wxWidgets/wxPython/wx/lib/art/img2pyartprov.py
Robin Dunn 13db99f1f5 Added some modules from Riaan Booysen:
* wx.lib.flagart:  contains icons of the flags of many countries.

    * wx.lib.art.img2pyartprov: makes images embedded in a python file
      with img2py available via the wx.ArtProvider.

    * wx.lib.langlistctrl: A wx.ListCtrl for selecting a language,
      which uses the country flag icons.

    * An I18N sample for the demo.

""" ArtProvider class that publishes images from modules generated by img2py.
Image modules must be generated with the -u and -n <name> parameters.
Typical usage:
>>> import wx, wx.lib.art.img2pyartprov, myimagemodule
>>> wx.ArtProvider.PushProvider(wx.lib.art.img2pyartprov.Img2PyArtProvider(myimagemodule))
If myimagemodule.catalog['MYIMAGE'] is defined, it can be accessed as:
>>> wx.ArtProvider.GetBitmap('wxART_MYIMAGE')
