Hi, Carlos Where do you use your drawing operation? As GTK suggested (like GtkDrawingArea), you have to do it in "expose_event":
* The "expose_event" signal to handle redrawing the contents of the widget. Here you can have several if's: if (something) draw_lines(); else draw_other_lines(); "something" can be a simple enum, or gboolean, which is assigned elsewhere. By the way, after changing it, you can send signals by yourself, to redraw your widget.
