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 and contrib libraries 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. + +Also the "applet", "deprecated", "fl", "mmedia" and "plot" contrib libraries +were removed as they were unmaintained and broken since several years. +The "gizmos", "ogl", "net" and "foldbar" contribs have been moved to +wxCode (see http://wxcode.sourceforge.net/complist.php); they are now +open for futher development by volunteers. + +The "stc" and "svg" contribs instead have been moved respectively into a new +"official" library stc and in the core lib. + + 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.
