Description

This article has many functionality. Dynamic Widget, Widget Reflection, Video Playback are the main attraction. Along with that I have used OpenGL in this application. Below are some code sample and the complete project is wrap up into the zip file. In the GUI there is a QGraphicsView widget. I promoted it to imageViewer2d. In mainWindow.cpp you can see how it works for images and background. You can also give a try to do something when scroll right limit it reached.

Prerequisite

Take a video and image file and copy to the project folder. Set the video and image file path in the mainWindow.cpp.
