   5 2.5.4
   6 -----
   7
   8 All:
   9
  10 - wxEvent and derived classes don't have public members any more, you must
  11   use accessors methods now (Mart Raudsepp)
  12 - new classes for reading and writing ZIP files (M.J.Wetherell)
  13 - large files support for wxFFile (M.J.Wetherell)
  14 - classes in the manual are now cross-referenced (Zbigniew Zagórski)
  15 - Norwegian (Bokmål) translation added (Hans F. Nordhaug)
  16 - wxDynamicLibrary::HasSymbol() added
  17 - added wxEXEC_NODISABLE flag to be used with wxExecute(wxEXEC_SYNC)
  18 - added wxTextInputStream::operator>>(wchar_t) for compilers which support this
  19 - added wxURI, a class for dealing with Uniform Resource Identifiers
  20 - changed wxURL to inherit from wxURI and provide assignment and comparison
  21 - implemented wxConvUTF7 (modified patch from Fredrik Roubert)
  22 - added versions of MB2WC and WC2MB for wxMBConv that for embedded null chars
  23 - Unicode support in wxODBC is now fully implemented
  24 - A new data type specific to wxWidgets called SQL_C_WXCHAR has been introduced.
  25   SQL_C_WXCHAR should be used rather than SQL_C_CHAR to ensure transparent
  26   behavior between Unicode and non-unicode builds
  27 - BLOB example added to samples/db (thanks to Casey ODonnell)
  28 - use wxStream::GetLength() instead of deprecated GetSize()
  29 - wxGetOsDescription() is now more precise (Olly Betts)
  30 - XRC supports system fonts and colours (Ray Gilbert)
  31 - Added flags argument to wxKill/wxProcess::Kill to kill child processes.
  32 - Added wxPrintFactory classes so that it is possible to add a new
  33   print system backend at run-time. This was required by the new GNOME
  34   printing stuff in the GTK port.
  35 - Deprecated print setup dialog.
  36 - Added support to the wxODBC classes for Firebird 1.5 database
  37 - The samples\db sample program now includes an optional example of using a BLOB
  38   datatype (if BLOB support is enabled and supported by the database)
  39 - added wxDynamicLibrary::ListLoaded()
  40 - wxGetPowerType() and wxGetBatteryState() addition
  41 - wxSystemSettings::GetSystem*() members deprecated and replaced with
  42   wxSystemSettings::Get*()
  43 - wxWindowBase::DoGetBestSize now includes the difference (if any) between
  44   the client size and total size of the window.  Code that sets the
  45   client size using the best size, or that added extra space to sizers
  46   to compensate for this bug may need to be changed.
  47 - Changed calculation of scrolling area to not clip away some bits
  48   due to a rounding error.
  49 - Changed GetVirtualSize() to return client size by default until
  50   SetVirtualSize() gets called. From then on it will only return that.
  51 - Various changes to how wxListCtrl and wxTreeCtrl react to right
  52   mouse clicks and left mouse click for starting a drag operation.
  53 - "Alt" key (VK_MENU) now results in WXK_ALT keyboard event, not WXK_MENU
  54 - wxFFile::ReadAll() now takes an optional wxMBConv parameter
  55 - wxCommandProcessor::MarkAsSaved() and IsDirty() added (Angela Wrobel)
  56 - added wxStackWalker and related classes (Win32 and some Unix versions only)
  57
  58
  59 All (GUI):
  60
  61 - added wxMediaCtrl
  62 - added wxDatePickerCtrl
  63 - wxHtmlWindow now supports background images given in <body> tag
  64 - wxSplitterWindow now supports gravity parameter (Zbigniew Zagórski)
  65 - recursive wxSizer::GetItem returns item of given window, sizer or nth index
  66 - wxLayoutConstraints now use best size, not current size, for AsIs() condition
  67 - wxSizer::Add/Insert etc. now returns pointer to wxSizerItem just added and this
  68   item remembers its wxRect area (Brian A. Vanderburg II)
  69 - wxBookCtrl renamed to wxBookCtrlBase, wxBookCtrl is reserved for most native
  70   book control (for now wxChoicebook for MSSmartphone, wxNotebook for others).
  71   Necessary event macros, types and styles mapped accordingly.
  72 - new wxBrush::IsHatch() checking for brush type replaces IS_HATCH macro
  73 - wxProgressDialog accepts smooth gauge again (wxPD_SMOOTH style)
  74 - wxProgressDialog new style: wxPD_CAN_SKIP which provides skipping some parts
  75   of the progress (with new "Skip" button in dialog)
  76 - wxGenericListCtrl::SetItemState(-1) now changes the state of all items as
  77   in wxMSW version (Gunnar Roth)
  78 - added wxImage::InitAlpha()
  79
  80 Unix:
  81
  82 - wxPuts() now correctly outputs trailing new line in Unicode build
  83
  84 wxGTK:
  85
  86 - Added printing support by way of using libgnomeprint. The library
  87   now checks at runtime, if the library is installed and will use it
  88   if it is. Otherwise, it will fall back to the old PostScript printing
  89   code, from which the Pango drawing code was removed.
  90 - Implemented/improved wxDC::DrawRotatedText()
  91 - fixed wxFileDialog::SetWildcard()
  92 - native file dialog is now used if available (Zbigniew Zagorski)
  93 - implemented wxTextCtrl::Freeze() and Thaw(). The GtkTextBuffer
  94   is not a valid one during frozen state. Get a pointer to it right
  95   after wxTextCtrl creation if you really need to. (Mart Raudsepp)
  96 - Changed calls to GTK+ 2.4.x functions so that the code checks at
  97   runtime, which library version is installed so that these functions
  98   are only called with GTK+ 2.4.x installed and should yield linker
  99   errors otherwise.
 100 - wxTextCtrl text insertion efficiency fixed. (Mart Raudsepp)
 101 - Added wxRawBitmap support
 102 - Corrected Input method handler code (for Chinese etc.) and its
 103   interaction with wxWidgets' events.
 104 - wxTE_AUTO_URL implemention for wxGTK2 multiline wxTextCtrls (Mart Raudsepp)
 105
 106 wxMac:
 107
 108 - Vertical sliders oriented consistent with MSW/GTK (0 at top) (Kevin Hock)
 109 - wxDynamicLibrary::GetDllExt() now returns ".bundle", not ".dylib"

