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 } -\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 } -\endcode - -In addition to binding directly to a property, you can also bind to the results of expressions involving properties. For example: -\code -Text { text: contact.firstname + ' ' + contact.lastname } -Image { source: if (contact.gender == "female") {"pics/female.png"} else {"pics/male.png"} } -\endcode - -Relevant items can also be bound to the contents of a model - see \l ListView for an example of this. - -Data can be bound to C++ objects - see \l {QML/C++ Data Binding}. -*/ - -/*! \page qtbinding.html \target qtbinding \title QML/C++ Data Binding |
