30\title Property Binding
31
32Property binding is a declarative way of specifying the value of a property. Binding allows
33a property's value to be expressed as an JavaScript expression that defines the value relative
34to other property values or data accessible in the application. The property value is
35automatically kept up to date if the other properties or data values change.
36
37Property bindings are created implicitly in QML whenever a property is assigned an JavaScript
38expression. The following QML uses two property bindings to connect the size of the rectangle
39to that of \c otherItem.

41\code
42Rectangle {
43 width: otherItem.width
44 height: otherItem.height
