Don't use the child window of the desktop window for popup windows under
MSW, while this worked in simplest cases, it didn't allow having
functional controls inside a wxPopupWindow as e.g. wxTextCtrl didn't
accept input it at all if created as a child of such window.
Instead, switch to using a top-level window, with WS_POPUP style, and
fix the problem with the loss of activation by explicitly pretending to
still be active in the owner window when losing activation to our own
popup (thanks to Barmak Shemirani for providing this solution).
Also use an MSW-specific and much simpler implementation of detecting
when the popup should be dismissed in wxPopupTransientWindow: instead of
capturing mouse or tracking focus, just react to activation loss
directly.
Add a wxTextCtrl to the popup in samples/popup to show that editing it
works now.
IsTopLevel() returns true for wxPopupWindow, even if it's not a subclass
of wxTopLevelWindow, so GetTLWParentIfNotBeingDeleted() asserted when
called with a button inside a wxPopupWindow.
Just return null from it instead for now. A better solution could be to
return wxNonOwnedWindow from GetTLWParentIfNotBeingDeleted() (which
would need to be renamed to something more suitable) and move the
{Get,Set}TmpDefaultItem() methods into it.
wxString is not implicitly convertible to const char* in that configuration.
Also, stock IDs work fine with GTK+3 despite being deprecated, so only avoid
them for GTK+4.
Now that wxSound class, which can optionally use SDL, is in wxCore, we
need to link it with the SDL libraries to fix link errors in this case.
Closes#18251.
Using font height to determine required height of wxStaticText control used to display a title is not sufficient because this doesn't take into account internal margins, borders etc. around displayed text within the control. Because this internal positioning depends on the port it's better to delegate calculation of the required height to the control itself.
Closes#17662.
Currently all properties within client area are processed for drawing whether they lie inside the update region or not. Processing for drawing is an expensive operation so doing this only for properties being actually repainted should improve performance.
Change GTKGetEntryTextLength() to return a signed value, as it's always
either assigned to or compared with the signed variables anyhow.
This avoids a couple of -Wsign-compare warnings when building with g++
5.4 from Ubuntu 16.04.
Instead of running normally under some platforms and crashing under MSW
(when using themes) when passing NULL to GetCheckBoxSize(), now
consistently assert and return zero size everywhere.
Closes#18241.
