/**
* Factory to create, configure and show application consistent
* search and find widgets.
*
* Typically a shared JXFindBar is used for incremental search, while
* a shared JXFindPanel is used for batch search. This implementation
*
*
* - JXFindBar - adds and shows it in the target's toplevel container's
* toolbar (assuming a JXRootPane)
*
- JXFindPanel - creates a JXDialog, adds and shows the findPanel in the
* Dialog
*
*
*
* PENDING: JW - update (?) views/wiring on focus change. Started brute force -
* stop searching. This looks extreme confusing for findBars added to ToolBars
* which are empty except for the findbar. Weird problem if triggered from
* menu - find widget disappears after having been shown for an instance.
* Where's the focus?
*
*
* PENDING: add methods to return JXSearchPanels (for use by PatternMatchers).
