That's true (although GtkDrawingArea will emit it too). I tried using size-request, and nothing happened (callback never got called). size-allocate, however, caused an infinite loop, because I'm trying to do the following: gboolean solar_cal_pixbuf_resize(GtkWidget *widget, GtkAllocation *alloc, gpointer user_data) { GtkImage *img_widget = user_data; GdkPixbuf *pixbuf = gtk_image_get_pixbuf(img_widget); if (pixbuf) g_object_unref(pixbuf); pixbuf = gdk_pixbuf_new(GDK_COLORSPACE_RGB, TRUE, 8, alloc->width, alloc->height); gtk_image_set_from_pixbuf(img_widget, pixbuf); } The call to gtk_image_set_from_pixbuf causes a size-alloc to be emitted, leading to the infinite loop. I don't see why the size-request signal is not being emitted. Baah, maybe I should just stick to using a GtkDrawingArea instead... -Jim _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
