c++ and qml binding

[ganeshgladish]

hi,
how to receive signal from c++ to qml....using qdeclarativeview i am able to bind qml with c++ but i don't know how to bind c++ with qml....

Expose a C++ object to QML engine using QDeclarativeContext::setContextProperty() and use one of the means available (either the Connections element or javascript object.signal.connect(slot) expression) to connect a QML function to such object's signal.

You might want to consider exposing the data as a model.
Maybe you can even use QSqlQueryModel?
