Event für SetGadgetText funktioniert nicht.

[funkheld]

Hallo, ich habe ein Programm umgebaut um es mit einem Button zu starten.
Das Programm startet und die texte_e werden erst nach Beendigung reingeschrieben im Editfenster. Eigentlich sollte der Text "starte..." erscheinen, dann soll die Aufnahme erfolgen usw.

Wie kann man das so proggen?

[STARGÅTE]

Nachdem du SetGadgetText(#Editor_0, text_e)
schreibst, wird sofort SaveWave(10 , "Test.wav") gestartet.

Es fehlt also ein WindowEvent, um die Ereignisse (und Änderungen) zu verwalten.
Desweiteren wird das ganze Fenster einfrieren, wenn SaveWave() lange braucht.

Also entweder einen Thread benutzen, damit das Speichern parallel abläuft, oder ein WindowEvent() einbinden...

Bei solchen Dingen kommst du eigentlich nicht um einen Thread herum.
So in etwa würde ich das machen:

Jup, danke.

Funktioniert gut mit deiner Lösung.
