Proceed if they are supported. Create a window 33 * with some components in it, make window undecorated, apply translucent 34 * background of 0 and have a gradient painted as background from 35 * fully-transparent to fully-opaque in componentResized listener. Drag and 36 * resize the window using AWT Robot and verify that translucency is 37 * correctly applied with pixels checking. Make the window appear on top of 38 * a known background. Repeat this for JWindow, JDialog, JFrame. 39 * Expected Result: If PERPIXEL_TRANSLUCENT translucency type is supported, 40 * the window should appear as specified with the translucency. Only window 41 * background should be translucent, all the controls should be opaque. 42 * @author mrkam 43 * @library ../../../../lib/testlibrary 44 * @build Common ExtendedRobot 45 * @run main PerPixelTranslucentGradient 46 */ 47 48 public class PerPixelTranslucentGradient extends Common { 49 50 public static void main(String[] ignored) throws Exception { 51 if (checkTranslucencyMode(GraphicsDevice.WindowTranslucency.PERPIXEL_TRANSLUCENT)) 52 for (Class<Window> windowClass: WINDOWS_TO_TEST) 53 new PerPixelTranslucentGradient(windowClass).doTest(); 54 } 55 56 public PerPixelTranslucentGradient(Class windowClass) throws Exception { 57 super(windowClass, 1.0f, 0f, true); 58 } 59 60 public void doTest() throws Exception { 61 robot.waitForIdle(delay); 62 checkTranslucent(); 63 } 64 65 @Override 66 public void applyShape() { 67 gradientWidth = window.getWidth(); 68 gradientHeight = window.getHeight(); 69 } 70 }
