    def window_lod (self):
        if cmds.window('ExampleWindow', exists=True):
            cmds.deleteUI('ExampleWindow', window=True)
        cmds.window( 'ExampleWindow' )
        cmds.columnLayout()
        cmds.text( label='Size and position the window before closing it.' )
        cmds.button( label='Close', command='testing' )
        cmds.showWindow( 'ExampleWindow' )

	def window_lod (self):
		if cmds.window('ExampleWindow', exists=True):