 114
 115 - fixed enhanced metafiles loading from files (Andreas Goebel)
 116 - wxRadioButtons no longer have to be consecutive in a group
 117 - fixed spurious selection of combobox text during resize

 119 - added wxRegKey::Export(file)
 120
 121 wxWinCE:
 122 - Added support for MS Handheld PC 2000. This was done before 2.5.4,
 123   but not mentioned anywhere.
 124 - Added (preliminary) support for sockets
 125
 126 wxUniv:
 127
 128 - wxBU_... button align flags support

 132
 133 wxPalmOS:
 134
 135 - William Osborne has won and new port was born
 136   (see: "wxPalmOS porting challenge")
 137 - polishing of the port (unnecessary 2.4 API compatibility, removed
 138   all wxMSW specific code which was base for the new port)
 139 - enumeration of available volumes
 140 - native wxPrefConfig around Preferences database

 289 2.5.2
 290 -----
 291
 292 All:
 293
 294 - Hindi translation added (Dhananjaya Sharma)
 295 - Brazilian Portuguese translation added (E. A. Tacao)
 296 - wxDynamicCast() now uses static_cast<wxObject *> internally and so using it
 297   with anything not deriving from wxObject will fail at compile time (instead
 298   of run-time) now
 299 - when wxUSE_STL == 1 and STL provides quasi-standard hash_map/hash_set,
 300   wxHashMap/wxHashSet are just typedefs for them. This makes impossible
 301   to forward declare these classes.
 302
 303 All (GUI):
 304
 305 - wxHtmlWindow now delays image scaling until rendering,
 306   resulting in much better display of scaled images
 307 - Added UpdateSize to wxSplitterWindow to allow layout while hidden
 308 - implemented Freeze/Thaw() for wxGenericTreeCtrl (Kevin Hock)
 309 - support for KOI8-U encoding added (Yuriy Tkachenko)
 310 - The old wxADJUST_MINSIZE behaviour is now the default behaviour for
 311   sizer items that are windows.  This means that GetAdjustedBestSize
 312   will now be called by default to determine the minimum size that a
 313   window in a sizer should have.  If you want to still use the initial
 314   size (and not the BestSize) then use the wxFIXED_MINSIZE flag.  When
 315   windows are added to a sizer their initial size is made the window's
 316   min size using SetSizeHints, and calls to wxSizer::SetItemMinSize
 317   are also forwarded to SetSizeHints for window items.
 318 - added wxRegEx::GetMatchCount()
 319 - it is now possible to display images in wxHtmlListBox
 320
 321 wxMSW:
 322
 323 - wxWindow::Freeze()/Thaw() can now be nested
 324 - Added wxSP_NO_XP_THEME style to wxSplitterWindow to switch off
 325   XP theming (some applications look bad without 3D borders)
 326 - wxMenuBar::GetLabelTop() doesn't include '&'s in the label any more
 327 - wxRegConf couldn't read global settings without admin privileges and didn't
 328   even try to do it by default -- now it does
 329 - wxTaskBarIcon must be explicitly destroyed now, otherwise the application
 330   won't exit even though there are no top level windows
 331 - wxFileName::GetModificationTime() works with opened files too now
 332 - wxDC::GetClippingBox() now works even for clipping regions created by Windows
 333 - fixed wxFileDataObject in Unicode build (Alex D)
 334 - subindented paragraphs support (Tim Kosse)
 335
 336 wxGTK:
 337
 338 - added support for wxTE_RIGHT and wxTE_CENTRE styles under GTK2 (Mart Raudsepp)
 339
 340 wxMotif:
 341
 342 - removed wxMenuItem::DeleteSubMenu()
 343 - wxButtons use Motif default size, which is smaller than it used to be
 344   and closer to wxMSW/wxGTK look. This can be disabled by setting
 345   motif.largebuttons system option to 1 (see wxSystemOptions).
 346
 347 wxUniv/X11:
 348
 349 - implemented DrawRoundedRectangle() (clawghoul)
 350
 351 wxHTML:
 352
 353 - improved tables and lists layout algorithms (Tim Kosse)
 354 - <div> handling fix (Xavier Nodet)
 355
 356 Unix:
 357
 358 - fixed priorities of mailcap entries (David Hart)
 359 - added "wx-config --libs=std,<extra>" syntax (i.e. support for "std")
 360
 361 wxODBC:
 362
 363 - Full Unicode support is now available
 364 - BLOB support is working
 365
 366

 497 -----
 498
 499 All:
 500
 501 - It is now possible to build several smaller libraries instead of single

 527   std::vector, wxList from std::list. In addition wxHashTable will be
 528   implemented in terms of wxHashMap.
 529 - Added wxList::compatibility_iterator. Can be used like wxNode* (except
 530   it can't be delete()d). It permits writing code which will work
 531   both with wxUSE_STL==1 and wxUSE_STL==0.
 532
 533 wxBase:
 534
 535 - added Watcom makefiles

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

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

 676   documentation for a detailed explanation
 677 - implemented wxWakeUpIdle
 678 - for Motif 2.0, used the native combobox widget instead of the GPL'd

