Press/Release Script

What it is and what it is for

Press/Release Script has a fixed Pointer Button trigger. The runtime accepts a real primary left-pointer interaction: pointerdown runs Pointer Press, while pointerup, pointercancel, or lost pointer capture enters Pointer Release. Unlike Click Script, it distinguishes the held and released phases.

How to use it: design the scripts as a pair

The editor provides two full script boxes, Pointer Press and Pointer Release, with no separate Condition field. The press script enters a temporary state; the release script exits or resets it. Both scripts can use object, objects, event, tag, page, presentation, shape, hqVisuDesigner, and globals.

• Pointer Press: runs on the primary pointer press, for example write a momentary command true, show a pressed state, or begin a temporary action.
• Pointer Release: runs on release, cancellation, or lost capture, for example write false, restore styling, or end the action.
• Each script is syntax-validated separately. An empty phase script does not run.
• Tag writes still depend on host permission, confirmation, reason, and audit processing; a script call is not proof that the device completed the action.

// Pointer Press
WriteTagBoolean("<CommandTag>", true);

// Pointer Release
WriteTagBoolean("<CommandTag>", false);

When to use it

Use it for actions that remain active until the operator releases the pointer: motor jog, manual valve movement, a temporary acknowledgement, a hold-to-preview state, or pressed-state feedback. Keep one-shot submissions, navigation, and fixed writes in Click Script, Open Link, or Write Tag.
