You have to write code that is executed when the user clicks the disclosure triangle and exposes the contents of the folder. My goal is to have two flow sensors which display the amount of water that flows though each sensor on the screen. (Raspberry Pi) I have a raspberry pi 3 running a program made in Xojo. The sublist is just another instance of a CTreeListedValues list, which will be shown hierarchically in the ListboxOnce youve built your (hierarchical) list, you just assign it to the subclassed Listbox. Xojo detect input from 2 inputs with interrupts. In a hierarchical Listbox, some of the lines are hidden (collapsed), so the Listbox can't store that information.

This is an important and complicated subject that I decided would make an excellent topic for Beginner's Corner. Recently a subscriber wrote me with a question about working with hierarchical listboxes. Pane in the lower right portion of the window gives a hierarchical view oft he. He's had fun learning ever since.Īrticle Description: No description available.
