# Registering Workspace Actions

Using `Gio.Action` is a convenient way to attach actions to the workspace that contain state. For example, maybe for use by a button that should be insensitive when it cannot be used. Additionally, actions registered on the workspace can be activated using the command bar plugin.

Registering an action on the workspace

    import gi

    from gi.repository import GObject
    from gi.repository import Gio
    from gi.repository import Ide

    class MyWorkspaceAddin(GObject.Object, Ide.WorkspaceAddin):

        def do_load(self, workspace):
            action = Gio.SimpleAction.new('hello', None)
            action.connect('activate', self.hello_activate)
            workspace.add_action(action)

            # If you have a lot of actions to add, you might
            # consider creating an action group.
            group = Gio.SimpleActionGroup.new()
            group.add_action(action)
            workspace.insert_action_group('my-actions', group)

        def do_unload(self, workspace):
            workspace.remove_action('hello')

            # And if you used an action group
            workspace.insert_action_group('my-actions', None)

        def hello_activate(self, action, param):
            print('Hello activated!')

This adds a new action named `hello` to the workspace. It can be connected to widgets by using the `win.hello` action-name. Additionally, you can call the action with `hello` from the command bar.

To toggle whether or not the action can be activated, set the `Gio.SimpleAction:enabled` property.
