The TellEvent Method requests and returns a single event from the device without removing it from the input queue. Single events are defined as either a key stroke, a function key sequence, or a scanned barcode.
Syntax
public String TellEvent()
throws WaveLinkError
Returns
The returned input event
Throws
WaveLinkError
Remarks
TellEvent does not remove any returned input values from the input queue. This method simply checks for user input without pausing your application.
To actually remove returned input from the input queue, a subsequent call to another input method, such as GetEvent Method to return the origin of the last input type (i.e., scan, keypad, or function key input).
If the local input queue is empty, TellEvent also checks the output queue on the mobile device before returning.
