Hi all,

I am trying to create an editor using JTextpane. Now I need to show a dynamic pop up menu while pressing Ctrl + space. But the problem is that I can trigger the pop up menu only by right click of mouse. The code snippet that I used is given below.

frame.addMouseListener(new MouseAdapter(){
                    public void mouseReleased(MouseEvent Me){
                      if(Me.isPopupTrigger()){
                        Pmenu.show(Me.getComponent(), Me.getX(), Me.getY());
                      }
                    }
                  });

I am able to invoke Ctrl + space.. But not able to invoke pop up menu using this.Is there any method or short cut to trigger pop up menu using key board? Please help...
Thanks in advance......

Listen for the key press and take action thereafter. I think this should work:

Java

frame.addKeyListener(new java.awt.event.KeyAdapter() {
    public void keyPressed(java.awt.event.KeyEvent evt) {
        if (evt.isControlDown() &&
                evt.getKeyCode() == java.awt.event.KeyEvent.VK_SPACE) {
            Pmenu.show(this, this.getX(), this.getY());
        }
    }
});
