUniv:

 147 wxPalmOS:
 148
 149 - William Osborne has won and new port was born
 150   (see: "wxPalmOS porting challenge")
 151 - polishing of the port (unnecessary 2.4 API compatibility, removed
 152   all wxMSW specific code which was base for the new port)

 302
 303 2.5.2
 304 -----
 305
 306 All:
 307
 308 - Hindi translation added (Dhananjaya Sharma)
 309 - Brazilian Portuguese translation added (E. A. Tacao)
 310 - wxDynamicCast() now uses static_cast<wxObject *> internally and so using it
 311   with anything not deriving from wxObject will fail at compile time (instead
 312   of run-time) now
 313 - when wxUSE_STL == 1 and STL provides quasi-standard hash_map/hash_set,
 314   wxHashMap/wxHashSet are just typedefs for them. This makes impossible
 315   to forward declare these classes.
 316
 317 All (GUI):
 318
 319 - wxHtmlWindow now delays image scaling until rendering,
 320   resulting in much better display of scaled images
 321 - Added UpdateSize to wxSplitterWindow to allow layout while hidden
 322 - implemented Freeze/Thaw() for wxGenericTreeCtrl (Kevin Hock)
 323 - support for KOI8-U encoding added (Yuriy Tkachenko)
 324 - The old wxADJUST_MINSIZE behaviour is now the default behaviour for
 325   sizer items that are windows.  This means that GetAdjustedBestSize
 326   will now be called by default to determine the minimum size that a
 327   window in a sizer should have.  If you want to still use the initial
 328   size (and not the BestSize) then use the wxFIXED_MINSIZE flag.  When
 329   windows are added to a sizer their initial size is made the window's
 330   min size using SetSizeHints, and calls to wxSizer::SetItemMinSize
 331   are also forwarded to SetSizeHints for window items.
 332 - added wxRegEx::GetMatchCount()
 333 - it is now possible to display images in wxHtmlListBox
 334
 335 wxMSW:
 336
 337 - wxWindow::Freeze()/Thaw() can now be nested
 338 - Added wxSP_NO_XP_THEME style to wxSplitterWindow to switch off
 339   XP theming (some applications look bad without 3D borders)
 340 - wxMenuBar::GetLabelTop() doesn't include '&'s in the label any more
 341 - wxRegConf couldn't read global settings without admin privileges and didn't
 342   even try to do it by default -- now it does
 343 - wxTaskBarIcon must be explicitly destroyed now, otherwise the application
 344   won't exit even though there are no top level windows
 345 - wxFileName::GetModificationTime() works with opened files too now
 346 - wxDC::GetClippingBox() now works even for clipping regions created by Windows
 347 - fixed wxFileDataObject in Unicode build (Alex D)
 348 - subindented paragraphs support (Tim Kosse)
 349
 350 wxGTK:
 351
 352 - added support for wxTE_RIGHT and wxTE_CENTRE styles under GTK2 (Mart Raudsepp)
 353
 354 wxMotif:
 355
 356 - removed wxMenuItem::DeleteSubMenu()
 357 - wxButtons use Motif default size, which is smaller than it used to be
 358   and closer to wxMSW/wxGTK look. This can be disabled by setting
 359   motif.largebuttons system option to 1 (see wxSystemOptions).
 360
 361 wxUniv/X11:
 362
 363 - implemented DrawRoundedRectangle() (clawghoul)
 364
 365 wxHTML:
 366
 367 - improved tables and lists layout algorithms (Tim Kosse)
 368 - <div> handling fix (Xavier Nodet)
 369
 370 Unix:
 371
 372 - fixed priorities of mailcap entries (David Hart)
 373 - added "wx-config --libs=std,<extra>" syntax (i.e. support for "std")
 374
 375 wxODBC:
 376
 377 - Full Unicode support is now available
 378 - BLOB support is working
 379
 380

 511 -----
 512
 513 All:
 514

 541   std::vector, wxList from std::list. In addition wxHashTable will be
 542   implemented in terms of wxHashMap.
 543 - Added wxList::compatibility_iterator. Can be used like wxNode* (except
 544   it can't be delete()d). It permits writing code which will work
 545   both with wxUSE_STL==1 and wxUSE_STL==0.
 546
 547 wxBase:
 548

 575 - FL: removed const from EnableTool parameters
 576 - FL: signal child window when toolbar is closed
 577 - In various places, changed tests for pathsep on last char of string to call
 578   wxEndsWithPathSeparator(s)

 592   to allow better rich text support.
 593 - implemented wxFlexGridSizer::Show() (Wade Brainerd)
 594 - Added m_ prefix to wxColourData and wxFontData members
 595 - Added wxHtmlPrintout::AddFilter so HTML printing can be subject to
 596   custom filters as well as HTML viewing.
 597 - Moved wxApp::SendIdleEvents and wxApp::ProcessIdle into common code.
 598 - wxWindow::OnInternalIdle is now used in all ports, and ensures that
 599   user OnIdle events do not interfere with crucial internal processing.
 600 - wxWindow::UpdateWindowUI is now a documented function that
 601   sends wxUpdateUIEvents, and can be overridden. It has a helper function
 602   DoUpdateWindowUI for taking appropriate wxUpdateUIEvent action.
 603 - Added functions to wxUpdateUIEvent: Set/GetMode, Set/GetUpdateInterval,
 604   CanUpdate, to assist with optimising update event frequency.
 605 - Added functions to wxIdleEvent: Set/GetMode, CanSend, to
 606   determine whether a window should receive idle events.
