> Key: NETBEANS-1813
> URL: https://issues.apache.org/jira/browse/NETBEANS-1813
> Project: NetBeans
> Issue Type: Bug
> Reporter: Emilian Bold
> Priority: Major
> Attachments: TriggerBugAction.java,
> overlapping-showProgressDialogAndRun-bug.mov
>
>
> BaseProgressUtils.showProgressDialogAndRun shows a modal progress dialog and
> puts a translucent grey fog over the main window.
> It's possible with two overlapping progress dialogs to forever corrupt the
> main window glass pane. This glass pane is also used to show node tooltips
> (when the text is too long to fit).
> See the attached TriggerBugAction which reproduces the issue on NetBeans 8.2
> and Apache NetBeans 10.
> The explanation is simple. Each progress dialog will:
> 1. save the existing glass pane
> 2. set the grey glass pane
> 3. restore the glass pane to the saved one when the task has finished.
> If you have dialog 1 and dialog 2 the 2nd dialog will save the glass pane as
> set by dialog 1. But, if dialog 2 finishes last, it will forever set the
> glass pane to the grey glass pane.
> I've also attached a video showing how the node tooltip toggles the grey
> glass pane instead.
> This glass pane switch logic is in
> platform/progress.ui/src/org/netbeans/modules/progress/ui/AbstractWindowRunner.java
