For example, you could bind the text of a label to the value of a slider: as the value of the slider changed, the label would be automatically updated with the new value. -Bindings are created in QML when an expression is assigned to a property.

For example, the following produces two rectangles of equal size (\c rect2 is bound to the size of \c rect1): \code -Rectangle { id: Rect1; width: 100; height: 100 } -Rectangle { id: Rect2; width: Rect1.width; height: Rect1.height } +Rectangle { id: rect1; width: 100; height: 100 } +Rectangle { id: rect2; width: rect1.width; height: rect1.height } \endcode There is also a special \l Binding element, which is typically used to bind from the UI to the underlying UI model (see \l {Passing Data Between C++ and QML} for an example of this). The bindings above could be expressed using the \l Binding element as: \code -Binding { target: Rect2; property: "width"; value: Rect1.width } -Binding { target: Rect2; property: "height"; value: Rect1.height } +Binding { target: rect2; property: "width"; value: rect1.width } +Binding { target: rect2; property: "height"; value: rect1.height } \endcode In addition to binding directly to a property, you can also bind to the results of expressions involving properties.
