The QML docs state: > Property bindings are the most common use of JavaScript in QML. > Property bindings associate the result of a JavaScript expression > with a property of an object.
...found at: <http://doc.qt.nokia.com/4.7/qdeclarativescope.html> IMHO, this is one of the most pivotal concepts in QML. However, I'm trying to figure out how to *set* such a binding *within* javascript. Can this be done? For example, when an Item is re-parented, I want to bind a property from the new parent to a property in that child that is being re-parented: Item { id: myParent property int myParentProperty: 42 //... onChildrenChanged: { for(var i = 0; i < myParent.children.length; ++i) { // THIS WILL SET, BUT NOT BIND, THE PROPERTIES. myParent.children[i].myChildProperty = myParentProperty } } I'm interested in "binding" the parent property to the child property because the parent property value actually changes through an animation, and I want the child property to stay "in sync". (I suppose a work-around would be to dynamically create an animation for the child when the child is re-parented, where that animation has properties bound to properties in the parent --?) As I read the docs, the binding occurs *from the results* of javascript across the ":" into QML, not within javascript. Of course, inside the "onChildrenChanged", we only *have* javascript. Is there some kind of API for this? GOAL: Establish binding from parent property to child property when a child is re-parented (I assume this is best performed inside "onChildrenChanged()") Thanks! --charley _______________________________________________ Qt-qml mailing list Qt-qml@trolltech.com http://lists.trolltech.com/mailman/listinfo/qt-qml
