NAME

UI::Dialog::Backend::GDialog - backend for the antiquated GNOME dialog variant.

SYNOPSIS

use UI::Dialog::Backend::GDialog;
my $d = new UI::Dialog::Backend::GDialog ( backtitle => 'Demo',
                                           title => 'Default' );

$d->msgbox( title => 'Welcome!', text => 'Welcome one and all!' );

ABSTRACT

UI::Dialog::Backend::GDialog is the UI::Dialog backend for the antiquated GNOME dialog variant. While this module is used through UI::Dialog or any other loader module only the compatible methods are ever accessible. However, when using this module directly in your application (as in the SYNOPSIS example) you are given access to all the options and features of the real gdialog(1) application.

DESCRIPTION

GDialog is being phased out by the much more satisfying Zenity, but we support it's usage via this backend anyways!

EXPORT

    None

INHERITS

    UI::Dialog::Backend

CONSTRUCTOR

new( @options )

EXAMPLE
    my $d = new( title => 'Default Title', backtitle => 'Backtitle',
             width => 65, height => 20, listheight => 5 );
DESCRIPTION

    This is the Class Constructor method. It accepts a list of key => value pairs and uses them as the defaults when interacting with the various widgets.

RETURNS

    A blessed object reference of the UI::Dialog::Backend::GDialog class.

OPTIONS

The (...)'s after each option indicate the default for the option. An * denotes support by all the widget methods on a per-use policy defaulting to the values decided during object creation.

debug = 0,1,2 (0)
literal = 0,1 (0)
backtitle = "backtitle" ('') *
title = "title" ('') *
height = \d+ (0) *
width = \d+ (0) *
beepbefore = 0,1 (0) *
beepafter = 0,1 (0) *

WIDGET METHODS

yesno( )

EXAMPLE
    if ($d->yesno( text => 'A binary type question?') ) {
    # user pressed yes
} else {
    # user pressed no or cancel
}
DESCRIPTION

    Present the end user with a message box that has two buttons, yes and no.

RETURNS

    TRUE (1) for a response of YES or FALSE (0) for anything else.

msgbox( )

EXAMPLE
    $d->msgbox( text => 'A simple message' );
DESCRIPTION

    Pesent the end user with a message box that has an OK button.

RETURNS

    TRUE (1) for a response of OK or FALSE (0) for anything else.

infobox( )

EXAMPLE
    $d->infobox( text => 'A simple 6 second message.', timeout => 6000 );
DESCRIPTION

    Pesent the end user with a message box for a limited duration of time. The timeout is specified in thousandths of a second, ie: 1000 = 1 second.

RETURNS

    TRUE (1) for a response of OK or FALSE (0) for anything else.

password( )

EXAMPLE
    my $string = $d->password( text => 'Enter some (hidden) text.' );
DESCRIPTION

    Present the end user with a text input field that doesn't reveal the input (except to the script) and a message. GDialog does not actually support a (hidden input text field) inputbox other than the plain one.

    UI::Dialog::Backend::GDialog instead warns the user that their password will be visible and presents them with a plain inputbox.

    Future versions of this module will use gnome-ssh-askpass or x11-ssh-askpass instead of the plain text widget. The end user will be notified that the ssh-askpass program is going to ask them for their password instead of the regular inputbox().

    The lack of a proper password box for gdialog is my first reason for being thankful that zenity(1) is so 'now' and gdialog is being left back in 'then'!

RETURNS

    a SCALAR if the response is OK and FALSE (0) for anything else.

inputbox( )

EXAMPLE
    my $string = $d->inputbox( text => 'Please enter some text...',
                           entry => 'this is the input field' );
DESCRIPTION

    Present the end user with a text input field and a message.

RETURNS

    a SCALAR if the response is OK and FALSE (0) for anything else.

textbox( )

EXAMPLE
    $d->textbox( path => '/path/to/a/text/file' );
DESCRIPTION

    Present the end user with a simple scrolling box containing the contents of the given text file.

RETURNS

    TRUE (1) if the response is OK and FALSE (0) for anything else.

EXAMPLE
    my $selection1 = $d->menu( text => 'Select one:',
                           list => [ 'tag1', 'item1',
                                     'tag2', 'item2',
                                     'tag3', 'item3' ]
                         );
DESCRIPTION

    Present the user with a selectable list.

RETURNS

    a SCALAR of the chosen tag if the response is OK and FALSE (0) for anything else.

checklist( )

EXAMPLE
    my @selection = $d->checklist( text => 'Select one:',
                               list => [ 'tag1', [ 'item1', 0 ],
                                         'tag2', [ 'item2', 1 ],
                                         'tag3', [ 'item3', 1 ] ]
                             );
DESCRIPTION

    Present the user with a selectable checklist.

RETURNS

    an ARRAY of the chosen tags if the response is OK and FALSE (0) for anything else.

radiolist( )

EXAMPLE
    my $selection = $d->radiolist( text => 'Select one:',
                               list => [ 'tag1', [ 'item1', 0 ],
                                         'tag2', [ 'item2', 1 ],
                                         'tag3', [ 'item3', 0 ] ]
                             );
DESCRIPTION

    Present the user with a selectable radiolist.

RETURNS

    a SCALAR of the chosen tag if the response is OK and FALSE (0) for anything else.

fselect( )

EXAMPLE
    my $text = $d->fselect( path => '/path/to/a/file/or/directory' );
DESCRIPTION

    a SCALAR if the response is OK and FALSE (0) for anything else.

dselect( )

EXAMPLE
    my $text = $d->dselect( path => '/path/to/a/directory' );
DESCRIPTION

    Present the user with a file selection widget preset with the given path. Unlike fselect() this widget will only return a directory selection.

RETURNS

    a SCALAR if the response is OK and FALSE (0) for anything else.

gauge_start( )

EXAMPLE
    $d->gauge_start( text => 'gauge...', percentage => 1 );
DESCRIPTION

    Display a meter bar to the user. This get's the widget realized but requires the use of the other gauge_*() methods for functionality.

RETURNS

    TRUE (1) if the widget loaded fine and FALSE (0) for anything else.

gauge_inc( )

EXAMPLE
    $d->gauge_inc( 1 );
DESCRIPTION

    Increment the meter by the given amount.

RETURNS

    TRUE (1) if the widget incremented fine and FALSE (0) for anything else.

gauge_set( )

EXAMPLE
    $d->gauge_set( 99 );
DESCRIPTION

    Set the meter bar to the given amount.

RETURNS

    TRUE (1) if the widget set fine and FALSE (0) for anything else.

gauge_end( )

EXAMPLE
    $d->gauge_end();
DESCRIPTION

    End the meter bar widget process. One of the flaws with gdialog is that the gauge widget does not close properly and requies the end user to close the gauge window when 100% has been reached. This is the second reason why I'm glad gdialog is going the way of the dodo.

RETURNS

    TRUE (1) if the widget closed fine and FALSE (0) for anything else.
