Hi all,
Bug: https://bugs.openjdk.java.net/browse/JDK-8173145
Webrev: http://cr.openjdk.java.net/~mcherkas/8173145/webrev.00/
The problem appears because AltProcessor doesn't reset altKeyPressed
flag when
not-alt key pressed, but event is consumed.
This situation is possible when all events consumed by key bindings. A
menubar is activated while
user expects only key binding actions.
In my test a button should be activated by alt+m mnemonic, but a menu is
activate, because
key pressed/released consumed by mnemonic combination and key typed
event is
consumed by DefaultEditorKit$DefaultDeyTypedAction that is installed for
JTextField,
as result instead of button, menu is activated.
To fix the issue I added resetting altKeyPressed flag if any non-alt key
pressed despite consuming state,
because obviously user what make some alt+[KEY] action instead of menu
activation.
Thanks,
Mikhail.
