JInternalFrame non decorato diventa decorato se visualizzato tramite Condivisione desktop remoto

Question

Ho riscontrato un problema con l'implementazione JInternalFrame. Ho reso il JInternalFrame non decorato, in modo che la barra del titolo e il bordo dello JInternalFrame vengano rimossi. Il problema si verifica nel seguente scenario.

1. Eseguire il programma in un computer Windows 7.

   • A questo punto lo JInternalFrame rimane non decorato.

2. Accedi alla macchina Windows 7 utilizzando la condivisione desktop remoto da un'altra macchina.

   • Ora la barra del titolo e il bordo della cornice interna diventano visibili.

Questo problema si verifica solo in Windows 7 la macchina, e non in Windows XP. È possibile accedere al computer Windows 7 utilizzando la condivisione del desktop remoto da un altro computer Windows 7 o Windows XP.

Anche se si accede alla macchina utilizzando la condivisione del desktop remoto prima, e quindi si esegue il programma, JInternalFrame rimane non decorato.

Passaggi per riprodurre

Fase 1: eseguire l'applicazione in una macchina di Windows 7.

Passaggio 2: accedere all'apparecchio di Windows 7 utilizzando la condivisione del desktop remoto da un'altra macchina Windows 7 o Windows XP.

Fase 3: Controllare la GUI dell'applicazione

Risultato: - La barra del titolo e il bordo del undecorated JInternalFrame diventa visibile.

Se qualcuno ha affrontato questo problema o se qualcuno ha una soluzione per questo problema, condividi gentilmente i tuoi pensieri.

Answer 1

è necessario mettere proprietà non decorato come non condiviso .setUndecorated (vero) per le istanze InternalFrame.

o provare

JInternalFrame frame = new JInternalFrame("frame", false, false, false, false); 
frame.putClientProperty("JInternalFrame.isPalette", Boolean.TRUE); 
frame.getRootPane().setWindowDecorationStyle(JRootPane.NONE);