 607 - Added wxWS_EX_PROCESS_IDLE, wxWS_EX_PROCESS_UI_UPDATES window
 608   styles for use with conservative idle and update event modes.
 609 - send menu update events only when a menu is about to be used (MSW/GTK)
 610 - improved event processing performance (Hans Van Leemputten)
 611 - added wxMirrorDC class
 612 - printing improvements: GetPageInfo() gets called after the DC has
 613   been set and after OnPreparePrinting() has been called so it can
 614   report the number of pages accurately; doesn't try to set
 615   number of pages in print dialog, in common with other Windows apps;
 616   wxHTML easy printing's preview shows number of pages
 617   correctly; preview scrollbars are set correctly; keyboard navigation
 618   improved
 619

 673 - Windows XP manifest is now included in wx.rc; it is no longer necessary
 674   to ship .exe.manifest file with applications to support XP themes
 675 - wxLocale::Init no longer reports error if trying to set Unicode-only locale
 676   or if user's default locale is Unicode-only
 677 - improved border handling under Windows XP
 678 - partial fix for wxNotebook pages looking bad under XP: wxUSE_UXTHEME
 679   enables XP theme engine code, and wxUSE_UXTHEME_AUTO tells
 680   wxWidgets to use the theme tab colour for control backgrounds.
 681 - disable wxNB_RIGHT, wxNB_LEFT, wxNB_BOTTOM notebook styles under Windows XP
 682 - fixed release mode build with VC 7.x (Martin Ecker)

 690   documentation for a detailed explanation
 691 - implemented wxWakeUpIdle
 692 - for Motif 2.0, used the native combobox widget instead of the GPL'd

 714 OLD CHANGES
 715 ===========
 716
 717 INCOMPATIBLE CHANGES SINCE 2.2.x
 718 ================================
 719
 720     Please take a few minutes to read the following list, especially
 721     paying attention to the most important changes which are marked
 722     with '!' in the first column.
 723
 724     Also please note that you should ensure that WXWIN_COMPATIBILITY_2_2
 725     is defined to 1 if you wish to retain maximal compatibility with 2.2
 726     series -- however you are also strongly encouraged to try to compile
 727     your code without this define as it won't be default any longer in
 728     2.6 release.
 729
 730     NB: if you want to build your program with different major versions
 731         of wxWidgets you will probably find the wxCHECK_VERSION() macro
 732         (see the documentation) useful.
 733
 734
 735 wxBase:
 736
 737 ! wxArray<T>::Remove(size_t) has been removed to fix compilation problems
 738   under 64 bit architectures, please replace it with RemoveAt() in your
 739   code.
 740
 741 ! wxArray<T> macros have been changed to fix runtime problems under 64 bit
 742   architectures and as a side effect of this WX_DEFINE_ARRAY() can only be
 743   used now for the pointer types, WX_DEFINE_ARRAY_INT should be used for the
 744   arrays containing non-pointers.
 745
 746 - wxObject::CopyObject() and Clone() methods were removed because they
 747   simply don't make sense for all objects
 748
 749 - wxEvent now has a pure virtual Clone() method which must be implemented
 750   by all derived classes, if you have user-defined event classes please
 751   add "wxEvent *Clone() const { return new MyEvent(*this); }" line to them
 752
 753 - small change to wxStopWatch::Pause() semantics, please see the documentation
 754
 755 - unlikely but possible incompatibility: the definition of TRUE has changed
 756   from "1" to "(bool)1" (and the same thing for FALSE), so the code which
 757   could be erroneously compiled previously such as doing "return FALSE" from
 758   a function returning a pointer would stop compiling now (but this change
 759   is not supposed to have any effects on valid code)
 760
 761 - another minor change: wxApp::OnAssert() has a new "cond" argument, you
 762   must modify YourApp::OnAssert() signature if you were using it to override
 763   the default assert handling.
 764
 765 All (GUI):
 766
 767 ! the event type constants are not constants any more but are dynamically
 768   allocated during run-time which means that they can't be used as case labels
 769   in the switch()es, you must rewrite them to use if()s instead
 770
 771   You may also define WXWIN_COMPATIBILITY_EVENT_TYPES to get the old behaviour
 772   but this is strongly discouraged, please consider changing your code
 773   instead!
 774
 775 ! wxDialog does not derive from wxPanel any longer - if you were using it in
 776   your code, please update it. The quick fix for the most cases is to replace
 777   the occurrences of wxPanel with wxWindow.
 778
 779 ! if you handle (and don't skip) EVT_KEY_DOWN, the EVT_CHAR event is not
 780   generated at all, so you must call event.Skip() in your OnKeyDown() if
 781   you want to get OnChar() as well
 782
 783 - in general, the key events sent for the various non ASCII key combinations
 784   have been changed to make them consistent over all supported platforms,
 785   please see the wxKeyEvent documentation for details
 786
 787 - wxYES_NO is now wxYES | wxNO and the manifest values of both wxYES and wxNO
 788   have changed (to fix some unfortunate clashes), please check your code to
 789   ensure that no tests for wxYES or wxNO are broken: for example, the following
 790   will *NOT* work any longer:
 791
 792         if ( flags & wxYES_NO )
 793                 ... do something ...
 794         if ( flags & wxYES )
 795                 ... do something else ...
