I am using the dockableWorkspaceWidget.py from maya’s devkit as a base for dockable window I am creating. I am having an issue though that if I leave the window open and close maya, then re launch maya, the window is still open (I would rather not have it automatically open), and the window is completely blank (widgets are all missing). Trying to relaunch the window will just cause errors.
Does anyone know how to make sure this UI is deleted upon closing maya, and so it does not re open when maya is re launched.
