Event Data Fields

NameDescription
SourceSource of the event. LabVIEW UI refers to any built-in user interface event.

0LabVIEW UI
TypeType of event that occurred, such as Mouse Down, Value Change, Timeout, and so on.
TimeValue of the millisecond timer when the event occurred.
TimeValue of the millisecond timer when the event occurred.
CtrlRefReference to the control on which the event occurred.
ButtonValue that corresponds to which mouse button the user clicked. Left mouse button is 1, right mouse button is 2. Operating systems might assign higher numbers if you have a mouse with more than two buttons. For filter events, you can modify the data returned by this event data field.
ModsCluster 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.
PlatModsCluster 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.
Discard?Allows you to prevent LabVIEW from processing the event, bypassing the behavior normally triggered by that event. The default is FALSE.