 796
 797 - static wxWizard::Create() doesn't exist any more, the wizards are created
 798   in the same way as all the other wxWindow objects, i.e. by directly using
 799   the ctor
 800
 801 - wxGLCanvas now derives directly from wxWindow, not wxScrolledWindow
 802
 803 - wxGridCellAttrProvider class API changed, you will need to update your code
 804   if you derived any classes from it
 805
 806 - wxImage::ComputeHistogram()'s signature changed to
 807   unsigned long ComputeHistogram(wxImageHistogram&) const
 808
 809 - wxEvtHandler cannot be copied/assigned any longer - this never worked but
 810   now it results in compile-time error instead of run-time crashes
 811
 812 - WXK_NUMLOCK and WXK_SCROLL keys no longer result in EVT_CHAR() events,
 813   they only generate EVT_KEY_DOWN/UP() ones
 814
 815 - the dialogs use wxApp::GetTopWindow() as the parent implicitly if the
 816   parent specified is NULL, use wxDIALOG_NO_PARENT style to prevent this
 817   from happening
 818
 819 - several obsolete synonyms are only retained in WXWIN_COMPATIBILITY_2_2 mode:
 820   for example, use wxScrolledWindow::GetViewStart() now instead of ViewStart()
 821   and GetCount() instead of Number() in many classes
 822
 823 - wxCmdLineParser does not use wxLog to output messages anymore.
 824   to obtain the previous behaviour, add
 825   wxMessageOutput::Set(new wxMessageOutputLog); to your program
 826   (you will need to #include <wx/msgout.h>)
 827
 828 wxMSW:
 829
 830 ! build system changed: setup.h is not a static file in include/wx any more
 831   but is created as part of the build process under lib/<toolkit>/wx
 832   where <toolkit> is of the form (msw|univ)[dll][u][d]. You'll need to update
 833   the include path in your make/project files appropriately. Furthermore,
 834   xpm.lib is no longer used by wxMSW, it was superseded by the wxXPMDecoder
 835   class. You'll need to remove all references to xpm.lib from your
 836   make/project files. Finally, the library names have changed as well and now
 837   use the following consistent naming convention: wxmsw[ver][u][d].(lib|dll)
 838   where 'u' appears for Unicode version, 'd' -- for the debug one and version
 839   is only present for the DLLs builds.
 840
 841 - child frames appear in the taskbar by default now, use wxFRAME_NO_TASKBAR
 842   style to avoid it
 843
 844 - all overloads of wxDC::SetClippingRegion() combine the given region with the
 845   previously selected one instead of replacing it
 846
 847 - wxGetHomeDir() uses HOME environment variable and if it is set will not
 848   return the programs directory any longer but its value (this function has
 849   never been meant to return the programs directory anyhow)
 850
 851 - wxHTML apps don't need to include wx/html/msw/wxhtml.rc in resources file
 852   anymore. The file was removed from wxMSW
 853
 854
 855 Unix ports:
 856
 857 ! You should use `wx-config --cxxflags` in your makefiles instead of
 858   `wx-config --cflags` for compiling C++ files. CXXFLAGS contains CFLAGS
 859   and the compiler flags for C++ files only, CFLAGS should still be used
 860   to compile pure C files.
 861
 862
 863 wxThread and related classes:
 864
 865 - The thread-related classes have been heavily changed since 2.2.x versions
 866   as the old code had many serious problems. This could have resulted in
 867   semantical changes other than those mentioned here, please review use of
 868   wxThread, wxMutex and wxCondition classes in your code.
 869
 870 ! wxCondition now *must* be used with a mutex, please read the (updated) class
 871   documentation for details and revise your code accordingly: this change was
 872   unfortunately needed as it was impossible to ensure the correct behaviour
 873   (i.e. absence of race conditions) using the old API.
 874
 875 - wxMutex is not recursive any more in POSIX implementation (it hasn't been
 876   recursive in 2.2.x but was in 2.3.1 and 2.3.2), please refer to the class
 877   documentation for the discussion of the recursive mutexes.
 878
 879 - wxMutex::IsLocked() doesn't exist any more and should have never existed:
 880   this is was unique example of a thread-unsafe-by-design method.
 881

1516 - Added wxUSE_SOCKETS.
1517 - More topic overviews.
1518 - Put wxPrintPaperType, wxPrintPaperDatabase into
1519   prntbase.h/cpp for use in non-PostScript situations
1520   (e.g. Win16 wxPageSetupDialog).
1521
1522

1525
1526 wxGTK:
1527
1528 - wxExecute improved.
1529
1530 wxMSW:
1531
1532 - Fixed wxWindow::IsShown (::IsWindowVisible doesn't behave as
1533   expected).
1534 - Changed VC++ makefiles (.vc) so that it's possible to have
1535   debug/release/DLL versions of the library available simultaneously,
1536   with names wx.lib, wx_d.lib, wx200.lib(dll), wx200_d.lib(dll).
1537 - Added BC++ 5 IDE files and instructions.
1538 - Fixed wxChoice, wxComboBox constructor bugs (m_noStrings initialisation).
1539 - Fixed focus-related crash.
1540
1541 wxMotif:
1542
1543 - Cured asynchronous wxExecute crash.
1544 - Added repaint event handlers to wxFrame, wxMDIChildFrame.
1545
1546 General:
1547
1548 - wxLocale documented.
1549 - Added include filenames to class reference.
1550 - wxHelpController API changed: SetBrowser becomes SetViewer,
1551   DisplaySection works for WinHelp, help sample compiles under Windows
1552   (though doesn't display help yet).
1553
1554 Beta 4, February 12th 1999
1555 --------------------------
1556
1557 wxGTK:
1558
1559 - Miscellaneous fixes.
1560
1561 wxMSW:
1562
1563 - Makefiles for more compilers and samples; Cygwin makefiles
1564   rationalised.
