JList should provide visual feedback when a DnD drag operation is
|
|
occurring over it. This test is to check that it provides the
|
|
feedback about the drop location correctly.
|
|
|
|
Click on the label where it says "DRAG FROM HERE" and begin dragging.
|
|
Drag over each column in each of the three JLists and make sure that
|
|
the drop location indicated is appropriate for the mouse location. For
|
|
instance, if the mouse is in the first column, the drop location should
|
|
also be indicated in that first column.
|

If above is true press PASS else press FAIL.
