Steps to try to reproduce this problem:
|
||||
When this test is run a window will display (Test Focus).
|
||||
Click in the text field to give it the focus (a blinking cursor
|
||||
will appear) and then move the frame with the mouse. The text field
|
||||
(component which uses a lightweight component) should still have focus.
|
||||
You should still see the blinking cursor in the text field after the
|
||||
frame has been moved. If this is the behavior that you observe, the
|
||||
test has passed, Press the Pass button. Otherwise the test has failed,
|

Press the Fail button.""";
