DESCRIPTION
This is a megawidget to display a program window. I was tired of creating menues, prefs dialogues, about dialogues,... for every new application..... I searched for a generic way wrote this module. This modules stores the main window's font, size and position and embodies the fucntions from the Tk::Mainwindow module.
WIDGET-SPECIFIC OPTIONS
-app => $Applikation_Name
Set a Application name, default is Program
-set_icon => $Path_to_icon_image
Set a Application Icon, please give this in 32x32 pixel and in gif format.
-cfg => $path_to_config_file;
Set the path to the config file, default:
$HOME/.$Application_Name.cfg
-add_prefs => $arrey_ref_more_prefs or $path_to_cfg_file;
This allows to include your Preferences into default:
-add_prefs => [
'Tools',
['acrobat', '=s', '/usr/local/bin/acroread',
{ 'subtype' => 'file',
'help' => 'Path to acrobat reader.'
} ],
],
Also you can use a config file as parameter:
-add_prefs => $path_to_cfg_file;
-set_logo => $image_file;
One logo for one program This picture will be use from the Splash and About Method. Carefully, if not defined in the Splash then an error is returned.
-help => $pod_file;
This includes a Help function as a topwindow with Poddisplay. Look for more Information on Tk::Pod. Default is the program source ($0).
METHODS
These are the methods you can use with this Widget.
$top->init_prefs( $prefs );
This will initialize the user or default preferences. It returns a reference to the options hash. More information about the prefsobject look at Tk::Getopt from slaven. The Program which uses this Module has a configuration dialog in tk and on the commandline with the following standard options:
- Geometry: Save the geometry (size and position) from mainwindow.
- Font: Save the font from mainwindow.
- Color: Save the color from mainwindow.
In the Standard menu you find the preferences dialog under File - Prefs.
I.E.:
my $opt = $top->init_prefs();
print $opt->{Geometry};
....
$top->prefs();
Display the Configuration dialog.
$top->set_icon( $path_to_icon );
Set a new Icon at runtime.
$top->set_logo( $path_to_logo );
Set a new Logo at runtime.
$top->init_menu( $menuitems );
Initialize the user or default Menu and return the Menuobject. You can set your own menu with the first parameter. the other (clever) way: you add your own menu to the standart menu. I.E:
# New menu item
my $edit_menu = $mw->Menu();
$edit_menu->command(-label => '~Copy', -command => sub{ print "Choice Copy\n" });
$edit_menu->command(-label => '~Cut', -command => sub{ print "Choice Cut\n" });
# ....
my $menu = $mw->init_menu();
$menu->insert(1, 'cascade', -label => 'Edit', -menu => $edit_menu);
$top->splash( $milliseconds );
Display the Splashscreen for (optional) x milliseconds. The -set_logo option is required to initialize with a Picture. Also you can use this as Switch, without any Parameter:
$top->splash(); # Splash on
....
working
...
$top->splash(); # Splash off
$top->config( Name, $value );
You have data from your widgets and you will make this data persistent? No Problem:
$top->config( 'Info', $new_ref_with_importand_informations )
...
my $info = $top->config( 'Info' );
$top->add_status( $name, \$value or \$widget );
Display a Status text field or a widget in the status bar, if you first call add_status then will Tk::Program create a status bar:
my $widget = $mw->init_status()->Entry();
$widget->insert('end', 'Exampletext ....');
my $status = {
One => 'Status one',
Full => 'Full sentence ....',
Time => sprintf('%d seconds', time),
Widget => $widget,
};
# Add Status fields
foreach (sort keys %$status) {
$mw->add_status($_, \$status->{$_}) ;
}
$top->add_toolar( $typ, $options );
Display the ToolbarWidget at first call and include the Widget ($typ) with options ($options):
# Add Button to toolbar
$mw->add_toolbar('Button',
-text => 'Button',
-tip => 'tool tip',
-command => sub { print "hi\n" });
$mw->add_toolbar('Label', -text => 'Label');
$mw->add_toolbar('separator');
Look for more Information on Tk::ToolBar.
$top->exit( );
Close the program, you can include your code (before call the exit command) with:
...
$mw->configure(-exit_cb => sub{ .... })
$mw->exit;
