RefreshRow() is called very frequently, and in particular after every
ItemChanged notification. Calling GetEndOfLastCol() in it repeatedly is
extremely inefficient in presence of auto-sizing columns, and doesn't
make much sense anyway - controls with significant space unoccupied by
columns are rare, and rendering of such unused space is efficient (just
background erase). It is therefore more performant to simply refresh
the entire row instead of repeatedly and expensively calculating the
smallest rectangle that needs repainting.
Fixes previously wrong calculation of the refreshed rectangle in
RefreshRows() in the process.
Fixes major performance regression introduced in
77c7c80696.

Cache labels for "Next>" or "Finish" button in wxWizard so that their
translations stay consistent throughout wizard's lifetime: previously,
this button could use a label in a different language if the currently
used translations have changed since the wizard creation, as this label
was recreated on every page change, unlike the other labels which were
only translated once in the very beginning.

If we can't determine the display-specific PPI value, use the global one
which seems to be always available (and always equal to 96*96 in my
testing -- but this is what previous versions of wxWidgets returned, so
it's still better than nothing).
Under macOS colors can be patterns, then accessors for RGB values are useless, IsSolid returns true if the color can be expressed in RGB values at all.
Get rid of wxOSX wxImageList implementation as it was 99% identical to
the generic version and the non-identical parts should really have been
made part of the generic version too from the beginning.
Notably, use GetScaled{Width,Height}() in Add() method in the generic
version too now.
This is not necessary as wxIcon is implicitly convertible to wxBitmap
anyhow, so calling Add(icon) works using the existing Add(wxBitmap)
overload, and is actually harmful because of the wrong icon size check
in this function, which used physical bitmap size instead of the logical
(scaled) size.
Closes#18188.
These functions combine the sizes of all displays and so only return the
correct size when there is only a single display.
This fixes wildly wrong PPI values returned when more than one display
is used.
We need to account for the scale factor under GTK+ (and, presumably,
under macOS) to compute the correct PPI value as it must use the number
of physical and not logical pixels.
Reimplement wxCheckOsVersion() to use wxGetOsVersion() on windows.
An executable without the Windows 8.1+ compatibility info in a
manifest would not detect the version based on the VerifyVersionInfo()
API previously used.

Surprisingly, ::SuspendThread() doesn't actually do it, but only
schedules the thread for suspension in some undetermined near future.
This could result in problems as Pause() could exit, releasing the CS
protecting wxThread internal data in the main thread, and allowing the
worker thread to enter it (e.g. in its TestDestroy()) before being
actually suspended, meaning that the thread got suspended inside a CS,
which resulted in later deadlocks.
Fix this by calling ::GetThreadContext() which is supposed to ensure
that the scheduler does really suspend the thread before it returns (as
it's impossible to get the context of a thread while it's running).
Closes#18137.
Reimplement wxPopupWindow using WS_POPUP instead of WS_CHILD window in
wxMSW as the new approach allows using the controls inside the popup
normally, unlike the old one.
See https://github.com/wxWidgets/wxWidgets/pull/986Closes#18243.
This will just hide the window immediately, so prefer to ignore the
"focus" argument of Popup() but show the popup instead.
Update the documentation to mention that setting focus outside of popup
is not supported under all platforms.
This fixes another bug from 3518f1a7d8
(after the one fixed in 5766280311): if a
window was maximized by user and then hidden, its IsMaximized() returned
false because it examined m_showCmd which didn't have SW_MAXIMIZE value
in this case.
The same was true for IsMinimised() as well.
Fix both problems by updating the value of m_showCmd when hiding the
window.
InformFirstDirection() is required to let wxWrapSizer calculate its best
height from its current width (or vice versa, but usually in this
sense), but it only worked if wxWrapSizer was an immediate child of
another size doing layout but not if wxWrapSizer was inside another
wxBoxSizer which was contained in a top-level sizer.
Explicitly forward calls to InformFirstDirection() to wxBoxSizer
children to fix this and make wxWrapSizers nested in wxBoxSizer work.
Note that there are still many problems in this code, including but not
limited to:
- Doing this forwarding for the sizer minor direction only.
- Not passing the correct value of "availableOtherDir".
- Still calling InformFirstDirection() from RecalcSizes(), when it's too
late to change the min size returned by CalcMin().
- Inconsistency: wxGridSizer calls InformFirstDirection() from its
CalcMin(), wxFlexGridSizer calls it from its RecalcSizes(),
wxGridBagSizer doesn't call it at all.
All this size-in-first-direction logic really needs to be completely
reviewed, but for now at least make wxWrapSizer inside a wxBoxSizer work
as well, or as badly, as wxWrapSizer on its own.
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.
