How to use KeyEvent

Question

I'm writing small graphics editor and I want catch event when I press Ctrl+A

I use such code (this is test version):

@Override
public void keyPressed(KeyEvent e) {
    System.out.println("Press");
    switch (e.getKeyCode()){
        case KeyEvent.VK_A :
            System.out.println("A");
            break;
    }
}

but I don't know how to catch Ctrl+a

I tryed something like this

    case KeyEvent.VK_CONTROL+KeyEvent.VK_A :
        System.out.println("A+CTRL");
        break;

but this code KeyEvent.VK_CONTROL+KeyEvent.VK_A returns int and maybe another key combination returns the same number

So can someone can help me

Answer 1

You can use isControlDown() method:

switch (e.getKeyCode())
{
        case KeyEvent.VK_A :
            if(e.isControlDown())
               System.out.println("A and Ctrl are pressed.");
            else
                System.out.println("Only A is pressed");
            break;
        ...
}
