   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
  51   that.
  52 - Various changes to how wxListCtrl and wxTreeCtrl react to right
  53   mouse clicks and left mouse click for starting a drag operation.
  54
  55
  56 All (GUI):
  57
  58 - added wxMediaCtrl
  59 - added wxDatePickerCtrl
  60 - wxHtmlWindow now supports background images given in <body> tag
  61 - wxSplitterWindow now supports gravity parameter (Zbigniew Zagórski)
  62 - recursive wxSizer::GetItem returns item of given window, sizer or nth index
  63 - wxLayoutConstraints now use best size, not current size, for AsIs() condition
  64 - wxSizer::Add/Insert etc. now returns pointer to wxSizerItem just added and this
  65   item remembers its wxRect area (Brian A. Vanderburg II)
  66 - wxBookCtrl renamed to wxBookCtrlBase, wxBookCtrl is reserved for most native
  67   book control (for now wxChoicebook for MSSmartphone, wxNotebook for others).
  68   Necessary event macros, types and styles mapped accordingly.
  69 - new wxBrush::IsHatch() checking for brush type replaces IS_HATCH macro
  70 - wxProgressDialog accepts smooth gauge again (wxPD_SMOOTH style)
  71 - wxProgressDialog new style: wxPD_CAN_SKIP which provides skipping some parts
  72   of the progress (with new "Skip" button in dialog)
  73
  74 Unix:
  75
  76 - wxPuts() now correctly outputs trailing new line in Unicode build
  77
  78 wxGTK:
  79
  80 - Added printing support by way of using libgnomeprint. The library
  81   now checks at runtime, if the library is installed and will use it
  82   if it is. Otherwise, it will fall back to the old PostScript printing
  83   code, from which the Pango drawing code was removed.
  84 - Implemented/improved wxDC::DrawRotatedText()
  85 - fixed wxFileDialog::SetWildcard()
  86 - native file dialog is now used if available (Zbigniew Zagorski)
  87 - implemented wxTextCtrl::Freeze() and Thaw(). The GtkTextBuffer
  88   is not a valid one during frozen state. Get a pointer to it right
  89   after wxTextCtrl creation if you really need to. (Mart Raudsepp)
  90 - Changed calls to GTK+ 2.4.x functions so that the code checks at
  91   runtime, which library version is installed so that these functions
  92   are only called with GTK+ 2.4.x installed and should yield linker
  93   errors otherwise.
  94 - wxTextCtrl text insertion efficiency fixed. (Mart Raudsepp)
  95 - Added wxRawBitmap support
  96 - Corrected Input method handler code (for Chinese etc.) and its
  97   interaction with wxWidgets' events.
  98
  99 wxMac:
 100
 101 - Vertical sliders oriented consistent with MSW/GTK (0 at top) (Kevin Hock)
 102 - wxDynamicLibrary::GetDllExt() now returns ".bundle", not ".dylib"
 103 - wxDynamicLibrary::GetSymbol() now prepends underscore to the symbol name
 104 - wxJoystick now works on OSX
 105

 109 - wxRadioButtons no longer have to be consecutive in a group
 110 - fixed spurious selection of combobox text during resize
 111 - pass correct tool id (and not always -1) to EVT_TOOL_RCLICKED() handler
 112 - added wxRegKey::Export(file)
 113
 114 wxWinCE:
 115 - Added support for MS Handheld PC 2000. This was done before 2.5.4,
 116   but not mentioned anywhere.

 118
 119 wxUniv:
 120
 121 - wxBU_... button align flags support
 122 - vertical notebook orientation support
 123 - 3rd state support for checkboxes

 125
 126 wxPalmOS:
 127
 128 - William Osborne has won and new port was born
 129   (see: "wxPalmOS porting challenge")
 130 - polishing of the port (unnecessary 2.4 API compatibility, removed
 131   all wxMSW specific code which was base for the new port)
 132 - enumeration of available volumes
 133 - native wxPrefConfig around Preferences database
 134 - native wxProgressDialog implementation

 281
 282 2.5.2
 283 -----
 284
 285 All:
 286
 287 - Hindi translation added (Dhananjaya Sharma)
 288 - Brazilian Portuguese translation added (E. A. Tacao)
 289 - wxDynamicCast() now uses static_cast<wxObject *> internally and so using it
 290   with anything not deriving from wxObject will fail at compile time (instead
 291   of run-time) now
 292 - when wxUSE_STL == 1 and STL provides quasi-standard hash_map/hash_set,
 293   wxHashMap/wxHashSet are just typedefs for them. This makes impossible
 294   to forward declare these classes.
 295
 296 All (GUI):
 297
 298 - wxHtmlWindow now delays image scaling until rendering,
 299   resulting in much better display of scaled images
 300 - Added UpdateSize to wxSplitterWindow to allow layout while hidden
 301 - implemented Freeze/Thaw() for wxGenericTreeCtrl (Kevin Hock)
 302 - support for KOI8-U encoding added (Yuriy Tkachenko)
 303 - The old wxADJUST_MINSIZE behaviour is now the default behaviour for
 304   sizer items that are windows.  This means that GetAdjustedBestSize
 305   will now be called by default to determine the minimum size that a
 306   window in a sizer should have.  If you want to still use the initial
 307   size (and not the BestSize) then use the wxFIXED_MINSIZE flag.  When
 308   windows are added to a sizer their initial size is made the window's
 309   min size using SetSizeHints, and calls to wxSizer::SetItemMinSize
 310   are also forwarded to SetSizeHints for window items.
