Java obtains the scroll wheel press event

The scroll wheel clicking event and mouse clicking event are in the mouselistener.

When the wheel is pressed, the original method is as follows:

Public void mouseclicked (mouseevent e) {int modifiers = E. getmodifiers (); If (modifiers & inputevent. button2_mask) = inputevent. button2_mask) {system. out. println ("middle button click ");}}

Of course, you can use swingutilities.

Public void mouseclicked (mouseevent e) {If (swingutilities. ismiddlemousebutton (E) {system. Out. println ("middle button click ");}}
