using ChartView crashes app

mzimmers

Hi all -

I've been developing a view using a ChartView in qmlscene for a bit, and just tried using it within my app. I get a segfault:

Here's the extract of the qml file:

import QtQuick 2.12
import QtQuick.Controls 2.12
import QtQuick.Layouts 1.14
import QtCharts 2.3
import libstyles 1.0


Rectangle {
  id: root
    ChartView {
    }
}

Any ideas what's going on here? I don't see anything in the docs about having to set a theme, but the stack trace seems to imply that it expects one.

Make you app QApplication instead of QCoreApplication.

@fcarney I definitely am going to owe you a beer (or three)...that fixed it. (It was originally a QGuiApplication, but changing it fixed things.)

So, in a nutshell...what was wrong?

QtCharts uses widgets under the hood.
