NAME

       UI::Dialog::Backend::GDialog

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::Dia-
       log or any other loader module only the compatible methods are ever accessible. However, when using this module directly in your applica-
       tion (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

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

	    $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.

       menu( )

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

       DESCRIPTION

						     '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.

					   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
		 Present the user with a file selection widget preset with the given path.

       RETURNS
		 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 direc-
		 tory 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 function-
		 ality.

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

       gauge_inc( )

       EXAMPLE

		 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.
