redraw widget

[Yann Leboulanger <asterix lagaule org>]

Hi all,

I have a question about glib idle list. I'd like to redraw a widget, 
without doing what is in idle list. e.g:
g_idle_add(func)
gtk_progress_bar_set_fraction(pb, 0.33)
<- Here I'd like to draw the progressbar without executing func.
g_idle_add(func2)
gtk_progress_bar_set_fraction(pb, 0.67)
<- Here I'd like to draw the progressbar without executing func nor func2.

Is that possible?

Thanks for your help
