   3 -------------------------------------------------------------------
   4
   5 2.5.5
   6 -----
   7
   8 All:
   9
  10 - Added GetIcon, GetBitmap to wxImageList. wxGenericImageList's original
  11   GetBitmap is renamed GetBitmapPtr.
  12 - Added XPM data constructor to wxImage.
  13 - wxURI::GetUser and wxURI::HasUser have been renamed to wxURI::GetUserInfo and wxURI::HasUserInfo respectively so that wxURI::GetUser returns the old username that were in the HTTP specification along with wxURI::GetPassword (Note that if you used wxURI::GetUser from 2.5.3 you should rename all instances of it to wxURI::GetUserInfo).
  14
  15
  16 wxPalmOS:
  17
  18 - native wxRadioBox implementation
  19
  20
  21 2.5.4
  22 -----
  23
  24 All:
  25
  26 - wxEvent and derived classes don't have public members any more, you must
  27   use accessors methods now (Mart Raudsepp)
  28 - new classes for reading and writing ZIP files (M.J.Wetherell)
  29 - large files support for wxFFile (M.J.Wetherell)
  30 - classes in the manual are now cross-referenced (Zbigniew Zagórski)
  31 - Norwegian (Bokmål) translation added (Hans F. Nordhaug)
  32 - wxDynamicLibrary::HasSymbol() added
  33 - added wxEXEC_NODISABLE flag to be used with wxExecute(wxEXEC_SYNC)
  34 - added wxTextInputStream::operator>>(wchar_t) for compilers which support this
  35 - added wxURI, a class for dealing with Uniform Resource Identifiers
  36 - changed wxURL to inherit from wxURI and provide assignment and comparison
  37 - implemented wxConvUTF7 (modified patch from Fredrik Roubert)
  38 - added versions of MB2WC and WC2MB for wxMBConv that for embedded null chars
  39 - Unicode support in wxODBC is now fully implemented
  40 - A new data type specific to wxWidgets called SQL_C_WXCHAR has been introduced.
  41   SQL_C_WXCHAR should be used rather than SQL_C_CHAR to ensure transparent
  42   behavior between Unicode and non-unicode builds
  43 - BLOB example added to samples/db (thanks to Casey ODonnell)
  44 - use wxStream::GetLength() instead of deprecated GetSize()
  45 - wxGetOsDescription() is now more precise (Olly Betts)
  46 - XRC supports system fonts and colours (Ray Gilbert)
  47 - Added flags argument to wxKill/wxProcess::Kill to kill child processes.
  48 - Added wxPrintFactory classes so that it is possible to add a new
  49   print system backend at run-time. This was required by the new GNOME
  50   printing stuff in the GTK port.
  51 - Deprecated print setup dialog.
  52 - Added support to the wxODBC classes for Firebird 1.5 database
  53 - The samples\db sample program now includes an optional example of using a BLOB
  54   datatype (if BLOB support is enabled and supported by the database)
  55 - added wxDynamicLibrary::ListLoaded()
  56 - wxGetPowerType() and wxGetBatteryState() addition
  57 - wxSystemSettings::GetSystem*() members deprecated and replaced with
  58   wxSystemSettings::Get*()
  59 - wxWindowBase::DoGetBestSize now includes the difference (if any) between
  60   the client size and total size of the window.  Code that sets the
  61   client size using the best size, or that added extra space to sizers
  62   to compensate for this bug may need to be changed.
  63 - Changed calculation of scrolling area to not clip away some bits
  64   due to a rounding error.
  65 - Changed GetVirtualSize() to return client size by default until
  66   SetVirtualSize() gets called. From then on it will only return that.
  67 - Various changes to how wxListCtrl and wxTreeCtrl react to right
  68   mouse clicks and left mouse click for starting a drag operation.
  69 - "Alt" key (VK_MENU) now results in WXK_ALT keyboard event, not WXK_MENU
  70 - wxFFile::ReadAll() now takes an optional wxMBConv parameter
  71 - wxCommandProcessor::MarkAsSaved() and IsDirty() added (Angela Wrobel)

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

  96 Unix:
  97
  98 - wxPuts() now correctly outputs trailing new line in Unicode build
  99
 100 wxGTK:
 101
 102 - Added printing support by way of using libgnomeprint. The library
 103   now checks at runtime, if the library is installed and will use it
 104   if it is. Otherwise, it will fall back to the old PostScript printing
 105   code, from which the Pango drawing code was removed.
 106 - Implemented/improved wxDC::DrawRotatedText()
 107 - fixed wxFileDialog::SetWildcard()
 108 - native file dialog is now used if available (Zbigniew Zagorski)
 109 - implemented wxTextCtrl::Freeze() and Thaw(). The GtkTextBuffer
 110   is not a valid one during frozen state. Get a pointer to it right
 111   after wxTextCtrl creation if you really need to. (Mart Raudsepp)
 112 - Changed calls to GTK+ 2.4.x functions so that the code checks at
 113   runtime, which library version is installed so that these functions
 114   are only called with GTK+ 2.4.x installed and should yield linker
 115   errors otherwise.
 116 - wxTextCtrl text insertion efficiency fixed. (Mart Raudsepp)
 117 - Added wxRawBitmap support
 118 - Corrected Input method handler code (for Chinese etc.) and its
 119   interaction with wxWidgets' events.
 120 - wxTE_AUTO_URL implemention for wxGTK2 multiline wxTextCtrls (Mart Raudsepp)
 121
 122 wxMac:

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

 192
 193 - added wxWindow::MoveBefore/AfterInTabOrder() to change tab navigation order
 194 - added wxTaskBarIcon::CreatePopupMenu which is now the recommended way

