    Hello, Newbie question here,
    I have a Qlabel which I set my Pixmap in a video form. Those who know my project, I have timers to get every frame.

    Now I want to get the RGB pixel data and show it on the status bar when I hover my mouse over an image.

    I have looked through the documentation but I am not sure how to implement it? any youtube video or reference examples will be great.

    https://doc.qt.io/qt-5/qimage.html#pixel

    In addition I want to get the X and Y positions to show on the status bar too

      Enable mouseTracking() on the QLabel and overwrite QWidget::mouseMoveEvent() to get the current mouse position.
