Our code currently uses ATK_STATE_ENABLED to set the IsEnabled property.  Most Gtk widgets set both STATE_SENSITIVE and STATE_ENABLED based on whether the widget is sensitive, but a few widgets (toggle buttons and check menu items) also check whether the widget is "inconsistent" for STATE_ENABLED.  At-spi-sharp, like pyatspi2, caches the state set as an optimization and relies on StateChanged signals.  Since it does not receive one for STATE_ENABLED, its cache can become incorrect.

I've filed BGO#615999 for this and proposed a patch, so it should be fixed in gtk+ 2.21.1 (not sure about 2.20.1).  In the meantime, I should be able to mostly work around it in AtspiUiaSource.

Added a work-around in at-spi-sharp R155839.
(The proper fix would be in gail and is still awaiting review.)

Oops--forgot to mark fixed.
Comment 4 Feng Xia Mu 2010-04-21 07:17:52 UTC
