I am making a diagram editor (with a grid), and I’d like to set some shapes on a grid, that couldn’t be moved, having a fixed position relativily to the diagram zone, not the grid.
What I want to do is place some predefined shapes on the left side of the grid, to be able to drag them with CTRL+move. And when moving across the grid and other objects, I want these objects to stay settled there. I just want to avoid creating two diagrams.
If you have any other idea to implement a drag’n’drop quickly it would be a pleasure.
Thanks for your help :)
