| * Test Application for demonstrating the <code>--preserveSplashScreen</code> |
| * Pivot startup property.<br/> |
| * |
| * This desktop application simulates some task processing while a SplashScreen |
| * is displayed, before forcing the Pivot host window to become visible which in |
| * turn hides the SplashScreen.<br/>The progress of the simulated tasks is shown |
| * using a Pivot Meter that paints onto the SplashScreen as the tasks |
| * 'complete'. <br/><br/> |
| * |
| * If <code>--preserveSplashScreen</code> is set to <code>true</code> and there |
| * is a SplashScreen, DesktopApplicationContext will not make the Pivot host |
| * window visible until |
| * {@link DesktopApplicationContext#replaceSplashScreen(Display) |
| * replaceSplashScreen(Display)} is called.<br/><br/> |
| * |
| * If <code>--preserveSplashScreen</code> is set to <code>false</code>, is not |
| * supplied, or there is no SplashScreen, DesktopApplicationContext make the |
| * Pivot host window visible as normal. Any calls to |
| * {@link DesktopApplicationContext#replaceSplashScreen(Display) |
| * replaceSplashScreen(Display)} will have no effect.<br/><br/> |
