This member of Class WaveLinkIO is supported on iOS, Windows Mobile, Windows CE, Palm, and DOS.
The GetEvent Method requests and returns a single event from the device. Single events are defined as either a key stroke, a function key sequence, or a scanned barcode.
Syntax
public String GetEvent()
throws WaveLinkError
Returns
The single key, function key, or scan input value
Throws
WaveLinkError
Remarks
Unlike a standard input, which only returns after a carriage return or the maximum input length has been reached, GetEvent immediately returns a single character, function-key combination, or a scanner event.
GetEvent only returns the first key stroke or function key sequence but returns the entire value for a scan input.
Use the LastInputType Method to return the origin of the last input type (i.e., scanner, keypad, or function key).
Example
WaveLinkIO IOIface = new WaveLinkIO();
WaveLinkTerminal termIface = new WaveLinkTerminal();
String pszVerifyIn;
.
.
.
try {
// Do something to instruct the user to enter input.
IOIface.RFPrint(0, (termIface.TerminalHeight() – 1), "Verify y/n ? ", WaveLinkIO.WLREVERSE | WaveLinkIO.WLCLREOLN);
pszVerifyIn = IOIface.Getvent();
}
catch (WaveLinkError wlErr) {
}
