Having this line is not useful at all as it doesn't contain any
information and shouldn't be filled in the future as git-shortlog can
provide the information about people who changed the given file more
more reliably than consulting the comments in any case.
Keep the non-blank lines for historical purposes.
Reset the selection and avoid the assert which happened when the capture
was lost unexpectedly (e.g. due to switching to another window using
some key combination without releasing the mouse).
wxOSX already does it, so do it in wxMSW too for consistency and because
it seems useful to be able to react to the same event in all cases.
Update the drawing sample to refresh its system colours scheme whenever
the theme is changed.
This allows to determine if dark mode is enabled (for the applications
and/or the system UI itself, respectively) system-wide which is useful
now that IsDark() returns false unless MSWEnableDarkMode() is called.
Also document the incompatible change to IsDark().
Adjust scrolled contents for screen drawing directly in EVT_PAINT
handler instead of doing so conditionally for generic wxDC.
This also helps demonstrating if wxPaintDC transformations
are transferred properly to wxGCDC.
This is a combination of running clang-tidy with modernize-use-nullptr
check for some ports (GTK, X11, OSX) and manual changes to the ports for
which it couldn't be used easily (MSW, DFB) and also manually updating
the docs.
Also replace NULL with null or nullptr in the comments as this is more
consistent with the use of nullptr in the code and makes it simpler to
grep for the remaining occurrences of NULL itself.
And also use null in the assert messages.
Only a few occurrences of "NULL" are still left in non-C files, mostly
corresponding to unclear comments or string output which it might not be
safe to change.
This port hasn't been updated for ages and is not used by anybody any
longer, so remove its code to facilitate maintenance.
Also remove references to this port from the documentation and most of
the other places (VMS-specific descrip.vms files still check for it
because it's not clear how to update them all), including configure.
Regenerate the latter and rebake all makefiles.
Finally document that this port is not available any longer.
Don't use FromDIP for 0.
Include DIP in drawing sample variable and function names to make it clear these sizes are in DIP.
Show both logical and DIP coordinates in statusbar.
wxBitmap::CreateWithDIPSize expects an DPI independent size.
And when saving as SVG, it also expects a DPI independent size.
Also show DPI independent coordinates in the status bar.
This reverts most of the changes from ee2b02614e (Add GetDPIScaleFactor to wxDC
and wxGraphicsContext, 2022-04-16).
This is not supposed to be used to scale pixels, FromDIP will be added instead.
Temporary use scale=1 in the drawing sample until FromDIP is added.
Apply it manually because MSW doesn't do it automatically for us and
also adjust the font size in wxMemoryDC as the base class version only
does it for the device contexts associated with a window, but we also
need to do it when using a wxMemoryDC for a bitmap using scale factor
different from that of the main display.
As the result of these changes, contents drawn on wxMemoryDC, both
directly via its own methods, or via wxGraphicsContext (using either
GDI+ or Direct2D) created from it, it appears the same as in wxWindowDC
(e.g. wxPaintDC) created for a window using the same scale.
Closes#22130.
Closes#22234.
Remove support for Borland C++ compiler, it wasn't tested since a long
time and probably didn't work anyhow and there was no interest in
keeping support for it since many years.

This has the disadvantage of not using the same accelerators in
different wxWidgets builds, but the advantage of appearing logical to a
casual user when running the sample, while having "0, 1, 3, 4" sequence
was surprising.
Alternatively, we could always add all menu items, but disable the ones
that are not available in the current build. It could be surprising to
see "GDI+" under non-MSW systems too though.
Make "Use default wxGraphicsContext" part of the renderer selection
radio group and put it in correct order, as having "1, 0, 3, 4"
accelerators order in the menu was really surprising.
Remove wxEVT_UPDATE_UI handlers as they complicated things in the sample
code (which is supposed to be simple, after all) without much benefit
and arguably even added to the confusion during run-time as menu items
could both be manually selected and checked automatically.
This adds a demonstration of drawing with affine 2D transformation applied
to wxDC. Transformation paramaters (translation, scale, rotation angle)
can be set/reset with new menu "Transformation".
Provide a way to retrieve the name of the current system appearance
(mostly for diagnostic purposes) and check if it uses predominantly dark
colours.
Currently this class has a non-trivial (but still very simple)
implementation under macOS only and simply checks whether the default
text colour is brighter than the default background colour under the
other platforms, but other platform-specific implementations could be
added later.
Also update the drawing sample "system colours" page to show the system
appearance as well.
Add the handler earlier, as creating the handler main frame uses
wxArtProvider::GetBitmap() which can add the PNG handler on some
platforms (e.g. macOS, when using wxTangoArtProvider), so calling
wxImage::AddHandler() again after creating the frame could result in a
debug error message about adding the same handler twice.
Pass wxStrings directly to wxString::Format("%s") and similar
pseudo-vararg functions, there is no need for c_str() there since
wxWidgets 2.9.

The use of wxS() is an optimization which can be used to avoid an
implicit conversion from narrow to wide strings, but such optimizations
are not really needed in the samples and just make their code less
readable, so remove them.
Closes https://github.com/wxWidgets/wxWidgets/pull/956
When using an out of source build, the files are not in the default wxWidgets directories.
Also search in the current directory, parent directory and sample sub-directories.
Closes https://trac.wxwidgets.org/ticket/18118
Advanced gradients are drawn using wxGraphicsContext and hence bounding box for underlying wxDC is not updated automatically. We need to update bounding box with extents of all used graphics paths.
Determine actual size of drawing area and use it (instead of virtual size of the window) as a dimension of the images to be saved. Thanks to this clipping, produced images contain only results of drawing operations and not lot of empty background space.
