从QML打开Qt窗口

Question

I have created a C++ Qt class, inheriting from QWidget. I have also created a QML file, which runs as my main, and I want in some point of the program to open another separated window containing this widget.

The point is to draw line graphs in QML, and I don't quite understand how to do it.

Answer 1

First of all, take a look at this question and its answers: Qt5. Embed QWidget object in QML

You got into XY-problem . You do not need to embed QWidget to your QtQuick/QML application. (I hope) You can easily deal with your task using only QML. For example, there is Canvas Element that can help you to organize drawing. Take a look at tutorial related to Canvas in QmlBook .

Hope this helps!
