I have an application, in which i am passing model from c++ to QML. Now i want to debug QML file. SO how can i debug QML from C++ files step by Step. Please suggest me for this.
QtCreator provides a lot of built-in QML debugging helpers. I suggest you use QtCreator for debugging QML applications.
If you want to manually debug and monitor sections of code, you can use the console API provided - see http://doc-snapshot.qt-project.org/5.0/qtquick/qtquick-debugging.html for more information.
