        :   [`bpy.types.Struct`](bpy.types.Struct.html#bpy.types.Struct "bpy.types.Struct") subclass

    *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**]*) – 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`](bpy.types.Region.html#bpy.types.Region.type "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.
