  `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 (function) – A function that will be called when the region is drawn. It gets the specified arguments as input. args (tuple) – 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.

  `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.
