Enable warnings for CMake builds and fix some warnings that this
exposed.
Also add wxUSE_NATIVE_DATAVIEWCTRL option and change default GTK version
to 3 for CMake too.
See https://github.com/wxWidgets/wxWidgets/pull/1825
Always set the LB_USETABSTOPS style flag to achieve behaviour more
compatible with other platforms and expand TABs to align them at tab
stops positioned at every 8 characters.
Also add MSW-specific MSWSetTabStops() method allowing to customize tab
stops.
Update the documentation and the sample to demonstrate using TABs.
Closes https://github.com/wxWidgets/wxWidgets/pull/1789
This results in a single intelligible error instead of a hundred of less
clear ones in case our code is compiled against an out of date SDK
version.
There doesn't seem to be any way to check the version directly, so just
check that the interface which hadn't been defined in the previous
version is defined now to check for it indirectly.
Creating wxPaintDC for a window outside of any wxEVT_PAINT handler
already resulted in assert failures and crash due to using the empty
wxDidCreatePaintDC stack, but the assert message was not really clear,
so improve it by stating explicitly that wxPaintDC can only be created
from wxEVT_PAINT handlers.
Also check that wxPaintDC is being created for the correct window: this
wasn't detected at all before, but could still result in a lot of grief,
so check for this too.
Finally, create a new private header with the paint data stack variable
declaration instead of using "extern" to declare it manually in wxDC
code.
This is unnecessary, we only need to update the pending focus in the
immediate parent window to prevent a wrong radio button from being
focused (and hence selected) when it regains focus, there is no good
reason at all to interfere with the focus in the grandparent (and
higher) windows.
Doing this was not only useless, but actually harmful, as it overrode
explicit calls to SetFocus() in the user code, so just stop doing it.
This also allows to avoid having 2 functions related to this and keep
just a single virtual WXSetPendingFocus() one.
Closes#18653.
Minimized windows don't seem to get any events after "Close" menu item
is selected from the system menu, so they were never actually destroyed
when closing them in this way.
Fix this by explicitly waking up the message loop after deleting the
window to ensure that the delayed destruction does happen.
Closes#18622.

Instead of checking for all text-like controls one by one in
wxCommandEvent::GetString(), call a virtual function checking for this.
This is simpler, less error-prone and faster -- at the cost of
increasing the vtbl size of all wxWindow-derived classes.
Closes https://github.com/wxWidgets/wxWidgets/pull/1696
It defaults to 1, but can be set to 0 to force using the generic version
of the control even under GTK or Mac, where the native version is used
by default.
This can, unfortunately, be useful to work around various but multiple
native control limitations.
The change of 4990515aba resulted in
(disabled by default, but which may be enabled when building
applications using wxWidgets) MSVS 2017 warning C4265 ('class' : class
has virtual functions, but destructor is not virtual), so test for clang
explicitly instead of just testing for non-gcc.
Doing this makes the checkbox unusable with the default GTK 3 theme as
the default grid background colour (white) is the same as the colour of
the check mark -- so changing the checkbox background to it makes it
invisible.
Work around this by adding a new SetTransparentPartColour() method that
can be used by wxGrid (and, in the future, user code if we decide that
this is really the best solution to this problem that we can provide) to
make the checkbox blend in with its background without actually changing
its appearance.
Sockets returned by wxSocket::Accept() are non-blocking by default and
the only way to use them safely in worker threads is by switching them
to the blocking mode by calling SetFlags(wxSOCKET_BLOCK).
However this didn't work correctly since at least 2.8 days, as turning
wxSOCKET_BLOCK on didn't unregister the socket from the event loop, with
which it had been registered on creation. Fix this by doing this now,
which ensures that the main thread doesn't get any notifications about
the socket if it's used, in a blocking way, in a worker thread.
Note that making the new socket blocking after accpeting is still pretty
inefficient and pre-creating the socket as blocking and using
AcceptWith() is still preferable, but at least it does work now.
Closes#12886.
In addition to unblocking and registering the socket, also support using
this function to make the socket blocking and unregistering it from the
event loop, if its flags include wxSOCKET_BLOCK.
This was already half-done by wxMSW, which took wxSOCKET_BLOCK presence
into account in its implementation, but not by the Unix implementation.
Now do it under all platforms, as this will be useful for switching a
previously non-blocking socket to blocking mode.
Finally, rename the function to better reflect what it really does.
See #12886.
