-------------------------------------------------------------------------------

INCOMPATIBLE CHANGES SINCE 2.8.x
================================

Unicode-related changes
-----------------------

The biggest changes in wxWidgets 3.0 are the changes due to the merge of the
old ANSI and Unicode build modes in a single build. See the Unicode overview
in the manual for more details but here are the most important incompatible
changes:

- Many wxWidgets functions taking "const wxChar *" have been changed to take
  either "const wxString&" so that they accept both Unicode and ANSI strings.
  and the argument can't be NULL or "const char *" if the strings are always
  ANSI but may be NULL. This change is normally backwards compatible except:

  a) Virtual functions: derived classes versions must be modified to take
     "const wxString&" as well to make sure that they continue to override the
     base class version.

  b) Passing NULL as argument: as NULL can't be unambiguously converted to
     wxString, in many cases code using it won't compile any more and NULL
     should be replaced with an empty string.


- Some structure fields which used to be of type "const wxChar *" (such as
  wxCmdLineEntryDesc::shortName, longName and description fields) are now of
  type "const char *", you need to remove wxT() or _T() around the values used
  to initialize them (which should normally always be ASCII).

- wxIPC classes didn't work correctly in Unicode build before, this was fixed
  but at a price of breaking backwards compatibility: many methods which used
  to work with "wxChar *" before use "void *" now (some int parameters were
  also changed to size_t). While wxIPC_TEXT can still be used to transfer 7
  bit text, the new wxIPC_UTF8TEXT format is used for transferring wxStrings.


wxODBC library removal
----------------------

wxODBC library was unmaintained since several years and we couldn't continue
supporting it any longer so it was removed. Please use any of the other open
source ODBC libraries in the future projects.


Changes in behaviour not resulting in compilation errors, please read this!
---------------------------------------------------------------------------

- Default location of wxFileConfig files has changed under Windows, you will
  need to update your code if you access these files directly.

- wxWindow::IsEnabled() now returns false if a window parent (and not
  necessarily the window itself) is disabled, new function IsThisEnabled()
  with the same behaviour as old IsEnabled() was added.

- Generating wxNavigationKeyEvent events doesn't work any more under wxGTK (and
  other platforms in the future), use wxWindow::Navigate() or NavigateIn()
  instead.

- Sizers distribute only the extra space between the stretchable items
  according to their proportions and not all available space. We believe the
  new behaviour corresponds better to user expectations but if you did rely
  on the old behaviour you will have to update your code to set the minimal
  sizes of the sizer items to be in the same proportion as the items
  proportions to return to the old behaviour.

- wxWindow::Freeze/Thaw() are not virtual any more, if you overrode them in
  your code you need to override DoFreeze/Thaw() instead now.


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

- WXWIN_COMPATIBILITY_2_4 doesn't exist any more, please update your code if
  you still relied on features deprecated since version 2.4

- wxDC classes hierarchy has changed, if you derived any classes from wxDC you
  need to review them as wxDC doesn't have any virtual methods any longer and
  uses delegation instead of inheritance to present different behaviours.

- Return type of wxString::operator[] and wxString::iterator::operator* is no
  longer wxChar (i.e. char or wchar_t), but wxUniChar. This is not a problem
  in vast majority of cases because of conversion operators, but it can break
  code that depends on the result being wxChar.

- The value returned by wxString::c_str() cannot be casted to non-const char*
  or wchar_t* anymore. The solution is to use newly added wxString methods
  char_str() (which returns a buffer convertible to char*) or wchar_str()
  (which returns a buffer convertible to wchar_t*). These methods are
  available in wxWidgets 2.8 series beginning with 2.8.4 as well.

- The value returned by wxString::operator[] or wxString::iterator cannot be
  used in switch statements anymore, because it's a class instance. Code like
  this won't compile:
     switch (str[i]) { ... }
  and has to be replaced with this:
     switch (str[i].GetValue()) { ... }

- Return type of wxString::c_str() is now wxCStrData struct and not
  const wxChar*. wxCStrData is implicitly convertible to const char* and
  const wchar_t*, so this only presents a problem if the compiler cannot
  convert the type. In particular, Borland C++ and DigitalMars compilers
  don't correctly convert operator?: operands to the same type and fail with
  compilation error instead. This can be worked around by explicitly casting
  to const wxChar*:
     wxLogError(_("error: %s"), !err.empty() ? (const wxChar*)err.c_str() : "")

- wxCtime() and wxAsctime() return char*; this is incompatible with Unicode
  build in wxWidgets 2.8 that returned wchar_t*.

- DigitalMars compiler has a bug that prevents it from using
  wxUniChar::operator bool in conditions and it erroneously reports type
  conversion ambiguity in expressions such as this:
     for ( wxString::const_iterator p = s.begin(); *p; ++p )
  This can be worked around by explicitly casting to bool:
     for ( wxString::const_iterator p = s.begin(); (bool)*p; ++p )

- Virtual wxHtmlParser::AddText() takes wxString, not wxChar*, argument now.

- Functions that took wxChar* arguments that could by NULL in wxWidgets 2.8.
  are deprecated and passing NULL to them won't compile anymore, wxEmptyString
  must be used instead.

- wxTmemxxx() functions take either wxChar* or char*, not void*: use memxxx()
  with void pointers.

- Removed insecure wxGets() and wxTmpnam() functions.

- Removed global GetLine() function from wx/protocol/protocol.h, use
  wxProtocol::ReadLine() instead.

- wxVariant no longer derives from wxObject. wxVariantData also no longer
  derives from wxObject; instead of using wxDynamicCast with wxVariantData you
  can use the macro wxDynamicCastVariantData with the same arguments.

- wxWindow::Next/PrevControlId() don't exist any more as they can't be
  implemented correctly any longer because automatically generated ids are not
  necessarily allocated consecutively any more. Use GetChildren() to find the
  next/previous control sibling instead.


Deprecated methods and their replacements
-----------------------------------------

- wxCreateGreyedImage() deprecated, use wxImage::ConvertToGreyscale() instead.
- wxString::GetWriteBuf() and UngetWriteBuf() deprecated, using wxStringBuffer
  or wxStringBufferLength instead.
- wxDIRCTRL_SHOW_FILTERS style is deprecated, filters are alwsys shown if
  specified so this style should simply be removed
- wxDocManager::MakeDefaultName() replaced by MakeNewDocumentName() and
  wxDocument::GetPrintableName() with GetUserReadableName() which are simpler
  to use
- wxXmlProperty class was renamed to wxXmlAttribute in order to use standard
  terminology. Corresponding wxXmlNode methods were renamed to use
  "Attribute" instead of "Property" or "Prop" in their names.


Major new features in this release
----------------------------------

- wxWidgets is now always built with Unicode support but provides the same
  simple (i.e. "char *"-tolerant) API as was available in ANSI build in the
  past.

- wxWidgets may now use either wchar_t (UTF-16/32) or UTF-8 internally,
  depending on what is optimal for the target platform.

- Events loops, timers and sockets can now be used in wxBase, without GUI.
