Are you using the FDK or ExtendScript with Script UI?
I am using the FDK.
Over to Scripting you go then ;>)
Not good news with the FDK dialogs. The description of the ScrollBox reads:
F_ApiScrollBox() displays an array of items and allows the user to choose one.
The arguments for F_ApiScrollBox() also define 'selected_item' as IntT. So unless anyone knows of an undocumented feature, the answer is single selections only.
The reason I asked if you are using ExtendScript is that you can allow multiple selections in its equivalent control.
One way to get around this limitation is to use the double scroll box concept to move items between the two scroll boxes which can be seen in several places in the FrameMaker UI:
I hope that this is useful information?
I'd like to extend the functionality of my existing plugins, so I am not thinking about using ExtendScript now.
But thank you for your advice
Thank you for your advice, I'd like to create two scroll boxes.