 304
 305 2.5.2
 306 -----
 307
 308 All:
 309
 310 - Hindi translation added (Dhananjaya Sharma)
 311 - Brazilian Portuguese translation added (E. A. Tacao)
 312 - wxDynamicCast() now uses static_cast<wxObject *> internally and so using it
 313   with anything not deriving from wxObject will fail at compile time (instead
 314   of run-time) now
 315 - when wxUSE_STL == 1 and STL provides quasi-standard hash_map/hash_set,
 316   wxHashMap/wxHashSet are just typedefs for them. This makes impossible
 317   to forward declare these classes.
 318
 319 All (GUI):
 320
 321 - wxHtmlWindow now delays image scaling until rendering,
 322   resulting in much better display of scaled images
 323 - Added UpdateSize to wxSplitterWindow to allow layout while hidden
 324 - implemented Freeze/Thaw() for wxGenericTreeCtrl (Kevin Hock)
 325 - support for KOI8-U encoding added (Yuriy Tkachenko)
 326 - The old wxADJUST_MINSIZE behaviour is now the default behaviour for
 327   sizer items that are windows.  This means that GetAdjustedBestSize
 328   will now be called by default to determine the minimum size that a
 329   window in a sizer should have.  If you want to still use the initial
 330   size (and not the BestSize) then use the wxFIXED_MINSIZE flag.  When
 331   windows are added to a sizer their initial size is made the window's
 332   min size using SetSizeHints, and calls to wxSizer::SetItemMinSize
 333   are also forwarded to SetSizeHints for window items.
 334 - added wxRegEx::GetMatchCount()
 335 - it is now possible to display images in wxHtmlListBox
 336
 337 wxMSW:
 338
 339 - wxWindow::Freeze()/Thaw() can now be nested
 340 - Added wxSP_NO_XP_THEME style to wxSplitterWindow to switch off
 341   XP theming (some applications look bad without 3D borders)
 342 - wxMenuBar::GetLabelTop() doesn't include '&'s in the label any more
 343 - wxRegConf couldn't read global settings without admin privileges and didn't
 344   even try to do it by default -- now it does
 345 - wxTaskBarIcon must be explicitly destroyed now, otherwise the application
 346   won't exit even though there are no top level windows
 347 - wxFileName::GetModificationTime() works with opened files too now
 348 - wxDC::GetClippingBox() now works even for clipping regions created by Windows
 349 - fixed wxFileDataObject in Unicode build (Alex D)
 350 - subindented paragraphs support (Tim Kosse)
 351
 352 wxGTK:
 353
 354 - added support for wxTE_RIGHT and wxTE_CENTRE styles under GTK2 (Mart Raudsepp)
 355
 356 wxMotif:
 357
 358 - removed wxMenuItem::DeleteSubMenu()
 359 - wxButtons use Motif default size, which is smaller than it used to be
 360   and closer to wxMSW/wxGTK look. This can be disabled by setting
 361   motif.largebuttons system option to 1 (see wxSystemOptions).
 362
 363 wxUniv/X11:
 364
 365 - implemented DrawRoundedRectangle() (clawghoul)
 366
 367 wxHTML:
 368
 369 - improved tables and lists layout algorithms (Tim Kosse)
 370 - <div> handling fix (Xavier Nodet)
 371
 372 Unix:
 373
 374 - fixed priorities of mailcap entries (David Hart)
 375 - added "wx-config --libs=std,<extra>" syntax (i.e. support for "std")
 376
 377 wxODBC:
 378
 379 - Full Unicode support is now available
 380 - BLOB support is working
 381
 382

 513 -----
 514
 515 All:
 516

 543   std::vector, wxList from std::list. In addition wxHashTable will be
 544   implemented in terms of wxHashMap.
 545 - Added wxList::compatibility_iterator. Can be used like wxNode* (except
 546   it can't be delete()d). It permits writing code which will work
 547   both with wxUSE_STL==1 and wxUSE_STL==0.
 548
 549 wxBase:
 550

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

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

 683 - disable wxNB_RIGHT, wxNB_LEFT, wxNB_BOTTOM notebook styles under Windows XP
 684 - fixed release mode build with VC 7.x (Martin Ecker)

