Fl_Group | +----Fl_Help_View
Fl_Help_View widget displays HTML text. Most HTML 2.0
elements are supported, as well as a primitive implementation of tables.
GIF, JPEG, and PNG images are displayed inline.
The constructor creates the
Fl_Help_View widget at the specified
position and size.
The destructor destroys the widget and frees all memory that has been allocated for the current file.
This method returns the current directory (base) path for the file in the buffer.
This method returns the current filename for the text in the buffer.
This method assigns a callback function to use when a link is
followed or a file is loaded (via
Fl_Help_View::load()) that requires a different
file or path. The callback function receives a pointer to the
Fl_Help_View widget and the URI or full pathname
for the file in question. It must return a pathname that can be
opened as a local file or NULL:
const char *fn(Fl_Widget *w, const char *uri);
The link function can be used to retrieve remote or virtual documents, returning a temporary file that contains the actual data. If the link function returns NULL, the value of the Fl_Help_View widget will remain unchanged.
If the link callback cannot handle the URI scheme, it should return the uri value unchanged or set the value() of the widget before returning NULL.
This method loads the specified file or URL.

The first two forms scroll the text to the indicated position, either with a named destination or by pixel line.
The second form returns the current top line in pixels.
The first form sets the current buffer to the string provided and reformats the text. The second form returns the current buffer contents.
