Drawing a rectangle selection box on QImage using Mouse?



  • I want to draw a rectangle on a QImage that is displayed on a QLabel using Mouse.
    I am using Mouse events as SIGNALS in a separate class of my_qlabel.
    But then i don't know how to get these mouse event work for drawing a selection box on the image. And after drawing the selection box i want the image to be cropped to the size of the rectangle.
    Need help.
