    • run

      public void run()
      Specified by:

    • getSingleTabPreviewImage

      protected void getSingleTabPreviewImage(JTabbedPane tabPane, TabPreviewPainter previewPainter, TabPreviewThread.TabPreviewInfo previewInfo, int tabIndex)
      Computes and offers the preview thumbnail for a single tab.
      Parameters:
      tabPane - Tabbed pane.
      previewPainter - Tab preview painter.
      previewInfo - Preview info.
      tabIndex - Index of the tab to preview.

    • 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 (see TabOverviewDialog).
      Parameters:
      previewInfo - Tab preview info.

    • cancelTabPreviewRequests

      public void cancelTabPreviewRequests(Object initiator)
