JS::GlobalDeviceEnumerator Class Reference
Inheritance diagram for JS::GlobalDeviceEnumerator:

Detailed Description

QML writes enumerate and the filter in an order the author cannot choose: literals before script bindings, and two literals in reverse source order (qqmlirbuilder.cpp, QmlIR::Object::appendBinding prepends). Enumerating unfiltered is expensive and on Windows deadlocks, so the walk waits for componentComplete(), after finalize() has converged every binding. Only QML object creation defers; Score.enumerateDevices() still walks on the write.
