widget_class->draw (a bug?)

[Adrian Feiguin <adrian ifir ifir edu ar>]

I'm working on a widget and I defined the function widget_class->draw.
 In previos versions of gtk (e.g. 0.99.3) my widget ran without
problems, but in gtk+-1.0.* the widget is redrawn calling this function
aparentrly at random, without any logic. I can't understand this behavior
and I dont know whether is a bug in gtk or I'm missing something.

Thank you,
