reviewed by: John Harper * configure.in: * libnautilus-extensions/nautilus-background-canvas-group.c: (nautilus_background_canvas_group_initialize_common), (nautilus_background_canvas_group_initialize), (nautilus_background_canvas_group_supplant_root_class): * libnautilus-extensions/nautilus-background-canvas-group.h: * libnautilus-extensions/nautilus-background.c: (nautilus_background_set_up_canvas): Turned on dithering for canvases (aa mode). We no longer expose NautilusBackgroundCanvasGroupClass, in nautilus-background-canvas- group.h. Now we just provide an API to do the class change.

/* nautilus_background_canvas_group_supplant_root_class is used internally by
|
|
NautilusBackground to change the class of a canvas in order to customize its
|
|
background drawing. The reason we have to change the class of a canvas group is
|
|
that the cleanest way to hook into the code that erases the canvas is to be the
|
|
root canvas group. But the canvas class creates the root object and doesn't allow
|
|
it to be destroyed, so we change the class of the root object in place.
|
|
|
|
A future version of GnomeCanvas may allow a nicer way of hooking in to the code
|
|
obviating this fn.
|
|
|
|
This fn is private to NautilusBackground.
