Re: inserting ColorButton in CellRenderer ....

["Roberto Alejandro Espí Muñoz" <teratux gmail com>]

Ok I saw it .. What I don't understand is why do you have to paint the widget from scratch?? and check if it is active, or toggled to paint that particular behaviour?? isn't there a simpler way to just add it to the cell and call the widget's own paint function?? The widget I want is a little more complex it has an inner rectangle showing the current color. 

Thanks

The best way to understand those functions behavior is to look at source
code:

gtkcellrenderertext.c
gtkcellrenderertoggle.c

get_size_vfunc - should set width and height for cell you are going to
poaint button on.

render_vfunc - should paint the button itself.

I will attach source of my ButtonRenderer (Button with text) to give you
some hints. But don't copy it to your code, just get some clue how to
implement your renderer.
