Drag and drop onto a predetermined grid.

My current project is to design a GUI that allows users to create a series piping system with pumps, valves, connectors, and other things. What I would like to do is have all the possible parts shown on the side and then have the user drag them onto a grid where they would snap into place. Is there something in MATLAB that would allow me to do this or would I have to track where the piece is and manually tell it what position to snap to?

I do not know a method, which does this automatically. But snapping is easy, because you only have to find the nearest matching location.

How would one go about making the grid for the images to be dropped on?
