      the created content service.

    • runDeferredLayouts

      public static void runDeferredLayouts(org.eclipse.swt.widgets.Display display)
      Runs deferred layout for the given display. Use it as a workaround for the following Eclipse layout bug:
      1. User presses the mouse button on Navigator to select something in it. Eclipse makes call to Shell.setLayoutDeferred(true) to reduce the flickering of the toolbar while updating toolbar actions.
      2. While updating actions Eclipse also calls layout procedure with SWT.DEFER flag, that increases the number of deferred layout operations for the Shell.
      3. After that, subsequent call to Shell.setLayoutDeferred(false) will not trigger the replay of deferred layout operations since there were calls with SWT.DEFER flag. Such calls are replayed internally by the Display.runDeferredLayouts() on each attempt to process Display event queue events.
      4. DND subsystem disables the event processing while the mouse button is down. So the Display.runDeferredLayouts() call will not be made until user will release the mouse button.
      5. Eclipse totally disables the layout processing while user holds the mouse button down.
      Parameters:
      display - display to run deferred layouts for.