 700 OLD CHANGES
 701 ===========
 702
 703 INCOMPATIBLE CHANGES SINCE 2.2.x
 704 ================================
 705
 706     Please take a few minutes to read the following list, especially
 707     paying attention to the most important changes which are marked
 708     with '!' in the first column.
 709
 710     Also please note that you should ensure that WXWIN_COMPATIBILITY_2_2
 711     is defined to 1 if you wish to retain maximal compatibility with 2.2
 712     series -- however you are also strongly encouraged to try to compile
 713     your code without this define as it won't be default any longer in
 714     2.6 release.
 715
 716     NB: if you want to build your program with different major versions
 717         of wxWidgets you will probably find the wxCHECK_VERSION() macro
 718         (see the documentation) useful.
 719
 720
 721 wxBase:
 722
 723 ! wxArray<T>::Remove(size_t) has been removed to fix compilation problems
 724   under 64 bit architectures, please replace it with RemoveAt() in your
 725   code.
 726
 727 ! wxArray<T> macros have been changed to fix runtime problems under 64 bit
 728   architectures and as a side effect of this WX_DEFINE_ARRAY() can only be
 729   used now for the pointer types, WX_DEFINE_ARRAY_INT should be used for the
 730   arrays containing non-pointers.
 731
 732 - wxObject::CopyObject() and Clone() methods were removed because they
 733   simply don't make sense for all objects
 734
 735 - wxEvent now has a pure virtual Clone() method which must be implemented
 736   by all derived classes, if you have user-defined event classes please
 737   add "wxEvent *Clone() const { return new MyEvent(*this); }" line to them
 738
 739 - small change to wxStopWatch::Pause() semantics, please see the documentation
 740
 741 - unlikely but possible incompatibility: the definition of TRUE has changed
 742   from "1" to "(bool)1" (and the same thing for FALSE), so the code which
 743   could be erroneously compiled previously such as doing "return FALSE" from
 744   a function returning a pointer would stop compiling now (but this change
 745   is not supposed to have any effects on valid code)
 746
 747 - another minor change: wxApp::OnAssert() has a new "cond" argument, you
 748   must modify YourApp::OnAssert() signature if you were using it to override
 749   the default assert handling.
 750
 751 All (GUI):
 752
 753 ! the event type constants are not constants any more but are dynamically
 754   allocated during run-time which means that they can't be used as case labels
 755   in the switch()es, you must rewrite them to use if()s instead
 756
 757   You may also define WXWIN_COMPATIBILITY_EVENT_TYPES to get the old behaviour
 758   but this is strongly discouraged, please consider changing your code
 759   instead!
 760
 761 ! wxDialog does not derive from wxPanel any longer - if you were using it in
 762   your code, please update it. The quick fix for the most cases is to replace
 763   the occurrences of wxPanel with wxWindow.
 764
 765 ! if you handle (and don't skip) EVT_KEY_DOWN, the EVT_CHAR event is not
 766   generated at all, so you must call event.Skip() in your OnKeyDown() if
 767   you want to get OnChar() as well
 768
 769 - in general, the key events sent for the various non ASCII key combinations
 770   have been changed to make them consistent over all supported platforms,
 771   please see the wxKeyEvent documentation for details
 772
 773 - wxYES_NO is now wxYES | wxNO and the manifest values of both wxYES and wxNO
 774   have changed (to fix some unfortunate clashes), please check your code to
 775   ensure that no tests for wxYES or wxNO are broken: for example, the following
 776   will *NOT* work any longer:
 777
 778         if ( flags & wxYES_NO )
 779                 ... do something ...
 780         if ( flags & wxYES )
 781                 ... do something else ...
 782
 783 - static wxWizard::Create() doesn't exist any more, the wizards are created
 784   in the same way as all the other wxWindow objects, i.e. by directly using
 785   the ctor
 786
 787 - wxGLCanvas now derives directly from wxWindow, not wxScrolledWindow
 788
 789 - wxGridCellAttrProvider class API changed, you will need to update your code
 790   if you derived any classes from it
 791
 792 - wxImage::ComputeHistogram()'s signature changed to
 793   unsigned long ComputeHistogram(wxImageHistogram&) const
 794
 795 - wxEvtHandler cannot be copied/assigned any longer - this never worked but
 796   now it results in compile-time error instead of run-time crashes
 797
 798 - WXK_NUMLOCK and WXK_SCROLL keys no longer result in EVT_CHAR() events,
 799   they only generate EVT_KEY_DOWN/UP() ones
 800
 801 - the dialogs use wxApp::GetTopWindow() as the parent implicitly if the
 802   parent specified is NULL, use wxDIALOG_NO_PARENT style to prevent this
 803   from happening
 804
 805 - several obsolete synonyms are only retained in WXWIN_COMPATIBILITY_2_2 mode:
 806   for example, use wxScrolledWindow::GetViewStart() now instead of ViewStart()
 807   and GetCount() instead of Number() in many classes
 808
 809 - wxCmdLineParser does not use wxLog to output messages anymore.
 810   to obtain the previous behaviour, add
 811   wxMessageOutput::Set(new wxMessageOutputLog); to your program
 812   (you will need to #include <wx/msgout.h>)
 813
 814 wxMSW:
 815
 816 ! build system changed: setup.h is not a static file in include/wx any more
 817   but is created as part of the build process under lib/<toolkit>/wx
 818   where <toolkit> is of the form (msw|univ)[dll][u][d]. You'll need to update
 819   the include path in your make/project files appropriately. Furthermore,
 820   xpm.lib is no longer used by wxMSW, it was superseded by the wxXPMDecoder
 821   class. You'll need to remove all references to xpm.lib from your
 822   make/project files. Finally, the library names have changed as well and now
 823   use the following consistent naming convention: wxmsw[ver][u][d].(lib|dll)
 824   where 'u' appears for Unicode version, 'd' -- for the debug one and version
 825   is only present for the DLLs builds.
 826
 827 - child frames appear in the taskbar by default now, use wxFRAME_NO_TASKBAR
 828   style to avoid it
 829
 830 - all overloads of wxDC::SetClippingRegion() combine the given region with the
 831   previously selected one instead of replacing it
 832
 833 - wxGetHomeDir() uses HOME environment variable and if it is set will not
 834   return the programs directory any longer but its value (this function has
 835   never been meant to return the programs directory anyhow)
 836
 837 - wxHTML apps don't need to include wx/html/msw/wxhtml.rc in resources file
 838   anymore. The file was removed from wxMSW
 839
 840
 841 Unix ports:
 842
 843 ! You should use `wx-config --cxxflags` in your makefiles instead of
 844   `wx-config --cflags` for compiling C++ files. CXXFLAGS contains CFLAGS
 845   and the compiler flags for C++ files only, CFLAGS should still be used
 846   to compile pure C files.
 847
 848
 849 wxThread and related classes:
 850
 851 - The thread-related classes have been heavily changed since 2.2.x versions
 852   as the old code had many serious problems. This could have resulted in
 853   semantical changes other than those mentioned here, please review use of
 854   wxThread, wxMutex and wxCondition classes in your code.
 855
 856 ! wxCondition now *must* be used with a mutex, please read the (updated) class
 857   documentation for details and revise your code accordingly: this change was
 858   unfortunately needed as it was impossible to ensure the correct behaviour
 859   (i.e. absence of race conditions) using the old API.
 860
 861 - wxMutex is not recursive any more in POSIX implementation (it hasn't been
 862   recursive in 2.2.x but was in 2.3.1 and 2.3.2), please refer to the class
 863   documentation for the discussion of the recursive mutexes.
 864
 865 - wxMutex::IsLocked() doesn't exist any more and should have never existed:
 866   this is was unique example of a thread-unsafe-by-design method.
 867

