""" 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')
|
||
|
|
|
||
|
