Description |
Client property name for requesting that watermark should not be painted
on the component and its descendants. This property can be set either as
client property on some component or as global property on
UIManager . The value should be
either Boolean.TRUE or
Boolean.FALSE .
In order to compute whether the current watermark should be painted on
some component, the component's hierarchy is traversed bottom up. The
first component that has this property set, defines the watermark
visibility. Finally, if neither component not its ancestors define this
property, the global setting on
UIManager is checked. If there is
no global setting, the watermark is not ignored (it is painted).