1513
1514 - wxExecute improved.
1515
1516 wxMSW:
1517
1518 - Fixed wxWindow::IsShown (::IsWindowVisible doesn't behave as
1519   expected).
1520 - Changed VC++ makefiles (.vc) so that it's possible to have
1521   debug/release/DLL versions of the library available simultaneously,
1522   with names wx.lib, wx_d.lib, wx200.lib(dll), wx200_d.lib(dll).
1523 - Added BC++ 5 IDE files and instructions.
1524 - Fixed wxChoice, wxComboBox constructor bugs (m_noStrings initialisation).

1536 - wxHelpController API changed: SetBrowser becomes SetViewer,
1537   DisplaySection works for WinHelp, help sample compiles under Windows
1538   (though doesn't display help yet).
1539
1540 Beta 4, February 12th 1999
1541 --------------------------
1542
1543 wxGTK:
1544
1545 - Miscellaneous fixes.
1546
1547 wxMSW:
1548
1549 - Makefiles for more compilers and samples; Cygwin makefiles
1550   rationalised.
1551 - Added VC++ project file for compiling wxWidgets as DLL.
1552
1553 wxMotif:

1555 - Added OnEraseBackground invocation.
1556 - Added wxRETAINED implementation for wxScrolledWindow.
1557 - Cured scrolling display problem by adding XmUpdateDisplay.
1558 - Tried to make lex-ing in the makefile more generic (command line
1559   syntax should apply to both lex and flex).
1560 - Changed file selector colours for consistency (except for buttons:
1561   crashes for some reason).
1562 - Fixed wxMotif version of wxImage::ConvertToBitmap (used new instead
1563   of malloc, which causes memory problems).
1564
1565 General:
1566
1567 - Further doc improvements.
1568 - wxGenericValidator added.
1569 - Added wxImageModule to image.cpp, so adds/cleans up standard handlers
1570   automatically.
1571
1572 Beta 3, January 31st 1999
1573 -------------------------
1574
1575 wxGTK:

