classmethod draw_handler_add(callback, args, region_type, draw_type)#

Add a new draw handler to this space type. It will be called every time the specified region in the space type will be drawn. Note: All arguments are positional only for now.

Parameters:

  • callback (Callable[[Any, ...], Any]) – A function that will be called when the region is drawn. It gets the specified arguments as input, it’s return value is ignored.

  • args (tuple[Any, ...]) – Arguments that will be passed to the callback.

  • region_type (str) – The region type the callback draws in; usually WINDOW. (bpy.types.Region.type)

  • draw_type (str) – Usually POST_PIXEL for 2D drawing and POST_VIEW for 3D drawing. In some cases PRE_VIEW can be used. BACKDROP can be used for backdrops in the node editor.

Returns:

Handler that can be removed later on.

Return type:

object

classmethod draw_handler_remove(handler, region_type)#

Remove a draw handler that was added previously.

Parameters:

  • handler (object) – The draw handler that should be removed.

  • region_type (str) – Region type the callback was added to.
