Import Statement: import QtQuick

Group: AnchorChanges is part of qtquick-states
Detailed Description▲
The AnchorChanges type is used to modify the anchors of an item in a State.
AnchorChanges cannot be used to modify the margins on an item. For this, use PropertyChanges instead.
In the following example we change the top and bottom anchors of an item using AnchorChanges, and the top and bottom anchor margins using PropertyChanges:
import QtQuick 2.0
Rectangle {
id: window
width: 120; height: 120
color: "black"
Rectangle { id: myRect; width: 50; height: 50; color: "red" }
states: State {
name: "reanchored"
AnchorChanges {
target: myRect
anchors.top: window.top
anchors.bottom: window.bottom
}
PropertyChanges {
target: myRect
anchors.topMargin: 10
anchors.bottomMargin: 10
}
}
MouseArea { anchors.fill: parent; onClicked: window.state = "reanchored" }
}
AnchorChanges can be animated using AnchorAnimation.
//animate our anchor changes
Transition {
AnchorAnimation {}
}Changes to anchor margins can be animated using NumberAnimation.
For more information on anchors see Anchor Layouts.
