<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>
