GooCanvas.cairo_matrix_copy(matrix)

Parameters:

matrix (cairo.Matrix) –

Return type:

cairo.Matrix

GooCanvas.cairo_matrix_free(matrix)

Parameters:

matrix (cairo.Matrix) –

GooCanvas.canvas_item_class_find_child_property(iclass, property_name)

Parameters:

• iclass (GObject.ObjectClass) – a GObject.ObjectClass

• property_name (str) – the name of the child property to find

Returns:

the GObject.ParamSpec of the child property or None if class has no child property with that name.

Return type:

GObject.ParamSpec

This function is only intended to be used when implementing new canvas items, specifically layout container items such as GooCanvas.CanvasTable.

It finds a child property of a canvas item class by name.

GooCanvas.canvas_item_class_install_child_property(iclass, property_id, pspec)

Parameters:

• iclass (GObject.ObjectClass) – a GObject.ObjectClass

• property_id (int) – the id for the property

• pspec (GObject.ParamSpec) – the GObject.ParamSpec for the property

This function is only intended to be used when implementing new canvas items, specifically layout container items such as GooCanvas.CanvasTable.

It installs a child property on a canvas item class.

GooCanvas.canvas_item_class_list_child_properties(iclass)

Parameters:

iclass (GObject.ObjectClass) – a GObject.ObjectClass

Returns:

a newly allocated array of GObject.ParamSpec. The array must be freed with GLib.free().

Return type:

[GObject.ParamSpec]

This function is only intended to be used when implementing new canvas items, specifically layout container items such as GooCanvas.CanvasTable.

It returns all child properties of a canvas item class.
