Java Mouse Event Right Click

问题:

On my three button mouse MouseEvent.BUTTON2= Middle Click and MouseEvent.BUTTON3 = Right Click.

Is this the case on a two button mouse?

Thanks

To avoid any ambiguity, use the utilities methods from SwingUtilities :

SwingUtilities.isLeftMouseButton(MouseEvent anEvent) SwingUtilities.isRightMouseButton(MouseEvent anEvent) SwingUtilities.isMiddleMouseButton(MouseEvent anEvent)

Yes, take a look at this thread which talks about the differences between platforms.

BUTTON3 is the same across all platforms, being equal to the right mouse button. BUTTON2 is simply ignored if the middle button does not exist.

I've seen

anEvent.isPopupTrigger() 

be used before. I'm fairly new to Java so I'm happy to hear thoughts about this approach :)