1565 - Added VC++ project file for compiling wxWidgets as DLL.
1566
1567 wxMotif:
1568
1569 - Added OnEraseBackground invocation.
1570 - Added wxRETAINED implementation for wxScrolledWindow.
1571 - Cured scrolling display problem by adding XmUpdateDisplay.
1572 - Tried to make lex-ing in the makefile more generic (command line
1573   syntax should apply to both lex and flex).
1574 - Changed file selector colours for consistency (except for buttons:
1575   crashes for some reason).
1576 - Fixed wxMotif version of wxImage::ConvertToBitmap (used new instead
1577   of malloc, which causes memory problems).
1578
1579 General:
1580
1581 - Further doc improvements.
1582 - wxGenericValidator added.
1583 - Added wxImageModule to image.cpp, so adds/cleans up standard handlers
1584   automatically.
1585
1586 Beta 3, January 31st 1999
1587 -------------------------
1588
1589 wxGTK:
1590

1592 - wxToolTip class added.
1593 - Miscellaneous fixes.
1594
1595 wxMSW:
1596
1597 - wxRegConfig DeleteAll bug fixed.
1598 - Makefiles for more compilers.
1599 - TWIN32 support added.
1600 - Renamed VC++ makefiles from .nt to .vc, and

1619 --------------------
1620
1621 wxGTK:
1622
1623 wxMSW:
1624
1625 - 16-bit BC++ compilation/linking works albeit without the resource system.
1626
1627 wxMotif:
1628
1629 - Cured wxScreenDC origin problem so e.g. sash window sash is drawn at
1630   the right place.
1631 - Cured some widget table clashes.
1632 - Added thread support (Robert).
1633 - wxPoem sample now works.
1634
1635 General:
1636
1637 - Rearranged documentation a bit.
1638 - Sash window uses area of first frame/dialog to paint over when drawing
1639   the dragged sash, not just the sash window itself (it clipped to the right
1640   or below).
1641 - Made resource sample use the correct Cancel button id.
1642 - Moved wxProp to main library (generic directory), created proplist
1643   sample.
1644 - Added bombs and fractal samples.
1645
1646 Beta 1, December 24th 1998
1647 --------------------------
1648
1649 wxGTK:
1650
1651 - Various
1652
1653 wxMSW, wxMotif: not in sync with this release.
1654
1655
1656 Alpha 18, December 29th 1998
1657 ----------------------------
1658
1659 wxMSW:
1660
1661 - Win16 support working again (VC++ 1.5)
1662 - Win16 now uses generic wxNotebook, wxListCtrl,
1663   wxTreeCtrl -- more or less working now, although
1664   a little work on wxNotebook is still needed.
1665   Under 16-bit Windows, get assertion when you click
1666   on a tab.
1667 - Wrote 16-bit BC++ makefiles: samples don't yet link.
1668 - Added CodeWarrior support to distribution courtesy
1669   of Stefan Csomor.
1670
1671 wxMotif:
1672
1673 - Cured scrolling problem: scrollbars now show/hide themselves
1674   without (permanently) resizing the window.
1675 - Removed some commented-out lines in wxScrolledWindow::AdjustScrollbars
1676   that disabled scrollbar paging.
1677 - Set background colour of drawing area in wxWindow, so e.g. wxListCtrl
1678   colours correctly.
1679 - Removed major bug whereby dialogs were unmanaged automatically
1680   when any button was pressed.
1681 - Fixed colours of wxWindow scrollbars, made list and text controls
1682   have a white background.
1683 - Fixed dialog colour setting.
1684 - Added settable fonts and colours for wxMenu/wxMenuBar. Now
1685   they have sensible colours by default.
1686 - Fixed a bug in wxStaticBox.
1687 - Cured wxTreeCtrl bug: now works pretty well!
1688 - Debugged DrawEllipticArc (a ! in the wrong place).
1689 - Added SetClippingRegion( const wxRegion& region ).
1690 - Added wxPoint, wxSize, wxRect versions of SetSize etc.
1691
1692 Alpha 17, November 22nd 1998
1693 ----------------------------
1694
1695 wxMSW:
1696
1697 - More documentation updates, especially for
1698   wxLayoutWindow classes and debugging facilities.
1699 - Changed wxDebugContext to use wxDebugLog instead
1700   of wxTrace.
1701 - Now supports VC++ 6.0, and hopefully BC++ 5.0.
1702   However, DLL support may be broken for BC++ since
1703   VC++ 6 required changing of WXDLLEXPORT keyword
1704   position.
1705 - Numerous miscellaneous changes.
1706
1707 wxMotif:
1708
1709 - Reimplemented MDI using wxNotebook instead of the MDI widgets, which
1710   were too buggy (probably not design for dynamic addition/removal of
1711   child frames).
1712 - Some improvements to the wxNotebook implementation.
1713 - wxToolBar now uses a bulletin board instead of a form, in an attempt
1714   to make it possible to add ordinary wxControls to a toolbar.
1715 - Cured problem with not being able to use global memory operators,
1716   by defining two more global operators, so that the delete will match
1717   the debugging implementation.
1718 - Added wxUSE_DEBUG_NEW_ALWAYS so we can distinguish between using
1719   global memory operators (usually OK) and #defining new to be
1720   WXDEBUG_NEW (sometimes it might not be OK).
1721 - Added time.cpp to makefile; set wxUSE_DATETIME to 1.
1722 - Added a parent-existence check to popup menu code to make it not crash.
