|
---|
31 |
|
---|
32 | Property binding is a declarative way of specifying the value of a property. Binding allows
|
---|
33 | a property's value to be expressed as an JavaScript expression that defines the value relative
|
---|
34 | to other property values or data accessible in the application. The property value is
|
---|
35 | automatically kept up to date if the other properties or data values change.
|
---|
36 |
|
---|
37 | Property bindings are created implicitly in QML whenever a property is assigned an JavaScript
|
---|
38 | expression. The following QML uses two property bindings to connect the size of the rectangle
|
---|
39 | to that of \c otherItem.
|
---|
40 |
|
---|
41 | \code
|
---|
42 | Rectangle {
|
---|
43 | width: otherItem.width
|
---|
44 | height: otherItem.height
|
---|
45 | }
