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. The same issue also applies to
+ the structure fields which used to contain "const wxChar *" pointers (such
+ as wxCmdLineEntryDesc::shortName, longName and description fields) and are
+ now wxStrings: empty strings should be assigned to them instead of NULL.
+
+
+
Changes in behaviour not resulting in compilation errors, please read this!
---------------------------------------------------------------------------
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
-----------------------------------------------------------
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:
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:
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.
+
