+/*!
+ \qmltype Action
+ \instantiates QQuickAction
+ \inqmlmodule QtQuick.Controls 1.0
+ \brief Action provides an abstract user interface action that can be bound to items
+
+ In applications many common commands can be invoked via menus, toolbar buttons, and keyboard
+ shortcuts. Since the user expects each command to be performed in the same way, regardless of
+ the user interface used, it is useful to represent each command as an \e action.
+
+ An action can be bound to a menu item and a toolbar button, and it will automatically keep them in sync.
+ For example, in a word processor, if the user presses a Bold toolbar button, the Bold menu item will
+ automatically be checked.
+
+ QtQuick Controls supports actions in \l Button, \l ToolButton, and \l MenuItem.
+*/
+
+/*!
+ \qmlproperty string Action::text
+
+ Text for the action. This text will show as the button text, or
+ as title in a menu item.
+
+ Mnemonics are supported by prefixing the shortcut letter with \&.
+ For instance, \c "\&Open" will bind the \c Alt-O shortcut to the
+ \c "Open" menu item. Note that not all platforms support mnemonics.
+
+ Defaults to the empty string.
+*/
+
+/*!
+ \qmlproperty url Action::iconSource
+
+ Sets the icon file or resource url for the action. Defaults to the empty URL.
+*/
+
+/*!
+ \qmlproperty string Action::iconName
+
+ Sets the icon name for the action. This will pick the icon
+ with the given name from the current theme.
+
+ Defaults to the empty string.
+*/
+
+/*!
+ \qmlproperty string Action::tooltip
+
+ Tooltip to be shown when hovering the control bound to this action.
+ Not all controls support tooltips on all platforms, especially \l MenuItem.
+
+ Defaults to the empty string.
+*/
+
+/*!
+ \qmlproperty bool Action::enabled
+
+ Whether the action is enabled, and can be triggered. Defaults to \c true.
+
+ \sa tigger(), triggered()
+*/
+
+/*!
+ \qmlproperty bool Action::checkable
+
+ Whether the menu item can be checked, or toggled. Defaults to \c false.
+
+ \sa checked, exclusiveGroup
+*/
+
+/*!
+ \qmlproperty bool Action::checked
+
+ If the action is \l checkable, this property reflects its checked state. Defaults to \c false.
+ Its value is also false while \l checkable is false.
+
+ \sa toggled(), exclusiveGroup
+*/
+
+/*!
+ \qmlproperty ExclusiveGroup Action::exclusiveGroup
+
+ If an action is checkable, an \l ExclusiveGroup can be attached to it.
+ All the actions sharing the same exclusive group become mutually exclusive
+ selectable, meaning that only the last checked action will actually be checked.
+
+ Defaults to \c null, meaning no exclusive behavior is to be expected.
+
+ \sa checkable, checked
+*/
+
+/*!
+ \qmlproperty string Action::shortcut
+
+ Shortcut bound to the action. Defaults to the empty string.
+*/
+
+/*! \qmlsignal Action::triggered()
+
+ Emitted when either the menu item or its bound action have been activated.
+ You shouldn't need to emit this signal, use \l trigger() instead.
+*/
+
+/*! \qmlmethod Action::trigger()
+
+ Will emit the \l triggered() signal if the action is enabled. Will also emit the
+ \l toggled() signal if it is checkable.
+*/
+
+/*! \qmlsignal Action::toggled(checked)
+
+ Emitted whenever a action's \l checked property changes.
+ This usually happens at the same time as \l triggered().
