queueTabPreviewRequest
public void queueTabPreviewRequest(TabPreviewThread.TabPreviewInfo previewInfo)
Queues the request to preview one or all tabs in the specified tabbed pane. Once the request is queued, the thread will pick it up from the queue (in at most 500 milliseconds in the current implementation) and start processing it. For each tab (if all tabs were requested to be previewed), the preview thumbnail will be offered to the relevant callback. This allows to maintain the interactivity of the application while generating the preview thumbnails for the tab overview dialog (seeTabOverviewDialog
).- Parameters:
previewInfo
- Tab preview info.
-
cancelTabPreviewRequests
public void cancelTabPreviewRequests(Object initiator)
Cancels all tab preview requests that were initiated by the specified initiator.- Parameters:

protected void requestStop()
Description copied from class:TrackableThread
Issues a stop request onthis
thread.- Specified by:

-
getInstance
public static TabPreviewThread getInstance()
Returns the singleton instance of the tab preview thread.- Returns:
- The singleton instance of the tab preview thread.
-
