It supports three different selection modes - +single file selection, multiple file selection, and new file selection (for +use in "save as" situations). + +<H2>Implementation</H2> + +<P>The <CODE>FileChooser</CODE> widget is based upon four classes: + +<UL> + + <LI><CODE>FileBrowser</CODE> - this is a subclass of + <CODE>Fl_Browser</CODE> that lists files in a specified directory or + all drives/mount points on a system. + + <LI><CODE>FileChooser</CODE> - this is the high-level class that + provides the dialog window and controls. + + <LI><CODE>FileIcon</CODE> - this class provides icon images for + the <CODE>FileBrowser</CODE> widget and associates + filetypes/extensions with those icon images. The current code + understands SGI ".fti" files used under IRIX and ".xpm" files + used by CDE. + + <LI><CODE>FileInput</CODE> - this is a subclass of + <CODE>Fl_Input</CODE> that remaps the Tab key. The new mapping + allows a user to move the cursor to the end of the current + selection using the Tab key (i.e. to accept filename + completion), but if there is no selection the Tab key performs + navigation instead. + +</UL> + +<P>The <CODE>FileIcon</CODE> class allows you to add icons for +individual file types.
