Question

My question concerns how to handle with simultaneous mouse events with Swing.

Both a MouseMotionListener and a MouseListener are added to follow a JPanel.

I have an object whose rotation takes places according to the x and y coordinates of the mouse pointers location (implemented by mouseMoved method of MouseMotionListener).

I’ve also got a MouseListener that performs its actions according to implemented mouseReleased() method.

The object is rotating neatly according to MouseMotionListener but a problem arises when the mouse button is pressed. As the mouse is now moved the rotation stops as obviously the JPanel is now waiting the mouseReleased() method to be executed.

Any ideas what’s the best way to make these events happen simultaneously so that both the rotation according to the mouse pointers coordinates and operations according to mouseReleased() can be performed concurrently without disrupting each other?

An old article going into swing threading specifics:

Worth a read as to the whys and hows.
