Proceed if they are supported. Create a window 34 * with some components in it, make window undecorated, apply translucent 35 * background of 0 and have a gradient painted as background from 36 * fully-transparent to fully-opaque in componentResized listener. Drag and 37 * resize the window using AWT Robot and verify that translucency is 38 * correctly applied with pixels checking. Make the window appear on top of 39 * a known background. Repeat this for JWindow, JDialog, JFrame. 40 * Expected Result: If PERPIXEL_TRANSLUCENT translucency type is supported, 41 * the window should appear as specified with the translucency. Only window 42 * background should be translucent, all the controls should be opaque. 43 * @author mrkam 44 * @library /lib/client 45 * @build Common ExtendedRobot 46 * @run main PerPixelTranslucentGradient 47 * @run main/othervm -Dsun.java2d.uiScale=1.5 PerPixelTranslucentGradient 48 */ 49 50 public class PerPixelTranslucentGradient extends Common { 51 main(String[] ignored)52 public static void main(String[] ignored) throws Exception { 53 if (checkTranslucencyMode(GraphicsDevice.WindowTranslucency.PERPIXEL_TRANSLUCENT)) 54 for (Class<Window> windowClass: WINDOWS_TO_TEST) 55 new PerPixelTranslucentGradient(windowClass).doTest(); 56 } 57 PerPixelTranslucentGradient(Class windowClass)58 public PerPixelTranslucentGradient(Class windowClass) throws Exception { 59 super(windowClass, 1.0f, 0f, true); 60 } 61 doTest()62 public void doTest() throws Exception { 63 robot.waitForIdle(delay); 64 checkTranslucent(); 65 } 66 67 @Override applyShape()68 public void applyShape() { 69 gradientWidth = window.getWidth(); 70 gradientHeight = window.getHeight(); 71 } 72 } 73
