[wxMac] text event handling (embedded)

[Chad Wagner]

I'm using wxWidgets for my plugin that runs within a variety of host  
apps.  the host passes me a WindowRef, and I have derived my own top  
level window that does not create a new window but rather wraps the  
window I was given into a wxWindow.

I had been using MacInstallTopLevelWindowEventHandler() to attach the  
standard wxWidgets handlers to my window, but there are issues with  
text input (works fine in some hosts, not at all in others, and in  
some depending on whether my window has lost focus since creation,  
etc...)

As a test, I tried it without any of the wx handlers, and defined my  
own just for text:

	static const EventTypeSpec kKeyboardFocusEvents[] =
		{
			{ kEventClassControl, kEventControlSetFocusPart },
			{ kEventClassTextInput, kEventTextInputUnicodeForKeyEvent }
		};
	result = InstallWindowEventHandler(MAC_WXHWND(m_macWindow),  
GetMyHandlerUPP(),
								GetEventTypeCount(kKeyboardFocusEvents),  
kKeyboardFocusEvents, this, &m_myEventHandler );

This works like a charm, I get all text event in all hosts just as I  
would expect.

So that's the setup, now for the question:  Does anyone have an idea  
what it is about the standard wxWidgets event handlers that is  
interfering with my text events, and what I might do to fix it or  
work around it?  I would hate to have to redefine all my own event  
handlers, as the standard ones seem to be working just fine for  
everything other than text.  Besides, I'm no guru, and handling *all*  
events myself is probably more than I can (ahem) handle.

thanks!!