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

 716 OLD CHANGES
 717 ===========
 718
 719 INCOMPATIBLE CHANGES SINCE 2.2.x
 720 ================================
 721
 722     Please take a few minutes to read the following list, especially
 723     paying attention to the most important changes which are marked
 724     with '!' in the first column.
 725
 726     Also please note that you should ensure that WXWIN_COMPATIBILITY_2_2
 727     is defined to 1 if you wish to retain maximal compatibility with 2.2
 728     series -- however you are also strongly encouraged to try to compile
 729     your code without this define as it won't be default any longer in
 730     2.6 release.
 731
 732     NB: if you want to build your program with different major versions
 733         of wxWidgets you will probably find the wxCHECK_VERSION() macro
 734         (see the documentation) useful.
 735
 736
 737 wxBase:
 738
 739 ! wxArray<T>::Remove(size_t) has been removed to fix compilation problems
 740   under 64 bit architectures, please replace it with RemoveAt() in your
 741   code.
 742
 743 ! wxArray<T> macros have been changed to fix runtime problems under 64 bit
 744   architectures and as a side effect of this WX_DEFINE_ARRAY() can only be
 745   used now for the pointer types, WX_DEFINE_ARRAY_INT should be used for the
 746   arrays containing non-pointers.
 747
 748 - wxObject::CopyObject() and Clone() methods were removed because they
 749   simply don't make sense for all objects
 750
 751 - wxEvent now has a pure virtual Clone() method which must be implemented
 752   by all derived classes, if you have user-defined event classes please
 753   add "wxEvent *Clone() const { return new MyEvent(*this); }" line to them
 754
 755 - small change to wxStopWatch::Pause() semantics, please see the documentation
 756
 757 - unlikely but possible incompatibility: the definition of TRUE has changed
 758   from "1" to "(bool)1" (and the same thing for FALSE), so the code which
 759   could be erroneously compiled previously such as doing "return FALSE" from
 760   a function returning a pointer would stop compiling now (but this change
 761   is not supposed to have any effects on valid code)
 762
 763 - another minor change: wxApp::OnAssert() has a new "cond" argument, you
 764   must modify YourApp::OnAssert() signature if you were using it to override
 765   the default assert handling.
 766
 767 All (GUI):
 768
 769 ! the event type constants are not constants any more but are dynamically
 770   allocated during run-time which means that they can't be used as case labels
 771   in the switch()es, you must rewrite them to use if()s instead
 772
 773   You may also define WXWIN_COMPATIBILITY_EVENT_TYPES to get the old behaviour
 774   but this is strongly discouraged, please consider changing your code
 775   instead!
 776
 777 ! wxDialog does not derive from wxPanel any longer - if you were using it in
 778   your code, please update it. The quick fix for the most cases is to replace
 779   the occurrences of wxPanel with wxWindow.
 780
 781 ! if you handle (and don't skip) EVT_KEY_DOWN, the EVT_CHAR event is not
 782   generated at all, so you must call event.Skip() in your OnKeyDown() if
 783   you want to get OnChar() as well
 784
 785 - in general, the key events sent for the various non ASCII key combinations
 786   have been changed to make them consistent over all supported platforms,
 787   please see the wxKeyEvent documentation for details
 788
 789 - wxYES_NO is now wxYES | wxNO and the manifest values of both wxYES and wxNO
 790   have changed (to fix some unfortunate clashes), please check your code to
 791   ensure that no tests for wxYES or wxNO are broken: for example, the following
 792   will *NOT* work any longer:
 793
 794         if ( flags & wxYES_NO )
 795                 ... do something ...
 796         if ( flags & wxYES )
 797                 ... do something else ...
 798
 799 - static wxWizard::Create() doesn't exist any more, the wizards are created
 800   in the same way as all the other wxWindow objects, i.e. by directly using
 801   the ctor
 802
 803 - wxGLCanvas now derives directly from wxWindow, not wxScrolledWindow
 804
 805 - wxGridCellAttrProvider class API changed, you will need to update your code
 806   if you derived any classes from it
 807
 808 - wxImage::ComputeHistogram()'s signature changed to
 809   unsigned long ComputeHistogram(wxImageHistogram&) const
 810
 811 - wxEvtHandler cannot be copied/assigned any longer - this never worked but
 812   now it results in compile-time error instead of run-time crashes
 813
 814 - WXK_NUMLOCK and WXK_SCROLL keys no longer result in EVT_CHAR() events,
 815   they only generate EVT_KEY_DOWN/UP() ones
 816
 817 - the dialogs use wxApp::GetTopWindow() as the parent implicitly if the
 818   parent specified is NULL, use wxDIALOG_NO_PARENT style to prevent this
 819   from happening
 820
 821 - several obsolete synonyms are only retained in WXWIN_COMPATIBILITY_2_2 mode:
 822   for example, use wxScrolledWindow::GetViewStart() now instead of ViewStart()
 823   and GetCount() instead of Number() in many classes
 824
 825 - wxCmdLineParser does not use wxLog to output messages anymore.
 826   to obtain the previous behaviour, add
 827   wxMessageOutput::Set(new wxMessageOutputLog); to your program
 828   (you will need to #include <wx/msgout.h>)
 829
 830 wxMSW:
 831
 832 ! build system changed: setup.h is not a static file in include/wx any more
 833   but is created as part of the build process under lib/<toolkit>/wx
 834   where <toolkit> is of the form (msw|univ)[dll][u][d]. You'll need to update
 835   the include path in your make/project files appropriately. Furthermore,
 836   xpm.lib is no longer used by wxMSW, it was superseded by the wxXPMDecoder
 837   class. You'll need to remove all references to xpm.lib from your
 838   make/project files. Finally, the library names have changed as well and now
 839   use the following consistent naming convention: wxmsw[ver][u][d].(lib|dll)
 840   where 'u' appears for Unicode version, 'd' -- for the debug one and version
 841   is only present for the DLLs builds.
 842
 843 - child frames appear in the taskbar by default now, use wxFRAME_NO_TASKBAR
 844   style to avoid it
 845
 846 - all overloads of wxDC::SetClippingRegion() combine the given region with the
 847   previously selected one instead of replacing it
 848
 849 - wxGetHomeDir() uses HOME environment variable and if it is set will not
 850   return the programs directory any longer but its value (this function has
 851   never been meant to return the programs directory anyhow)
 852
 853 - wxHTML apps don't need to include wx/html/msw/wxhtml.rc in resources file
 854   anymore. The file was removed from wxMSW
 855
 856
 857 Unix ports:
 858
 859 ! You should use `wx-config --cxxflags` in your makefiles instead of
 860   `wx-config --cflags` for compiling C++ files. CXXFLAGS contains CFLAGS
 861   and the compiler flags for C++ files only, CFLAGS should still be used
 862   to compile pure C files.
 863
 864
 865 wxThread and related classes:
 866
 867 - The thread-related classes have been heavily changed since 2.2.x versions
 868   as the old code had many serious problems. This could have resulted in
 869   semantical changes other than those mentioned here, please review use of
 870   wxThread, wxMutex and wxCondition classes in your code.
 871
 872 ! wxCondition now *must* be used with a mutex, please read the (updated) class
 873   documentation for details and revise your code accordingly: this change was
 874   unfortunately needed as it was impossible to ensure the correct behaviour
 875   (i.e. absence of race conditions) using the old API.
 876
 877 - wxMutex is not recursive any more in POSIX implementation (it hasn't been
 878   recursive in 2.2.x but was in 2.3.1 and 2.3.2), please refer to the class
 879   documentation for the discussion of the recursive mutexes.
 880
 881 - wxMutex::IsLocked() doesn't exist any more and should have never existed:
 882   this is was unique example of a thread-unsafe-by-design method.
 883

