Client property name | SubstanceLookAndFeel.WATERMARK_VISIBLE

Description | Client property name for requesting that watermark should 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).

There is special default setting for trees, tables, lists and text components. These show watermark only when this property is explicitly set to `Boolean.TRUE` on the component itself, one of its ancestors or the `UIManager`.

The screenshot below shows application frame with default watermark settings - not showing on a list and showing on a panel:

The screenshot below shows the same frame with the property set to `Boolean.TRUE` on the list and to `Boolean.FALSE` on the panel.
