NAME

Tk::More - a 'more' or 'less' like text widget

SYNOPSIS

    use Tk::More;
    $more = $parent->More(...text widget options ...);
    $more->Load(FILENAME);

DESCRIPTION

Tk::More is a readonly text widget with additional key bindings as found in UNI* command line tools "more" or "less". As in "more" an additional status/command line is added at the bottom.

ADDITIONAL BINDINGS

Key-g or Home: goto beginning of file

Key-G or End: goto end of file

Key-f or Next: forward screen

Key-b or Prior: backward screen

Key-k or Up: up one line

Key-j or Down: down one line

Key-?: search backward

Key-n: find next match

Key-N: find previous match

Key-u: up half screen

Key-d: down half screen

OPTIONS

Name: fixedFont

Class: FixedFont

Switch: -font: Set the font of the viewer widget. This is by default a fixed font.

Name: searchCase

Class: SearchCase

Switch: -searchcase: Set if searching should be done case-insensitive. Defaults to true.

Switch: -helpcommand: Sets the command for the "h" (help) key.

METHODS

Load($file, %args)

Load $file into the widget. %args may be one of the following

-encoding => $encoding: Assume the encoding of the file to be $encoding. If none is given, then assume no encoding (which is equivalent to iso-8859-1).

AddQuitBindings: Convenience method to add the bindinds Key-q and Control-Key-q to close the Toplevel window containing this More widget.

BUGS

Besides that most of more bindings are not implemented. This bugs me most (high to low priority):

* better status line implementation

* Cursor movement: up/down move displayed area regardless where
insert cursor is

* add History, Load, Search (also as popup menu)