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

1545 - Cured asynchronous wxExecute crash.
1546 - Added repaint event handlers to wxFrame, wxMDIChildFrame.
1547
1548 General:
1549

1551 - Added include filenames to class reference.
1552 - wxHelpController API changed: SetBrowser becomes SetViewer,
1553   DisplaySection works for WinHelp, help sample compiles under Windows
1554   (though doesn't display help yet).
1555
1556 Beta 4, February 12th 1999
1557 --------------------------
1558
1559 wxGTK:
1560
1561 - Miscellaneous fixes.
1562
1563 wxMSW:
1564
1565 - Makefiles for more compilers and samples; Cygwin makefiles
1566   rationalised.
1567 - Added VC++ project file for compiling wxWidgets as DLL.
1568
1569 wxMotif:

1571 - Added OnEraseBackground invocation.
1572 - Added wxRETAINED implementation for wxScrolledWindow.
1573 - Cured scrolling display problem by adding XmUpdateDisplay.
1574 - Tried to make lex-ing in the makefile more generic (command line
1575   syntax should apply to both lex and flex).
1576 - Changed file selector colours for consistency (except for buttons:
1577   crashes for some reason).
1578 - Fixed wxMotif version of wxImage::ConvertToBitmap (used new instead
1579   of malloc, which causes memory problems).
1580
1581 General:
1582
1583 - Further doc improvements.
1584 - wxGenericValidator added.
1585 - Added wxImageModule to image.cpp, so adds/cleans up standard handlers
1586   automatically.
1587
1588 Beta 3, January 31st 1999
1589 -------------------------
1590
1591 wxGTK:

1598
1599 - wxRegConfig DeleteAll bug fixed.
1600 - Makefiles for more compilers.
1601 - TWIN32 support added.

1621 --------------------
1622
1623 wxGTK:
1624
1625 wxMSW:
1626
1627 - 16-bit BC++ compilation/linking works albeit without the resource system.
1628
1629 wxMotif:
1630
1631 - Cured wxScreenDC origin problem so e.g. sash window sash is drawn at
1632   the right place.
1633 - Cured some widget table clashes.
1634 - Added thread support (Robert).
1635 - wxPoem sample now works.
1636
1637 General:
1638
1639 - Rearranged documentation a bit.
1640 - Sash window uses area of first frame/dialog to paint over when drawing
1641   the dragged sash, not just the sash window itself (it clipped to the right
1642   or below).
1643 - Made resource sample use the correct Cancel button id.
1644 - Moved wxProp to main library (generic directory), created proplist
1645   sample.
1646 - Added bombs and fractal samples.
1647
1648 Beta 1, December 24th 1998
1649 --------------------------
1650
1651 wxGTK:
1652
1653 - Various
1654
1655 wxMSW, wxMotif: not in sync with this release.
1656
1657
1658 Alpha 18, December 29th 1998
1659 ----------------------------
1660
1661 wxMSW:
1662
1663 - Win16 support working again (VC++ 1.5)
1664 - Win16 now uses generic wxNotebook, wxListCtrl,
1665   wxTreeCtrl -- more or less working now, although
1666   a little work on wxNotebook is still needed.
1667   Under 16-bit Windows, get assertion when you click
1668   on a tab.
1669 - Wrote 16-bit BC++ makefiles: samples don't yet link.
1670 - Added CodeWarrior support to distribution courtesy
1671   of Stefan Csomor.
1672
1673 wxMotif:
1674
1675 - Cured scrolling problem: scrollbars now show/hide themselves
1676   without (permanently) resizing the window.
1677 - Removed some commented-out lines in wxScrolledWindow::AdjustScrollbars
1678   that disabled scrollbar paging.
1679 - Set background colour of drawing area in wxWindow, so e.g. wxListCtrl
1680   colours correctly.
1681 - Removed major bug whereby dialogs were unmanaged automatically
1682   when any button was pressed.
1683 - Fixed colours of wxWindow scrollbars, made list and text controls
1684   have a white background.
1685 - Fixed dialog colour setting.
1686 - Added settable fonts and colours for wxMenu/wxMenuBar. Now
1687   they have sensible colours by default.
1688 - Fixed a bug in wxStaticBox.
1689 - Cured wxTreeCtrl bug: now works pretty well!
1690 - Debugged DrawEllipticArc (a ! in the wrong place).
1691 - Added SetClippingRegion( const wxRegion& region ).
1692 - Added wxPoint, wxSize, wxRect versions of SetSize etc.
1693
1694 Alpha 17, November 22nd 1998
1695 ----------------------------
1696
1697 wxMSW:
1698
1699 - More documentation updates, especially for
1700   wxLayoutWindow classes and debugging facilities.
1701 - Changed wxDebugContext to use wxDebugLog instead
1702   of wxTrace.
1703 - Now supports VC++ 6.0, and hopefully BC++ 5.0.
1704   However, DLL support may be broken for BC++ since
1705   VC++ 6 required changing of WXDLLEXPORT keyword
1706   position.
1707 - Numerous miscellaneous changes.
1708
1709 wxMotif:
1710
1711 - Reimplemented MDI using wxNotebook instead of the MDI widgets, which
1712   were too buggy (probably not design for dynamic addition/removal of
1713   child frames).
1714 - Some improvements to the wxNotebook implementation.
1715 - wxToolBar now uses a bulletin board instead of a form, in an attempt
1716   to make it possible to add ordinary wxControls to a toolbar.
1717 - Cured problem with not being able to use global memory operators,
1718   by defining two more global operators, so that the delete will match
1719   the debugging implementation.
1720 - Added wxUSE_DEBUG_NEW_ALWAYS so we can distinguish between using
1721   global memory operators (usually OK) and #defining new to be
1722   WXDEBUG_NEW (sometimes it might not be OK).
1723 - Added time.cpp to makefile; set wxUSE_DATETIME to 1.
1724 - Added a parent-existence check to popup menu code to make it not crash.
1725 - Added some optimization in wxWindow::SetSize to produce less flicker.
1726   It remains to be seen whether this produces any resize bugs.
1727
1728 It's a long time since I updated this file. Previously done:
1729
1730 - wxFrame, wxDialog done.
1731 - wxScrolledWindow done (but backing pixmap not used at present).
1732 - wxBitmap done though could be tidied it up at some point.
1733 - Most basic controls are there, if not rigorously tested.
1734 - Some MDI support (menus appear on child frames at present).
1735 - wxNotebook almost done.
1736 - wxToolBar done (horizontal only, which would be easy to extend
1737   to vertical toolbars).
1738
1739 More recently:
1740
1741 - Colour and font changing done (question mark over what happens
1742   to scrollbars).
1743 - Accelerators done (for menu items and buttons). Also event loop
1744   tidied up in wxApp so that events are filtered through ProcessXEvent.
1745 - wxWindow::GetUpdateRegion should now work.
1746
1747 Alpha 16, September 8th 1998
1748 ----------------------------
1749
1750 wxMSW:
1751

