2D editable grid
-
Hello,
I'm a new Qt user, and I'm trying to code a small application for educational purposes.
It's a graphic application, the user load an image in a scene, and on top of that image I want to set a layer which contains a 2D grid.
The 2D grid is editable, let me explain: each point located at the intersection of two lines of the grid can be moved.
And here comes my questions:- How is it even possible to simulate the layer concept just like applications like Gimp or Photoshop do ?
- And finally, I heard about QGraphicsItem, is it a good idea for a 2D editable grid ?
Thank you for reading (my apologies if there are some english mistakes).

Yes that is doable using the Graphics View Framework.
this example might be of interest, other examples can be found here. -
Thank you, that's nearly the thing I had in mind, I've missed that example when I was reading the documentation.
I'll read that carefully !Have a good day !
