Capturing right-click from mouse in AWT

(Originally posted in JFC/Swing/AWT forum):
Can someone please nudge me in the right direction? I can't figure out how the BUTTON_MASK is supposed to
work, and the isPopupTrigger() method in the MouseEvent object doesn't appear to register properly in my
application.
My purpose is to devise a popup help system when a user right-clicks on a component in the GUI.
Thanks for your help.

Hi Scott,
Nudge, nudge ...

Manfred, thanks for the nudge. However, I can never get the isPopupTrigger() to return true. If I place an else construct after each isPopupTrigger(), the else executes 100% of the time, regardless of which mouse button I press. This behavior is true on both NT and W98.
Is there a way to trap for a right mouse button click besides using isPopupTrigger()?

Play with this:

Of course you can get rid of the KeyListener stuff, it was just already in there.

Ah, thanks Cindy. The e.getModifiers() is a method I never came across (probably because I wasn't looking in the right place). I haven't tried this code, but it looks like it might do the trick.

Hi Scott,
If you use Cindy's method in your application you should be aware that not all menu popups are registered to the right mouse button. It is usually the case for a right-handed setup mouse but for a left-handed setup mouse it will be backwards (usually left mouse button). That is the reason for isPopupTrigger() method.
The popup trigger is usually set in a control panel on Windows (try mouse) ... That might be your problem ...
Regards,
Manfred.

Manfred, my popup trigger is set to the right mouse button on my system. But that actually isn't the problem, since no matter which mouse button I click, the isPopupTrigger() is returning false, both at work and at home (so it's probably not a system-specific thing). The BUTTON_MASK modifier at least is being captured properly, so I have something to react to (though I realize that this is prejudicial against left-handed mouse users).
Now if only I could figure out how to get the underlying MouseAdapter-enabled panel to intercept the MouseClick event rather than the individual components it contains...
