32 *
33 * Test Description: Check if TRANSLUCENT Translucency type is supported on the
34 * current platform. Proceed if supported. Show a window which contains an
35 * awt Choice and set with opacity less than 1.0. Another Window having a
36 * canvas component drawn with an image can be used as the background for
37 * the test window. Click on the ComboBox to show the drop down. Check if
38 * the drop down appears translucent. Repeat this for Window, Dialog and
39 * Frame.
40 * Expected Result: If TRANSLUCENT Translucency type is supported, the drop down
41 * should appear translucent.
