Un-responsive Timer
Hi I am trying to create a Timer using javax.swing.Timer that starts a mouse event after a delay of 10 seconds. More specifically, when the mouse enters the panel ("panel_1") it should start the timer and do a task in the MouseListener 'mouseEntered' method, (in this case just output the string "starting", after a delay of 10 secs. However, I do not get the desired result. The string "starting" is displayed straight away without any delay. Does anyone have any ideas? The code is below. thanks!
