I am trying to make an application which will allow to visualise the different steps that make an Relational Algebra query. My application has a drawing panel which holds different smaller JPanels. These
JPanels represent various items - such as tables which act as input to relational algebra operators, or results produced by the relational algebra operators.
Now my issue is I am trying to find a way of connecting these tables in such a way that if i remove a panel to a new location on the drawing panel, the connectors will re-adjust themselves.
I have tried using the Graphics line option to draw these lines, but then when i move a panel these lines dont get adjusted. It will be of great help if someone can give me an idea on how to tackle this issue.
