<AWT Dev> [9] Review request for 8050478: [macosx] Cursor not updating correctly after closing a modal dialog

[Dmitry Markov]

Hi Sergey,

Thank you for the review.

Actually the event is generated when the dialog is displayed, but it is discarded in deliverJavaMouseEvent() function (see AWTView.m) since the window is already disabled. When we are going to show a modal dialog we disable/block previously displayed windows via setModalBlocked() method. So we have to generate and send MouseExited event to the window before it is disabled/blocked by the modal dialog.

Thanks,
Dmitry
