Overview

Coding that exemplifies how to automatically show or hide the scrollbars on multicolumn listboxes.

 

Description

Some codes require to enable or disable the scrollbar on listboxes when necessary. There is a VI shipping with LabVIEW that can do this for tree-controls, however no such code is available for multicolumn listboxes. The attached code contains a VI that will show or hide the scrollbars on the listbox it is given a reference to. Just place the VI in a rescale event case and run it once for each listbox you have on that front panel. In addition, you also need to run it when the items in the list(s) are changed.

Upgrades can be easily added.

 

 

Requirements

LabVIEW 2015 SP1 (or compatible)

 

Steps to Implement or Execute Code
1. Run the VI
2. Mark/ the check boxes and see how the bar appears/disappears
3. Resize the front panel in order to see how the scrollbars appears
4. Exit the application by clicking the red X in the upper right corner of the front panel