1723 - Added some optimization in wxWindow::SetSize to produce less flicker.
1724   It remains to be seen whether this produces any resize bugs.
1725
1726 It's a long time since I updated this file. Previously done:
1727
1728 - wxFrame, wxDialog done.
1729 - wxScrolledWindow done (but backing pixmap not used at present).
1730 - wxBitmap done though could be tidied it up at some point.
1731 - Most basic controls are there, if not rigorously tested.
1732 - Some MDI support (menus appear on child frames at present).
1733 - wxNotebook almost done.
1734 - wxToolBar done (horizontal only, which would be easy to extend
1735   to vertical toolbars).
1736
1737 More recently:
1738
1739 - Colour and font changing done (question mark over what happens
1740   to scrollbars).
1741 - Accelerators done (for menu items and buttons). Also event loop
1742   tidied up in wxApp so that events are filtered through ProcessXEvent.
1743 - wxWindow::GetUpdateRegion should now work.
1744
1745 Alpha 16, September 8th 1998
1746 ----------------------------
1747
1748 wxMSW:
1749
1750 - Added wxSashWindow, wxSashLayoutWindow classes, and sashtest
1751   sample.
1752 - Guilhem's socket classes added, plus wxsocket sample.
1753 - A few more makefiles added.
1754 - GnuWin32/BC++ compatibility mods.
1755 - Further doc updates.
1756 - wxProp updates for correct working with wxGTK.
1757
1758 wxMotif:
1759
1760 - First start at Motif port.
1761 - Made makefiles for wxMotif source directory and minimal sample.
1762 - First go at wxApp, wxWindow, wxDialog, wxPen, wxBrush, wxFont,
1763   wxColour, wxButton, wxCheckBox, wxTextCtrl, wxStaticText,
1764   wxMenu, wxMenuItem, wxMenuBar
1765
1766 Alpha 15, August 31st 1998
1767 --------------------------
1768
1769 wxMSW:
1770
1771 - wxBitmap debugged.
1772 - wxDC::GetDepth added.
1773 - Contribution added whereby wxBitmap will be
1774   converted to DC depth if they don't match.
1775 - wxConfig API improved, documentation updated.
1776 - Printing classes name conventions cleaned up.
1777 - wxUpdateUIEvent now derives from wxCommandEvent
1778   so event can travel up the window hierarchy.
1779
1780 Alpha 14, July 31st 1998
1781 ------------------------
1782
1783 wxMSW:
1784
1785 - Toolbar API has been simplified, and now
1786   wxFrame::GetClientArea returns the available client
1787   area when toolbar, status bar etc. have been accounted for.
1788   wxFrame::CreateToolBar added in line with CreateStatusBar.
1789 - Documentation updates, incl. for wxToolBar.
1790 - New wxAcceleratorTable class plus wxFrame::SetAcceleratorTable.
1791 - Various additions from other folk, e.g. streams, wxConfig
1792   changes, wxNotebook.
1793 - Added wxDocMDIParentFrame, wxDocMDIChildFrame for doc/view.
1794
1795 Alpha 13, July 8th 1998
1796 -----------------------
1797
1798 wxMSW:
1799
1800 - Implemented wxPoint as identical to POINT on Windows, and
1801   altered wxDC wxPoint functions to use wxPoint directly in
1802   Windows functions, for efficiency.
1803 - Cured wxASSERT bug in wxStatusBar95.
1804 - #ifdefed out some bits in oleutils.cpp for compilers that
1805   don't support it.
1806 - Added some operators to wxPoint, wxSize.
1807 - Added inline wxDC functions using wxPoint, wxSize, wxRect.
1808
1809 Alpha 12, July 7th 1998
1810 -----------------------
1811
1812 wxMSW:
1813
1814 - Added wxApp::GetComCtl32Version, and wxTB_FLAT style, so can
1815   have flat toolbars on Win98 or Win95 with IE >= 3 installed.
1816
1817 Alpha 11, July 3rd 1998
1818 -----------------------
1819
1820 wxMSW:
1821
1822 - Added thread.h, thread.cpp.
1823 - Changed Enabled, Checked to IsEnabled, IsChecked in wxMenu,
1824   wxMenuBar.
1825 - Changed wxMenuItem::SetBackColor to SetBackgroundColour,
1826   SetTextColor to SetTextColour, and added or made public several
1827   wxMenuItem accessors.
1828 - Added two overloads to wxRegion::Contains. Added
1829   wxRegion::IsEmpty for a more consistent naming convention.
1830 - Added Vadim's wxDataObject and wxDropSource.
1831 - ENTER/LEAVE events now work.
1832 - Cured wxMemoryDC bug where the DC wasn't being deleted.
1833 - Cured wxGauge SetSize major bugginess.
1834 - Cured problem where if a GDI object was created on the stack,
1835   then went out of scope, then another object was selected into
1836   the DC, GDI objects would leak. This is because the assignment
1837   to e.g. wxDC::m_pen would delete the GDI object without it first
1838   being selected out of the DC. Cured by selecting the old DC object
1839   first, then doing the assignment.
1840 - Split up wxGaugeMSW, wxGauge95, wxSliderMSW, wxSlider95
1841 - Various other bug fixes and additions.
1842
1843 Generic:
1844
1845 - Major work on Dialog Editor (still plenty to go).
1846 - Expanded documentation a bit more.
1847
1848 Alpha 10, May 7th 1998
1849 ----------------------
1850
1851 wxMSW:
1852
1853 - Added desiredWidth, desiredHeight parameters to wxBitmapHandler
1854   and wxIcon functions so that you can specify what size of
1855   icon should be loaded. Probably will remain a Windows-specific thing.
