I knew this doc, but I didn't understand it as: > Set how to draw lines (the "pen"). If you change this it is your > responsibility to set it back to the default with fl_line_style(0) before you set a colour or another fl_line_style(0). To me it's not telling clearly, that _every_single_ set of linestyle must be reset to default and it is not possible, to change linestyle several times and then reset in general. Might be caused of less text comprehension skills of a non native english reader... ;o) _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
