Generic wxWindows 2.0 Change Log
--------------------------------

Note: for platform-specific changes, see wx/docs/XXX/changes.txt
where XXX is one of msw, motif, xt, gtk, mac.

Alpha 11, July 3rd 1998
-----------------------

- Major work on Dialog Editor (still plenty to go).
- Expanded documentation a bit more.

Alpha 9, April 27th 1998
------------------------

- Corrected some bugs, such as the wxModule compilation problem.
- Added Gnu-Win32 b19/Mingw32 support by changing resource
  compilation and pragmas.
- Changed SIZEOF to WXSIZEOF.

Alpha 8, April 17th 1998
------------------------

- Added src/other/png, src/other/zlib directories.
- Added samples/png.
- IMPORTANT: Changed 'no id' number from 0 to -1, in wxEVT_ macros.
  Porters, please check particularly your wxTreeCtrl and wxListCtrl
  header files.
- Added modules.h/cpp, config.cpp, fileconf.cpp, textfile.cpp/h.

Alpha 7, March 30th 1998
------------------------

- Added tab classes, tab sample.
- Revised memory.cpp, memory.h slightly; memory.h now #defines
  new to WXDEBUG_NEW in DEBUG mode. Windows implementation app.cpp
  now checks for leaks on exit. Added memcheck sample.
  See src/msw/issues.txt for more details.
- resource.h, resource.cpp changed to make wxDefaultResourceTable
  a pointer. Now initialize resource system with
  wxInitializeResourceSystem and wxCleanUpResourceSystem, to
  allow better control of memory.
- wxString now derives from wxObject, to enable memory leak
  checking.
- Added some #include fixes in various files, plus changed
  float to long in wxToolBar files.

Alpha 6, March 10th 1998
------------------------

- Added Vadim's dynarray.h, dynarray.cpp.
- Added Vadim's menuitem.cpp.
- Added Windows-specific wxCheckListBox,
  owner-draw wxListBox, and drag-and-drop
  (see docs/msw/changes.txt).

Alpha 5, 14th February 1998
--------------------------

- GENERIC AND MSW-SPECIFIC CODE NOW TREATED AS TWO SEPARATE
  DISTRIBUTIONS. This change log will therefore now refer to
  the generic code only. See docs/msw/changes.txt for Windows-specific
  changes.
- Readmes, change logs and installation files now go in
  platform-specific directories under docs, e.g. docs/msw,
  docs/gtk.
- Added DECLARE_APP and IMPLEMENT_APP macros so wxApp object gets
  created dynamically, not as a global object.
- Put wxColour into wx/msw/colour.h, src/msw/colour.cpp.
- Changed names of some include/wx/generic headers to be
  consistent and to conform to gcc pragma conventions. Also
  changed choicesg.cpp to choicdgg.cpp.
- Added gcc pragmas.
- Added gtk inclusion in include/wx headers.
- Added consistent file headings to source and headers.
- Removed lang.cpp, lang.h and references to wxSTR_... variables;
  added a few references to wxTransString.
- Added operator to wxTransString that converts automatically
  to wxString, so we can say e.g. wxMessageBox(wxTransString("Hello"), ...).
- samples/internat now works (minimally).
- Added wxMouseEvent::GetPosition and
  wxMouseEvent::GetLogicalPosition, both returning wxPoints.
- Made wxSize and wxRect contain longs not ints.
- Cured some lemory leaks (thanks Vadim).
- Tidied up OnIdle and introduced RequestMore/MoreRequested so
  will only keep processing OnIdle if it returns TRUE from
  MoreRequested.

Alpha 4, 31st January 1998
--------------------------

- Changed wxDC functions to take longs instead of floats. GetSize now takes
  integer pointers, plus a version that returns a wxSize.
- const keyword added to various wxDC functions.
- Under Windows, wxDC no longer has any knowledge of whether
  an associated window is scrolled or not. Instead, the device
  origin is set by wxScrolledWindow in wxScrolledWindow::PrepareDC.
- wxScrolledWindow applications can optionally override the virtual OnDraw
  function instead of using the OnPaint event handler. The wxDC passed to
  OnDraw will be translated by PrepareDC to reflect scrolling.
  When drawing outside of OnDraw, must call PrepareDC explicitly.
- wxToolBarBase/wxToolBarSimple similarly changed to allow for
  scrolling toolbars.
- Integrated wxPostScriptDC patches for 1.xx by Chris Breeze,
  to help printing with multiple pages.
- IPC classes given base classes (wxConnectionBase etc.) which
  define the API used by different implementations. DDE
  implementation updated to use these base classes.
- wxHelpInstance now separated into wxHelpControllerBase (base
  for all implementations), wxWinHelpController (uses standard
  WinHelp), wxXLPHelPController (talks to wxHelp by DDE or
  TCP/IP). There will be others eventually, such as
  wxHTMLHelpController for Microsoft (and Netscape?) HTML Help.
- Added Vadim Zeitlin's wxString class plus
  internationalization code (gettext simulation, wxLocale, etc.).
  New files from Vadim:
  include\wx\string.h
  include\wx\debug.h
  include\wx\file.h
  include\wx\log.h
  include\wx\intl.h
  src\common\string.cpp
  src\common\log.cpp
  src\common\intl.cpp
  src\common\file.cpp
  No longer use GNU wxString files.
- Split off file-related functions into include\wx\filefn.h and
  src\common\filefn.cpp.
- Borland C++ support (WIN32) for main library and
  samples, using makefile.b32 files.
- Preparation done for allowing BC++ to compile wxWin as a DLL,
  including changes to defs.h.
- wxIntPoint removed, wxPoint is now int, and wxRealPoint
  introduced.
- Added wxShowEvent (generated when window is being shown or
  hidden).
- Got minimal, docview, mdi samples working for 16-bit VC++ and
  cured 16-bit problem with wxTextCtrl (removed global memory
  trick).
- Updated GnuWin32 makefiles, checked minimal, mdi, docview samples.

