|
|
* Test Description: Check if PERPIXEL_TRANSLUCENT Translucency type is supported
|
|
* on the current platform. Proceed if it is supported. Create a swing window
|
|
* with some swing components in it and a transparent background (alpha 0.0).
|
|
* Bring this window on top of a known background. Do this test for JFrame,
|
|
* JWindow and JDialog
|
|
* Expected Result: Only the components present in the window must be shown. Other
|
|
* areas of the window must be transparent so that the background shows
