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). + + + 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. + 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 +- 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. + + 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 ---------------------------------- @@ -30,6 +138,36 @@ Major new features in this release All: +- Added support for user-defined types to wxConfig (Marcin Wojdyr). +- Added wxJoin() and wxSplit() functions (Francesco Montorsi). +- Added wxMutex::LockTimeout() (Aleksandr Napylov). +- Added wxMemoryInputStream(wxInputStream&) ctor (Stas Sergeev). +- Implemented wxMemoryInputStream::CanRead(). +- Added wxEXEC_BLOCK flag (Hank Schultz). +- Add support for wxStream-derived classes to wxRTTI (Stas Sergeev). +- Added wxStreamBuffer::Truncate() (Stas Sergeev). +- Allow using wxEventLoop in console applications (Lukasz Michalski). +- Added functions for Base64 en/decoding (Charles Reimers). +- Added support for binary data to wxConfig (Charles Reimers). +- Added functions for atomically inc/decrementing integers (Armel Asselin). +- wxLogInterposer has been added to replace wxLogPassThrough and new + wxLogInterposerTemp was added. +- Added support for broadcasting to UDP sockets (Andrew Vincent). +- Documentation now includes the wx library in which each class is defined. + +All (Unix): + +- Added wx-config --optional-libs command line option (John Labenski). + +All (GUI): + +- Added wxH[V]ScrolledWindow (Brad Anderson, Bryan Petty). +- Added wxDC::StretchBlit() for wxMac and wxMSW (Vince Harron). +- Added support for drop down toolbar buttons (Tim Kosse). +- Added support for labels for toolbar controls (Vince Harron). +- Added wxMessageDialog::SetMessage() and SetExtendedMessage(). +- Added XRCSIZERITEM() macro for obtaining sizers from XRC (Brian Vanderburg II) +- New and improved wxFileCtrl (Diaa Sami and Marcin Wojdyr) - Added wxEventBlocker class (Francesco Montorsi). - Added wxFile/DirPickerCtrl::Get/SetFile/DirName() (Francesco Montorsi). - Added wxSizerFlags::Top() and Bottom(). @@ -37,33 +175,168 @@ All: - Fixed tab-related drawing and hit-testing bugs in wxRichTextCtrl. - Implemented background colour in wxRichTextCtrl. - Fixed crashes in helpview when opening a file. -- Added wxMutex::LockTimeout() (Aleksandr Napylov) -- Set locale to the default in all ports, not just wxGTK +- Set locale to the default in all ports, not just wxGTK. +- Added wxJoystick::GetButtonState/Position() (Frank C Szczerba). +- Added wxGridUpdateLocker helper class (Evgeniy Tarassov). +- Support wxGRID_AUTOSIZE in wxGrid::SetRow/ColLabelSize() (Evgeniy Tarassov). +- Added wxWindow::NavigateIn() in addition to existing Navigate(). +- Add support for tags to wxrc. +- Support wxAPPLY and wxCLOSE in CreateStdDialogButtonSizer() (Marcin Wojdyr). +- Show standard options in wxCmdLineParser usage message (Francesco Montorsi). +- Added wxRect::operator+ (union) and * (intersection) (bdonner). +- Added support for two auxiliary mouse buttons to wxMouseEvent (Chris Weiland). +- Added wxToolTip::SetAutoPop() and SetReshow() (Jan Knepper) +- Added wxTaskBarIcon::Destroy() +- Added XRC handler for wxSearchCtrl (Sander Berents) +- Read image resolution from TIFF, JPEG and BMP images (Maycon Aparecido Gasoto) +- Add support for reading alpha data from TIFF images +- Added wxSYS_DCLICK_TIME system metric constant (Arne Steinarson) +- Added wxApp::Get/SetAppDisplayName() (Brian A.
