Get key combination code of multiple keys

Question

I want to ask you can I get key code combination of multiple keys. For example I can get the key code from this example:

<         


        

Answer 1

No, the handled keyEvent has only one main KeyCode, for example this code

public void handle(KeyEvent event) {
    if (event.getCode() == KeyCode.TAB) { 
    }
}

will handle TAB, ALT + TAB, or CTRL + TAB etc. If you only interested in CTRL + TAB, you have 2 choices:
1) using isControlDown()

public void handle(KeyEvent event) {
    if (event.getCode() == KeyCode.TAB && event.isControlDown()) { 
    }
}

2) using KeyCodeCombination

final KeyCombination kb = new KeyCodeCombination(KeyCode.TAB, KeyCombination.CONTROL_DOWN);
...
...
public void handle(KeyEvent event) {
    if (kb.match(event)) { 
    }
}
