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.
Returns:

Handler that can be removed later on.

Return type:

object

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.
