Hey Jeff, There are examples in the ENVI Help on how to use auto_wid_mng, which is only used for event handling of ENVI classic compound widgets. Nearly all of the ENVI 'WIDGET' routines show how to call auto_wid_mng. Are you looking for something more specific?

Hey Mari, Just to be clear...i'm not asking how to write my own GUI using auto-managed widgets (ie, how to call auto_wid_mng, etc.) I'm asking about how to write my own *widget* (like widget_multi, or widget_outf) that auto_wid_mng can do something with. I keep finding myself in situations where I need a simple GUI, and I could easily use the auto-managed widgets 80% of the time - except there often seems to be one little situation where auto-managed widgets don't quite get me the functionality i need, and i end up writing my own event handler. So I'm thinking of setting up a couple of compound widgets, and of course my next thought was "wouldn't it be nice if auto_wid_mng() could handle this thing?" :)

You would have to use widget_auto_base to create the top level base along with auto_wid_mng then you can have your own auto managed custom widgets. Note the auto managed widget will be modal.