 311 - added wxRegEx::GetMatchCount()
 312 - it is now possible to display images in wxHtmlListBox
 313
 314 wxMSW:
 315
 316 - wxWindow::Freeze()/Thaw() can now be nested
 317 - Added wxSP_NO_XP_THEME style to wxSplitterWindow to switch off
 318   XP theming (some applications look bad without 3D borders)
 319 - wxMenuBar::GetLabelTop() doesn't include '&'s in the label any more
 320 - wxRegConf couldn't read global settings without admin privileges and didn't
 321   even try to do it by default -- now it does
 322 - wxTaskBarIcon must be explicitly destroyed now, otherwise the application
 323   won't exit even though there are no top level windows
 324 - wxFileName::GetModificationTime() works with opened files too now
 325 - wxDC::GetClippingBox() now works even for clipping regions created by Windows
 326 - fixed wxFileDataObject in Unicode build (Alex D)
 327 - subindented paragraphs support (Tim Kosse)
 328
 329 wxGTK:
 330
 331 - added support for wxTE_RIGHT and wxTE_CENTRE styles under GTK2 (Mart Raudsepp)
 332
 333 wxMotif:
 334
 335 - removed wxMenuItem::DeleteSubMenu()
 336 - wxButtons use Motif default size, which is smaller than it used to be
 337   and closer to wxMSW/wxGTK look. This can be disabled by setting
 338   motif.largebuttons system option to 1 (see wxSystemOptions).
 339
 340 wxUniv/X11:
 341
 342 - implemented DrawRoundedRectangle() (clawghoul)
 343
 344 wxHTML:
 345
 346 - improved tables and lists layout algorithms (Tim Kosse)
 347 - <div> handling fix (Xavier Nodet)
 348
 349 Unix:
 350
 351 - fixed priorities of mailcap entries (David Hart)
 352 - added "wx-config --libs=std,<extra>" syntax (i.e. support for "std")
 353
 354 wxODBC:
 355
 356 - Full Unicode support is now available
 357 - BLOB support is working
 358
 359

 376 - check if file exists in wxFileConfig::DeleteFile() (Christian Sturmlechner)
 377 - when wxUSE_STL == 1 wxHashTable will not be implemented using wxHashMap

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

 693 OLD CHANGES
 694 ===========
 695
 696 INCOMPATIBLE CHANGES SINCE 2.2.x
 697 ================================
 698
 699     Please take a few minutes to read the following list, especially
 700     paying attention to the most important changes which are marked
 701     with '!' in the first column.
 702
 703     Also please note that you should ensure that WXWIN_COMPATIBILITY_2_2
 704     is defined to 1 if you wish to retain maximal compatibility with 2.2
 705     series -- however you are also strongly encouraged to try to compile
 706     your code without this define as it won't be default any longer in
 707     2.6 release.
 708
 709     NB: if you want to build your program with different major versions
 710         of wxWidgets you will probably find the wxCHECK_VERSION() macro
 711         (see the documentation) useful.
 712
 713
 714 wxBase:
 715
 716 ! wxArray<T>::Remove(size_t) has been removed to fix compilation problems
 717   under 64 bit architectures, please replace it with RemoveAt() in your
 718   code.
 719
 720 ! wxArray<T> macros have been changed to fix runtime problems under 64 bit
 721   architectures and as a side effect of this WX_DEFINE_ARRAY() can only be
 722   used now for the pointer types, WX_DEFINE_ARRAY_INT should be used for the
 723   arrays containing non-pointers.
 724
 725 - wxObject::CopyObject() and Clone() methods were removed because they
 726   simply don't make sense for all objects
 727
 728 - wxEvent now has a pure virtual Clone() method which must be implemented
 729   by all derived classes, if you have user-defined event classes please
 730   add "wxEvent *Clone() const { return new MyEvent(*this); }" line to them
 731
 732 - small change to wxStopWatch::Pause() semantics, please see the documentation
 733
 734 - unlikely but possible incompatibility: the definition of TRUE has changed
 735   from "1" to "(bool)1" (and the same thing for FALSE), so the code which
 736   could be erroneously compiled previously such as doing "return FALSE" from
 737   a function returning a pointer would stop compiling now (but this change
 738   is not supposed to have any effects on valid code)
 739
 740 - another minor change: wxApp::OnAssert() has a new "cond" argument, you
 741   must modify YourApp::OnAssert() signature if you were using it to override
 742   the default assert handling.
 743
 744 All (GUI):
 745
 746 ! the event type constants are not constants any more but are dynamically
 747   allocated during run-time which means that they can't be used as case labels
 748   in the switch()es, you must rewrite them to use if()s instead
 749
 750   You may also define WXWIN_COMPATIBILITY_EVENT_TYPES to get the old behaviour
 751   but this is strongly discouraged, please consider changing your code
 752   instead!
 753
 754 ! wxDialog does not derive from wxPanel any longer - if you were using it in
 755   your code, please update it. The quick fix for the most cases is to replace
 756   the occurrences of wxPanel with wxWindow.
 757
 758 ! if you handle (and don't skip) EVT_KEY_DOWN, the EVT_CHAR event is not
 759   generated at all, so you must call event.Skip() in your OnKeyDown() if
 760   you want to get OnChar() as well
 761
 762 - in general, the key events sent for the various non ASCII key combinations
 763   have been changed to make them consistent over all supported platforms,
 764   please see the wxKeyEvent documentation for details
 765
 766 - wxYES_NO is now wxYES | wxNO and the manifest values of both wxYES and wxNO
 767   have changed (to fix some unfortunate clashes), please check your code to
 768   ensure that no tests for wxYES or wxNO are broken: for example, the following
 769   will *NOT* work any longer:
 770
 771         if ( flags & wxYES_NO )
 772                 ... do something ...
