<H3>Description</H3>
This is the base class for browsers. To be useful it must be
subclassed and several virtual functions defined. The Forms-compatable
browser and the file chooser's browser are subclassed off of this.
<P>This has been designed so that the subclass has complete control
over the storage of the data, although because <TT>next()</TT> and <TT>
prev()</TT> functions are used to index, it works best as a linked list
or as a large block of characters in which the line breaks must be
searched for. </P>
<P>A great deal of work has been done so that the "height" of a data
object does not need to be determined until it is drawn. This is
useful if actually figuring out the size of an object requires
accessing image data or doing <TT>stat()</TT> on a file or doing some
other slow operation. </P>

By default you can scroll in both directions, and the scrollbars
disappear if the data will fit in the widget. has_scrollbar() changes
this based on the value of <TT>h</TT>:
