How to set set Screen type with python

Question

Found nothing in Python API to set Screen type (other than "Default").

Is it possible?

My need is to set it programmatically, with python script !

Answer 1

bpy.context.screen is a shorthand, but read-only.

You can set a screen via the Window object, which actually holds the screen reference:

bpy.context.window.screen = bpy.data.screens['UV Editing']

http://www.blender.org/documentation/blender_python_api_2_70_release/bpy.types.Window.html#bpy.types.Window.screen

There's also an operator to change screen by a number, relative to the currently active screen:

bpy.ops.screen.screen_set(delta=1) # select screen after current from list

This is what CtrlLeft and CtrlRight trigger (with a delta of -1 or 1 respectively).

Answer 2

You can use bpy.context.window.screen = bpy.data.screens['screen_name']. To see all your screen types, run:

for screen in bpy.data.screens:
    print(screen.name)