1856 - wxStatusBar95 now works for MDI frames.
1857 - Toolbars in MDI frames now behave normally. They still
1858   require application-supplied positioning code though.
1859 - Changed installation instructions, makefiles and batch files
1860   for compiling with Gnu-Win32/Mingw32/EGCS. Also timercmn.cpp
1861   change to support Mingw32/EGCS. Bison now used by default.
1862
1863 Alpha 9, April 27th 1998
1864 ------------------------
1865
1866 wxMSW:
1867
1868 - Cured bug in wxStatusBar95 that caused a crash if multiple
1869   fields were used.
1870 - Added Gnu-Win32 b19/Mingw32 support by changing resource
1871   compilation and pragmas.
1872 - Cured wxMenu bug introduced in alpha 8 - didn't respond to
1873   commands because VZ changed the id setting in wxMenu::MSWCommand.
1874
1875 Generic:
1876
1877 - Corrected some bugs, such as the wxModule compilation problem.
1878 - Added Gnu-Win32 b19/Mingw32 support by changing resource
1879   compilation and pragmas.
1880 - Changed SIZEOF to WXSIZEOF.
1881
1882 Alpha 8, April 17th 1998
1883 ------------------------
1884
1885 wxMSW:
1886
1887 - Added IsNull to wxGDIObject to check if the ref data is present or not.
1888 - Added PNG handler and sample - doesn't work for 16-bit PNGs for
1889   some reason :-(
1890 - Added wxJoystick class and event handling, and simple demo.
1891 - Added simple wxWave class. Needs Stop() function.
1892 - Added wxModule (module.h/module.cpp) to allow definition
1893   of modules to be initialized and cleaned up on wxWidgets
1894   startup/exit.
1895 - Start of Mingw32 compatibility (see minimal and dialogs samples
1896   makefile.m95 files, and install.txt).
1897 - Note: Windows printing has stopped working... will investigate.
1898 VADIM'S CHANGES:
1899 - Updated wxString: bug fixes, added wxArrayString, some
1900   compatibility functions.
1901 - Updated log.h/cpp, added wxApp::CreateLogTarget.
1902 - file.h: new wxTempFile class.
1903 - defs.h: added wxSB_SIZE_GRIP for wxStatusBar95
1904 - statbr95: wxStatusBar95 control.
1905 - registry.h/cpp: wxRegKey class for Win95 registry.
1906 - listbox.cpp: corrected some bugs with owner-drawn listboxes.
1907 - wxConfig and wxFileConfig classes.
1908
1909 Generic:
1910
1911 - Added src/other/png, src/other/zlib directories.
1912 - Added samples/png.
1913 - IMPORTANT: Changed 'no id' number from 0 to -1, in wxEVT_ macros.
1914   Porters, please check particularly your wxTreeCtrl and wxListCtrl
1915   header files.
1916 - Added modules.h/cpp, config.cpp, fileconf.cpp, textfile.cpp/h.
1917
1918 Alpha 7, March 30th 1998
1919 ------------------------
1920
1921 wxMSW:
1922
1923 - Added tab classes, tab sample.
1924 - Now can return FALSE from OnInit and windows will be
1925   cleaned up properly before exit.
1926 - Improved border handling so panels don't get borders
1927   automatically.
1928 - Debugged MDI activation from Window menu.
1929 - Changes to memory debug handling, including checking for
1930   memory leaks on application exit - but see issues.txt for
1931   unresolved issues.
1932 - Added wxTaskBarIcon (taskbar.cpp/h, plus samples/taskbar)
1933   to allow maintenance of an icon in the Windows 95 taskbar
1934   tray area.
1935 - Got MFC sample working (MFC and wxWidgets in the same
1936   application), partly by tweaking ntwxwin.mak settings.
1937 - Got DLL compilation working again (VC++).
1938 - Changed wxProp/Dialog Editor filenames.
1939
1940 Generic:
1941
1942 - Added tab classes, tab sample.
1943 - Revised memory.cpp, memory.h slightly; memory.h now #defines
1944   new to WXDEBUG_NEW in DEBUG mode. Windows implementation app.cpp
1945   now checks for leaks on exit. Added memcheck sample.
1946   See src/msw/issues.txt for more details.
1947 - resource.h, resource.cpp changed to make wxDefaultResourceTable
1948   a pointer. Now initialize resource system with
1949   wxInitializeResourceSystem and wxCleanUpResourceSystem, to
1950   allow better control of memory.
1951 - wxString now derives from wxObject, to enable memory leak
1952   checking.
1953 - Added some #include fixes in various files, plus changed
1954   float to long in wxToolBar files.
1955
1956 Alpha 6, March 10th 1998
1957 ------------------------
1958
1959 wxMSW:
1960
1961 - Found stack error bug - stopped unwanted OnIdle recursion.
1962 - Removed bug in wxTreeCtrl::InsertItem I added in alpha 5.
1963 - Changed exit behaviour in wxApp/wxFrame/wxDialog. Now will
1964   check if the number of top-level windows is zero before
1965   exiting. Also, wxApp::GetTopWindow will return either
1966   m_topWindow or the first member of wxTopLevelWindows, so you
1967   don't have to call wxApp::SetTopWindow.
1968 - Added dynarray.h/dynarray.cpp (from Vadim).
1969 - Added first cut at OLE drag and drop (from Vadim). dnd sample
1970   added. Drop target only at this stage. See src/msw/ole/*.cpp,
1971   wx/include/msw/ole/*.h. WIN32 only because of UUID usage.
