I would like to build something similar as attached image.
Drag and drop of images (circle with numbers right side) to a canvas. Between de images there should be a connection (red line) be made (manual/automatic). Example 1-2
Also it should also be possible to add a third image etc. to the end or middle of a existing connection. The connection must be automatically altered.
Can a TPaintbox be used for this functionality and are there similar examples how to start?
Thanks in advance.