 773         if ( flags & wxYES )
 774                 ... do something else ...
 775
 776 - static wxWizard::Create() doesn't exist any more, the wizards are created
 777   in the same way as all the other wxWindow objects, i.e. by directly using
 778   the ctor
 779
 780 - wxGLCanvas now derives directly from wxWindow, not wxScrolledWindow
 781
 782 - wxGridCellAttrProvider class API changed, you will need to update your code
 783   if you derived any classes from it
 784
 785 - wxImage::ComputeHistogram()'s signature changed to
 786   unsigned long ComputeHistogram(wxImageHistogram&) const
 787
 788 - wxEvtHandler cannot be copied/assigned any longer - this never worked but
 789   now it results in compile-time error instead of run-time crashes
 790
 791 - WXK_NUMLOCK and WXK_SCROLL keys no longer result in EVT_CHAR() events,
 792   they only generate EVT_KEY_DOWN/UP() ones
 793
 794 - the dialogs use wxApp::GetTopWindow() as the parent implicitly if the
 795   parent specified is NULL, use wxDIALOG_NO_PARENT style to prevent this
 796   from happening
 797
 798 - several obsolete synonyms are only retained in WXWIN_COMPATIBILITY_2_2 mode:
 799   for example, use wxScrolledWindow::GetViewStart() now instead of ViewStart()
 800   and GetCount() instead of Number() in many classes
 801
 802 - wxCmdLineParser does not use wxLog to output messages anymore.
 803   to obtain the previous behaviour, add
 804   wxMessageOutput::Set(new wxMessageOutputLog); to your program
 805   (you will need to #include <wx/msgout.h>)
 806
 807 wxMSW:
 808
 809 ! build system changed: setup.h is not a static file in include/wx any more
 810   but is created as part of the build process under lib/<toolkit>/wx
 811   where <toolkit> is of the form (msw|univ)[dll][u][d]. You'll need to update
 812   the include path in your make/project files appropriately. Furthermore,
 813   xpm.lib is no longer used by wxMSW, it was superseded by the wxXPMDecoder
 814   class. You'll need to remove all references to xpm.lib from your
 815   make/project files. Finally, the library names have changed as well and now
 816   use the following consistent naming convention: wxmsw[ver][u][d].(lib|dll)
 817   where 'u' appears for Unicode version, 'd' -- for the debug one and version
 818   is only present for the DLLs builds.
 819
 820 - child frames appear in the taskbar by default now, use wxFRAME_NO_TASKBAR
 821   style to avoid it
 822
 823 - all overloads of wxDC::SetClippingRegion() combine the given region with the
 824   previously selected one instead of replacing it
 825
 826 - wxGetHomeDir() uses HOME environment variable and if it is set will not
 827   return the programs directory any longer but its value (this function has
 828   never been meant to return the programs directory anyhow)
 829
 830 - wxHTML apps don't need to include wx/html/msw/wxhtml.rc in resources file
 831   anymore. The file was removed from wxMSW
 832
 833
 834 Unix ports:
 835
 836 ! You should use `wx-config --cxxflags` in your makefiles instead of
 837   `wx-config --cflags` for compiling C++ files. CXXFLAGS contains CFLAGS
 838   and the compiler flags for C++ files only, CFLAGS should still be used
 839   to compile pure C files.
 840
 841
 842 wxThread and related classes:
 843
 844 - The thread-related classes have been heavily changed since 2.2.x versions
 845   as the old code had many serious problems. This could have resulted in
 846   semantical changes other than those mentioned here, please review use of
 847   wxThread, wxMutex and wxCondition classes in your code.
 848
 849 ! wxCondition now *must* be used with a mutex, please read the (updated) class
 850   documentation for details and revise your code accordingly: this change was
 851   unfortunately needed as it was impossible to ensure the correct behaviour
 852   (i.e. absence of race conditions) using the old API.
 853
 854 - wxMutex is not recursive any more in POSIX implementation (it hasn't been
 855   recursive in 2.2.x but was in 2.3.1 and 2.3.2), please refer to the class
 856   documentation for the discussion of the recursive mutexes.
 857
 858 - wxMutex::IsLocked() doesn't exist any more and should have never existed:
 859   this is was unique example of a thread-unsafe-by-design method.
 860

1516 - Added BC++ 5 IDE files and instructions.
1517 - Fixed wxChoice, wxComboBox constructor bugs (m_noStrings initialisation).
1518 - Fixed focus-related crash.
1519
1520 wxMotif:
1521
1522 - Cured asynchronous wxExecute crash.
1523 - Added repaint event handlers to wxFrame, wxMDIChildFrame.
1524
1525 General:
1526
1527 - wxLocale documented.
1528 - Added include filenames to class reference.
1529 - wxHelpController API changed: SetBrowser becomes SetViewer,
1530   DisplaySection works for WinHelp, help sample compiles under Windows
1531   (though doesn't display help yet).
1532
1533 Beta 4, February 12th 1999
1534 --------------------------
1535
1536 wxGTK:
1537
1538 - Miscellaneous fixes.
1539
1540 wxMSW:
1541
1542 - Makefiles for more compilers and samples; Cygwin makefiles
1543   rationalised.