1972   Doesn't work with GnuWin32 - no appropriate headers e.g. for
1973   IUnknown.
1974   Doesn't work with BC++ either - crashes on program startup.
1975 - Added Vadim's owner-draw modifications - will probably remain
1976   Windows-only. This enhances wxMenu, wxListBox. See ownerdrw sample.
1977 - Added wxLB_OWNERDRAW for owner-draw listboxes.
1978 - Vadim's wxCheckListBox derives from wxListBox. See checklst sample.
1979   Doesn't entirely work for WIN16.
1980 - Vadim has added wxMenuItem as a separate file menuitem.cpp. It
1981   can also be used as an argument to wxMenu::Append, not just for
1982   internal implementation.
1983 - Some #ifdefs done for MINGW32 compilation (just alter OPTIONS
1984   in makeg95.env, together with mingw32.bat). However, resource
1985   binding is not working yet so most apps with dialogs crash.
1986
1987 Generic:
1988
1989 - Added Vadim's dynarray.h, dynarray.cpp.
1990 - Added Vadim's menuitem.cpp.
1991 - Added Windows-specific wxCheckListBox,
1992   owner-draw wxListBox, and drag-and-drop
1993   (see docs/msw/changes.txt).
1994
1995 Alpha 5, 14th February 1998
1996 --------------------------
1997
1998 wxMSW:
1999
2000 - GENERIC AND MSW-SPECIFIC CODE NOW TREATED AS TWO SEPARATE
2001   DISTRIBUTIONS. This change log will therefore now refer to
2002   the Windows-specific code only. See docs/changes.txt for generic
2003   changes.
2004 - Removed Windows-specific reference counting system (GDI
2005   resources were cleaned up in idle time) - minimal
2006   advantages now we have a wxWin reference counting system.
2007 - Added missing WXDLLEXPORT keywords so DLL compilation works
2008   again.
2009 - Removed most warnings for GnuWin32 compilation.
2010 - Added wxRegion/wxRegionIterator, but haven't yet used it in
2011   e.g. wxDC.
2012
2013 Generic:
2014
2015 - GENERIC AND MSW-SPECIFIC CODE NOW TREATED AS TWO SEPARATE
2016   DISTRIBUTIONS. This change log will therefore now refer to
2017   the generic code only. See docs/msw/changes.txt for Windows-specific
2018   changes.
2019 - Readmes, change logs and installation files now go in
2020   platform-specific directories under docs, e.g. docs/msw,
2021   docs/gtk.
2022 - Added DECLARE_APP and IMPLEMENT_APP macros so wxApp object gets
2023   created dynamically, not as a global object.
2024 - Put wxColour into wx/msw/colour.h, src/msw/colour.cpp.
2025 - Changed names of some include/wx/generic headers to be
2026   consistent and to conform to gcc pragma conventions. Also
2027   changed choicesg.cpp to choicdgg.cpp.
2028 - Added gcc pragmas.
2029 - Added gtk inclusion in include/wx headers.
2030 - Added consistent file headings to source and headers.
2031 - Removed lang.cpp, lang.h and references to wxSTR_... variables;
2032   added a few references to wxTransString.
2033 - Added operator to wxTransString that converts automatically
2034   to wxString, so we can say e.g. wxMessageBox(wxTransString("Hello"), ...).
2035 - samples/internat now works (minimally).
2036 - Added wxMouseEvent::GetPosition and
2037   wxMouseEvent::GetLogicalPosition, both returning wxPoints.
2038 - Made wxSize and wxRect contain longs not ints.
2039 - Cured some memory leaks (thanks Vadim).
2040 - Tidied up OnIdle and introduced RequestMore/MoreRequested so
2041   will only keep processing OnIdle if it returns TRUE from
2042   MoreRequested.
2043
2044 Alpha 4, 31st January 1998
2045 --------------------------
2046
2047 All:
2048
2049 - Changed wxDC functions to take longs instead of floats. GetSize now takes
2050   integer pointers, plus a version that returns a wxSize.
2051 - const keyword added to various wxDC functions.
2052 - Under Windows, wxDC no longer has any knowledge of whether
2053   an associated window is scrolled or not. Instead, the device
2054   origin is set by wxScrolledWindow in wxScrolledWindow::PrepareDC.
2055 - wxScrolledWindow applications can optionally override the virtual OnDraw
2056   function instead of using the OnPaint event handler. The wxDC passed to
2057   OnDraw will be translated by PrepareDC to reflect scrolling.
2058   When drawing outside of OnDraw, must call PrepareDC explicitly.
2059 - wxToolBarBase/wxToolBarSimple similarly changed to allow for
2060   scrolling toolbars.
2061 - Integrated wxPostScriptDC patches for 1.xx by Chris Breeze,
2062   to help printing with multiple pages.
2063 - IPC classes given base classes (wxConnectionBase etc.) which
2064   define the API used by different implementations. DDE
2065   implementation updated to use these base classes.
2066 - wxHelpInstance now separated into wxHelpControllerBase (base
2067   for all implementations), wxWinHelpController (uses standard
2068   WinHelp), wxXLPHelpController (talks to wxHelp by DDE or
2069   TCP/IP). There will be others eventually, such as
2070   wxHTMLHelpController for Microsoft (and Netscape?) HTML Help.
2071 - Added Vadim Zeitlin's wxString class plus
2072   internationalization code (gettext simulation, wxLocale, etc.).
