when is Key down event case triggered

[lordsathish]

Hi all,

In event structure there is an event <this VI> key Down? 

When will this event be triggered... i.e will this event be triggered only in case of a keyboard entry... ?

Or in case i use a barcode reader, if data gets populated in a control on the Front panel through the barcode reader will this trigger this event...?

Thanks

The Key Down event will only be fired when a key is pressed on the keyboard.  If you want to fire an event off of a Front panel control, you can either use a User Event or a property node called Value (Signaling).  This property node will cause a Value Change event to trigger when the value of the Front panel control changes.

Cheers
