[Glade-users] what widget does this?

[jdhunter ace bsd uchicago edu (John Hunter)]

I need to present a long list of strings and have the user select a
subset of them, much like the dialog that pops up in glade when you
click on the Events listing under the Common tab in the Properties
view.  

I would like the user to be able to toggle the selection of one line
by clicking on it, select multiple lines by holding down the control
key, select a range with the shift key, and so on.  Is there a good
widget for this to speed me on my way?

Thanks,
John Hunter