2073   New files from Vadim:
2074   include\wx\string.h
2075   include\wx\debug.h
2076   include\wx\file.h
2077   include\wx\log.h
2078   include\wx\intl.h
2079   src\common\string.cpp
2080   src\common\log.cpp
2081   src\common\intl.cpp
2082   src\common\file.cpp
2083   No longer use GNU wxString files.
2084 - Split off file-related functions into include\wx\filefn.h and
2085   src\common\filefn.cpp.
2086 - Borland C++ support (WIN32) for main library and
2087   samples, using makefile.b32 files.
2088 - Preparation done for allowing BC++ to compile wxWin as a DLL,
2089   including changes to defs.h.
2090 - wxIntPoint removed, wxPoint is now int, and wxRealPoint
2091   introduced.
2092 - Added wxShowEvent (generated when window is being shown or
2093   hidden).
2094 - Got minimal, docview, mdi samples working for 16-bit VC++ and
2095   cured 16-bit problem with wxTextCtrl (removed global memory
2096   trick).
2097 - Updated GnuWin32 makefiles, checked minimal, mdi, docview samples.
2098
2099 Alpha 3, September 1997
2100 -----------------------
2101
2102 All:
2103
2104 - wxListCtrl, wxTreeCtrl, wxImageList classes done.
2105 - Instigated new file hierarchy, split files and classes up more logically.
2106 - PrologIO and some other utils now put into core library.
2107 - Revamped print/preview classes, added wxPageSetupDialog.
2108 - Started documentation.
2109
2110 Alpha 2, 30th April 1997
2111 ------------------------
2112
2113 All:
2114
2115 - EVT_... macros now have at least one argument, for conformance
2116   with MetroWerks compiler.
2117 - Added ids to .wxr file format.
2118 - Got Dialog Editor compiled and running again but need
2119   to extend functionality to be in line with new controls.
2120   Added dialoged\test app to allow dynamic loading of .wxr files
2121   for testing purposes.
2122 - Rewrote wxBitmap to allow installable file type
2123   handlers.
2124 - Rewrote wxBitmapButton, wxStaticBitmap to not use Fafa.
2125 - Wrote most of wxTreeCtrl and sample (need wxImageList to implement it
2126   fully).
2127 - Added back wxRadioBox.
2128 - Tidied up wx_main.cpp, wxApp class, putting PenWin code in
2129   a separate file.
2130
2131 Alpha 1, 5th April 1997
2132 -----------------------
2133
2134 Generic:
2135
2136 At this point, the following has been achieved:
2137
2138 - A lot, but not all, of the code has been revamped for better
2139   naming conventions, protection of data members, and use of
2140   wxString instead of char *.
2141 - Obsolete functionality deleted (e.g. default wxPanel layout,
2142   old system event system) and code size reduced.
2143 - Class hierarchy changed (see design doc) - base classes such
2144   as wxbWindow now removed.
2145 - No longer includes windows.h in wxWin headers, by using stand-in
2146   Windows types where needed e.g. WXHWND.
2147 - PrologIO revised.
2148 - wxScrolledWindow, wxStatusBar and new MDI classes added.
2149   MDI is now achieved using separate classes, not window styles.
2150 - wxSystemSettings added, and made use of to reflect standard
2151   Windows settings.
2152 - SetButtonFont/SetLabelFont replaced by SetFont; font and colour
2153   settings mucho rationalised.
2154 - All windows are now subclassed with the same window proc to make
2155   event handling far more consistent. Old internal wxWnd and derived
2156   classes removed.
2157 - API for controls revised, in particular addition of
2158   wxValidator parameters and removal of labels for some controls.
2159 - 1 validator written: see examples/validate.
2160 - Event table system introduced (see most samples and
2161   wx_event.cpp/ProcessEvent, wx_event.h). wxEvtHandler
2162   made more flexible, with Push/PopEventHandler allowing a chain
2163   of event handlers.
2164 - wxRadioBox removed - will be added back soon.
2165 - Toolbar class hierarchy revised:
2166   wxToolBarBase
2167   wxToolBarSimple (= old wxToolBar)
2168   wxToolBar95 (= old wxButtonBar under Win95)
2169   wxToolBarMSW (= old wxButtonBar under WIN16/WIN32)
2170 - Constraint system debugged somewhat (sizers now work properly).
2171 - wxFileDialog, wxDirDialog added; other common dialogs now
2172   have class equivalents. Generic colour and font dialogs
2173   rewritten to not need obsolete panel layout.
2174 - .wxr resource system partially reinstated, though needs
2175   an integer ID for controls. Hopefully the resource system
2176   will be replaced by something better and more efficient
2177   in the future.
2178 - Device contexts no longer stored with window and accessed
2179   with GetDC - use wxClientDC, wxPaintDC, wxWindowDC stack
2180   variables instead.
2181 - wxSlider uses trackbar class under Win95, and wxSL_LABELS flag
2182   determines whether labels are shown. Other Win95-specific flags
2183   introduced, e.g. for showing ticks.
2184 - Styles introduced for dealing with 3D effects per window, for
2185   any window: all Win95 3D effects supported, plus transparent windows.
2186 - Major change to allow 3D effect support without CTL3D, under
2187   Win95.
2188 - Bitmap versions of button and checkbox separated out into new
2189   classes, but unimplemented as yet because I intend to remove
2190   the need for Fafa - it apparently causes GPFs in Win95 OSR 2.
2191 - utils/wxprop classes working (except maybe wxPropertyFormView)
2192   in preparation for use in Dialog Editor.
2193 - GNU-WIN32 compilation verified (a month or so ago).