1758 - wxProp updates for correct working with wxGTK.
1759
1760 wxMotif:
1761
1762 - First start at Motif port.
1763 - Made makefiles for wxMotif source directory and minimal sample.
1764 - First go at wxApp, wxWindow, wxDialog, wxPen, wxBrush, wxFont,
1765   wxColour, wxButton, wxCheckBox, wxTextCtrl, wxStaticText,
1766   wxMenu, wxMenuItem, wxMenuBar
1767
1768 Alpha 15, August 31st 1998
1769 --------------------------
1770
1771 wxMSW:
1772
1773 - wxBitmap debugged.
1774 - wxDC::GetDepth added.
1775 - Contribution added whereby wxBitmap will be
1776   converted to DC depth if they don't match.
1777 - wxConfig API improved, documentation updated.
1778 - Printing classes name conventions cleaned up.
1779 - wxUpdateUIEvent now derives from wxCommandEvent
1780   so event can travel up the window hierarchy.
1781
1782 Alpha 14, July 31st 1998
1783 ------------------------
1784
1785 wxMSW:
1786
1787 - Toolbar API has been simplified, and now
1788   wxFrame::GetClientArea returns the available client
1789   area when toolbar, status bar etc. have been accounted for.
1790   wxFrame::CreateToolBar added in line with CreateStatusBar.
1791 - Documentation updates, incl. for wxToolBar.
1792 - New wxAcceleratorTable class plus wxFrame::SetAcceleratorTable.
1793 - Various additions from other folk, e.g. streams, wxConfig
1794   changes, wxNotebook.
1795 - Added wxDocMDIParentFrame, wxDocMDIChildFrame for doc/view.
1796
1797 Alpha 13, July 8th 1998
1798 -----------------------
1799
1800 wxMSW:
1801
1802 - Implemented wxPoint as identical to POINT on Windows, and
1803   altered wxDC wxPoint functions to use wxPoint directly in
1804   Windows functions, for efficiency.
1805 - Cured wxASSERT bug in wxStatusBar95.
1806 - #ifdefed out some bits in oleutils.cpp for compilers that
1807   don't support it.
1808 - Added some operators to wxPoint, wxSize.
1809 - Added inline wxDC functions using wxPoint, wxSize, wxRect.
1810
1811 Alpha 12, July 7th 1998
1812 -----------------------
1813
1814 wxMSW:
1815
1816 - Added wxApp::GetComCtl32Version, and wxTB_FLAT style, so can
1817   have flat toolbars on Win98 or Win95 with IE >= 3 installed.
1818
1819 Alpha 11, July 3rd 1998
1820 -----------------------
1821
1822 wxMSW:
1823
1824 - Added thread.h, thread.cpp.
1825 - Changed Enabled, Checked to IsEnabled, IsChecked in wxMenu,
1826   wxMenuBar.
1827 - Changed wxMenuItem::SetBackColor to SetBackgroundColour,
1828   SetTextColor to SetTextColour, and added or made public several
1829   wxMenuItem accessors.
1830 - Added two overloads to wxRegion::Contains. Added
1831   wxRegion::IsEmpty for a more consistent naming convention.
1832 - Added Vadim's wxDataObject and wxDropSource.
1833 - ENTER/LEAVE events now work.
1834 - Cured wxMemoryDC bug where the DC wasn't being deleted.
1835 - Cured wxGauge SetSize major bugginess.
1836 - Cured problem where if a GDI object was created on the stack,
1837   then went out of scope, then another object was selected into
1838   the DC, GDI objects would leak. This is because the assignment
1839   to e.g. wxDC::m_pen would delete the GDI object without it first
1840   being selected out of the DC. Cured by selecting the old DC object
1841   first, then doing the assignment.
1842 - Split up wxGaugeMSW, wxGauge95, wxSliderMSW, wxSlider95
1843 - Various other bug fixes and additions.
1844
1845 Generic:
1846
1847 - Major work on Dialog Editor (still plenty to go).
1848 - Expanded documentation a bit more.
1849
1850 Alpha 10, May 7th 1998
1851 ----------------------
1852
1853 wxMSW:
1854
1855 - Added desiredWidth, desiredHeight parameters to wxBitmapHandler
1856   and wxIcon functions so that you can specify what size of
1857   icon should be loaded. Probably will remain a Windows-specific thing.
1858 - wxStatusBar95 now works for MDI frames.
1859 - Toolbars in MDI frames now behave normally. They still
1860   require application-supplied positioning code though.
1861 - Changed installation instructions, makefiles and batch files
1862   for compiling with Gnu-Win32/Mingw32/EGCS. Also timercmn.cpp
1863   change to support Mingw32/EGCS. Bison now used by default.
1864
1865 Alpha 9, April 27th 1998
1866 ------------------------
1867
1868 wxMSW:
1869
1870 - Cured bug in wxStatusBar95 that caused a crash if multiple
1871   fields were used.
1872 - Added Gnu-Win32 b19/Mingw32 support by changing resource
1873   compilation and pragmas.
1874 - Cured wxMenu bug introduced in alpha 8 - didn't respond to
1875   commands because VZ changed the id setting in wxMenu::MSWCommand.
1876
1877 Generic:
1878
1879 - Corrected some bugs, such as the wxModule compilation problem.
1880 - Added Gnu-Win32 b19/Mingw32 support by changing resource
1881   compilation and pragmas.
1882 - Changed SIZEOF to WXSIZEOF.
1883
