Editbox with Filelistbox 

 Keywords: Editbox Filelistbox scroll

Question:

I have a 6.1 dialog with an editbox linked with a filelistbox as the same variable, I'd like the filelistbox to scroll the files when I input the first letter in the editbox, is this possible?

how can i do that?

Answer:

Sounds possible. Basically you need a Dialog Callback where you capture the editbox contents on each character input and examine it. You use this to scan a variable containing the dialogbox contents, then set the scroll position of the listbox with DialogControlSet 10.
