Hello Swing team,
Could you please review the fix for jdk9:
bug: https://bugs.openjdk.java.net/browse/JDK-8136998
webrev: http://cr.openjdk.java.net/~aivanov/8136998/jdk9/webrev.00/
Problem description:
When JComboBox is added into a JScrollPane, scroll pane is not scrolled
by mouse wheel if mouse over JComboBox.
The fix to https://bugs.openjdk.java.net/browse/JDK-8033069 added
MouseWheelListener to JComboBox, and combo box consumes MOUSE_WHEEL
events therefore these events do not reach JScrollPane beneath JComboBox.
The fix:
Remove MouseWheelListener from JComboBox. To prevent the combo box popup
from being closed by rotating mouse wheel over the JComboBox,
MouseWheelListener is added when the popup is about to be displayed and
is removed when the popup is about to be hidden.
Regards,
Alexey