1884 Alpha 8, April 17th 1998
1885 ------------------------
1886
1887 wxMSW:
1888
1889 - Added IsNull to wxGDIObject to check if the ref data is present or not.
1890 - Added PNG handler and sample - doesn't work for 16-bit PNGs for
1891   some reason :-(
1892 - Added wxJoystick class and event handling, and simple demo.
1893 - Added simple wxWave class. Needs Stop() function.
1894 - Added wxModule (module.h/module.cpp) to allow definition
1895   of modules to be initialized and cleaned up on wxWidgets
1896   startup/exit.
1897 - Start of Mingw32 compatibility (see minimal and dialogs samples
1898   makefile.m95 files, and install.txt).
1899 - Note: Windows printing has stopped working... will investigate.
1900 VADIM'S CHANGES:
1901 - Updated wxString: bug fixes, added wxArrayString, some
1902   compatibility functions.
1903 - Updated log.h/cpp, added wxApp::CreateLogTarget.
1904 - file.h: new wxTempFile class.
1905 - defs.h: added wxSB_SIZE_GRIP for wxStatusBar95
1906 - statbr95: wxStatusBar95 control.
1907 - registry.h/cpp: wxRegKey class for Win95 registry.
1908 - listbox.cpp: corrected some bugs with owner-drawn listboxes.
1909 - wxConfig and wxFileConfig classes.
1910
1911 Generic:
1912
1913 - Added src/other/png, src/other/zlib directories.
1914 - Added samples/png.
1915 - IMPORTANT: Changed 'no id' number from 0 to -1, in wxEVT_ macros.
1916   Porters, please check particularly your wxTreeCtrl and wxListCtrl
1917   header files.
1918 - Added modules.h/cpp, config.cpp, fileconf.cpp, textfile.cpp/h.
1919
1920 Alpha 7, March 30th 1998
1921 ------------------------
1922
1923 wxMSW:
1924
1925 - Added tab classes, tab sample.
1926 - Now can return FALSE from OnInit and windows will be
1927   cleaned up properly before exit.
1928 - Improved border handling so panels don't get borders
1929   automatically.
1930 - Debugged MDI activation from Window menu.
1931 - Changes to memory debug handling, including checking for
1932   memory leaks on application exit - but see issues.txt for
1933   unresolved issues.
1934 - Added wxTaskBarIcon (taskbar.cpp/h, plus samples/taskbar)
1935   to allow maintenance of an icon in the Windows 95 taskbar
1936   tray area.
1937 - Got MFC sample working (MFC and wxWidgets in the same
1938   application), partly by tweaking ntwxwin.mak settings.
1939 - Got DLL compilation working again (VC++).
1940 - Changed wxProp/Dialog Editor filenames.
1941
1942 Generic:
1943
1944 - Added tab classes, tab sample.
1945 - Revised memory.cpp, memory.h slightly; memory.h now #defines
1946   new to WXDEBUG_NEW in DEBUG mode. Windows implementation app.cpp
1947   now checks for leaks on exit. Added memcheck sample.
1948   See src/msw/issues.txt for more details.
1949 - resource.h, resource.cpp changed to make wxDefaultResourceTable
1950   a pointer. Now initialize resource system with
1951   wxInitializeResourceSystem and wxCleanUpResourceSystem, to
1952   allow better control of memory.
1953 - wxString now derives from wxObject, to enable memory leak
1954   checking.
1955 - Added some #include fixes in various files, plus changed
1956   float to long in wxToolBar files.
1957
1958 Alpha 6, March 10th 1998
1959 ------------------------
1960
1961 wxMSW:
1962
1963 - Found stack error bug - stopped unwanted OnIdle recursion.
1964 - Removed bug in wxTreeCtrl::InsertItem I added in alpha 5.
1965 - Changed exit behaviour in wxApp/wxFrame/wxDialog. Now will
1966   check if the number of top-level windows is zero before
1967   exiting. Also, wxApp::GetTopWindow will return either
1968   m_topWindow or the first member of wxTopLevelWindows, so you
1969   don't have to call wxApp::SetTopWindow.
1970 - Added dynarray.h/dynarray.cpp (from Vadim).
1971 - Added first cut at OLE drag and drop (from Vadim). dnd sample
1972   added. Drop target only at this stage. See src/msw/ole/*.cpp,
1973   wx/include/msw/ole/*.h. WIN32 only because of UUID usage.
1974   Doesn't work with GnuWin32 - no appropriate headers e.g. for
1975   IUnknown.
1976   Doesn't work with BC++ either - crashes on program startup.
1977 - Added Vadim's owner-draw modifications - will probably remain
1978   Windows-only. This enhances wxMenu, wxListBox. See ownerdrw sample.
1979 - Added wxLB_OWNERDRAW for owner-draw listboxes.
1980 - Vadim's wxCheckListBox derives from wxListBox. See checklst sample.
1981   Doesn't entirely work for WIN16.
1982 - Vadim has added wxMenuItem as a separate file menuitem.cpp. It
1983   can also be used as an argument to wxMenu::Append, not just for
1984   internal implementation.
1985 - Some #ifdefs done for MINGW32 compilation (just alter OPTIONS
1986   in makeg95.env, together with mingw32.bat). However, resource
1987   binding is not working yet so most apps with dialogs crash.
1988
1989 Generic:
1990