1615 - Cured wxScreenDC origin problem so e.g. sash window sash is drawn at
1616   the right place.
1617 - Cured some widget table clashes.
1618 - Added thread support (Robert).
1619 - wxPoem sample now works.
1620
1621 General:
1622
1623 - Rearranged documentation a bit.
1624 - Sash window uses area of first frame/dialog to paint over when drawing
1625   the dragged sash, not just the sash window itself (it clipped to the right
1626   or below).
1627 - Made resource sample use the correct Cancel button id.
1628 - Moved wxProp to main library (generic directory), created proplist
1629   sample.
1630 - Added bombs and fractal samples.
1631
1632 Beta 1, December 24th 1998
1633 --------------------------
1634
1635 wxGTK:
1636
1637 - Various
1638
1639 wxMSW, wxMotif: not in sync with this release.
1640
1641
1642 Alpha 18, December 29th 1998
1643 ----------------------------
1644
1645 wxMSW:
1646
1647 - Win16 support working again (VC++ 1.5)
1648 - Win16 now uses generic wxNotebook, wxListCtrl,
1649   wxTreeCtrl -- more or less working now, although
1650   a little work on wxNotebook is still needed.
1651   Under 16-bit Windows, get assertion when you click
1652   on a tab.
1653 - Wrote 16-bit BC++ makefiles: samples don't yet link.
1654 - Added CodeWarrior support to distribution courtesy
1655   of Stefan Csomor.
1656
1657 wxMotif:
1658
1659 - Cured scrolling problem: scrollbars now show/hide themselves
1660   without (permanently) resizing the window.
1661 - Removed some commented-out lines in wxScrolledWindow::AdjustScrollbars
1662   that disabled scrollbar paging.
1663 - Set background colour of drawing area in wxWindow, so e.g. wxListCtrl
1664   colours correctly.
1665 - Removed major bug whereby dialogs were unmanaged automatically
1666   when any button was pressed.
1667 - Fixed colours of wxWindow scrollbars, made list and text controls
1668   have a white background.
1669 - Fixed dialog colour setting.
1670 - Added settable fonts and colours for wxMenu/wxMenuBar. Now
1671   they have sensible colours by default.
1672 - Fixed a bug in wxStaticBox.
1673 - Cured wxTreeCtrl bug: now works pretty well!
1674 - Debugged DrawEllipticArc (a ! in the wrong place).
1675 - Added SetClippingRegion( const wxRegion& region ).
1676 - Added wxPoint, wxSize, wxRect versions of SetSize etc.
1677
1678 Alpha 17, November 22nd 1998
1679 ----------------------------
1680
1681 wxMSW:
1682
1683 - More documentation updates, especially for
1684   wxLayoutWindow classes and debugging facilities.
1685 - Changed wxDebugContext to use wxDebugLog instead
1686   of wxTrace.
1687 - Now supports VC++ 6.0, and hopefully BC++ 5.0.
1688   However, DLL support may be broken for BC++ since
1689   VC++ 6 required changing of WXDLLEXPORT keyword
1690   position.
1691 - Numerous miscellaneous changes.
1692
1693 wxMotif:
1694
1695 - Reimplemented MDI using wxNotebook instead of the MDI widgets, which
1696   were too buggy (probably not design for dynamic addition/removal of
1697   child frames).
1698 - Some improvements to the wxNotebook implementation.
1699 - wxToolBar now uses a bulletin board instead of a form, in an attempt
1700   to make it possible to add ordinary wxControls to a toolbar.
1701 - Cured problem with not being able to use global memory operators,
1702   by defining two more global operators, so that the delete will match
1703   the debugging implementation.
1704 - Added wxUSE_DEBUG_NEW_ALWAYS so we can distinguish between using
1705   global memory operators (usually OK) and #defining new to be
1706   WXDEBUG_NEW (sometimes it might not be OK).
1707 - Added time.cpp to makefile; set wxUSE_DATETIME to 1.
1708 - Added a parent-existence check to popup menu code to make it not crash.
1709 - Added some optimization in wxWindow::SetSize to produce less flicker.
1710   It remains to be seen whether this produces any resize bugs.
1711
1712 It's a long time since I updated this file. Previously done:
1713
1714 - wxFrame, wxDialog done.
1715 - wxScrolledWindow done (but backing pixmap not used at present).
1716 - wxBitmap done though could be tidied it up at some point.
1717 - Most basic controls are there, if not rigorously tested.
1718 - Some MDI support (menus appear on child frames at present).
1719 - wxNotebook almost done.
1720 - wxToolBar done (horizontal only, which would be easy to extend
1721   to vertical toolbars).
1722
1723 More recently:
1724
1725 - Colour and font changing done (question mark over what happens
1726   to scrollbars).
1727 - Accelerators done (for menu items and buttons). Also event loop
1728   tidied up in wxApp so that events are filtered through ProcessXEvent.
1729 - wxWindow::GetUpdateRegion should now work.
1730
1731 Alpha 16, September 8th 1998
1732 ----------------------------
1733
1734 wxMSW:
1735
1736 - Added wxSashWindow, wxSashLayoutWindow classes, and sashtest
1737   sample.
1738 - Guilhem's socket classes added, plus wxsocket sample.
1739 - A few more makefiles added.
1740 - GnuWin32/BC++ compatibility mods.
1741 - Further doc updates.
1742 - wxProp updates for correct working with wxGTK.
1743
1744 wxMotif:
1745
1746 - First start at Motif port.
1747 - Made makefiles for wxMotif source directory and minimal sample.
1748 - First go at wxApp, wxWindow, wxDialog, wxPen, wxBrush, wxFont,
1749   wxColour, wxButton, wxCheckBox, wxTextCtrl, wxStaticText,
1750   wxMenu, wxMenuItem, wxMenuBar
1751
1752 Alpha 15, August 31st 1998
1753 --------------------------
1754
1755 wxMSW:
1756
1757 - wxBitmap debugged.
1758 - wxDC::GetDepth added.
1759 - Contribution added whereby wxBitmap will be
1760   converted to DC depth if they don't match.
1761 - wxConfig API improved, documentation updated.
