The HelpDialog widget displays HTML files and allows the
user to click on links to do navigation. Currently most HTML 2.0 elements
are supported except for images. Table support is primitive at best.
Even so, it provides enough capabilities to be used for on-line help and other HTML applications.
The HelpDialog widget combines a dialog window, history buttons,
text size buttons, and the HelpView widget to provide an embedded
HTML file viewing dialog.
To use the HelpDialog widget in your program, do:
#include "HelpDialog.h"
...
{
HelpDialog help();
help.load("filename.html");
help.show();
while (help.visible())
Fl::wait();
}
