Re: [matplotlib-devel] mathtext in wx widgets
It would probably be considerable work to ply mathtext out of matplotlib, particularly if you consider bringing along the Ps/Pdf/Svg/Cairo backends. Just bringing the raster backend (which is really in ft2font.cpp) would be considerably less work. But I was mainly just sharing a "wouldn't it be cool if...". Separating mathtext would be a project unto itself. Cheers, Mike - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

Re: [matplotlib-devel] mathtext in wx widgets
There is now preliminary support for getting a mathtext bitmap to transfer to a GUI widget in SVN, along with a toy wxPython example in examples/mathtext_wx.py. I've only tested this on Linux/wxGTK2/wxPython-2.8. I'd appreciate help with testing (and screenshots) on any other platforms you may care about. Gtk+ and Qt should also be theoretically possible. Tk will be more difficult, because a) it doesn't support an alpha channel (which would mainly be a quality problem), and b) you have to use the _tkagg C++ bridge to get the image data into a widget. Be aware that the API for this may change due to my planned mathtext/backend communication refactoring. If you do plan on relying on this functionality, I recommend wrapping it in a function (like mathtext_to_wxbitmap in the example) so any future changes will be localized.

Re: [matplotlib-devel] mathtext in wx widgets
I should also mention my mathtext_wx.py example reveals a [possible] bug in wxPython-2.8 and/or the underlying Gtk. When you put a bitmap on a menu item, the *height* of the menu item is determined by the *width* of the bitmap. And placing bitmaps in menu items reportedly doesn't work at all on wxCocoa. -- so maybe it's best to stay away from that altogether.

I'm attaching a screen shot for wx 2.8 on OS/X. The rendering is kind of ugly, but I haven't looked into it. - Paul <>- This SF.net email is sponsored by: Splunk Inc.

The wxPython demo.py for menus has a smiley face bit map that displays just fine. Let me know if you want a screen shot. - Paul - This SF.net email is sponsored by: Splunk Inc.
