1. Click on the 'Painting Glitch Test' window and select from
|
|
its menu a content type (text, gradient, fill,
|
|
AWT components, Swing components etc.).
|
|
2. Select 'Modal Dialog...' to create a dialog.
|
|
3. Drag the dialog over the content very fast
|
|
for 10 seconds or so - make sure you
|
|
keep dragging while the content is painting.
|
|
4. Verify that the area exposed by the drag (the damaged regions)
|
|
always update properly no white areas or bits of the dialog
|
|
should be left after the drag operation is
|
|
completed (i.e. after you let go of the mouse).
|
|
5. Repeat for all other content types.
|
|
6. If for any content type the damaged dialog is not properly
|
|
repainted press Fail. Otherwise press Pass.
