Conceptually something like,
// main.qml
Item {
    ....
    Dialog { // make Dialog a direct child of the main window
        anchors.fill: parent; // Dialog spans the entire window
        MouseArea { anchors.fill: parent; onClicked: opacity = 0; } //
handle outside clicks
        Rectangle { // the dialogs content
            anchors.centerIn: parent
            MouseArea { anchors.fill: parent; } // absorb clicks in
the "content" area so that it won't close the dialog
            ...your dialog's widgets...
        }
    }
}

You can expand on the above idea to use a Loader so that the Dialog
gets created lazily.
