Fix several problems with surrogates in UTF-16-encoded wchar_t strings:
correct bugs in UTF-8 and UTF-32 conversion code and add surrogates support to
wxText{Input,Output}Stream classes.
Closes#17070.
On the platforms using UTF-16 for wchar_t we can't read nor write Unicode data
one wchar_t at a time as a single half of a surrogate character can't be
converted to or from the encoding of the stream.
To fix this, we may need to store the last wchar_t already read from the
stream but not returned yet in wxTextInputStream::NextChar() and store,
without writing it, the wchar_t passed to wxTextOutputStream::PutChar() until
the second half of the surrogate is written.
See #17070.
Since 361c6357b4 wxDataViewRenderer's
SetAttr and SetEnabled became pure virtual class methods which aren't
implemented for wxOSX/Carbon. Fix by defining the same empty stubs for
these methods as were previously present in the base class.
The added macros wxCLANG_WARNING_{SUPPRESS,RESTORE} are similar to
wxGCC_WARNING_{SUPPRESS,RESTORE}, but the `wxCLANG_' version will expand to
compiler pragmas only when the warning name is known to the compiler.
They use clang's __has_warning feature.
Added opacity slider and custom colours (with alpha) previews (implemented with wxStaticBitmap controls). This feature is controlled by wxColourData::GetChooseAlpha().
Variable to hold the size of the custom colour box doesn't need to be a member variable since it's used only locally in wxGenericColourDialog::CalculateMeasurements.
wx/control.h is already included from wx/slider.h so including it from here is
useless and including wx/slider.h is even worse as it's very confusing because
this header itself is already included from wx/slider.h.
No real changes.
Derive wxStaticBox from wxStaticBoxBase for consistency with the other ports
and to make it derive from wxNavigationEnabled<>, which is necessary for TAB
navigation to work.
Closes#3842.
The bug that resulted in creating huge DLLs that took inordinate amounts of
memory and time to link with g++ 4.5 has been fixed in 4.7, so don't export
everything when using it, as this results in even smaller DLLs.
The situation with 4.6 is unknown, so leave behaviour with it unchanged.
See 49d2c0adc3
::TlsGetValue() resets the last error code which means that the previous last
error is lost, but it shouldn't as we might be in the middle of logging it
with wxLogSysError(). So preserve the last error explicitly.
Closes#17209.
The user code may handle this event, meaning that its handler in wxNotebook
itself is never invoked, but this broke actually changing the pages.
Fix this by doing the page change in the code handling the underlying OS X
event directly.
Closes#17197.
wxSizer already has m_minSize field, use m_calculatedMinSize for the field of
the derived wxBoxSizer class to avoid confusion, just as wxFlexGridSizer
already did.
Also add a new unit test checking that GetMinSize() still works after this
change.