1762 - Printing classes name conventions cleaned up.
1763 - wxUpdateUIEvent now derives from wxCommandEvent
1764   so event can travel up the window hierarchy.
1765
1766 Alpha 14, July 31st 1998
1767 ------------------------
1768
1769 wxMSW:
1770
1771 - Toolbar API has been simplified, and now
1772   wxFrame::GetClientArea returns the available client
1773   area when toolbar, status bar etc. have been accounted for.
1774   wxFrame::CreateToolBar added in line with CreateStatusBar.
1775 - Documentation updates, incl. for wxToolBar.
1776 - New wxAcceleratorTable class plus wxFrame::SetAcceleratorTable.
1777 - Various additions from other folk, e.g. streams, wxConfig
1778   changes, wxNotebook.
1779 - Added wxDocMDIParentFrame, wxDocMDIChildFrame for doc/view.
1780
1781 Alpha 13, July 8th 1998
1782 -----------------------
1783
1784 wxMSW:
1785
1786 - Implemented wxPoint as identical to POINT on Windows, and
1787   altered wxDC wxPoint functions to use wxPoint directly in
1788   Windows functions, for efficiency.
1789 - Cured wxASSERT bug in wxStatusBar95.
1790 - #ifdefed out some bits in oleutils.cpp for compilers that
1791   don't support it.
1792 - Added some operators to wxPoint, wxSize.
1793 - Added inline wxDC functions using wxPoint, wxSize, wxRect.
1794
1795 Alpha 12, July 7th 1998
1796 -----------------------
1797
1798 wxMSW:
1799
1800 - Added wxApp::GetComCtl32Version, and wxTB_FLAT style, so can
1801   have flat toolbars on Win98 or Win95 with IE >= 3 installed.
1802
1803 Alpha 11, July 3rd 1998
1804 -----------------------
1805
1806 wxMSW:
1807
1808 - Added thread.h, thread.cpp.
1809 - Changed Enabled, Checked to IsEnabled, IsChecked in wxMenu,
1810   wxMenuBar.
1811 - Changed wxMenuItem::SetBackColor to SetBackgroundColour,
1812   SetTextColor to SetTextColour, and added or made public several
1813   wxMenuItem accessors.
1814 - Added two overloads to wxRegion::Contains. Added
1815   wxRegion::IsEmpty for a more consistent naming convention.
1816 - Added Vadim's wxDataObject and wxDropSource.
1817 - ENTER/LEAVE events now work.
1818 - Cured wxMemoryDC bug where the DC wasn't being deleted.
1819 - Cured wxGauge SetSize major bugginess.
1820 - Cured problem where if a GDI object was created on the stack,
1821   then went out of scope, then another object was selected into
1822   the DC, GDI objects would leak. This is because the assignment
1823   to e.g. wxDC::m_pen would delete the GDI object without it first
1824   being selected out of the DC. Cured by selecting the old DC object
1825   first, then doing the assignment.
1826 - Split up wxGaugeMSW, wxGauge95, wxSliderMSW, wxSlider95
1827 - Various other bug fixes and additions.
1828
1829 Generic:
1830
1831 - Major work on Dialog Editor (still plenty to go).
1832 - Expanded documentation a bit more.
1833
1834 Alpha 10, May 7th 1998
1835 ----------------------
1836
1837 wxMSW:
1838
1839 - Added desiredWidth, desiredHeight parameters to wxBitmapHandler
1840   and wxIcon functions so that you can specify what size of
1841   icon should be loaded. Probably will remain a Windows-specific thing.
1842 - wxStatusBar95 now works for MDI frames.
1843 - Toolbars in MDI frames now behave normally. They still
1844   require application-supplied positioning code though.
1845 - Changed installation instructions, makefiles and batch files
1846   for compiling with Gnu-Win32/Mingw32/EGCS. Also timercmn.cpp
1847   change to support Mingw32/EGCS. Bison now used by default.
1848
1849 Alpha 9, April 27th 1998
1850 ------------------------
1851
1852 wxMSW:
1853
1854 - Cured bug in wxStatusBar95 that caused a crash if multiple
1855   fields were used.
1856 - Added Gnu-Win32 b19/Mingw32 support by changing resource
1857   compilation and pragmas.
1858 - Cured wxMenu bug introduced in alpha 8 - didn't respond to
1859   commands because VZ changed the id setting in wxMenu::MSWCommand.
1860
1861 Generic:
1862
1863 - Corrected some bugs, such as the wxModule compilation problem.
1864 - Added Gnu-Win32 b19/Mingw32 support by changing resource
1865   compilation and pragmas.
1866 - Changed SIZEOF to WXSIZEOF.
1867
1868 Alpha 8, April 17th 1998
1869 ------------------------
1870
1871 wxMSW:
1872
1873 - Added IsNull to wxGDIObject to check if the ref data is present or not.
1874 - Added PNG handler and sample - doesn't work for 16-bit PNGs for
1875   some reason :-(
1876 - Added wxJoystick class and event handling, and simple demo.
1877 - Added simple wxWave class. Needs Stop() function.
1878 - Added wxModule (module.h/module.cpp) to allow definition
1879   of modules to be initialized and cleaned up on wxWidgets
1880   startup/exit.
1881 - Start of Mingw32 compatibility (see minimal and dialogs samples
1882   makefile.m95 files, and install.txt).
1883 - Note: Windows printing has stopped working... will investigate.
1884 VADIM'S CHANGES:
1885 - Updated wxString: bug fixes, added wxArrayString, some
1886   compatibility functions.
1887 - Updated log.h/cpp, added wxApp::CreateLogTarget.
1888 - file.h: new wxTempFile class.
1889 - defs.h: added wxSB_SIZE_GRIP for wxStatusBar95
1890 - statbr95: wxStatusBar95 control.
1891 - registry.h/cpp: wxRegKey class for Win95 registry.
1892 - listbox.cpp: corrected some bugs with owner-drawn listboxes.
1893 - wxConfig and wxFileConfig classes.
1894
1895 Generic:
1896
1897 - Added src/other/png, src/other/zlib directories.
1898 - Added samples/png.
1899 - IMPORTANT: Changed 'no id' number from 0 to -1, in wxEVT_ macros.
1900   Porters, please check particularly your wxTreeCtrl and wxListCtrl
1901   header files.
1902 - Added modules.h/cpp, config.cpp, fileconf.cpp, textfile.cpp/h.
1903
1904 Alpha 7, March 30th 1998