1545
1546 wxMotif:
1547
1548 - Added OnEraseBackground invocation.
1549 - Added wxRETAINED implementation for wxScrolledWindow.
1550 - Cured scrolling display problem by adding XmUpdateDisplay.
1551 - Tried to make lex-ing in the makefile more generic (command line
1552   syntax should apply to both lex and flex).
1553 - Changed file selector colours for consistency (except for buttons:
1554   crashes for some reason).
1555 - Fixed wxMotif version of wxImage::ConvertToBitmap (used new instead
1556   of malloc, which causes memory problems).
1557
1558 General:
1559
1560 - Further doc improvements.
1561 - wxGenericValidator added.
1562 - Added wxImageModule to image.cpp, so adds/cleans up standard handlers
1563   automatically.
1564
1565 Beta 3, January 31st 1999
1566 -------------------------
1567
1568 wxGTK:

1571 - wxToolTip class added.
1572 - Miscellaneous fixes.
1573

1598 --------------------
1599
1600 wxGTK:
1601
1602 wxMSW:
1603
1604 - 16-bit BC++ compilation/linking works albeit without the resource system.
1605
1606 wxMotif:
1607
1608 - Cured wxScreenDC origin problem so e.g. sash window sash is drawn at
1609   the right place.
1610 - Cured some widget table clashes.
1611 - Added thread support (Robert).
1612 - wxPoem sample now works.
1613
1614 General:
1615
1616 - Rearranged documentation a bit.
1617 - Sash window uses area of first frame/dialog to paint over when drawing
1618   the dragged sash, not just the sash window itself (it clipped to the right
1619   or below).
1620 - Made resource sample use the correct Cancel button id.
1621 - Moved wxProp to main library (generic directory), created proplist
1622   sample.
1623 - Added bombs and fractal samples.
1624
1625 Beta 1, December 24th 1998
1626 --------------------------
1627
1628 wxGTK:
1629
1630 - Various
1631
1632 wxMSW, wxMotif: not in sync with this release.
1633
1634
1635 Alpha 18, December 29th 1998
1636 ----------------------------
1637
1638 wxMSW:
1639
1640 - Win16 support working again (VC++ 1.5)
1641 - Win16 now uses generic wxNotebook, wxListCtrl,
1642   wxTreeCtrl -- more or less working now, although
1643   a little work on wxNotebook is still needed.
1644   Under 16-bit Windows, get assertion when you click
1645   on a tab.
1646 - Wrote 16-bit BC++ makefiles: samples don't yet link.
1647 - Added CodeWarrior support to distribution courtesy
1648   of Stefan Csomor.
1649
1650 wxMotif:
1651
1652 - Cured scrolling problem: scrollbars now show/hide themselves
1653   without (permanently) resizing the window.
1654 - Removed some commented-out lines in wxScrolledWindow::AdjustScrollbars
1655   that disabled scrollbar paging.
1656 - Set background colour of drawing area in wxWindow, so e.g. wxListCtrl
1657   colours correctly.
1658 - Removed major bug whereby dialogs were unmanaged automatically
1659   when any button was pressed.
1660 - Fixed colours of wxWindow scrollbars, made list and text controls
1661   have a white background.
1662 - Fixed dialog colour setting.
1663 - Added settable fonts and colours for wxMenu/wxMenuBar. Now
1664   they have sensible colours by default.
1665 - Fixed a bug in wxStaticBox.
1666 - Cured wxTreeCtrl bug: now works pretty well!
1667 - Debugged DrawEllipticArc (a ! in the wrong place).
1668 - Added SetClippingRegion( const wxRegion& region ).
1669 - Added wxPoint, wxSize, wxRect versions of SetSize etc.
1670
1671 Alpha 17, November 22nd 1998
1672 ----------------------------
1673
1674 wxMSW:
1675
1676 - More documentation updates, especially for
1677   wxLayoutWindow classes and debugging facilities.
1678 - Changed wxDebugContext to use wxDebugLog instead
1679   of wxTrace.
1680 - Now supports VC++ 6.0, and hopefully BC++ 5.0.
1681   However, DLL support may be broken for BC++ since
1682   VC++ 6 required changing of WXDLLEXPORT keyword
1683   position.
1684 - Numerous miscellaneous changes.
1685
1686 wxMotif:
1687
1688 - Reimplemented MDI using wxNotebook instead of the MDI widgets, which
1689   were too buggy (probably not design for dynamic addition/removal of
1690   child frames).
1691 - Some improvements to the wxNotebook implementation.
1692 - wxToolBar now uses a bulletin board instead of a form, in an attempt
1693   to make it possible to add ordinary wxControls to a toolbar.
1694 - Cured problem with not being able to use global memory operators,
1695   by defining two more global operators, so that the delete will match
1696   the debugging implementation.
1697 - Added wxUSE_DEBUG_NEW_ALWAYS so we can distinguish between using
1698   global memory operators (usually OK) and #defining new to be
1699   WXDEBUG_NEW (sometimes it might not be OK).
1700 - Added time.cpp to makefile; set wxUSE_DATETIME to 1.
1701 - Added a parent-existence check to popup menu code to make it not crash.
1702 - Added some optimization in wxWindow::SetSize to produce less flicker.
1703   It remains to be seen whether this produces any resize bugs.
1704
1705 It's a long time since I updated this file. Previously done:
1706
1707 - wxFrame, wxDialog done.
