[Gimp-developer] Problem refreshing GimpPreviewArea

Hi! I am using GimpPreviewArea to show previews in my plugin dialog.
My problem is that when the size of area changes and i draw it. It
doesn't refresh the contents but if I minimize the dialog and then
show it again the area is refreshed.

I've tried to use gtk_widget_queue_draw_area but it doesn't work. Any
idea?
