  16
  17
  18 2.5.4
  19 -----
  20
  21 All:
  22
  23 - wxEvent and derived classes don't have public members any more, you must
  24   use accessors methods now (Mart Raudsepp)
  25 - new classes for reading and writing ZIP files (M.J.Wetherell)
  26 - large files support for wxFFile (M.J.Wetherell)
  27 - classes in the manual are now cross-referenced (Zbigniew Zagórski)
  28 - Norwegian (Bokmål) translation added (Hans F. Nordhaug)
  29 - wxDynamicLibrary::HasSymbol() added
  30 - added wxEXEC_NODISABLE flag to be used with wxExecute(wxEXEC_SYNC)
  31 - added wxTextInputStream::operator>>(wchar_t) for compilers which support this
  32 - added wxURI, a class for dealing with Uniform Resource Identifiers
  33 - changed wxURL to inherit from wxURI and provide assignment and comparison
  34 - implemented wxConvUTF7 (modified patch from Fredrik Roubert)
  35 - added versions of MB2WC and WC2MB for wxMBConv that for embedded null chars
  36 - Unicode support in wxODBC is now fully implemented
  37 - A new data type specific to wxWidgets called SQL_C_WXCHAR has been introduced.
  38   SQL_C_WXCHAR should be used rather than SQL_C_CHAR to ensure transparent
  39   behavior between Unicode and non-unicode builds
  40 - BLOB example added to samples/db (thanks to Casey ODonnell)
  41 - use wxStream::GetLength() instead of deprecated GetSize()
  42 - wxGetOsDescription() is now more precise (Olly Betts)
  43 - XRC supports system fonts and colours (Ray Gilbert)
  44 - Added flags argument to wxKill/wxProcess::Kill to kill child processes.
  45 - Added wxPrintFactory classes so that it is possible to add a new
  46   print system backend at run-time. This was required by the new GNOME
  47   printing stuff in the GTK port.
  48 - Deprecated print setup dialog.
  49 - Added support to the wxODBC classes for Firebird 1.5 database
  50 - The samples\db sample program now includes an optional example of using a BLOB
  51   datatype (if BLOB support is enabled and supported by the database)
  52 - added wxDynamicLibrary::ListLoaded()
  53 - wxGetPowerType() and wxGetBatteryState() addition
  54 - wxSystemSettings::GetSystem*() members deprecated and replaced with
  55   wxSystemSettings::Get*()
  56 - wxWindowBase::DoGetBestSize now includes the difference (if any) between
  57   the client size and total size of the window.  Code that sets the
  58   client size using the best size, or that added extra space to sizers
  59   to compensate for this bug may need to be changed.
  60 - Changed calculation of scrolling area to not clip away some bits
  61   due to a rounding error.
  62 - Changed GetVirtualSize() to return client size by default until
  63   SetVirtualSize() gets called. From then on it will only return that.
  64 - Various changes to how wxListCtrl and wxTreeCtrl react to right
  65   mouse clicks and left mouse click for starting a drag operation.
  66 - "Alt" key (VK_MENU) now results in WXK_ALT keyboard event, not WXK_MENU
  67 - wxFFile::ReadAll() now takes an optional wxMBConv parameter
  68 - wxCommandProcessor::MarkAsSaved() and IsDirty() added (Angela Wrobel)

