<H1>The Help Application (flsurf)</H1>
<P>The <CODE>HelpApp</CODE> widget provides a simple web browser application,
complete with bookmarks, proxy support, and so forth. The <CODE>flsurf</CODE>
application included with the distribution demonstrates how to use it.
<H2>Implementation</H2>
<P>The <CODE>HelpApp</CODE> widget is composed of several windows and control
widgets. The HTML viewing portion is handled by the <CODE>HelpView</CODE>
widget, while file selection is handled by the <CODE>FileChooser</CODE>
widget.
<P>HTTP access to files is handled by the <A HREF="http://www.cups.org">CUPS</A>
HTTP functions. Currently only a single file is cached, so any navigation
results in a reload.
<H2>Using the HelpApp Widget</H2>
<P>The source for <CODE>flsurf</CODE> is shown below:
<UL><PRE>
#include "HelpApp.h"
#include <FL/x.H>
int // O - Exit status
main(int argc, // I - Number of command-line arguments
char *argv[]) // I - Command-line arguments
{
HelpApp *app; // Help application
fl_open_display();
app = new HelpApp;
if (argc >= 2)
app->load(argv[1]);
app->show();
Fl::run();
delete app;
return (0);
}
</PRE></UL>