1708 - wxScrolledWindow done (but backing pixmap not used at present).
1709 - wxBitmap done though could be tidied it up at some point.
1710 - Most basic controls are there, if not rigorously tested.
1711 - Some MDI support (menus appear on child frames at present).
1712 - wxNotebook almost done.
1713 - wxToolBar done (horizontal only, which would be easy to extend
1714   to vertical toolbars).
1715
1716 More recently:
1717
1718 - Colour and font changing done (question mark over what happens
1719   to scrollbars).
1720 - Accelerators done (for menu items and buttons). Also event loop
1721   tidied up in wxApp so that events are filtered through ProcessXEvent.
1722 - wxWindow::GetUpdateRegion should now work.
1723
1724 Alpha 16, September 8th 1998
1725 ----------------------------
1726
1727 wxMSW:
1728
1729 - Added wxSashWindow, wxSashLayoutWindow classes, and sashtest
1730   sample.
1731 - Guilhem's socket classes added, plus wxsocket sample.
1732 - A few more makefiles added.
1733 - GnuWin32/BC++ compatibility mods.
1734 - Further doc updates.
1735 - wxProp updates for correct working with wxGTK.
1736
1737 wxMotif:
1738
1739 - First start at Motif port.
1740 - Made makefiles for wxMotif source directory and minimal sample.
1741 - First go at wxApp, wxWindow, wxDialog, wxPen, wxBrush, wxFont,
1742   wxColour, wxButton, wxCheckBox, wxTextCtrl, wxStaticText,
1743   wxMenu, wxMenuItem, wxMenuBar
1744
1745 Alpha 15, August 31st 1998
1746 --------------------------
1747
1748 wxMSW:
1749
1750 - wxBitmap debugged.
1751 - wxDC::GetDepth added.
1752 - Contribution added whereby wxBitmap will be
1753   converted to DC depth if they don't match.
1754 - wxConfig API improved, documentation updated.
1755 - Printing classes name conventions cleaned up.
1756 - wxUpdateUIEvent now derives from wxCommandEvent
1757   so event can travel up the window hierarchy.
1758
1759 Alpha 14, July 31st 1998
1760 ------------------------
1761
1762 wxMSW:
1763
1764 - Toolbar API has been simplified, and now
1765   wxFrame::GetClientArea returns the available client
1766   area when toolbar, status bar etc. have been accounted for.
1767   wxFrame::CreateToolBar added in line with CreateStatusBar.
1768 - Documentation updates, incl. for wxToolBar.
1769 - New wxAcceleratorTable class plus wxFrame::SetAcceleratorTable.
1770 - Various additions from other folk, e.g. streams, wxConfig
1771   changes, wxNotebook.
1772 - Added wxDocMDIParentFrame, wxDocMDIChildFrame for doc/view.
1773
1774 Alpha 13, July 8th 1998
1775 -----------------------
1776
1777 wxMSW:
1778
1779 - Implemented wxPoint as identical to POINT on Windows, and
1780   altered wxDC wxPoint functions to use wxPoint directly in
1781   Windows functions, for efficiency.
1782 - Cured wxASSERT bug in wxStatusBar95.
1783 - #ifdefed out some bits in oleutils.cpp for compilers that
1784   don't support it.
1785 - Added some operators to wxPoint, wxSize.
1786 - Added inline wxDC functions using wxPoint, wxSize, wxRect.
1787
1788 Alpha 12, July 7th 1998
1789 -----------------------
1790
1791 wxMSW:
1792
1793 - Added wxApp::GetComCtl32Version, and wxTB_FLAT style, so can
1794   have flat toolbars on Win98 or Win95 with IE >= 3 installed.
1795
1796 Alpha 11, July 3rd 1998
1797 -----------------------
1798
1799 wxMSW:
1800
1801 - Added thread.h, thread.cpp.
1802 - Changed Enabled, Checked to IsEnabled, IsChecked in wxMenu,
1803   wxMenuBar.
1804 - Changed wxMenuItem::SetBackColor to SetBackgroundColour,
1805   SetTextColor to SetTextColour, and added or made public several
1806   wxMenuItem accessors.
1807 - Added two overloads to wxRegion::Contains. Added
1808   wxRegion::IsEmpty for a more consistent naming convention.
1809 - Added Vadim's wxDataObject and wxDropSource.
1810 - ENTER/LEAVE events now work.
1811 - Cured wxMemoryDC bug where the DC wasn't being deleted.
1812 - Cured wxGauge SetSize major bugginess.
1813 - Cured problem where if a GDI object was created on the stack,
1814   then went out of scope, then another object was selected into
1815   the DC, GDI objects would leak. This is because the assignment
1816   to e.g. wxDC::m_pen would delete the GDI object without it first
1817   being selected out of the DC. Cured by selecting the old DC object
1818   first, then doing the assignment.
1819 - Split up wxGaugeMSW, wxGauge95, wxSliderMSW, wxSlider95
1820 - Various other bug fixes and additions.
1821
1822 Generic:
1823
1824 - Major work on Dialog Editor (still plenty to go).
1825 - Expanded documentation a bit more.
1826
1827 Alpha 10, May 7th 1998
1828 ----------------------
1829
1830 wxMSW:
1831
1832 - Added desiredWidth, desiredHeight parameters to wxBitmapHandler
1833   and wxIcon functions so that you can specify what size of
1834   icon should be loaded. Probably will remain a Windows-specific thing.
1835 - wxStatusBar95 now works for MDI frames.
