<AWT Dev> [8] Review request for 8026476: Choice does not get mouse events if it does not have enough place for popup menu

[Alexander Zvegintsev]

Hello,

please review fix:
http://cr.openjdk.java.net/~serb/alexz/8026476/webrev.00/
for:
https://bugs.openjdk.java.net/browse/JDK-8026476

This fix places a drop-down menu above a choice component if it is not 
enough space below this component.
Since a choice component is unobscured by its drop-down menu it is able 
to receive mouse released and clicked events.

Thanks,

Alexander.
