Edit Labels Model Control GUI

Here is the finished GUI that we started to make during the GUI section of the Advanced Training at the Flexsimposium.

"Objective: Creating a GUI with a listbox that displays all the objects in the model, and a table that displays the selected object's labels for editing.

Attributes discussed: viewfocus, cellwidth, cellheight, items, itemcurrent, OnSelect, OnOpen, OnPreOpen

Commands discussed: c, repaintview(), refreshview(), set(), sets(), nodeinsertinto(), nodeadddata(), nodetopath()

Concepts discussed: “c”, repainting vs. refreshing, VIEW:/active"

For more information about creating GUIs, you can refer to some of Alex's video tutorials: http://www.flexsim.com/community/for...=1428#post1428

I know this is an old post but I think my question would fit in this thread.

How can I make a piece of code execute when I double click on the listbox? I currently have implemented an extra button at the bottom of the listbox that executes code based on the selection that is made in the listbox, but it would be so much nicer if I could simply double click it. As far as I can tell the only trigger that goes off is the OnSelect but that one can't process a double click (at least clicking it twice doesn't give you a pt twice).
The only thing I can think of right now is setting a label the first time it is selected and if it is selected a second time within a certain amount of time it counts for a double click.
Any other solutions?
