ich bin dabei eine Adressverwaltung zu erstellen.
Meine Adressdaten verwalte ich in einer json-Datei.
Zur Ausgabe und Verwaltung, verwende ich QTableView.
Bei EMail-Adressen verwende ich Hyperlinks.
Ich poste hier mal meinen Code, der lauffähig ist.

sys.exit(app.exec_())Es gibt 2 Punkte, die ich vorrangig behandeln möchte.
Punkt 1:
Callback Funktion die es ermöglicht, bei Änderung der EMail-Adresse, den Hyperlink zu aktualisieren.
Punkt 2:
Beim klicken auf den Hyperlink der EMail-Adresse, öffnet sich dann das Standard EMail-Programm bei mir. Jedoch wird nicht die ausgewählte Ziel-Adresse in meinem EMail-Programm Thunderbird angezeigt.
Wünsche Euch einen schönen 1.Mai !
