This function can be used to check if drawing on wxClientDC actually
works. This has to be a run-time, rather than compile-time, check
because in wxGTK3 this depends on the backend being used: wxClientDC
only doesn't work with Wayland, but does work with X11 (and, less
importantly, Win32) backend(s).
Currently the wxWindow parameter of this function is not used but it
could be useful in the future and it will be simpler to allow not
specifying it (by defaulting it to nullptr) than to add it later, so it
seems better to have it.
Destroying clipping region is since 106b850593
("Fix wxCairoContext::ResetClip() for wxGTK", 2022-10-28) fully handled in
parent wxGCDCImpl::DestroyClippingRegion() calling wxCairoContext::ResetClip()
(including re-establishing clip for paint update area) so there is no need
to implement overriding method in wxPaintDCImpl.
Closes#23046.
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.
No real changes, just clean up sources by removing trailing spaces from
all the non-generated files.
This should hopefully avoid future commits mixing significant changes
with insignificant whitespace ones.
This allows to avoid initializing the variables to 0 in all the
overloaded ctors: wxSize default ctor already does it.
It's also more convenient to use GetScaledSize() rather than assigning
m_width and m_height separately, even if the rest of the code is broadly
unchanged.
We can reuse another ctor taking wxWindow* instead. Although this does
require an ugly cast, it's more explicit than just passing 0 which
could, in principle, match both the ctor taking wxWindow* and another
one taking double, and so is still preferable.
This is similar to the previous commit and is done for the same reasons:
screen DC needs to use the same DPI as the screen itself, instead of the
default Cairo 72 DPI.
For wxDC associated with a window, such as wx{Window,Client,Paint}DC,
this method should return the window PPI, not the hard coded 72 DPI of
Cairo graphics context.
This still doesn't work correctly when using multiple monitors with
different DPI settings, but is still a (modest) improvement.
This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.
If nothing else, this will make an eventual transition to Git simpler.
Closes#14487.

Even though most compilers just ignore this, it's just wrong and if you
do get warnings about header files, they can become quite overwhelming.

and thus removed all the duplicated code in all wxDC
classes.
Problematic is that wxSVGFileDC and wxPostscriptDC inherit
from wxDC and therefore include platform specific code
(also before this change) so I chose to override all
SetLogicalOrigin() etc. methods in these classes and
call their wxDCBase methods thereby circumventing the
platform dependent code.
I'm afraid the Mac code will require updating, too.

virtual and implement them like any other method
in the wxDC classes, not only in the their files
but somehow belonging to the wxDCBase class.
This is required for plugging in differnt DC backends
with different conversions.
Ideally (and absolutely possible ) all these methods
should be removed and just the one in wxDCBase
should stay using values set in the various
derived classes.
