You are better off taking the Roll Clip button from the ViewControl screen instead of the virtual panel as it is a simple toggle button. The buttons on the virtual panels are a little more difficult to interact with.
If you drag this Roll Clip button to a custom panel, you can attach a task to it to run whenever the button changes state - just drag it onto a custom panel, go into edit mode in your panel, and attach a task to do whatever action you want.
Cheers.
