I've been thinking about doing something like this myself. I have experimented a little with some success. my trial implementation is both cheesy and limited though, so I won't bother sharing it. my future plan is to create a new object to implement this. the way it works: - instanciate a new object of this kind - add any number of widget objects, one at a time, to the "blink it" list - set the blink type (there can be a variety) - set the on-off blink duration - set the blink colors - set the number of blinks that occur when an alert happens once you have a set of widgets in the object you can initiate the alert by calling some function in the "GtkBlinkIt" object. The blinking can be made to stop prematurely through signals. I think the actual blinking should be implemented by changing the color of the widgets. The only reason I haven't already done this is I haven't had enough time and the GtkMessageDialog serves more or less the same purpose. - Ben _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
