Ich weiß, ich habe nicht viel code geschrieben, ab jetzt bin ich nur versuchen, herauszufinden, wie, um die Anwendung auszuführen. Ich bin neu auf all dies, so dass jede Hilfe würde geschätzt, danke!
- Wenn Sie fortsetzen stecken zu bleiben, möchten Sie vielleicht, um auf diese einfache JavaFX-Rechner Quelle.
Du musst angemeldet sein, um einen Kommentar abzugeben.
Haben Sie die falsche Einfuhren im controller.
java.awt.Button
undjava.awt.Label
solltejavafx.scene.control.Button
undjavafx.scene.control.Label
ersetzen Sie diese fxml-Pfad-
mit dabei-
