I just discovered this object a week ago and have been implementing it to a standalone application I have been making. There are a few functions of the menubar that are not explained in the .maxhelp file or the reference page.
- using the undo/redo function in the edit bar
- adding or getting information from the window bar (ie: wanting to trigger a window closed)
- including a patch that is linked by the help bar.
there is an outlet on the menubar object that pertains to the window bar but when selecting any item in the window bar nothing outputs. so it's obvious that there is a way to access and edit these features but the correct script is unknown.
