Using barcode scanner causes disappearing of GUI of application
-
Hi there,
my application, which I developed with Qt5.12.7, runs on raspbian buster headless.
In the application I use a hand scanner to read barcodes. In the application, the characters read by the barcode scanner are treated like keyboard input.
Everything works fine.
But when the barcode scanner is used, the GUI of the application sometimes disappears for a short time and then becomes visible again.
What is this and what can I do to prevent it?
I can also see in the command line that the barcodes read are not only displayed in my application but also in the command line.
Can I stop that somehow?Kind regards,

Not knowing anything about the implementation, it's hard to tell anything about what is going on.
