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