What is a property alias?
=========================
.. code-block:: js
import QtQuick 1.1
Rectangle {
property alias buttonLabel: label.text
Text {
id: label
text: "empty label"
anchors.fill: parent
}
Unlike a property definition, which allocates a new, unique storage space for the property, a property alias connects the newly declared property, called the aliasing property as a direct reference to an existing property, the aliased property. Read or write operations on the aliasing property results in a read or write operations on the aliased property, respectively.
Further reading can be found in the :qt:`Property Binding<propertybinding.html#property-aliases>` documentation.
