Hi all. I made an algorithm for resizing a picture(inherited from QGraphicsItem) using vector mathematics (I added points to the corners and using the mouse, the picture is resized while maintaining the aspect ratio https://www.qtcentre.org/threads/715...g-aspect-ratio , gif: https://gph.is/g/Zr0WdxJ).

Next, I created a group(inherited from QGraphicsItemGroup) add border dots(inherited from QGraphicsRectItem) and added pictures to the group (via addToGroup).

Is it possible to generalize this algorithm to a group? So that all pictures in the group are resized with border dot position.

this what I want: https://gph.is/g/EJxpeVQ (PureRef app) and this is what I got: https://gph.is/g/aQnpq5x

here the project if anybody wants to run application: https://github.com/try-hard-factory/...emgroup-resize (borderdot.h/cpp, itemgroup.h/cpp)

can't resize childs... ... Can I use GraphicsItemGroup to implement the function of resizing the child items or will I have to write it by hand because, for example, this class allows you to move all the childs in a group.
