gaphas Gaphas is a GTK+ based diagramming widget Gaphas is a MVC canvas that uses Cairo_ for rendering. One of the nicer things of this widget is that the user (model) is not bothered with bounding box calculations: this is all done through Cairo. Some more features: - Each item has it's own separate coordinate space (easy when items are rotated). - Items on the canvas can be connected to each other. Connections are maintained by a linear constraint solver. - Multiple views on one Canvas. - What is drawn is determined by Painters. Multiple painters can be used and painters can be chained. - User interaction is handled by Tools. Tools can be chained. - Versatile undo/redo system GTK+ and PyGTK_ are required. .. _Cairo: http://cairographics.org/ .. _PyGTK: http://www.pygtk.org/ Arjan J.