1836 - Toolbars in MDI frames now behave normally. They still
1837   require application-supplied positioning code though.
1838 - Changed installation instructions, makefiles and batch files
1839   for compiling with Gnu-Win32/Mingw32/EGCS. Also timercmn.cpp
1840   change to support Mingw32/EGCS. Bison now used by default.
1841
1842 Alpha 9, April 27th 1998
1843 ------------------------
1844
1845 wxMSW:
1846
1847 - Cured bug in wxStatusBar95 that caused a crash if multiple
1848   fields were used.
1849 - Added Gnu-Win32 b19/Mingw32 support by changing resource
1850   compilation and pragmas.
1851 - Cured wxMenu bug introduced in alpha 8 - didn't respond to
1852   commands because VZ changed the id setting in wxMenu::MSWCommand.
1853
1854 Generic:
1855
1856 - Corrected some bugs, such as the wxModule compilation problem.
1857 - Added Gnu-Win32 b19/Mingw32 support by changing resource
1858   compilation and pragmas.
1859 - Changed SIZEOF to WXSIZEOF.
1860
1861 Alpha 8, April 17th 1998
1862 ------------------------
1863
1864 wxMSW:
1865
1866 - Added IsNull to wxGDIObject to check if the ref data is present or not.
1867 - Added PNG handler and sample - doesn't work for 16-bit PNGs for
1868   some reason :-(
1869 - Added wxJoystick class and event handling, and simple demo.
1870 - Added simple wxWave class. Needs Stop() function.
1871 - Added wxModule (module.h/module.cpp) to allow definition
1872   of modules to be initialized and cleaned up on wxWidgets
1873   startup/exit.
1874 - Start of Mingw32 compatibility (see minimal and dialogs samples
1875   makefile.m95 files, and install.txt).
1876 - Note: Windows printing has stopped working... will investigate.
1877 VADIM'S CHANGES:
1878 - Updated wxString: bug fixes, added wxArrayString, some
1879   compatibility functions.
1880 - Updated log.h/cpp, added wxApp::CreateLogTarget.
1881 - file.h: new wxTempFile class.
1882 - defs.h: added wxSB_SIZE_GRIP for wxStatusBar95
1883 - statbr95: wxStatusBar95 control.
1884 - registry.h/cpp: wxRegKey class for Win95 registry.
1885 - listbox.cpp: corrected some bugs with owner-drawn listboxes.
1886 - wxConfig and wxFileConfig classes.
1887
1888 Generic:
1889
1890 - Added src/other/png, src/other/zlib directories.
1891 - Added samples/png.
1892 - IMPORTANT: Changed 'no id' number from 0 to -1, in wxEVT_ macros.
1893   Porters, please check particularly your wxTreeCtrl and wxListCtrl
1894   header files.
1895 - Added modules.h/cpp, config.cpp, fileconf.cpp, textfile.cpp/h.
1896
1897 Alpha 7, March 30th 1998
1898 ------------------------
1899
1900 wxMSW:
1901
1902 - Added tab classes, tab sample.
1903 - Now can return FALSE from OnInit and windows will be
1904   cleaned up properly before exit.
1905 - Improved border handling so panels don't get borders
1906   automatically.
1907 - Debugged MDI activation from Window menu.
1908 - Changes to memory debug handling, including checking for
1909   memory leaks on application exit - but see issues.txt for
1910   unresolved issues.
1911 - Added wxTaskBarIcon (taskbar.cpp/h, plus samples/taskbar)
1912   to allow maintenance of an icon in the Windows 95 taskbar
1913   tray area.
1914 - Got MFC sample working (MFC and wxWidgets in the same
1915   application), partly by tweaking ntwxwin.mak settings.
1916 - Got DLL compilation working again (VC++).
1917 - Changed wxProp/Dialog Editor filenames.
1918
1919 Generic:
1920
1921 - Added tab classes, tab sample.
1922 - Revised memory.cpp, memory.h slightly; memory.h now #defines
1923   new to WXDEBUG_NEW in DEBUG mode. Windows implementation app.cpp
1924   now checks for leaks on exit. Added memcheck sample.
1925   See src/msw/issues.txt for more details.
1926 - resource.h, resource.cpp changed to make wxDefaultResourceTable
1927   a pointer. Now initialize resource system with
1928   wxInitializeResourceSystem and wxCleanUpResourceSystem, to
1929   allow better control of memory.
1930 - wxString now derives from wxObject, to enable memory leak
1931   checking.
1932 - Added some #include fixes in various files, plus changed
1933   float to long in wxToolBar files.
1934
1935 Alpha 6, March 10th 1998
1936 ------------------------
1937
1938 wxMSW:
1939
1940 - Found stack error bug - stopped unwanted OnIdle recursion.
1941 - Removed bug in wxTreeCtrl::InsertItem I added in alpha 5.
1942 - Changed exit behaviour in wxApp/wxFrame/wxDialog. Now will
1943   check if the number of top-level windows is zero before
1944   exiting. Also, wxApp::GetTopWindow will return either
1945   m_topWindow or the first member of wxTopLevelWindows, so you
1946   don't have to call wxApp::SetTopWindow.
1947 - Added dynarray.h/dynarray.cpp (from Vadim).
1948 - Added first cut at OLE drag and drop (from Vadim). dnd sample
1949   added. Drop target only at this stage. See src/msw/ole/*.cpp,
1950   wx/include/msw/ole/*.h. WIN32 only because of UUID usage.
