[Mono-winforms-list] Winforms and OSX

Hi

I have not had the time to dive into reading the new code, but from what I
understand about your intentions, you will have to jump to the other side of
the river. X11 will not be available on the Carbon side.

IIUC you don't want to instantiate a true platform instance of a eg
checkbox, but create a 'user-defined' window which will - deep down in the
WM_PAINT message - draw its appearance. On the mac this should be done using
ThemeDrawing APIs, everything else won't be percieved of as 'native'. 

So you won't need a full fledged Quartz2D renderer at the moment, you will
only have to stuff in the cgContext from the Carbon kEventControlDraw event
and pick it up in the WM_PAINT handler and call HIThemeDrawButton
(HITheme.h) The important part will be to setup the Carbon Event handlers at
the appropriate places, repackage and feed into the WM_ message system.

Sorry, if I misunderstood something

Best,

Stefan (wxMac)