1991 - Added Vadim's dynarray.h, dynarray.cpp.
1992 - Added Vadim's menuitem.cpp.
1993 - Added Windows-specific wxCheckListBox,
1994   owner-draw wxListBox, and drag-and-drop
1995   (see docs/msw/changes.txt).
1996
1997 Alpha 5, 14th February 1998
1998 --------------------------
1999
2000 wxMSW:
2001
2002 - GENERIC AND MSW-SPECIFIC CODE NOW TREATED AS TWO SEPARATE
2003   DISTRIBUTIONS. This change log will therefore now refer to
2004   the Windows-specific code only. See docs/changes.txt for generic
2005   changes.
2006 - Removed Windows-specific reference counting system (GDI
2007   resources were cleaned up in idle time) - minimal
2008   advantages now we have a wxWin reference counting system.
2009 - Added missing WXDLLEXPORT keywords so DLL compilation works
2010   again.
2011 - Removed most warnings for GnuWin32 compilation.
2012 - Added wxRegion/wxRegionIterator, but haven't yet used it in
2013   e.g. wxDC.
2014
2015 Generic:
2016
2017 - GENERIC AND MSW-SPECIFIC CODE NOW TREATED AS TWO SEPARATE
2018   DISTRIBUTIONS. This change log will therefore now refer to
2019   the generic code only. See docs/msw/changes.txt for Windows-specific
2020   changes.
2021 - Readmes, change logs and installation files now go in
2022   platform-specific directories under docs, e.g. docs/msw,
2023   docs/gtk.
2024 - Added DECLARE_APP and IMPLEMENT_APP macros so wxApp object gets
2025   created dynamically, not as a global object.
2026 - Put wxColour into wx/msw/colour.h, src/msw/colour.cpp.
2027 - Changed names of some include/wx/generic headers to be
2028   consistent and to conform to gcc pragma conventions. Also
2029   changed choicesg.cpp to choicdgg.cpp.
2030 - Added gcc pragmas.
2031 - Added gtk inclusion in include/wx headers.
2032 - Added consistent file headings to source and headers.
2033 - Removed lang.cpp, lang.h and references to wxSTR_... variables;
2034   added a few references to wxTransString.
2035 - Added operator to wxTransString that converts automatically
2036   to wxString, so we can say e.g. wxMessageBox(wxTransString("Hello"), ...).
2037 - samples/internat now works (minimally).
2038 - Added wxMouseEvent::GetPosition and
2039   wxMouseEvent::GetLogicalPosition, both returning wxPoints.
2040 - Made wxSize and wxRect contain longs not ints.
2041 - Cured some memory leaks (thanks Vadim).
2042 - Tidied up OnIdle and introduced RequestMore/MoreRequested so
2043   will only keep processing OnIdle if it returns TRUE from
2044   MoreRequested.
2045
2046 Alpha 4, 31st January 1998
2047 --------------------------
2048
2049 All:
2050
2051 - Changed wxDC functions to take longs instead of floats. GetSize now takes
2052   integer pointers, plus a version that returns a wxSize.
2053 - const keyword added to various wxDC functions.
2054 - Under Windows, wxDC no longer has any knowledge of whether
2055   an associated window is scrolled or not. Instead, the device
2056   origin is set by wxScrolledWindow in wxScrolledWindow::PrepareDC.
2057 - wxScrolledWindow applications can optionally override the virtual OnDraw
2058   function instead of using the OnPaint event handler. The wxDC passed to
2059   OnDraw will be translated by PrepareDC to reflect scrolling.
2060   When drawing outside of OnDraw, must call PrepareDC explicitly.
2061 - wxToolBarBase/wxToolBarSimple similarly changed to allow for
2062   scrolling toolbars.
2063 - Integrated wxPostScriptDC patches for 1.xx by Chris Breeze,
2064   to help printing with multiple pages.
2065 - IPC classes given base classes (wxConnectionBase etc.) which
2066   define the API used by different implementations. DDE
2067   implementation updated to use these base classes.
2068 - wxHelpInstance now separated into wxHelpControllerBase (base
2069   for all implementations), wxWinHelpController (uses standard
2070   WinHelp), wxXLPHelpController (talks to wxHelp by DDE or
2071   TCP/IP). There will be others eventually, such as
2072   wxHTMLHelpController for Microsoft (and Netscape?) HTML Help.
2073 - Added Vadim Zeitlin's wxString class plus
2074   internationalization code (gettext simulation, wxLocale, etc.).
2075   New files from Vadim:
2076   include\wx\string.h
2077   include\wx\debug.h
2078   include\wx\file.h
2079   include\wx\log.h
2080   include\wx\intl.h
2081   src\common\string.cpp
2082   src\common\log.cpp
2083   src\common\intl.cpp
2084   src\common\file.cpp
2085   No longer use GNU wxString files.
2086 - Split off file-related functions into include\wx\filefn.h and
2087   src\common\filefn.cpp.
2088 - Borland C++ support (WIN32) for main library and
2089   samples, using makefile.b32 files.
2090 - Preparation done for allowing BC++ to compile wxWin as a DLL,
2091   including changes to defs.h.
2092 - wxIntPoint removed, wxPoint is now int, and wxRealPoint
