Re: [Visualpython-users] More wxPython progress

[Guilherme B. T. <gui...@gm...>]

Dear Bruce,

Congratulations for the progress with wxPython.

I'm trying to get it to run on OS X 10.6.8.
For that I'm hacking around with the build system. In short, I removed 
X11, GTK and added mac_font_rendering to the build. The compilation runs 
till it chokes on the font_renderer.

With wxPython, if understand correctly, besides solving the main thread 
issue one can also remove the X11 and GTK dependencies.

Isn't it so that by dropping GTK (and the rendering via pango) we need 
to switch back to the mac_font_rendering?

The header for and the function ATSUFindFontFromName is nowhere to be 
found on my system. Isn't it only for the deprecated Carbon?

I guess the font_renderer need a bump from ATSUI to CoreText in order to 
work with the Cocoa text system.

Is the above the right way to go?

So far I found some snippets that might help with the transition to 
CoreText [1]

Regards,
Guilherme Torri
