I ask for help with the question given in the title.
The textBrowser receives links from the process polling the OTRS server for applications with the 'open' flag, if this flag changes to 'close', then the line intended for deletion is transmitted by another signal and must be deleted from the textBrowser.
Wandering around the Internet and documentation did not help to find the answer.