2093   introduced.
2094 - Added wxShowEvent (generated when window is being shown or
2095   hidden).
2096 - Got minimal, docview, mdi samples working for 16-bit VC++ and
2097   cured 16-bit problem with wxTextCtrl (removed global memory
2098   trick).
2099 - Updated GnuWin32 makefiles, checked minimal, mdi, docview samples.
2100
2101 Alpha 3, September 1997
2102 -----------------------
2103
2104 All:
2105
2106 - wxListCtrl, wxTreeCtrl, wxImageList classes done.
2107 - Instigated new file hierarchy, split files and classes up more logically.
2108 - PrologIO and some other utils now put into core library.
2109 - Revamped print/preview classes, added wxPageSetupDialog.
2110 - Started documentation.
2111
2112 Alpha 2, 30th April 1997
2113 ------------------------
2114
2115 All:
2116
2117 - EVT_... macros now have at least one argument, for conformance
2118   with MetroWerks compiler.
2119 - Added ids to .wxr file format.
2120 - Got Dialog Editor compiled and running again but need
2121   to extend functionality to be in line with new controls.
2122   Added dialoged\test app to allow dynamic loading of .wxr files
2123   for testing purposes.
2124 - Rewrote wxBitmap to allow installable file type
2125   handlers.
2126 - Rewrote wxBitmapButton, wxStaticBitmap to not use Fafa.
2127 - Wrote most of wxTreeCtrl and sample (need wxImageList to implement it
2128   fully).
2129 - Added back wxRadioBox.
2130 - Tidied up wx_main.cpp, wxApp class, putting PenWin code in
2131   a separate file.
2132
2133 Alpha 1, 5th April 1997
2134 -----------------------
2135
2136 Generic:
2137
2138 At this point, the following has been achieved:
2139
2140 - A lot, but not all, of the code has been revamped for better
2141   naming conventions, protection of data members, and use of
2142   wxString instead of char *.
2143 - Obsolete functionality deleted (e.g. default wxPanel layout,
2144   old system event system) and code size reduced.
2145 - Class hierarchy changed (see design doc) - base classes such
2146   as wxbWindow now removed.
2147 - No longer includes windows.h in wxWin headers, by using stand-in
2148   Windows types where needed e.g. WXHWND.
2149 - PrologIO revised.
2150 - wxScrolledWindow, wxStatusBar and new MDI classes added.
2151   MDI is now achieved using separate classes, not window styles.
2152 - wxSystemSettings added, and made use of to reflect standard
2153   Windows settings.
2154 - SetButtonFont/SetLabelFont replaced by SetFont; font and colour
2155   settings mucho rationalised.
2156 - All windows are now subclassed with the same window proc to make
2157   event handling far more consistent. Old internal wxWnd and derived
2158   classes removed.
2159 - API for controls revised, in particular addition of
2160   wxValidator parameters and removal of labels for some controls.
2161 - 1 validator written: see examples/validate.
2162 - Event table system introduced (see most samples and
2163   wx_event.cpp/ProcessEvent, wx_event.h). wxEvtHandler
2164   made more flexible, with Push/PopEventHandler allowing a chain
2165   of event handlers.
2166 - wxRadioBox removed - will be added back soon.
2167 - Toolbar class hierarchy revised:
2168   wxToolBarBase
2169   wxToolBarSimple (= old wxToolBar)
2170   wxToolBar95 (= old wxButtonBar under Win95)
2171   wxToolBarMSW (= old wxButtonBar under WIN16/WIN32)
2172 - Constraint system debugged somewhat (sizers now work properly).
2173 - wxFileDialog, wxDirDialog added; other common dialogs now
2174   have class equivalents. Generic colour and font dialogs
2175   rewritten to not need obsolete panel layout.
2176 - .wxr resource system partially reinstated, though needs
2177   an integer ID for controls. Hopefully the resource system
2178   will be replaced by something better and more efficient
2179   in the future.
2180 - Device contexts no longer stored with window and accessed
2181   with GetDC - use wxClientDC, wxPaintDC, wxWindowDC stack
2182   variables instead.
2183 - wxSlider uses trackbar class under Win95, and wxSL_LABELS flag
2184   determines whether labels are shown. Other Win95-specific flags
2185   introduced, e.g. for showing ticks.
2186 - Styles introduced for dealing with 3D effects per window, for
2187   any window: all Win95 3D effects supported, plus transparent windows.
2188 - Major change to allow 3D effect support without CTL3D, under
2189   Win95.
2190 - Bitmap versions of button and checkbox separated out into new
2191   classes, but unimplemented as yet because I intend to remove
2192   the need for Fafa - it apparently causes GPFs in Win95 OSR 2.
2193 - utils/wxprop classes working (except maybe wxPropertyFormView)
2194   in preparation for use in Dialog Editor.
2195 - GNU-WIN32 compilation verified (a month or so ago).
