Description
 The Fl_Hold_Browser class is a subclass of Fl_Browser
 which lets the user select a single item, or no items by clicking on 
the empty space.  As long as the mouse button is held down the item 
pointed to by it is highlighted, and this highlighting remains on when 
the mouse button is released. Normally the callback is done when the 
user releases the mouse, but you can change this with when(). 
See Fl_Browser for 
methods to add and remove lines from the browser. 
Methods
 Creates a new Fl_Hold_Browser widget using the given 
position, size, and label string. The default boxtype is FL_DOWN_BOX
. 
 The destructor also deletes all the items in the list. 
 Same as value(0). 
 You can use these for compatibility with 
Fl_Multi_Browser. If you turn on the selection of more 
than one line the results are unpredictable. 
 Set or get which line is selected.  This returns zero if no line is 
selected, so be aware that this can happen in a callback.