1905 ------------------------
1906
1907 wxMSW:
1908
1909 - Added tab classes, tab sample.
1910 - Now can return FALSE from OnInit and windows will be
1911   cleaned up properly before exit.
1912 - Improved border handling so panels don't get borders
1913   automatically.
1914 - Debugged MDI activation from Window menu.
1915 - Changes to memory debug handling, including checking for
1916   memory leaks on application exit - but see issues.txt for
1917   unresolved issues.
1918 - Added wxTaskBarIcon (taskbar.cpp/h, plus samples/taskbar)
1919   to allow maintenance of an icon in the Windows 95 taskbar
1920   tray area.
1921 - Got MFC sample working (MFC and wxWidgets in the same
1922   application), partly by tweaking ntwxwin.mak settings.
1923 - Got DLL compilation working again (VC++).
1924 - Changed wxProp/Dialog Editor filenames.
1925
1926 Generic:
1927
1928 - Added tab classes, tab sample.
1929 - Revised memory.cpp, memory.h slightly; memory.h now #defines
1930   new to WXDEBUG_NEW in DEBUG mode. Windows implementation app.cpp
1931   now checks for leaks on exit. Added memcheck sample.
1932   See src/msw/issues.txt for more details.
1933 - resource.h, resource.cpp changed to make wxDefaultResourceTable
1934   a pointer. Now initialize resource system with
1935   wxInitializeResourceSystem and wxCleanUpResourceSystem, to
1936   allow better control of memory.
1937 - wxString now derives from wxObject, to enable memory leak
1938   checking.
1939 - Added some #include fixes in various files, plus changed
1940   float to long in wxToolBar files.
1941
1942 Alpha 6, March 10th 1998
1943 ------------------------
1944
1945 wxMSW:
1946
1947 - Found stack error bug - stopped unwanted OnIdle recursion.
1948 - Removed bug in wxTreeCtrl::InsertItem I added in alpha 5.
1949 - Changed exit behaviour in wxApp/wxFrame/wxDialog. Now will
1950   check if the number of top-level windows is zero before
1951   exiting. Also, wxApp::GetTopWindow will return either
1952   m_topWindow or the first member of wxTopLevelWindows, so you
1953   don't have to call wxApp::SetTopWindow.
1954 - Added dynarray.h/dynarray.cpp (from Vadim).
1955 - Added first cut at OLE drag and drop (from Vadim). dnd sample
1956   added. Drop target only at this stage. See src/msw/ole/*.cpp,
1957   wx/include/msw/ole/*.h. WIN32 only because of UUID usage.
1958   Doesn't work with GnuWin32 - no appropriate headers e.g. for
1959   IUnknown.
1960   Doesn't work with BC++ either - crashes on program startup.
1961 - Added Vadim's owner-draw modifications - will probably remain
1962   Windows-only. This enhances wxMenu, wxListBox. See ownerdrw sample.
1963 - Added wxLB_OWNERDRAW for owner-draw listboxes.
1964 - Vadim's wxCheckListBox derives from wxListBox. See checklst sample.
1965   Doesn't entirely work for WIN16.
1966 - Vadim has added wxMenuItem as a separate file menuitem.cpp. It
1967   can also be used as an argument to wxMenu::Append, not just for
1968   internal implementation.
1969 - Some #ifdefs done for MINGW32 compilation (just alter OPTIONS
1970   in makeg95.env, together with mingw32.bat). However, resource
1971   binding is not working yet so most apps with dialogs crash.
1972
1973 Generic:
1974
1975 - Added Vadim's dynarray.h, dynarray.cpp.
1976 - Added Vadim's menuitem.cpp.
1977 - Added Windows-specific wxCheckListBox,
1978   owner-draw wxListBox, and drag-and-drop
1979   (see docs/msw/changes.txt).
1980
1981 Alpha 5, 14th February 1998
1982 --------------------------
1983
1984 wxMSW:
1985
1986 - GENERIC AND MSW-SPECIFIC CODE NOW TREATED AS TWO SEPARATE
1987   DISTRIBUTIONS. This change log will therefore now refer to
1988   the Windows-specific code only. See docs/changes.txt for generic
1989   changes.
1990 - Removed Windows-specific reference counting system (GDI
1991   resources were cleaned up in idle time) - minimal
1992   advantages now we have a wxWin reference counting system.
1993 - Added missing WXDLLEXPORT keywords so DLL compilation works
1994   again.
1995 - Removed most warnings for GnuWin32 compilation.
1996 - Added wxRegion/wxRegionIterator, but haven't yet used it in
1997   e.g. wxDC.
1998
1999 Generic:
2000
2001 - GENERIC AND MSW-SPECIFIC CODE NOW TREATED AS TWO SEPARATE
2002   DISTRIBUTIONS. This change log will therefore now refer to
2003   the generic code only. See docs/msw/changes.txt for Windows-specific
2004   changes.
2005 - Readmes, change logs and installation files now go in
2006   platform-specific directories under docs, e.g. docs/msw,
2007   docs/gtk.
2008 - Added DECLARE_APP and IMPLEMENT_APP macros so wxApp object gets
2009   created dynamically, not as a global object.
2010 - Put wxColour into wx/msw/colour.h, src/msw/colour.cpp.
2011 - Changed names of some include/wx/generic headers to be
2012   consistent and to conform to gcc pragma conventions. Also
2013   changed choicesg.cpp to choicdgg.cpp.
2014 - Added gcc pragmas.
2015 - Added gtk inclusion in include/wx headers.
2016 - Added consistent file headings to source and headers.
2017 - Removed lang.cpp, lang.h and references to wxSTR_... variables;
2018   added a few references to wxTransString.
2019 - Added operator to wxTransString that converts automatically
2020   to wxString, so we can say e.g. wxMessageBox(wxTransString("Hello"), ...).
2021 - samples/internat now works (minimally).
2022 - Added wxMouseEvent::GetPosition and
2023   wxMouseEvent::GetLogicalPosition, both returning wxPoints.
2024 - Made wxSize and wxRect contain longs not ints.
2025 - Cured some memory leaks (thanks Vadim).
2026 - Tidied up OnIdle and introduced RequestMore/MoreRequested so
2027   will only keep processing OnIdle if it returns TRUE from
2028   MoreRequested.

