Hi everybody,
I am currently trying to resize a QGraphicsRectItem through my QGraphicsScene
using the MouseMoveEvent method.
In the latter, I’m checking if the application is in the “startModifying” mode

You will have to normalize the rectangle c
Hi Michael,
I implemented your method and it works pretty well. Thank you so much for
your help.
This is the code (ImageGraphicsSceneW subclasses ImageGraphicsScene).

In the mousePressEvent you would create a QGraphicsRectItem, add it to the

Hi everybody,
I would like to create a Graphical User Interface which allows the user to

bool Imag
