How set position for Dialog in Qt Quick Controls 2 ?

[sardar]

hi
i want to use dialog in Qt Quick Controls 2 added in Qt 5.8, but for open dialog in center of page you must use x,y.
Gallery Sample :

    Dialog {
        id: aboutDialog
        modal: true
        focus: true
        x: (window.width - width) / 2
        y: window.height / 6
        width: Math.min(window.width, window.height) / 3 * 2
        contentHeight: aboutColumn.height

        Column {
            id: aboutColumn
            spacing: 20

            Label {
                text: "About"
                font.bold: true
            }

            Label {
                width: aboutDialog.availableWidth
                text: "The Qt Quick Controls 2 module delivers the next generation user interface controls based on Qt Quick."
                wrapMode: Label.Wrap
                font.pixelSize: 12
            }
        }
    }

i want to use ant way for opening dialog in center of page , have any property for this?

The coordinates are relative to the parent. You can set ApplicationWindow.overlay as a parent to use scene coordinates.

Dialog {
    x: (window.width - width) / 2
    y: (window.height - height) / 2
    parent: ApplicationWindow.overlay
}
