closing widget window

[yen(at)dolphin.upenn.edu (Harry Kao)]

I am running IDL 5.4 under Mac os9.1

Is is possible to put a little square icon on the upper left corner of a 
widget window, like the one on a usual system window, to allow user to 
click on it and close the window?

Right now, I have to generate a 'quit' icon on every widget window, use
use the event handler and then "widget_control, event.id, /destroy"
to close the window. This gets troublesome when I have to open several 
windows at the same time, and this also takes up too much window space.

Thank you.

Harry
