Hi,

From the error on the IDE console, you should have a QApplication and not a QGuiApplication.

@SGaist i'm having QML application and backend is QT (Qt 5.15) , in my application i'm using chartview
with QApplication its working fine But need to ask is there any problem we might face in project or application if use QApplication instead of QGuiApplication for Qt 5.15 ,

QGuiApplication - base class + GUI capabilities. Use it in QML applications.
QApplication - base class + GUI + support for widgets. Use it in QtWidgets applications.

@KRHC hi and welcome to devnet,

You need QApplication if you use anything that relies on the widgets module. Otherwise, there's no need for it and you would just bloat your deployment for no good reason.