1951   Doesn't work with GnuWin32 - no appropriate headers e.g. for
1952   IUnknown.
1953   Doesn't work with BC++ either - crashes on program startup.
1954 - Added Vadim's owner-draw modifications - will probably remain
1955   Windows-only. This enhances wxMenu, wxListBox. See ownerdrw sample.
1956 - Added wxLB_OWNERDRAW for owner-draw listboxes.
1957 - Vadim's wxCheckListBox derives from wxListBox. See checklst sample.
1958   Doesn't entirely work for WIN16.
1959 - Vadim has added wxMenuItem as a separate file menuitem.cpp. It
1960   can also be used as an argument to wxMenu::Append, not just for
1961   internal implementation.
1962 - Some #ifdefs done for MINGW32 compilation (just alter OPTIONS
1963   in makeg95.env, together with mingw32.bat). However, resource
1964   binding is not working yet so most apps with dialogs crash.
1965
1966 Generic:
1967
1968 - Added Vadim's dynarray.h, dynarray.cpp.
1969 - Added Vadim's menuitem.cpp.
1970 - Added Windows-specific wxCheckListBox,
1971   owner-draw wxListBox, and drag-and-drop
1972   (see docs/msw/changes.txt).
1973
1974 Alpha 5, 14th February 1998
1975 --------------------------
1976
1977 wxMSW:
1978
1979 - GENERIC AND MSW-SPECIFIC CODE NOW TREATED AS TWO SEPARATE
1980   DISTRIBUTIONS. This change log will therefore now refer to
1981   the Windows-specific code only. See docs/changes.txt for generic
1982   changes.
1983 - Removed Windows-specific reference counting system (GDI
1984   resources were cleaned up in idle time) - minimal
1985   advantages now we have a wxWin reference counting system.
1986 - Added missing WXDLLEXPORT keywords so DLL compilation works
1987   again.
1988 - Removed most warnings for GnuWin32 compilation.
1989 - Added wxRegion/wxRegionIterator, but haven't yet used it in
1990   e.g. wxDC.
1991
1992 Generic:
1993
1994 - GENERIC AND MSW-SPECIFIC CODE NOW TREATED AS TWO SEPARATE
1995   DISTRIBUTIONS. This change log will therefore now refer to
1996   the generic code only. See docs/msw/changes.txt for Windows-specific
1997   changes.
1998 - Readmes, change logs and installation files now go in
1999   platform-specific directories under docs, e.g. docs/msw,
2000   docs/gtk.
2001 - Added DECLARE_APP and IMPLEMENT_APP macros so wxApp object gets
2002   created dynamically, not as a global object.
2003 - Put wxColour into wx/msw/colour.h, src/msw/colour.cpp.
2004 - Changed names of some include/wx/generic headers to be
2005   consistent and to conform to gcc pragma conventions. Also
2006   changed choicesg.cpp to choicdgg.cpp.
2007 - Added gcc pragmas.
2008 - Added gtk inclusion in include/wx headers.
2009 - Added consistent file headings to source and headers.
2010 - Removed lang.cpp, lang.h and references to wxSTR_... variables;
2011   added a few references to wxTransString.
2012 - Added operator to wxTransString that converts automatically
2013   to wxString, so we can say e.g. wxMessageBox(wxTransString("Hello"), ...).
2014 - samples/internat now works (minimally).
2015 - Added wxMouseEvent::GetPosition and
2016   wxMouseEvent::GetLogicalPosition, both returning wxPoints.
2017 - Made wxSize and wxRect contain longs not ints.
2018 - Cured some memory leaks (thanks Vadim).
2019 - Tidied up OnIdle and introduced RequestMore/MoreRequested so
2020   will only keep processing OnIdle if it returns TRUE from
2021   MoreRequested.
2022
2023 Alpha 4, 31st January 1998
2024 --------------------------
2025
2026 All:
2027
2028 - Changed wxDC functions to take longs instead of floats. GetSize now takes
2029   integer pointers, plus a version that returns a wxSize.
2030 - const keyword added to various wxDC functions.
2031 - Under Windows, wxDC no longer has any knowledge of whether
2032   an associated window is scrolled or not. Instead, the device
2033   origin is set by wxScrolledWindow in wxScrolledWindow::PrepareDC.
2034 - wxScrolledWindow applications can optionally override the virtual OnDraw
2035   function instead of using the OnPaint event handler. The wxDC passed to
2036   OnDraw will be translated by PrepareDC to reflect scrolling.
2037   When drawing outside of OnDraw, must call PrepareDC explicitly.
2038 - wxToolBarBase/wxToolBarSimple similarly changed to allow for
2039   scrolling toolbars.
2040 - Integrated wxPostScriptDC patches for 1.xx by Chris Breeze,
2041   to help printing with multiple pages.
2042 - IPC classes given base classes (wxConnectionBase etc.) which
2043   define the API used by different implementations. DDE
2044   implementation updated to use these base classes.
2045 - wxHelpInstance now separated into wxHelpControllerBase (base
2046   for all implementations), wxWinHelpController (uses standard
2047   WinHelp), wxXLPHelpController (talks to wxHelp by DDE or
2048   TCP/IP). There will be others eventually, such as
2049   wxHTMLHelpController for Microsoft (and Netscape?) HTML Help.
2050 - Added Vadim Zeitlin's wxString class plus
2051   internationalization code (gettext simulation, wxLocale, etc.).
