Tk::Text::Viewer - Simple Text Viewer

SYNOPSIS

    use Tk;
    use Tk::Text::Viewer;
    .....
    my $mw = MainWindow->new;
    my $t1 = $mw->Scrolled('Viewer', -wrap => 'none'......);
    $t1->LabelText("Search:");# Change label text
    or:
    my $t1 = $mw->Viewer()->pack();
    .....

DESCRIPTION

Tk::Text::Viewer IS A text widget that can display text files under TK. It enable the user to search text and navigate in a Text widget. The reason for creating this module is that it doesn't require downloading of modules other that Tk; Look for widget options in Tk::Text.

A separate viewer.pl program is included that can be used as a stand alone file browser.

WIDGET METHODS

The Viewer widget also inherits all the methods provided by the generic Tk::Widget and Tk::Text classes.

The following additional method is available for viewer widgets:

$text_view->Load($filename)

Load file into the text widget.

$text_view->LabelConfig(string or hash ref)
  • $text_view->LabelConfig("Search:")

    Change label for the search entry field. You might want to change this label if the widget is used in a non English application.

  • $text_view->LabelConfig("-cursor=> 'dot'")

    Change one label widget option (for example cursor).

  • $text_view->LabelConfig({text=>'Find:',-cursor=>'dot',...})

    Replace label widget options with your own set of options. Do not change the 'Name' option of the label widget. See Tk::Label for valid options

$text_view->EntryConfig(string or hash ref)

Change the entry widget options. Read LabelConfig for information about parameters. See Tk::Entry for valid options.
