* Beschreibung:
|
||||||
|
* Grundgerüst der grafischen Benutzeroberfläche des rs2322tcp-Clients.
|
||||||
|
*
|
||||||
|
* Die GUI verwendet Fyne und stellt die Benutzeroberfläche für den
|
||||||
|
* technischen rs2322tcp-Client bereit.
|
||||||
|
*
|
||||||
|
* Die eigentliche Kommunikation mit dem Server sowie die Verwaltung der
|
||||||
|
* virtuellen seriellen Ports bleiben vollständig in internal/client.
|
||||||
|
*
|
||||||
|
* Der technische Client wird im Hintergrund gestartet, damit das Fyne-
|
||||||
|
* Fenster unmittelbar angezeigt werden kann. Dadurch bleibt die GUI auch
|
||||||
|
* dann bedienbar, wenn der Server nicht erreichbar ist oder der Aufbau
|
||||||
|
* der Verbindung längere Zeit benötigt.
|
||||||
|
*
|
||||||
|
* Aktualisierungen von Fyne-Widgets aus einer Hintergrund-Goroutine werden
|
||||||
|
* über fyne.Do() auf den Fyne-GUI-Thread übertragen.
|
||||||
|
*
|
||||||
|
* Die GUI stellt außerdem die Funktion "Server neu verbinden" bereit.
|
||||||
|
* Dabei wird die bestehende technische Client-Anwendung beendet und
|
||||||
|
* anschließend vollständig neu gestartet. Dadurch wird die aktuelle
|
||||||
|
* client.json erneut geladen.
