How to check if and which mouse button is pressed in Swing

How can I check if currently any mouse button is pressed and if so, which one it is?

The thing is that I need to use this kind of information in MouseListener.mouseEntered(). I checked MouseEvent but I could not find the method which would help me.

The getButton() method seems to only return value if there has been change in buttons' state.

Is there a way to find this out without manually keeping track of this somehow vie MouseListener.mousePressed()/mouseReleased() methods.

    Presumably you want to invoke specific code depending on the button pressed so you can do something like:

    if (SwingUtilities.isLeftMouseButton(...))
   // do something
