Class Details

class GooCanvas.CanvasWidget(**kwargs)

Bases:

GooCanvas.CanvasItemSimple

Abstract:

No

Structure:

GooCanvas.CanvasWidgetClass

GooCanvas.CanvasWidget provides support for placing any Gtk.Widget in the canvas.

The GooCanvas.CanvasWidget :width and GooCanvas.CanvasWidget :height properties specify the widget’s size. If either of them is -1, then the requested size of the widget is used instead, which is the default for both width and height.

Note that there are a number of limitations in the use of GooCanvas.CanvasWidget:

• It doesn’t support any transformation besides GooCanvas.simple translation. This means you can’t scale a canvas with a GooCanvas.CanvasWidget in it.

• It doesn’t support layering, so you can’t place other items beneath or above the GooCanvas.CanvasWidget.

• It doesn’t support rendering of widgets to a given cairo.Context, which means you can’t output the widget to a pdf or postscript file.

• It doesn’t have a model/view variant like the other standard items, so it can only be used in a GooCanvas.simple canvas without a model.

• It can’t be made a static item.
