## Detailed Description

ContextMenu can be attached to any item in order to show a context menu upon a platform-specific event, such as a right click or the context menu key.

     Pane {
         anchors.fill: parent

         ContextMenu.menu: Menu {
             MenuItem {
                 text: qsTr("Eat Tomato")
                 onTriggered: { /* ... */ }
             }
             MenuItem {
                 text: qsTr("Throw Tomato")
                 onTriggered: { /* ... */ }
             }
             MenuItem {
                 text: qsTr("Squash Tomato")
                 onTriggered: { /* ... */ }
             }
         }
     }

## Sharing context menus

It's possible to share a Menu amongst several attached context menu objects. This allows reusing a single Menu when the items that need context menus have data in common. For example:

     pragma ComponentBehavior: Bound

     import QtQuick
     import QtQuick.Controls.Basic
     import QtQuick.Templates as T

     ApplicationWindow {
         width: 600
         height: 400
         visible: true

         component Tomato: Label {
             id: tomato
             objectName: text
             horizontalAlignment: Label.AlignHCenter
             verticalAlignment: Label.AlignVCenter
             width: Math.max(200, contentWidth * 1.5, contentWidth * 1.5)
             height: width
             color: skinColor

             function eat() { print("Ate " + text) }
             function ditch() { print("Threw " + text) }
             function squash() { print("Squashed " + text) }

             property color skinColor: "tomato"

             background: Rectangle {
                 color: tomato.skinColor
                 radius: width / 2
             }

             ContextMenu.menu: contextMenu
         }

         Menu {
             id: contextMenu

             readonly property Tomato triggerItem: parent as Tomato
             readonly property string triggerItemText: triggerItem?.text ?? ""

             MenuItem {
                 text: qsTr("Eat %1").arg(contextMenu.triggerItemText)
                 onTriggered: contextMenu.triggerItem.eat()
             }
             MenuItem {
                 text: qsTr("Throw %1").arg(contextMenu.triggerItemText)
                 onTriggered: contextMenu.triggerItem.ditch()
             }
             MenuItem {
                 text: qsTr("Squash %1").arg(contextMenu.triggerItemText)
                 onTriggered: contextMenu.triggerItem.squash()
             }
         }

         Row {
             anchors.centerIn: parent

             Tomato {
                 text: qsTr("tomato")
             }

             Tomato {
                 text: qsTr("really ripe tomato")
                 skinColor: "maroon"
             }
         }
     }

## Performance

ContextMenu lazily creates its `Menu` only when it's requested. If it wasn't for this optimization, the `Menu` would be created when the containing component is being loaded, which is typically at application startup.

It is recommended not to give the `Menu` assigned to ContextMenu's menu property an id when it's defined where it's assigned. Doing so prevents this optimization. For example:

     Pane {
         anchors.fill: parent

         ContextMenu.menu: Menu {
             // This prevents lazy creation of the Menu.
             id: myMenu

             // ...
         }
     }

The example in the Sharing context menus section works because the `Menu` is defined separately from its assignment.

## Interaction with other menus

If a `Menu` is opened via e.g. a TapHandler or other means, ContextMenu will not open at the same time. This allows legacy applications that were written before ContextMenu was introduced to continue working as expected.

## Property Documentation

menu : Menu

This property holds the context menu that will be opened. It can be set to any Menu object.

Note: The Menu assigned to this property cannot be given an id. See Sharing context menus for more information.

## Signal Documentation

requested(point position)

This signal is emitted when a context menu is requested.

If it was requested by a right mouse button click, position gives the position of the click relative to the parent.

The example below shows how to programmatically open a context menu:

     Button {
         id: button
         text: qsTr("Click me!")
         ContextMenu.onRequested: position => {
             const menu = buttonMenu.createObject(button)
             menu.popup(position)
         }
     }

     Component {
         id: buttonMenu
         Menu {
             MenuItem { text: qsTr("Open") }
         }
     }

If no menu is set, but this signal is connected, the context menu event will be accepted and will not propagate.

Note: The corresponding handler is `onRequested`.