  76 - wxHtmlWindow now supports background images given in <body> tag
  77 - wxSplitterWindow now supports gravity parameter (Zbigniew Zagórski)
  78 - recursive wxSizer::GetItem returns item of given window, sizer or nth index
  79 - wxLayoutConstraints now use best size, not current size, for AsIs() condition
  80 - wxSizer::Add/Insert etc. now returns pointer to wxSizerItem just added and this
  81   item remembers its wxRect area (Brian A. Vanderburg II)
  82 - wxBookCtrl renamed to wxBookCtrlBase, wxBookCtrl is reserved for most native
  83   book control (for now wxChoicebook for MSSmartphone, wxNotebook for others).
  84   Necessary event macros, types and styles mapped accordingly.
  85 - new wxBrush::IsHatch() checking for brush type replaces IS_HATCH macro
  86 - wxProgressDialog accepts smooth gauge again (wxPD_SMOOTH style)
  87 - wxProgressDialog new style: wxPD_CAN_SKIP which provides skipping some parts
  88   of the progress (with new "Skip" button in dialog)
  89 - wxGenericListCtrl::SetItemState(-1) now changes the state of all items as
  90   in wxMSW version (Gunnar Roth)
  91 - added wxImage::InitAlpha()
  92
  93 Unix:
  94
  95 - wxPuts() now correctly outputs trailing new line in Unicode build
  96
  97 wxGTK:
  98
  99 - Added printing support by way of using libgnomeprint. The library
 100   now checks at runtime, if the library is installed and will use it
 101   if it is. Otherwise, it will fall back to the old PostScript printing
 102   code, from which the Pango drawing code was removed.
 103 - Implemented/improved wxDC::DrawRotatedText()
 104 - fixed wxFileDialog::SetWildcard()
 105 - native file dialog is now used if available (Zbigniew Zagorski)
 106 - implemented wxTextCtrl::Freeze() and Thaw(). The GtkTextBuffer
 107   is not a valid one during frozen state. Get a pointer to it right
 108   after wxTextCtrl creation if you really need to. (Mart Raudsepp)
 109 - Changed calls to GTK+ 2.4.x functions so that the code checks at
 110   runtime, which library version is installed so that these functions
 111   are only called with GTK+ 2.4.x installed and should yield linker
 112   errors otherwise.
 113 - wxTextCtrl text insertion efficiency fixed. (Mart Raudsepp)
 114 - Added wxRawBitmap support
 115 - Corrected Input method handler code (for Chinese etc.) and its
 116   interaction with wxWidgets' events.
 117 - wxTE_AUTO_URL implemention for wxGTK2 multiline wxTextCtrls (Mart Raudsepp)
 118
 119 wxMac:

 136   but not mentioned anywhere.
 137 - Added (preliminary) support for sockets
 138
 139 wxUniv:
 140
 141 - wxBU_... button align flags support

 145
 146 wxPalmOS:
 147
 148 - William Osborne has won and new port was born
 149   (see: "wxPalmOS porting challenge")
 150 - polishing of the port (unnecessary 2.4 API compatibility, removed
 151   all wxMSW specific code which was base for the new port)

 301
 302 2.5.2
 303 -----
 304
 305 All:
 306
 307 - Hindi translation added (Dhananjaya Sharma)
 308 - Brazilian Portuguese translation added (E. A. Tacao)
 309 - wxDynamicCast() now uses static_cast<wxObject *> internally and so using it
 310   with anything not deriving from wxObject will fail at compile time (instead
 311   of run-time) now
 312 - when wxUSE_STL == 1 and STL provides quasi-standard hash_map/hash_set,
 313   wxHashMap/wxHashSet are just typedefs for them. This makes impossible
 314   to forward declare these classes.
 315
 316 All (GUI):
 317
 318 - wxHtmlWindow now delays image scaling until rendering,
 319   resulting in much better display of scaled images
 320 - Added UpdateSize to wxSplitterWindow to allow layout while hidden
 321 - implemented Freeze/Thaw() for wxGenericTreeCtrl (Kevin Hock)
 322 - support for KOI8-U encoding added (Yuriy Tkachenko)
 323 - The old wxADJUST_MINSIZE behaviour is now the default behaviour for
 324   sizer items that are windows.  This means that GetAdjustedBestSize
 325   will now be called by default to determine the minimum size that a
 326   window in a sizer should have.  If you want to still use the initial
 327   size (and not the BestSize) then use the wxFIXED_MINSIZE flag.  When
 328   windows are added to a sizer their initial size is made the window's
 329   min size using SetSizeHints, and calls to wxSizer::SetItemMinSize
 330   are also forwarded to SetSizeHints for window items.
 331 - added wxRegEx::GetMatchCount()
 332 - it is now possible to display images in wxHtmlListBox
 333
 334 wxMSW:
 335
 336 - wxWindow::Freeze()/Thaw() can now be nested
 337 - Added wxSP_NO_XP_THEME style to wxSplitterWindow to switch off
 338   XP theming (some applications look bad without 3D borders)
 339 - wxMenuBar::GetLabelTop() doesn't include '&'s in the label any more
 340 - wxRegConf couldn't read global settings without admin privileges and didn't
 341   even try to do it by default -- now it does
 342 - wxTaskBarIcon must be explicitly destroyed now, otherwise the application
 343   won't exit even though there are no top level windows
 344 - wxFileName::GetModificationTime() works with opened files too now
 345 - wxDC::GetClippingBox() now works even for clipping regions created by Windows
 346 - fixed wxFileDataObject in Unicode build (Alex D)
 347 - subindented paragraphs support (Tim Kosse)
 348
 349 wxGTK:
 350
 351 - added support for wxTE_RIGHT and wxTE_CENTRE styles under GTK2 (Mart Raudsepp)
 352
 353 wxMotif:
 354
 355 - removed wxMenuItem::DeleteSubMenu()
 356 - wxButtons use Motif default size, which is smaller than it used to be
 357   and closer to wxMSW/wxGTK look. This can be disabled by setting
 358   motif.largebuttons system option to 1 (see wxSystemOptions).
 359
 360 wxUniv/X11:
 361
 362 - implemented DrawRoundedRectangle() (clawghoul)
 363
 364 wxHTML:
 365
 366 - improved tables and lists layout algorithms (Tim Kosse)
 367 - <div> handling fix (Xavier Nodet)
 368
 369 Unix:
 370
 371 - fixed priorities of mailcap entries (David Hart)
 372 - added "wx-config --libs=std,<extra>" syntax (i.e. support for "std")
 373
 374 wxODBC:
 375
 376 - Full Unicode support is now available
 377 - BLOB support is working
 378
 379

