                             wxWidgets Change Log
-------------------------------------------------------------------------------

Note: This file contains the list of changes since wxWidgets 3.x, please see
      docs/changes_30.txt for the changes in the previous versions.


INCOMPATIBLE CHANGES SINCE 3.0.x:
=================================

Changes in behaviour not resulting in compilation errors
--------------------------------------------------------

- wxRibbonButtonBar::DeleteButton() now deletes and not just removes the button.
- Default interpolation mode in wxGDIPlusContext under MSW is now
  wxINTERPOLATION_DEFAULT and not wxINTERPOLATION_GOOD as in 3.0 for
  consistency with OS X, call SetInterpolationQuality() explicitly if needed.

- Calling wxYield() in wxMSW now generates wxEVT_IDLE events, just as in the
  other ports, but this can be unexpected for the applications not expecting
  their idle handlers to be called from inside wxYield().

- Creating wxBitmap with 0 width or height now always fails in all ports
  (it used to succeed in wxMSW).

- Using invalid flags with wxBoxSizer or wxGridSizer items now triggers asserts
  when done from the code or error messages when done in XRC.

- wxWS_EX_VALIDATE_RECURSIVELY is now the default behaviour, i.e. calling
  Validate() or TransferData{From,To}Window() will now also call the same
  function for all children.

- wxOSX/Carbon port doesn't exist any more, wxOSX/Cocoa will be silently used
  instead even if configure --with-osx_carbon option is used.

- The pure virtual function wxAppTrait::GetToolkitVersion() now has a parameter
  for getting the micro version. If you override GetToolkitVersion() you need
  to add this new third parameter.

- wxWindow::CreateAccessible() doesn't return accessible object by default
  anymore and GetOrCreateAccessible() may return NULL, indicating that native
  system-provided accessibility should be used.

- wxMSW port doesn't always let the system process WM_SYSKEYDOWN events any
  more, make sure to call event.Skip() in your wxEVT_KEY_DOWN and/or wxEVT_CHAR
  event handlers if you want the standard key combinations such as Alt-Space or
  Alt-F4 to work.

- wxOSX port uses default button margins for wxBitmapButton by default, for
  consistency with the other ports. You now need to call SetMargins(0, 0)
  explicitly if you really don't want to have any margins in your buttons.

- wxEVT_AUINOTEBOOK_PAGE_CHANGED event is now sent after changing the page,
  as expected, and not before doing it.

- wxJoystickEvent::GetButtonChange() now returns "1 << N" for the events
  generated by the button number N under all platforms, whereas it used to
  return just "N" under Linux and macOS. Use the new GetButtonOrdinal() to
  update the existing code if necessary.


Changes in behaviour which may result in build errors
-----------------------------------------------------

- "webview" library is not included in `wx-config --libs` output any more, you
  need to request it explicitly, e.g. `wx-config --libs std,webview`.

- wxMSW now requires linking with uxtheme.lib, shlwapi.lib and version.lib.
  This is done automatically in most cases, but if you use a static build of
  the library with a non-MSVC compiler such as MinGW and do not use wx-config,
  then you will need to add these libraries to your make or project files
  yourself.

- WXWIN_OS_DESCRIPTION doesn't exist any longer, use wxGetOsDescription().

- Never documented and not always available private wxGetClipboardData()
  function now doesn't exist at all any more in wxMSW, use wxClipboard instead.

- wxGraphicsRenderer::CreatePen() now takes wxGraphicsPenInfo and not a wxPen.
  This only affects code defining its own custom renderers, code just using
  wxGraphicsContext::CreatePen() continues to compile and work as before.

- wx/treebook.h doesn't include wx/treectrl.h (and, via it, wx/textctrl.h) any
  more, include these headers explicitly from your code if necessary.

- wxHtmlDCRenderer::Render() arguments have changed, simply omit the ones not
  existing in the function signature any more to update the code using it.

- wxHtmlCell::AdjustPagebreak() has lost its "known_pagebreaks" argument,
  update your code if you override this method (you shouldn't be calling it).

- wxListCtrl::SetItem() overload taking the column index now returns bool and
  not long. Its return value hasn't changed, however, and is still always
  either true or false, so normally the existing code should continue to work.

- configure only accepts the options it knows about now and doesn't silently
  ignore all the rest. If you get errors about unknown options, you may either
  specify --disable-option-checking argument to continue accepting them (which
  only ever makes sense if you pass these options to sub-configure scripts) or,
  e.g. if the error is due to spelling an option name wrongly, fixing or
  removing its name.
