Scanning Barcodes

Ignition
1

I know I can scan into an in-focus text field. This works fine. However, I would rather this work without the field being in focus. The operators are not going to like having to click on the field before scanning the barcode.

I am wondering if there is a way around this other than the Sepasoft barcode module. Buying a module is not an option.

Can I catch key strokes at the root container level? I did not see any events for that.

I honestly can not see any way to force the text box in focus without disabling everything on the screen until a barcode is scanned.

Not happy the Perspective has a component included but Vision does not.

p.s; it is against forum etiquette to start multiple topics on the same subject.

Well, that does not answer my question. That only shows me how to focus a textbox when the screen opens.

You tagged this with both Vision and Perspective. Which one do you need a solution for? (Fix your tag.)

no idea how perspective was added as a tag, I did not select it. I am using Vision.

I fixed the post tag for you

For Vision, you have multiple approaches:

  • Use the scanner in keyboard wedge mode, and arrange to have focus in the correct field before scanning.

  • Use the scanner in keyboard wedge mode, but use Sepasoft's Barcode Scanner module to intercept barcodes based on a prefix, sending the result where you like.

  • Use the scanner in keyboard wedge mode, but roll your own application-wide keystroke interceptor via java Swing "under the hood".

  • Use the scanner in USB Serial Port emulation mode, and run a long-lived thread to monitor the serial port. Typically delivering scanned values to a Vision Client tag, from which you can bind or trigger other events.
