piddleGTK

piddle backend for: Gtk+

Applicability

This backend displays the canvas on a Gtk+ GtkDrawingArea widget. The standard interface displays the "info line" as a GtkStatusbar widget packed below the canvas in the same top-level window. Interactivity support is available and works as described in the PIDDLE documentation.

See the docstring in piddleGTK.py for information on alternate classes that can be used in different contexts.

Known Bugs & Limitations

To display the canvas, the Gtk+ mainloop must be running. This can be done by calling gtk.mainloop() after preparing the canvas completely, or by creating the mainloop while the mainloop is already active.
Approaches to work around this have been suggested, but none have been implemented at this time.
PIL support has not been implemented yet.
Rotated text probably won't work for a while, due to constraints on my time. It is planned. Non-rotated text seems to be working fine for the required fonts. Other fonts haven't been checked yet.

Sample Output

The following grabs were made using xv to save PNG images.

(non-rotated text only, for now)

piddleGTK supports non-white backgrounds nicely as well!
(from the test script)

Here are a couple of non-canvas grabs of other parts of the test program; these show the test selection window and test of some of the font-mapping internals.
