Hi,

I am creating a UI that allows the user to enter and/or scan in a UPC code using a barcode scanner. Currently the setup is such that when the UPC code scans correctly into the desired text field, but the user must enter "tab" to proceed to the subsequent line. Is there a way that I can have the program automatically skip to the following line when a UPC is scanned??? Please Help!!! Thanks.

Often a bar code scanner finishes a scan with a new line character, maybe you could react on that. Some time ago I created a barcode scanner class which interprets the key events of the barcode scanner and turns it into an event. The timing of the input is used to decide whether it is user input or a barcode scanner input. How does your scanner deliver input to your application?

I know zip about barcode scanners, but if you put the scanned result in the textField via setText, simply transfer the focus after setting the text
