INCOMPATIBLE CHANGES SINCE 2.8.x
================================
+
+ Notice that these changes are described in more details in
+ the "Changes Since wxWidgets 2.8" section of the manual,
+ please read it if the explanation here is too cryptic.
+
+
Unicode-related changes
-----------------------
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:
+ either "const wxString&" (so that they accept both Unicode and ANSI strings;
+ the argument can't be NULL anymore in this case) or "const char *" (if the
+ strings are always ANSI; may still 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
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.
+ Also notice that connection classes should change the parameter types of
+ their overridden OnExecute() or override a more convenient OnExec() instead.
-wxODBC library removal
-----------------------
+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!
---------------------------------------------------------------------------
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.
+
+- wxCalendarCtrl has native implementation in wxGTK, but it has less features
+ than the generic one. The native implementation is used by default, but you
+ can still use wxGenericCalendarCtrl instead of wxCalendarCtrl in your code if
+ you need the extra features.
+
+- wxDocument::FileHistoryLoad() and wxFileHistory::Load() now take const
+ reference to wxConfigBase argument and not just a reference, please update
+ your code if you overrode these functions and change the functions in the
+ derived classes to use const reference as well.
+
+- Under MSW wxExecute() arguments are now always properly quoted, as under
+ Unix, and so shouldn't contain quotes unless they are part of the argument.
+
+- wxDocument::OnNewDocument() doesn't call OnCloseDocument() any more.
+
Changes in behaviour which may result in compilation errors
-----------------------------------------------------------
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() : "")
+- Return type of wxString::c_str() is now a helper wxCStrData struct and not
+ const wxChar*. wxCStrData is implicitly convertible to both "const char *"
+ and "const wchar_t *", so this only presents a problem if the compiler cannot
+ apply the conversion. This can happen in 2 cases:
+
+ + There is an ambiguity because the function being called is overloaded to
+ take both "const char *" and "const wchar_t *" as the compiler can't choose
+ between them. In this case you may use s.wx_str() to call the function
+ matching the current build (Unicode or not) or s.mb_str() or s.wc_str() to
+ explicitly select narrow or wide version of it.
+
+ Notice that such functions are normally not very common but unfortunately
+ Microsoft decided to extend their STL with standard-incompatible overloads
+ of some functions accepting "const wchar_t *" so you may need to replace
+ some occurrences of c_str() with wx_str() when using MSVC 8 or later.
+
+ + Some compilers, notably Borland C++ and DigitalMars, 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*.
- Virtual wxHtmlParser::AddText() takes wxString, not wxChar*, argument now.
-- Functions that took wxChar* arguments that could by NULL in wxWidgets 2.8.
+- 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.
- 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.
necessarily allocated consecutively any more. Use GetChildren() to find the
next/previous control sibling instead.
+- Calling wxConfig::Write() with an enum value will fail to compile because
+ wxConfig now tries to convert all unknown types to wxString automatically.
+ The simplest solution is to cast the enum value to int.
+
+- Several wxImage methods which previously had "long bitmaptype" parameters
+ have been changed to accept "wxBitmapType bitmaptype", please use enum
+ wxBitmapType in your code.
Deprecated methods and their replacements
-----------------------------------------
- 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.
+- wxConnection::OnExecute() is not formally deprecated yet but new code should
+ use simpler OnExec() version which is called with wxString argument
+- wxMenuItem::GetLabel has been deprecated in favour of wxMenuItem::GetItemLabelText
+- wxMenuItem::GetText has been deprecated in favour of wxMenuItem::GetItemLabel
+- wxMenuItem::GetLabelFromText has been deprecated in favour of wxMenuItem::GetLabelText
+- wxMenuItem::SetText has been deprecated in favour of wxMenuItem::SetItemLabel
+- wxBrush's, wxPen's SetStyle() and GetStyle() as well as the wxBrush/wxPen ctor now take
+ respectively a wxBrushStyle and a wxPenStyle value instead of a plain "int style";
+ use the new wxBrush/wxPen style names (wxBRUSHSTYLE_XXX and wxPENSTYLE_XXX) instead
+ of the old deprecated wxXXX styles (which however are still available).
+- EVT_CALENDAR_DAY event has been deprecated, use EVT_CALENDAR_SEL_CHANGED.
+- EVT_CALENDAR_MONTH and EVT_CALENDAR_YEAR events are deprecated,
+ use EVT_CALENDAR_PAGE_CHANGED which replaces both of them.
+- wxCalendarCtrl::EnableYearChange() and wxCAL_NO_YEAR_CHANGE are deprecated.
+ There is no replacement for this functionality, it is being dropped as it is
+ not available in native wxCalendarCtrl implementations.
+- wxDC::SetClippingRegion(const wxRegion&) overload is deprecated as it used
+ different convention from the other SetClippingRegion() overloads: wxRegion
+ passed to it was interpreted in physical, not logical, coordinates. Replace
+ it with SetDeviceClippingRegion() if this was the correct thing to do in your
+ code.
+- wxTE_AUTO_SCROLL style is deprecated as it's always on by default anyhow.
Major new features in this release
- 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 and timers can now be used in wxBase, without GUI.
