| * @summary Check if a JComboBox 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 |
| * JComboBox 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 JWindow, JDialog and JFrame |
| * Expected Result: If TRANSLUCENT Translucency type is supported, the drop down |
| * should appear translucent. |
