This test is designed to make sure that JTable, JTree, and JList
|
|
provide visual feedback when a DnD drag operation occurs over them.
|
|
|
|
Click on the label where it says "DRAG FROM HERE" and begin dragging.
|
|
Drag over each of the three components (JTable, JTree, JList).
|
|
While you're dragging over them, they should visually indicate the
|
|
location where a drop would occur. This visual indication may use the
|
|
selection but could be some other visual.
|
|
|
|
If above is true press PASS else press FAIL.
