有什么方法可以使用 C++ 类作为 QML 组件，它可以在设计器中拖动和使用吗？

Question

I have a C++ class in which I set the image path which will be available only at run time. I want to use my class as a Custom QML component which should be available in designer tab & I can drag that & use in form editor.

Answer 1

You should separate logic from view.
For an starting point, expose your images paths as model into QML and use a ListView with a Rectangle as delegate and assign model to it. Therefore you have a rectangle for each image path.
