Fix creating wxGLCanvas without any attributes in wxMSW.

This was broken by the changes of r77018, see #16402.

Just check that we do have the attributes before examining them.

Refactor Unix OpenGL code to avoid using static attributes array.

Put the context attributes in wxGLCanvasX11 itself instead.

See #16402.

Fix handling of identical consecutive key events

Events generated programmatically may have the same timestamp as the previous
event, which caused them to be ignored on the assumption that they were the same
event being sent to a parent window. Fix this by detecting when a new event could
be generated by the event loop.
Closes #15802

Don't exit event loop when exception occurs inside Yield().

If an unhandled exception occurs in an event handler called from Yield(),
don't exit the current event loop which can continue running after handling
this exception in the code calling Yield().

Closes #16419.

Remove default argument value from wxIHTMLElement2::setExpression().

This doesn't make much sense for an interface declaration anyhow and produces
a warning from g++ about assigning string literal to (non-const) BSTR pointer.

Fix generic wxSearchCtrl size/layout code.

Override DoGetBestClientSize() instead of DoGetBestSize(), as we're really
computing just the size of our contents and like this we don't need to hard
code platform-dependent border sizes in this control itself.

Also use the client size in LayoutControls() for the same reason. This also
makes it unnecessary to pass it the width and height as it can find them on
its own. And x and y were never used in the first place, so remove them too.

Finally, center the bitmaps vertically.

Closes #16422.

Fix ribbon bar tab width computation if the first tab is hidden.

The logic for the first tab should really deal with the first visible tab as
the actual first tab might be hidden and in this case we shouldn't account for
it at all.

Closes #16432.

Merge wxQT branch into the trunk.

This merges in the latest sources from GSoC 2014 wxQt project with just a few
minor corrections, mostly undoing wrong changes to common files in that branch
(results of a previous bad merge?) and getting rid of whitespace-only changes.
Also remove debug logging from wxGrid.

Remove unused variable in wxDCImpl::CalculateEllipticPoints().

Avoid unused variable warning in wxUSE_DATAOBJ==0 build.

Declare variable only used when wxUSE_DATAOBJ==1 inside the check for it.

Closes #16434.

Avoid warning about unused variable in wxiOS build.

Define variable only used if wxOSX_USE_COCOA_OR_CARBON inside the check for it.

Avoid unnecessary assignment in wxOSX build.

Don't assign to the variable only to overwrite it with a new value.

Closes #16436.

Also ignore arch-specific build directories in wxMSW wxStandardPaths.

In addition to ignoring debug/release subdirectories, also ignore their
(possible) parent Win32/x64 directories, and for the same reason: this allows
the code using wxStandardPaths to work even when the program is ran from the
build directory.

Show new style Windows directory selector even for non-existent paths.

Passing an invalid initial directory to wxDirDialog resulted in using the old
style Windows directory selector dialog instead of the new style (file dialog
like) one, which was unintentional, as incorrect initial directory shouldn't
prevent the dialog from being shown.

Fix this by handling ERROR_FILE_NOT_FOUND error specifically and still showing
the new dialog, just without the (non existent) initial directory value, in
this case.

Closes #16430.

Add a test of throwing an exception from wxYield() to except sample.

This demonstrates that under 64 bit Windows exceptions may not propagate
through the kernel code and throwing from inside wxYield() results in either
an immediate abort, even if the code calling wxYield() tries to handle the
exception, or, even more surprisingly, is just completely ignored.

See http://blog.paulbetts.org/index.php/2010/07/20/the-case-of-the-disappearing-onload-exception-user-mode-callback-exceptions-in-x64/
for more information.

Moreover, independently of Windows weirdness, throwing from wxYield() also
results in a difficult to debug crash when using wxGTK because C++ exceptions
can't propagate through C GTK+ code in this case.

No real changes, just simplify SafelyProcessEvent() slightly.

Remove a long comment about initializing "loop" in 2 steps and just do it in 1
step instead.

No changes, just document exception-related methods in their own group.

Extract wxApp::OnExceptionInMainLoop() and OnUnhandledException() in a
separate Doxygen group as there will be more functions defined in it soon.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@77467 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Add wxApp::StoreCurrentException() and RethrowStoredException().

These methods can be used to ensure that the exceptions thrown from event
handlers are safely rethrown from the code dispatching the events once the
control flow gets back there.

This allows to work around the problem with not being able to propagate
exceptions through non-C++ code and can be used, for example, to catch
exceptions thrown by the handlers invoked from inside wxYield() by a try/catch
block around wxYield() -- something that didn't work before, update the except
sample to show that it does work now.

Remove the apparently unnecessary <locale> inclusion.

This header doesn't seem to be needed anywhere.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@77469 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Provide wxApp::StoreCurrentException() implementation for C++11.

When using C++11 we can provide implementations of wxApp::StoreCurrentException()
and RethrowStoredException() ourselves and thus make catching exceptions outside
of the event loop work by default.

Do this and update the documentation and the sample to reflect it.