2030 Alpha 4, 31st January 1998
2031 --------------------------
2032
2033 All:
2034
2035 - Changed wxDC functions to take longs instead of floats. GetSize now takes
2036   integer pointers, plus a version that returns a wxSize.
2037 - const keyword added to various wxDC functions.
2038 - Under Windows, wxDC no longer has any knowledge of whether
2039   an associated window is scrolled or not. Instead, the device
2040   origin is set by wxScrolledWindow in wxScrolledWindow::PrepareDC.
2041 - wxScrolledWindow applications can optionally override the virtual OnDraw
2042   function instead of using the OnPaint event handler. The wxDC passed to
2043   OnDraw will be translated by PrepareDC to reflect scrolling.
2044   When drawing outside of OnDraw, must call PrepareDC explicitly.
2045 - wxToolBarBase/wxToolBarSimple similarly changed to allow for
2046   scrolling toolbars.
2047 - Integrated wxPostScriptDC patches for 1.xx by Chris Breeze,
2048   to help printing with multiple pages.
2049 - IPC classes given base classes (wxConnectionBase etc.) which
2050   define the API used by different implementations. DDE
2051   implementation updated to use these base classes.
2052 - wxHelpInstance now separated into wxHelpControllerBase (base
2053   for all implementations), wxWinHelpController (uses standard
2054   WinHelp), wxXLPHelpController (talks to wxHelp by DDE or
2055   TCP/IP). There will be others eventually, such as
2056   wxHTMLHelpController for Microsoft (and Netscape?) HTML Help.
2057 - Added Vadim Zeitlin's wxString class plus
2058   internationalization code (gettext simulation, wxLocale, etc.).
2059   New files from Vadim:
2060   include\wx\string.h
2061   include\wx\debug.h
2062   include\wx\file.h
2063   include\wx\log.h
2064   include\wx\intl.h
2065   src\common\string.cpp
2066   src\common\log.cpp
2067   src\common\intl.cpp
2068   src\common\file.cpp
2069   No longer use GNU wxString files.
2070 - Split off file-related functions into include\wx\filefn.h and
2071   src\common\filefn.cpp.
2072 - Borland C++ support (WIN32) for main library and
2073   samples, using makefile.b32 files.
2074 - Preparation done for allowing BC++ to compile wxWin as a DLL,
2075   including changes to defs.h.
2076 - wxIntPoint removed, wxPoint is now int, and wxRealPoint
2077   introduced.
2078 - Added wxShowEvent (generated when window is being shown or
2079   hidden).
2080 - Got minimal, docview, mdi samples working for 16-bit VC++ and
2081   cured 16-bit problem with wxTextCtrl (removed global memory
2082   trick).
2083 - Updated GnuWin32 makefiles, checked minimal, mdi, docview samples.
2084
2085 Alpha 3, September 1997
2086 -----------------------
2087
2088 All:
2089
2090 - wxListCtrl, wxTreeCtrl, wxImageList classes done.
2091 - Instigated new file hierarchy, split files and classes up more logically.
2092 - PrologIO and some other utils now put into core library.
2093 - Revamped print/preview classes, added wxPageSetupDialog.
2094 - Started documentation.
2095
2096 Alpha 2, 30th April 1997
2097 ------------------------
2098
2099 All:
2100
2101 - EVT_... macros now have at least one argument, for conformance
2102   with MetroWerks compiler.
2103 - Added ids to .wxr file format.
2104 - Got Dialog Editor compiled and running again but need
2105   to extend functionality to be in line with new controls.
2106   Added dialoged\test app to allow dynamic loading of .wxr files
2107   for testing purposes.
2108 - Rewrote wxBitmap to allow installable file type
2109   handlers.
2110 - Rewrote wxBitmapButton, wxStaticBitmap to not use Fafa.
2111 - Wrote most of wxTreeCtrl and sample (need wxImageList to implement it
2112   fully).
2113 - Added back wxRadioBox.
2114 - Tidied up wx_main.cpp, wxApp class, putting PenWin code in
2115   a separate file.
2116
2117 Alpha 1, 5th April 1997
2118 -----------------------
2119
2120 Generic:
2121
2122 At this point, the following has been achieved:
2123
2124 - A lot, but not all, of the code has been revamped for better
2125   naming conventions, protection of data members, and use of
2126   wxString instead of char *.
2127 - Obsolete functionality deleted (e.g. default wxPanel layout,
2128   old system event system) and code size reduced.
2129 - Class hierarchy changed (see design doc) - base classes such
2130   as wxbWindow now removed.
2131 - No longer includes windows.h in wxWin headers, by using stand-in
2132   Windows types where needed e.g. WXHWND.
2133 - PrologIO revised.
2134 - wxScrolledWindow, wxStatusBar and new MDI classes added.
2135   MDI is now achieved using separate classes, not window styles.
2136 - wxSystemSettings added, and made use of to reflect standard
2137   Windows settings.
2138 - SetButtonFont/SetLabelFont replaced by SetFont; font and colour
2139   settings mucho rationalised.
2140 - All windows are now subclassed with the same window proc to make
2141   event handling far more consistent. Old internal wxWnd and derived
2142   classes removed.
2143 - API for controls revised, in particular addition of
2144   wxValidator parameters and removal of labels for some controls.
2145 - 1 validator written: see examples/validate.
2146 - Event table system introduced (see most samples and
2147   wx_event.cpp/ProcessEvent, wx_event.h). wxEvtHandler
2148   made more flexible, with Push/PopEventHandler allowing a chain
2149   of event handlers.
2150 - wxRadioBox removed - will be added back soon.
2151 - Toolbar class hierarchy revised:
2152   wxToolBarBase
2153   wxToolBarSimple (= old wxToolBar)
2154   wxToolBar95 (= old wxButtonBar under Win95)
2155   wxToolBarMSW (= old wxButtonBar under WIN16/WIN32)
2156 - Constraint system debugged somewhat (sizers now work properly).
2157 - wxFileDialog, wxDirDialog added; other common dialogs now
2158   have class equivalents. Generic colour and font dialogs
2159   rewritten to not need obsolete panel layout.
2160 - .wxr resource system partially reinstated, though needs
2161   an integer ID for controls. Hopefully the resource system
2162   will be replaced by something better and more efficient
2163   in the future.
2164 - Device contexts no longer stored with window and accessed
2165   with GetDC - use wxClientDC, wxPaintDC, wxWindowDC stack
2166   variables instead.
2167 - wxSlider uses trackbar class under Win95, and wxSL_LABELS flag
2168   determines whether labels are shown. Other Win95-specific flags
2169   introduced, e.g. for showing ticks.
2170 - Styles introduced for dealing with 3D effects per window, for
2171   any window: all Win95 3D effects supported, plus transparent windows.
2172 - Major change to allow 3D effect support without CTL3D, under
2173   Win95.
2174 - Bitmap versions of button and checkbox separated out into new
2175   classes, but unimplemented as yet because I intend to remove
2176   the need for Fafa - it apparently causes GPFs in Win95 OSR 2.
2177 - utils/wxprop classes working (except maybe wxPropertyFormView)
2178   in preparation for use in Dialog Editor.
2179 - GNU-WIN32 compilation verified (a month or so ago).
