Zeige ein Jdialog-Feld an, wenn ein Jbutton einen Mausklick erhält

Ich stecke auf einem Problem, wo ich auf einen Menüpunkt klicke und es brauche, um eine JDialog Box zu öffnen, aber es wird nicht angezeigt. Die Codierung ich habe recherchiert und herausgefunden, dass ich verwenden soll, wenn im nicht irre ist so etwas wieZeige ein Jdialog-Feld an, wenn ein Jbutton einen Mausklick erhält

if(evt.getSource == Jmenuitem1) 
Jdialog.setVisible(true); 
Jdialog.setBounds (400,0,400,400)

Im Folgenden wird die vollständige Codierung für die Klasse im arbeiten. Warum tut es nichts, wenn ich auf den Menüpunkt klicke.

Können Sie anstelle dieses vollständigen Code einen Testfall zur Verfügung stellen? –

Wie mache ich das, sorry, ich habe das nie zuvor getan – user519670

Nevermind, ich fand heraus, wie, editierte ich den ursprünglichen Beitrag, Testergebnisse sind am unteren – user519670

Sie sollten Action anstelle von Mouselistener Ereignisse zu verarbeiten. Wechsel:

newdvd.addMouseListener(new java.awt.event.MouseAdapter() { 
    public void mouseClicked(java.awt.event.MouseEvent evt) { 
     newdvdMouseClicked(evt); 
     newdvdMouseClicked1(evt); 
    } 
});

zu:

newdvd.addActionListener(new ActionListener() { 
    public void actionPerformed(ActionEvent e) { 
     input1.setVisible(true); 
     input1.setBounds(400,0,400,400); 
    } 
});

Und Ihre Dialog wird sich zeigen.

Ok, so sagen Sie mir, warum dies mit einem actionperformed gegen eine Maus arbeitete angeklickt ......... – user519670

Das ist die Art und Weise, wie man Ereignisse aus dem 'MenuItem' behandelt. Wie es funktioniert, ist hier beschrieben: http://download.oracle.com/javase/tutorial/uiswing/components/menu.html#event Ich habe mich selbst nie überprüft, aber ich nehme an, dass MouseEvent durch das Popup und das verbraucht wird ist der Grund, warum Menüpunkte dieses Ereignis nicht erhalten. –

Statt mouseClicked Ereignis Verwendung mit:

public void mousePressed(java.awt.event.MouseEvent evt)
