FLTK::HelpView - Basic HTML viewer
Most HTML 2.0 elements are supported, as well as a primitive implementation of tables. GIF, JPEG, and PNG images are displayed inline.
my $ok = $helpview->find( $string, $start );
Find the specified string in the current help text. This is a plain text search.
0 on success.
-1 on failure.
$helpview->leftline( $col );
Set the left position.
my $col = $helpview->leftline( );
Get the left position.
my $result = $helpview->load( $filename );
Load the specified file.
0 on success and
-1 on error
my $hv = $helpview->new( $x, $y, $w, $h, $label );
Creates a new HelpView.
$helpview->topline( $string );
Sets the top line to the named line.
$helpview->topline( $index );
Sets the top line to the indexth line.
my $num = $helpview->topline( );
Retusn the index of the current top line.
$helpview->value( $string );
Set the help text directly.
my $string = $helpview->value( );
Get the current help text.
HelpView may not be subclassed like every other widget in FLTK because fltk::HelpView::draw( ) and fltk::HelpView::handle( ...
) are private.
If I subclass them,
I lose basic functionality because I cannot access those functions from a child class.
This is a "bug" and I'll report it when I have the time.