Alpha 3, September 1997
-----------------------

- wxListCtrl, wxTreeCtrl, wxImageList classes done.
- Instigated new file hierarchy, split files and classes up more logically.
- PrologIO and some other utils now put into core library.
- Revamped print/preview classes, added wxPageSetupDialog.
- Started documentation.

Alpha 2, 30th April 1997
------------------------

- EVT_... macros now have at least one argument, for conformance
  with MetroWerks compiler.
- Added ids to .wxr file format.
- Got Dialog Editor compiled and running again but need
  to extend functionality to be in line with new controls.
  Added dialoged\test app to allow dynamic loading of .wxr files
  for testing purposes.
- Rewrote wxBitmap to allow installable file type
  handlers.
- Rewrote wxBitmapButton, wxStaticBitmap to not use Fafa.
- Wrote most of wxTreeCtrl and sample (need wxImageList to implement it
  fully).
- Added back wxRadioBox.
- Tidied up wx_main.cpp, wxApp class, putting PenWin code in
  a separate file.

Alpha 1, 5th April 1997
-----------------------

At this point, the following has been achieved:

- A lot, but not all, of the code has been revamped for better
  naming conventions, protection of data members, and use of
  wxString instead of char *.
- Obsolete functionality deleted (e.g. default wxPanel layout,
  old system event system) and code size reduced.
- Class hierarchy changed (see design doc) - base classes such
  as wxbWindow now removed.
- No longer includes windows.h in wxWin headers, by using stand-in
  Windows types where needed e.g. WXHWND.
- PrologIO revised.
- wxScrolledWindow, wxStatusBar and new MDI classes added.
  MDI is now achived using separate classes, not window styles.
- wxSystemSettings added, and made use of to reflect standard
  Windows settings.
- SetButtonFont/SetLabelFont replaced by SetFont; font and colour
  settings mucho rationalised.
- All windows are now subclassed with the same window proc to make
  event handling far more consistent. Old internal wxWnd and derived
  classes removed.
- API for controls revised, in particular addition of
  wxValidator parameters and removal of labels for some controls.
- 1 validator written: see examples/validate.
- Event table system introduced (see most samples and
  wx_event.cpp/ProcessEvent, wx_event.h). wxEvtHandler
  made more flexible, with Push/PopEventHandler allowing a chain
  of event handlers.
- wxRadioBox removed - will be added back soon.
- Toolbar class hierarchy revised:
  wxToolBarBase
  wxToolBarSimple (= old wxToolBar)
  wxToolBar95 (= old wxButtonBar under Win95
  wxToolBarMSW (= old wxButtonBar under WIN16/WIN32)
- Constraint system debugged somewhat (sizers now work properly).
- wxFileDialog, wxDirDialog added; other common dialogs now
  have class equivalents. Generic colour and font dialogs
  rewritten to not need obsolete panel layout.
- .wxr resource system partially reinstated, though needs
  an integer ID for controls. Hopefully the resource system
  will be replaced by something better and more efficient
  in the future.
- Device contexts no longer stored with window and accessed
  with GetDC - use wxClientDC, wxPaintDC, wxWindowDC stack
  variables instead.
- wxSlider uses trackbar class under Win95, and wxSL_LABELS flag
  determines whether labels are shown. Other Win95-specific flags
  introduced, e.g. for showing ticks.
- Styles introduced for dealing with 3D effects per window, for
  any window: all Win95 3D effects supported, plus transparent windows.
- Major change to allow 3D effect support without CTL3D, under
  Win95.
- Bitmap versions of button and checkbox separated out into new
  classes, but unimplemented as yet because I intend to remove
  the need for Fafa - it apparently causes GPFs in Win95 OSR 2.
- utils/wxprop classes working (except maybe wxPropertyFormView)
  in preparation for use in Dialog Editor.
- GNU-WIN32 compilation verified (a month or so ago).