 510 -----
 511
 512 All:
 513

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

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

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

 672 - Windows XP manifest is now included in wx.rc; it is no longer necessary
 673   to ship .exe.manifest file with applications to support XP themes
 674 - wxLocale::Init no longer reports error if trying to set Unicode-only locale
 675   or if user's default locale is Unicode-only
 676 - improved border handling under Windows XP
 677 - partial fix for wxNotebook pages looking bad under XP: wxUSE_UXTHEME
 678   enables XP theme engine code, and wxUSE_UXTHEME_AUTO tells

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

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

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

1525 wxGTK:
1526
1527 - wxExecute improved.
1528
1529 wxMSW:
1530
1531 - Fixed wxWindow::IsShown (::IsWindowVisible doesn't behave as
1532   expected).
1533 - Changed VC++ makefiles (.vc) so that it's possible to have
1534   debug/release/DLL versions of the library available simultaneously,
1535   with names wx.lib, wx_d.lib, wx200.lib(dll), wx200_d.lib(dll).
1536 - Added BC++ 5 IDE files and instructions.
1537 - Fixed wxChoice, wxComboBox constructor bugs (m_noStrings initialisation).
1538 - Fixed focus-related crash.
1539
1540 wxMotif:

1548 - Added include filenames to class reference.
1549 - wxHelpController API changed: SetBrowser becomes SetViewer,
1550   DisplaySection works for WinHelp, help sample compiles under Windows
1551   (though doesn't display help yet).
1552
1553 Beta 4, February 12th 1999
1554 --------------------------
1555
1556 wxGTK:
1557
1558 - Miscellaneous fixes.
1559
1560 wxMSW:
1561
1562 - Makefiles for more compilers and samples; Cygwin makefiles
1563   rationalised.
1564 - Added VC++ project file for compiling wxWidgets as DLL.
1565
1566 wxMotif:

1568 - Added OnEraseBackground invocation.
1569 - Added wxRETAINED implementation for wxScrolledWindow.
1570 - Cured scrolling display problem by adding XmUpdateDisplay.
1571 - Tried to make lex-ing in the makefile more generic (command line
1572   syntax should apply to both lex and flex).
1573 - Changed file selector colours for consistency (except for buttons:
1574   crashes for some reason).
1575 - Fixed wxMotif version of wxImage::ConvertToBitmap (used new instead
1576   of malloc, which causes memory problems).
1577
1578 General:
1579
1580 - Further doc improvements.
1581 - wxGenericValidator added.
1582 - Added wxImageModule to image.cpp, so adds/cleans up standard handlers
1583   automatically.
1584
1585 Beta 3, January 31st 1999
1586 -------------------------
1587
1588 wxGTK:

1595
1596 - wxRegConfig DeleteAll bug fixed.
1597 - Makefiles for more compilers.
1598 - TWIN32 support added.

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