I began using the multichoice option since I only need to select one item at a time. But I have over 100 items and the popup menu runs off the bottom of the screen and many choices are not visible. And menus with more than a couple of dozen items are a bit clunky anyway.
The list option only allows multiple items to be selected, but I need only one. Also, the help strings do not pop up in the list box, as they do for the multichoice option.
A drop down list box might be the best choice here, but I don't see that one is available to be called from scheme.
Questions:
1. Is there a list option with single choice only?
2. Is there a list option that displays the help strings?
3. Could the multichoice option be fixed to keep all of the choices on the screen?
4. Is there or could there be a drop down list box option?
5. Is there a way to implement callback functions in scheme for events such as button clicks, list box selection changes, etc.?
I haven't looked at any of the c code, as I was hoping to do all of this in scheme, but that may not be possible.
