colormap free question

[Chris Ellec <cae oco net>]

hello,

I use a colormap with gtk_widget_get_colormap(widget) in an expose_event 
to draw some circles of various colors. This works fine.

However, I imagine I need to do a free(colormap) somewhere. If I put it 
at the end of the expose_event, the program segfaults. Since I have 
colormap as a local variable, I can't free it anywhere else.

Should it be global ? Do I have to free it ?

Thanks for your help,

Chris.
