How to create a drag and drop application?

[Matuzo]

Hello everyone, I'm starting to use the tool and I need to make a drag and drop application. Being more specific, I intend to create an application that simulates features of the OpenCV library through custom widgets. Could someone point me to possible ways for me to start?

Did you look through Drag and Drop Examples as a start?

Hi and welcome to devnet,

Beside the good pointer of @JonB, why simulate OpenCV ? You can use it with Qt.

@JonB
Thanks for answering. I didn't know the drag and drop tutorials and now I'm going to study them.

Maybe I expressed myself badly. I meant that I'm going to use opencv to create a graphical application that uses its functions in interconnected block diagrams.
