Fix syntax error in the QueueEvent() documentation example.

Use ".", not "->", on the object.

Closes #15881.

Compilation fix for the example in wxThread documentation.

Make MyThread a friend to allow it accessing the private fields of MyFrame.

Notice that this example still remains badly written and should be ideally
entirely redone using conditions and mutexes.

See #15881.

Fix wrong variable name in the example in wxVariantDataSafeArray documentation.

avoid crash with GTK3 when deleting an item, closes #15786

Override Do{Freeze,Thaw}() instead of {Freeze,Thaw}() in wxPropGrid code.

{Freeze,Thaw}() themselves are not virtual any more, so overriding them
doesn't really work and it is unnecessary to reimplement the reference
counting already done by the base class anyhow, so override the DoXXX()
versions instead.

Closes #15877.

Fix possible crash in TAR header parsing code.

Check that the iterator is valid before using its value, otherwise the
validity check was useless.

Closes #15888.

Fix setting fonts and colours for wxToggleButton with bitmaps in wxGTK.

Apply the fixes of r54138 to wxToggleButton too, the problem of #3939 was not
specific to just plain wxButtons.

Focus generic spin control when its spin button is pressed.

This is consistent with the behaviour of the native control under MSW and GTK
and generally makes sense as otherwise focus could remain on a completely
unrelated control.

Closes #15885.

Restore correct handling of wxDocument::OnCreate() error return value.

The changes of r74515 didn't quite restore the old behaviour, the document was
still not being cleaned up if its OnCreate() simply returned false and not
threw an exception.

Do add cleanup in this code branch too, just duplicating what we in case of
exception (this duplication can't be easily avoided unfortunately).

Closes #15883.

Use AssocQueryString() instead of manual accessing registry in wxMSW.

AssocQueryString() is more reliable and should work under all Windows
versions, including Windows 8 for which our previous implementation, reading
the values directly from the registry, had some problems.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@75647 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Fix alpha channel values when using wxGCDC with wxMemoryDC in wxMSW.

Ensure that 32bpp bitmaps selected in wxMemoryDC use DIB for their internal
representation as GDI+ functions don't seem to work correctly with DDBs with
alpha channel.

Closes #13328.

Fix appearance of tools with alpha bitmaps in wxMSW wxToolBar.

Recent changes broke the handling of tools with alpha bitmaps as drawing them
on the global toolbar bitmap changes its underlying HBITMAP now, but the code
in wxToolBar didn't expect this.

Fix it by updating the HBITMAP used after every DrawBitmap() call, just in
case it changed (it doesn't cost anything to reset it if it did not).

Closes #15876.

Improve appearance of tools using bitmaps with alpha in wxMSW wxToolBar.

Use alpha in the combined toolbar bitmap if any of its tools has a bitmap
using alpha. This greatly improves the appearance of the automatically
generated disabled images for the tools with bitmaps using alpha.

See #15876.

Exclude wxMSW-specific code from compilation under other platforms.

Compilation fix after r75648, see #13328.

Use wxUSE_WXDIB in preprocessor tests.

NEVER_USE_DIB is meant to be used only in conjunction with
{SOMETIMES,ALWAYS}_USE_DIB constants, use wxUSE_WXDIB elsewhere.

This is more logical and also fixes inadvertent use of NEVER_USE_DIB before it
is defined added by the changes of r75648.

See #13328.

Work around g++ warning about comparing compatibility_iterator with NULL.

Use double negation to placate both it and MSVC, see r75445.

Ensure wxChoice reported width never becomes negative in wxMSW.

Don't set the pending size to (-1, valid-height) as it is always supposed to
be either fully valid or fully invalid (meaning there is no pending size
change).

Closes #15723.

Deal correctly with non-ASCII hostnames in wxGetFullHostName() in wxMSW.

Somewhat surprisingly, Windows can return a non-ASCII string from
gethostname(). It's not really clear what happens if the host name is not
representable in the current locale encoding at all, but at least make the
function work in case it is.

Closes #15875.

Fix exit on last TLW logic after the change of r75633.

The changes in this revision meant to prevent the closure of transient dialogs
from quitting the application (see #15880) prevented any application using AUI,
including the aui sample, from exiting as the AUI utility frames deleted
during the main frame destruction were returning false from their
IsLastBeforeExit() now.

Fix this by relaxing the check and ignoring the parent if it is already being
deleted anyhow -- in this case there is no danger of closing it accidentally.

Closes #15894.

Pass non-primitive types by const reference instead of value.

No real changes, just avoid the unnecessary copying and also make the
signatures more consistent by adding the apparently forgotten "&" in a couple
of places.

See #15893.
