Drawing on a wxBitmap via wxMemoryDC modified its pixmap representation in
wxGTK and even if its pixbuf representation was later changed using direct
access to the bitmap pixels, the out of date pixmap continued to be used,
creating the illusion of direct access being completely ignored.
Fix this by purging the old pixmap representation when locking the bitmap for
raw access.

The code could crash if m_overflowVisible was true but m_overflowSizerItem was
NULL. Ideally this shouldn't happen in the first place, but it did, so at
least fix the crash for now -- and hopefully this code will be refactored to
make it more clear later.

Generalize the code in wxTopLevelWindowBase dtor checking for the children of
the TLW being destroyed pending for deletion themselves to work when the child
TLW is an indirect child, i.e. was created with a child window of this TLW as
parent and not this TLW itself.

Under this system vsscanf() is declared as taking a non-const char* as first
argument which prevented our code using it from compiling. Wrap it in
wxCRT_VsscanfA() adding the necessary const_cast<> to fix this.

Subsequent calls didn't initialize the hidden window correctly because
wxSocket::Shutdown() unregistered the window class used for it, but
wxSocket::Initialize() still kept a pointer to the previously registered class
name.
Don't remember it any longer, unlike in the other cases where we use
wxCreateHiddenWindow(), this function is only ever going to be called once
until the class is unregistered anyhow, so it doesn't have to be static.

Use wxUIntPtr, not long, and SetItemPtrData() instead of SetItemData(), to
ensure that we preserve the values of client data pointers in 64 bit build,
otherwise they were truncated to 32 bits.

We multiplied the number of items by the size of each element twice, once in
wxVector::reserve() itself and once in Ops::Realloc() it called, so we
allocated much more memory than actually needed.
Fix this by passing the number of elements to Ops::Realloc().

This is important not only for consistency with the other platforms but also
because without SIZEOF_LONG_LONG being defined, "%lu" format specifier can't
be used with size_t values under Win64, as Arg_Size_t is not defined correctly
there if SIZEOF_LONG_LONG is unknown.

We didn't repaint the owner drawn combobox items any more because they were
not found by MSWFindItem().
Fix this by restricting the check to the real windows with the same ID as the
combobox, not the dropdown items which are not windows at all.

The recent changes to mouse wheel scrolling broke it for the generic
wxListCtrl and probably any other situation in which scrollbars don't scroll
the window itself but some subwindow of it. In this case, the scroll wheel
event handler doesn't have any scrollbar to adjust, so it simply does nothing
and shouldn't return true, as it did since r74911.
Just return false in case we are not doing anything to let the mouse wheel
work as before.

We detected that the label was invalid and gave a debug warning message about
it but then still proceeded to crash by accessing the data beyond the end of
the string. Don't do this.
Closes#15665.

If a wxComboBox was created with ID=1000, clicking in its drop down didn't
work.
It turns out that the native combobox control always creates its dropdown
listbox with the ID of 1000 and that when we were getting LBN_SELCHANGE from
it we mishandled this message because our code mistakenly believed that all
messages from the ID of the control itself were, in fact, coming from this
control, which wasn't the case here.
Fix this by adding a special check for this case in wxComboBox. Also
virtualize the dynamic cast which was done in wxWindow::FindItem() as this
makes the code simpler and allows to get rid of __WXUNIVERSAL__ #ifdef as
well.
Closes#15647.

Avoid conflict between wxMSW symbol defined in wx/platinfo.h in this build
configuration and wxMSW namespace by renaming the latter to wxMSWImpl, which
is also consistent with the namespace name used elsewhere.
Closes#15624.

This ensures that the files created by wxTextCtrl::SaveFile() can be read back
by wxTextCtrl::LoadFile() as previously the files were saved using the current
locale encoding but read back using Latin1 (after first trying, and failing,
to read them as UTF-8).
This is a backwards incompatible change but it ensures that wxTextCtrl can
load its own files and is also consistent with the use of UTF-8 by default in
other places. Finally, and perhaps most importantly, this ensures that the
file contents can always be saved, i.e. there is no risk of conversion errors
any more.
Closes#15611.

It didn't count the angles correctly when they were equal to 90 degrees.
Also simplify the code by avoiding special cases for 90 degrees anyhow, just
call atan2() directly. And also avoid converting the angles to degrees just to
convert them back to radians immediately afterwards.

We must use wxUIntPtr and not long here to avoid truncating the upper half of

While we can't change the type of wxVariant to which SAFEARRAYs are converted
by default, it's much more convenient to work with the variant objects of the
correct type, i.e. using wxVariantDataSafeArray, when dealing with SAFEARRAYs,
so add a flag which can be set to tell a wxAutomationObject to behave in this
way.

This allows the program to distinguish between some other, unspecified,
warnings and this one which can and does happen whenever too many changes
occur too quickly but which has a clearly defined work around: the state kept
inside the program just needs to be refreshed by rescanning the directory anew.

Explicitly use wxConvLibc with wxTextInputStream to make sure we correctly

The GetUntranslatedString() hack keeps a global copy of all strings, so
that it can return a const reference as wxGetTranslation() return value.
A global wxHashSet instance shared by all threads won't do, even guarded
with a critical section, because it may internally copy values on any
insert and thus invalidate pointers that may still be used on another
thread.

Always move the dates invalid due to DST (i.e. falling into the "missing" hour
on the DST start date) forward, as GNU libc does, even when using a different
CRT implementation, such as MSVC one which moves the invalid dates backwards.
This seems more expected and also fixes an especially bad problem which
happened due to moving the date backwards in Brazilian time zone where DST
starts at midnight as doing this changed the day and totally broke ParseDate()
assumption that setting wxDateTime to 00:00:00 at the given date really did
set it to this date.