2052   New files from Vadim:
2053   include\wx\string.h
2054   include\wx\debug.h
2055   include\wx\file.h
2056   include\wx\log.h
2057   include\wx\intl.h
2058   src\common\string.cpp
2059   src\common\log.cpp
2060   src\common\intl.cpp
2061   src\common\file.cpp
2062   No longer use GNU wxString files.
2063 - Split off file-related functions into include\wx\filefn.h and
2064   src\common\filefn.cpp.
2065 - Borland C++ support (WIN32) for main library and
2066   samples, using makefile.b32 files.
2067 - Preparation done for allowing BC++ to compile wxWin as a DLL,
2068   including changes to defs.h.
2069 - wxIntPoint removed, wxPoint is now int, and wxRealPoint
2070   introduced.
2071 - Added wxShowEvent (generated when window is being shown or
2072   hidden).
2073 - Got minimal, docview, mdi samples working for 16-bit VC++ and
2074   cured 16-bit problem with wxTextCtrl (removed global memory
2075   trick).
2076 - Updated GnuWin32 makefiles, checked minimal, mdi, docview samples.
2077
2078 Alpha 3, September 1997
2079 -----------------------
2080
2081 All:
2082
2083 - wxListCtrl, wxTreeCtrl, wxImageList classes done.
2084 - Instigated new file hierarchy, split files and classes up more logically.
2085 - PrologIO and some other utils now put into core library.
2086 - Revamped print/preview classes, added wxPageSetupDialog.
2087 - Started documentation.
2088
2089 Alpha 2, 30th April 1997
2090 ------------------------
2091
2092 All:
2093
2094 - EVT_... macros now have at least one argument, for conformance
2095   with MetroWerks compiler.
2096 - Added ids to .wxr file format.
2097 - Got Dialog Editor compiled and running again but need
2098   to extend functionality to be in line with new controls.
2099   Added dialoged\test app to allow dynamic loading of .wxr files
2100   for testing purposes.
2101 - Rewrote wxBitmap to allow installable file type
2102   handlers.
2103 - Rewrote wxBitmapButton, wxStaticBitmap to not use Fafa.
2104 - Wrote most of wxTreeCtrl and sample (need wxImageList to implement it
2105   fully).
2106 - Added back wxRadioBox.
2107 - Tidied up wx_main.cpp, wxApp class, putting PenWin code in
2108   a separate file.
2109
2110 Alpha 1, 5th April 1997
2111 -----------------------
2112
2113 Generic:
2114
2115 At this point, the following has been achieved:
2116
2117 - A lot, but not all, of the code has been revamped for better
2118   naming conventions, protection of data members, and use of
2119   wxString instead of char *.
2120 - Obsolete functionality deleted (e.g. default wxPanel layout,
2121   old system event system) and code size reduced.
2122 - Class hierarchy changed (see design doc) - base classes such
2123   as wxbWindow now removed.
2124 - No longer includes windows.h in wxWin headers, by using stand-in
2125   Windows types where needed e.g. WXHWND.
2126 - PrologIO revised.
2127 - wxScrolledWindow, wxStatusBar and new MDI classes added.
2128   MDI is now achieved using separate classes, not window styles.
2129 - wxSystemSettings added, and made use of to reflect standard
2130   Windows settings.
2131 - SetButtonFont/SetLabelFont replaced by SetFont; font and colour
2132   settings mucho rationalised.
2133 - All windows are now subclassed with the same window proc to make
2134   event handling far more consistent. Old internal wxWnd and derived
2135   classes removed.
2136 - API for controls revised, in particular addition of
2137   wxValidator parameters and removal of labels for some controls.
2138 - 1 validator written: see examples/validate.
2139 - Event table system introduced (see most samples and
2140   wx_event.cpp/ProcessEvent, wx_event.h). wxEvtHandler
2141   made more flexible, with Push/PopEventHandler allowing a chain
2142   of event handlers.
2143 - wxRadioBox removed - will be added back soon.
2144 - Toolbar class hierarchy revised:
2145   wxToolBarBase
2146   wxToolBarSimple (= old wxToolBar)
2147   wxToolBar95 (= old wxButtonBar under Win95)
2148   wxToolBarMSW (= old wxButtonBar under WIN16/WIN32)
2149 - Constraint system debugged somewhat (sizers now work properly).
2150 - wxFileDialog, wxDirDialog added; other common dialogs now
2151   have class equivalents. Generic colour and font dialogs
2152   rewritten to not need obsolete panel layout.
2153 - .wxr resource system partially reinstated, though needs
2154   an integer ID for controls. Hopefully the resource system
2155   will be replaced by something better and more efficient
2156   in the future.
2157 - Device contexts no longer stored with window and accessed
2158   with GetDC - use wxClientDC, wxPaintDC, wxWindowDC stack
2159   variables instead.
2160 - wxSlider uses trackbar class under Win95, and wxSL_LABELS flag
2161   determines whether labels are shown. Other Win95-specific flags
2162   introduced, e.g. for showing ticks.
2163 - Styles introduced for dealing with 3D effects per window, for
2164   any window: all Win95 3D effects supported, plus transparent windows.
2165 - Major change to allow 3D effect support without CTL3D, under
2166   Win95.
2167 - Bitmap versions of button and checkbox separated out into new
2168   classes, but unimplemented as yet because I intend to remove
2169   the need for Fafa - it apparently causes GPFs in Win95 OSR 2.
2170 - utils/wxprop classes working (except maybe wxPropertyFormView)
2171   in preparation for use in Dialog Editor.
2172 - GNU-WIN32 compilation verified (a month or so ago).
