wxPropertyGrid::ExpandEscapeSequences() function should convert all valid
escape sequences (\r, \n, \t, \\) to the corresponding single characters
(CR, LF, TAB, backslash, accordingly) and
wxPropertyGrid::CreateEscapeSequences() function should do the reverse
operation and convert these raw characters to the corresponding escape
sequences.
Closes#17896.
Ensure that the restored size is at least equal to the best size of the
window to avoid cutting off parts of it in (a common) case when a newer
version of the program adds new UI elements, thus increasing the window
best size and possibly making the previously stored size too small.
Creating a font with wxFONTSTYLE_SLANT results in a font whose
GetStyle() returned wxFONTSTYLE_ITALIC, so it was never found in the
cache, resulting in, effectively, leaking memory and GDI handles because
each new call to wxFontList::FindOrCreateFont(...wxFONTSTYLE_SLANT)
created a new font.
Fix this by just hardcoding that wxFONTSTYLE_SLANT is wxFONTSTYLE_ITALIC
under MSW, this is ugly but avoids backwards incompatible (and not
obviously correct) change of making wxFont::GetStyle() return
wxFONTSTYLE_SLANT if the font was created using this style.
Notice that wxFont::GetStyle() does behave like this in wxOSX currently,
so there is an inconsistency between ports here. It would arguably be
better to make wxOSX behave like wxMSW because the actual font is really
italic and not slant/oblique and if we do this, the preprocessor
condition in this commit should be extended to cover wxOSX too.
Closes#17903.
The logic in wxButton::{Set,Unset}TmpDefault() didn't work at all when
the temporary button was the same as the permanent default button as the
code made the same button non-default immediately after making it
default (or vice versa). In particular, this ensured that default button
was never highlighted correctly (at least after the first focus change)
in dialogs containing a single button only.
Fix this by simply skipping modification of the old default button if it
was the same one as the new default button.
This feature to show/hide alpha values and opacity selector (slider) is
already implemented under wxGTK and for generic wxColourDialog.
For the sake of backward compatibility, this feature is enabled here by
default (through the corresponding property of wxColourData).
Currently region given in device coordinates is decomposed into the stripes which are next transformed to the logical coordinates required by underlying wxGraphicsContext::Clip() function. Some of these stripes given in device coordinates can have 1-pixel height what after transformation to logical coordinates can give zero-height stripes (after rounding). This can lead to the situation that in the region transformed to logical coordinates some stripes can disappear and final transformed region shape is different from the source shape (it has gaps).
To fix this issue device coordinates of the region are not manually transformed to the logical coordinates but instead wxGraphicsContext's is temporarily set to the state where its logical coordinates are equivalent to device coordinates and thus clipping region can be applied directly.
Solution for wxMSW, wxGTK is implemented in ea8cb7a24a.
Closes#17609.
Transformation settings already applied to the source objects (CGContext, wxWindow) and inherited by wxGraphicsContext should be considered as a baseline transformation matrix for wxGC and shouldn't be exposed through e.g. GetTransform() function (like it's done in Cairo or Direct2D). To report only transformations explicitly applied to wxGC by calls to the corresponding wxGC functions, we need to store initial CTM (in a dedicated variable) and "subtract" it from the actual transformation settings.
See #17609.
Member data containing clipping box have to be updated not only when the clipping region is explicitly changed by SetClippingRegion()/DestroyClippingRegion() but also when existing wxGraphicsContext is associated with wxGCDC using SetGraphicsContext() or when wxGCDC coordinates are transformed with SetDeviceOrigin(), SetLogicalOrigin(), SetUserScale() or SetLogicalScale().
When any of these functions is called then clipping box data are marked as invalid and retrieved from underlying graphics context using wxGraphicsContext::GetClipBox() at nearest call to GetClippingBox().
Solution for wxMSW, wxGTK was implemented in 98714ea452.
See #17646.
Rename relatively new enum value wxTASKBAR_JUMP_LIST_DESTIONATION to
wxTASKBAR_JUMP_LIST_DESTINATION as well as a private function containing
the same typo.
Even though this function was private and not available in the default build
(in which wxUSE_OLE==1, while this function was only defined with
wxUSE_OLE==0), still mention its removal for completeness.
Handle "bitmap" and "bitmapposition" attributes in wxToggleButton XRC handler,
just as it's already done for wxBitmap and wxBitmapToggleButton.
