Notes
-
OnPanelSwitch applies to the entire panel control and not to individual panels. To control switching to particular panels, use the Get(TriggerCurrentPanel) and Get(TriggerTargetPanel) functions.
-
Because this script trigger is activated before the panel switch event is processed, the value of the script parameter that OnPanelSwitch passes to your script is determined before the panel is switched. Therefore, if you use the script parameter to pass the returned value of Get(TriggerCurrentPanel) or Get(TriggerTargetPanel) into your script, the value will be zero. To get useful returned values, use these functions only within the script activated by OnPanelSwitch, not in the script parameter.
