Wie Strg + Shift + Numpad Tasten zur Unterstützung mit java.awt

Question

I ctrl + Verschiebung + Numpad 7 auf eine Aktion Karte zuordnen möchten. Im Grunde versuche ich, meine Aktionen an Tastaturkürzel zu binden und möchte das gleiche Verhalten wie die von oben gedrückten Zifferntasten oder die von den richtigen Tastaturnummern gedrückten Zifferntasten.

Ich bin in der Lage

im.put(KeyStroke.getKeyStroke(KeyEvent.VK_A, KeyEvent.CTRL_DOWN_MASK | KeyEvent.SHIFT_DOWN_MASK), "Ctrl+4"); 

zur Karte aber

im.put(KeyStroke.getKeyStroke(KeyEvent.VK_NUMPAD2, KeyEvent.CTRL_DOWN_MASK | KeyEvent.SHIFT_DOWN_MASK), "Ctrl+4"); 

hier nicht abbilden kann, ist der Code, den ich auszuführen versuche:

package testmaik; 

import java.awt.Dimension; 
import java.awt.EventQueue; 
import java.awt.GridBagLayout; 
import java.awt.event.ActionEvent; 
import java.awt.event.KeyEvent; 
import javax.swing.AbstractAction; 
import javax.swing.ActionMap; 
import javax.swing.InputMap; 
import javax.swing.JFrame; 
import javax.swing.JLabel; 
import javax.swing.JPanel; 
import javax.swing.KeyStroke; 
import javax.swing.UIManager; 
import javax.swing.UnsupportedLookAndFeelException; 

public class KeyBindingsTest { 

public static void main(String[] args) { 
    new KeyBindingsTest(); 
} 

public KeyBindingsTest() { 
    EventQueue.invokeLater(new Runnable() { 
     @Override 
     public void run() { 
      try { 
       UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); 
      } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) { 
       ex.printStackTrace(); 
      } 

      JFrame frame = new JFrame("Testing"); 
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
      frame.add(new TestPane()); 
      frame.pack(); 
      frame.setLocationRelativeTo(null); 
      frame.setVisible(true); 
     } 
    }); 
} 

public class TestPane extends JPanel { 

    private JLabel state; 

    /** 
    * 
    */ 
    public TestPane() { 
     setLayout(new GridBagLayout()); 
     state = new JLabel("Nothing here"); 
     add(state); 

     InputMap im = getInputMap(WHEN_IN_FOCUSED_WINDOW); 
     im.put(KeyStroke.getKeyStroke(KeyEvent.VK_1, KeyEvent.CTRL_DOWN_MASK), "Ctrl+1"); 
     im.put(KeyStroke.getKeyStroke(KeyEvent.VK_2, KeyEvent.CTRL_DOWN_MASK), "Ctrl+2"); 
     im.put(KeyStroke.getKeyStroke(KeyEvent.VK_NUMPAD1, KeyEvent.CTRL_DOWN_MASK), "Ctrl+1"); 
     im.put(KeyStroke.getKeyStroke(KeyEvent.VK_NUMPAD2, KeyEvent.CTRL_DOWN_MASK), "Ctrl+2"); 
     im.put(KeyStroke.getKeyStroke("ctrl 7"), "ctrl+7"); 
     im.put(KeyStroke.getKeyStroke("ctrl shift 7"), "Ctrl+3"); 
     im.put(KeyStroke.getKeyStroke(KeyEvent.VK_NUMPAD2, KeyEvent.CTRL_DOWN_MASK | KeyEvent.SHIFT_DOWN_MASK), "Ctrl+4"); 

     ActionMap am = getActionMap(); 
     am.put("Ctrl+1", new MessageAction("Ctrl+1")); 
     am.put("Ctrl+2", new MessageAction("Ctrl+2")); 
     am.put("Ctrl+3", new MessageAction("Ctrl+3")); 
     am.put("ctrl+7", new MessageAction("ctrl+7")); 
     am.put("Ctrl+4", new MessageAction("Ctrl+4")); 
    } 

    @Override 
    public Dimension getPreferredSize() { 
     return new Dimension(200, 200); 
    } 

    public class MessageAction extends AbstractAction { 

     private String message; 

     public MessageAction(String message) { 
      this.message = message; 
     } 

     @Override 
     public void actionPerformed(ActionEvent e) { 
      state.setText(message); 
     } 

    } 

} 

} 

Bitte helfen.

Eine alternative Lösung: Versuchen Sie, diese im Ihre TestPane Klasse und Sie können das Ereignis fangen sich:

getRootPane().getContentPane().getToolkit().addAWTEventListener(new AWTEventListener() { 

     public void eventDispatched(final AWTEvent event) { 
      if (event.getID() == KeyEvent.KEY_PRESSED) { 
       final KeyEvent keyEvent = (KeyEvent) event; 
       switch (keyEvent.getKeyCode()) { 
        case KeyEvent.VK_NUMPAD7: 
         if(keyEvent.isControlDown() && keyEvent.isShiftDown()) { 
          //do Stuff 
         } 
         break; 
       } 
      } 
     } 

    }, AWTEvent.KEY_EVENT_MASK); 

Ich bin nicht sicher, was mit Ihrer Event Karte falsch ist.