Closes#17850.
Dedicated wxDataObject::SetData() function can be used to import raw
clipboard data to the corresponding instances of wxDataObject and hence
there is no need to duplicate data retrieval code.
When CF_DIB object is placed to the clipboard, a handle to the memory
object containing a BITMAPINFO structure followed by the bitmap bits should
be passed to SetClipboardData(), not a handle to a DIB section.
Also, wxClipboard is the owner of the wxDataObject being added, so it
should release passed object.
Not all applications recognize properly 0RGB bitmap format so for the sake
of interoperability bitmaps in such format should be converted to plain
24 bpp RGB format prior to being copied to the clipboard.
Closes#17640.
In wxRearrangeList implementations (like wxMSW) where DoInsertItemsInLoop()
and DoInsertOneItem() are not used to insert multiple items, DoInsertItems()
has to be overriden to do this insertion.
See #17836.
Labels containing mnemonic prefixes (&) and literal underscore characters
have to be converted to the proper GTK labels where underscore
characters act as mnemonic markers. If label contains mnemonic then
dedicated function gtk_radio_button_new_with_mnemonic() should be used
to create radio button item.
Closes#17419.
Don't apply at best unnecessary, and actually harmful, as it uses a wrong
conversion, fn_str() when calling wxRmDir() which takes wxString.
Update unit tests to check that wxRmdir() now works with non-ASCII filenames
too.
Closes#17644.
Assert and return false instead, this is more developer-friendly.
Add unit tests to check that these functions really work as expected when
called on a closed file.
Closes#17828.
Draw pie, not arc, if current brush is not transparent.
Also simplify the code by invoking PostScript 'arc' operator only once if pie is drawn.
Closes#17805.
PostScript code to register (and re-encode) given font should be emitted only once. Once registered, the font is available in the entire document and there is no need to register it again.
Add wxCMD_LINE_HIDDEN wxCmdLineParser flag allowing to hide options and/or
parameters.
A hidden/unlisted argument is processed as usual, but not shown in the output
given by Usage(). A use case for such could be diagnostics switches that
should exist but are not useful to the end user.

EVT_STC_KEY and EVT_STC_URIDROPPED events are never generated so there is no need to reference them in the code and documentation. For backwards compatibility reasons their declarations are not entirely removed but marked as deprecated.
Closes#17688.
While we have to keep these conversions enabled by default, they are very
dangerous as they can result in silent data loss on any system not using a
locale with UTF-8 encoding, i.e. always under MSW.
Allow mitigating this by defining wxNO_UNSAFE_WXSTRING_CONV when compiling the
application code using the library, which makes these conversions invisible to
the user code, and so can be used without recompiling the library.
Also add wxUSE_UNSAFE_WXSTRING_CONV which can be set to 0 when compiling the
library to disable these conversions globally for all applications using it.
Closes#11830.
Draw underline relatively to the baseline and obtain line parameters using 'stringwidth' operator instead of calculating them manually based on the parameters returned by DoGetTextExtent(), which are not always accurate (e.g. if no AFM files are available).
Closes#17788.
Legacy API cairo_win32_surface_create() can create only 24 bpp RGB surfaces but new API cairo_win32_surface_create_with_format() introduced in 1.15.4 supports creating also 32 bpp ARGB surfaces.
So, this new API can be used to create ARGB surface directly from ARGB bitmap (HDC), superseding current implementation based on the access to the bitmap data with cairo_image_surface_create_for_data().
Unfortunately, 0RGB bitmaps are not supported by cairo_win32_surface_create_with_format() and for such bitmaps surface has to be still created from bitmap data.
VC++ compilers (at least up to VS 2015) seem to generate incorrect code for the dithering code taken from libjpeg (pass2_fs_dither() function), where it is known to create problems too.
Refactor the code to avoid invalid optimization in this function and turn optimization on.
Closes#17764.
Using "%20c" in scanf() doesn't work unless we really have exactly 20
characters, so use "%20[^)]" to take up to 20 characters until the closing
parenthesis instead.
Closes#17739.
Using Bind() with a method of the class deriving from wxEvtHandler
non-publicly used to result in a compile-time error, but at least with C++11
we can detect this case and allow the code to compile.
Closes#17623.
The native EDIT control doesn't handle this key combination, but RICHEDIT does
and people just expect it to work, so handle it at wxMSW level.
