Requires: Base Development System
Class: VI Events
Generated when the user releases a key on the keyboard.
|Note LabVIEW only generates events for the Cluster»All Elements source when the cluster has keyboard focus, not when an individual element inside the cluster has keyboard focus.|
|Source||Source of the event. LabVIEW UI refers to any built-in user interface event.
|Time||Value of the millisecond timer when the event occurred.|
|VIRef||Reference to the VI on which this event occurred.|
|ScanCode||Scan code unique for each key on the keyboard. The values are unique for each physical key, and allow you to match Key Up and Key Down events.|
|Mods||Cluster of Booleans that contain platform-independent modifiers. LabVIEW returns all platform-dependent modifiers in the PlatMods event data field. For key events, this event returns a Boolean indicating if the event occurred on the numeric keypad. For mouse events, this event returns a Boolean indicating if the event was a double-click. For both events, a Boolean is returned if the platform-independent menu key, such as <Ctrl> on Windows or <Command> on Mac OS X, was pressed when the event occurred. For filter events, you can modify the data returned by this event data field.|
|PlatMods||Cluster of Booleans that contain platform-dependent modifiers. Specifies if platform-dependent keys, such as <Ctrl>, <Shift>, <Alt>, <Command>, and <Option> were held down when the event was triggered. For filter events, you can modify the data returned by this event data field. A key can be both a Mod and PlatMod. For example, <Ctrl> is the platform-independent menu key on Windows, but you also can use it in platform-dependent programming.|
|FocusObj||A reference to the object that has keyboard focus. When the event is for a control, it might be a sub-component, like a scale, label, and so on, rather than the control itself. You also can modify the data returned by this event data field.|
