NAME
Tk::AppWindow - An application framework based on Tk
SYNOPSIS
my $app = new Tk::AppWindow(@options,
-extensions => ['ConfigFolder'],
);
$app->MainLoop;
DESCRIPTION
An extendable application framework written in perl/Tk. The aim is maximum user configurability and ease of application building.
To get started read Tk::AppWindow::OverView and Tk::AppWindow::CookBook.
This document is a reference manual.
CONFIG VARIABLES
- Switch: -appname
-
Set the name of your application.
If this option is not specified, the name of your application will be set to the filename of your executable with the first character in upper case.
- Switch: -commands
-
Defines commands to be used in your application. It takes a paired list of command names and callbacks as parameter.
my $app = $k::AppWindw->new( -commands => [ do_something1 => ['method', $obj], do_something2 => sub { return 1 }, ], );
Only available at create time.
- Name : errorColor
- Class : ErrorColor
- Switch: -errorcolor
-
Default value '#FF0000' (red).
- Switch: -extensions
-
Specifies the list of extensions to be loaded.
my $app = Tk::AppWindow->new( -extensions => [ qw/Art ConfigFolder Daemons Help Keyboard MDI MenuBar Panels Plugins SDI Selector Settings SideBars StatusBar ToolBar/ ], );
The following order matters for the buildup of menus and bars. Only available at create time.
- Name : linkColor
- Class : LinkColor
- Switch: -linkcolor
-
Foreground color for links. Default value '#3030DF'.

Specifies the image file to be used as logo for your application. Default value is Tk::findINC('Tk/AppWindow/aw_logo.png').
- Switch: -namespace
-
Specifies an additional name space for extensions and plugins. If you set it, for example, to 'Foo::Bar', then your extensions may also live in 'Foo::Bar::Ext' and your plugins may live in 'Foo::Bar::Plugins'.
Only available at create time.
- Switch: -savegeometry
-
Default value 0. Saves the geometry on quit and loads it on start. Only works if the extension ConfigFolder is loaded.
COMMANDS
- quit
-
Calls the CmdQuit method. See there.
METHODS
- addPostConfig('Method', $obj, @options)
-
Only to be called by extensions at create time. Specifies a callback te be executed after main loop starts.
Callbacks are executed in the order they are added.
- addPreConfig(@configs)
-
Only to be called by extensions at create time. Specifies configs to the ConfigSpec method executed in Populate.
- appName($name)
-
Sets and returns the application name. Same as $app->configPut(-name => $name), or $app->configGet($name).
- balloon
-
Returns a reference to the Balloon widget.
- BalloonAttach$widget, $text
-
Attaches a balloon message to $widget.
- CanQuit
-
Returns 1. It is called when Tk::AppWindow tests all extensions if they can quit. You can overwrite it when you inherit Tk::AppWindow.
- cmdConfig(@commands)
-
$app->cmdConfig( command1 => ['SomeMethod', $obj, @options], command2 => [sub { do whatever }, @options], );
cmdConfig takes a paired list of commandnames and callback descriptions. It registers them to the commands table. After that cmdExecute can be called on them.
- cmdExecute('command_name', @options);

Looks for the callback assigned to command_name and executes it. returns the result.
- cmdExists('command_name')
-
Checks if command_name can be used as a command. Returns a boolean.
- cmdHookAfter('command_name', @callback)
-
Adds a hook to after stack of the callback associated with 'command_name'. See Tk::AppWindow::BaseClasses::Callback.
- cmdHookBefore('command_name', @callback)
-
Adds a hook to before stack of the callback associated with 'command_name'. See Tk::AppWindow::BaseClasses::Callback.
- cmdRemove('command_name')
-
Removes 'command_name' from the command stack.
- cmdUnhookAfter('command_name', @callback)
-
unhooks a hook from after stack of the callback associated with 'command_name'. See Tk::AppWindow::BaseClasses::Callback.

-
unhooks a hook from before stack of the callback associated with 'command_name'. see Tk::AppWindow::BaseClasses::Callback.
