QML Package ElementPackage provides a collection of named items. More... Attached Properties
Detailed DescriptionThe Package class is used in conjunction with VisualDataModel to enable delegates with a shared context to be provided to multiple views. Any item within a Package may be assigned a name via the Package.name attached property. The example below creates a Package containing two named items; list and grid. The third element in the package (the Rectangle) is parented to whichever delegate it should appear in. This allows an item to move between views. Package { Text { id: listDelegate; width: 200; height: 25; text: 'Empty'; Package.name: 'list' } Text { id: gridDelegate; width: 100; height: 50; text: 'Empty'; Package.name: 'grid' } Rectangle { id: wrapper width: 200; height: 25 color: 'lightsteelblue' Text { text: display; anchors.centerIn: parent } MouseArea { anchors.fill: parent onClicked: { if (wrapper.state == 'inList') wrapper.state = 'inGrid'; else wrapper.state = 'inList'; } } state: 'inList' states: [ State { name: 'inList' ParentChange { target: wrapper; parent: listDelegate } }, State { name: 'inGrid' ParentChange { target: wrapper; parent: gridDelegate x: 0; y: 0; width: gridDelegate.width; height: gridDelegate.height } } ] transitions: [ Transition { ParentAnimation { NumberAnimation { properties: 'x,y,width,height'; duration: 300 } } } ] } } These named items are used as the delegates by the two views who reference the special VisualDataModel::parts property to select a model which provides the chosen delegate. VisualDataModel { id: visualModel delegate: Delegate {} model: myModel } ListView { width: 200; height:200 model: visualModel.parts.list } GridView { x: 200; width: 200; height:200 cellHeight: 50 model: visualModel.parts.grid } See also Package example, Photo Viewer demo, and QtDeclarative.
