Constructor & Destructor Documentation

◆ QQuickLabsPlatformMenuItemGroup()

QT_BEGIN_NAMESPACE QQuickLabsPlatformMenuItemGroup::QQuickLabsPlatformMenuItemGroup ( QObject * parent = nullptr )

explicit

A group for managing native menu items.

\qmltype MenuItemGroup
\inherits QtObject

! \instantiates QQuickLabsPlatformMenuItemGroup \inqmlmodule Qt.labs.platform

Since: 5.8

The MenuItemGroup groups native menu items together.

MenuItemGroup is exclusive by default. In an exclusive menu item group, only one item can be checked at any time; checking another item automatically unchecks the previously checked one. MenuItemGroup can be configured as non-exclusive, which is particularly useful for showing, hiding, enabling and disabling items together as a group.

The most straight-forward way to use MenuItemGroup is to assign a list of items.

Menu {
    id: verticalMenu
    title: qsTr("Vertical")
 
    MenuItemGroup {
        id: verticalGroup
        items: verticalMenu.items
    }
 
    MenuItem { text: qsTr("Top"); checkable: true }
    MenuItem { text: qsTr("Center"); checked: true }
    MenuItem { text: qsTr("Bottom"); checkable: true }
}

The same menu may sometimes contain items that should not be included in the same exclusive group. Such cases are best handled using the \l {MenuItem::group}{group} property.

Menu {
    id: horizontalMenu
    title: qsTr("Horizontal")
 
    MenuItemGroup {
        id: horizontalGroup
    }
 
    MenuItem {
        checked: true
        text: qsTr("Left")
        group: horizontalGroup
    }
    MenuItem {
        checkable: true
        text: qsTr("Center")
        group: horizontalGroup
    }
    MenuItem {
        text: qsTr("Right")
        checkable: true
        group: horizontalGroup
    }
 
    MenuItem { separator: true }
    MenuItem { text: qsTr("Justify"); checkable: true }
    MenuItem { text: qsTr("Absolute"); checkable: true }
}

More advanced use cases can be handled using the addItem() and removeItem() methods.
