Methods
- __init__(self, *args, **kw)
- add_wiring_tool(self)
- draw(self, gc, view_bounds, mode = 'normal')
- get_bounding_box(self)
- load_layout(self, filename)
Loads the layout of the canvas from the given filename.
- remove(self, *components)
Overridden so that a removal causes a redraw automatically. This allows components to remove themselves from the container.
- remove_wiring_tool(self)
- save_layout(self, filename)
Save the layout of the canvas to the given filename.
