I'm trialling uniGUI with a view of creating and displaying flow diagrams. In this screenshot I want to be able to create directional links (lines with arrow heads) between the panels, with the links moving and stretching as the user moves the panels about. This a common UI that many of us are familiar with. What is the best way to achieve this with uniGUI? Would I need a TuniCanvas dynamically sized and positioned between each pair of panels and some logic to draw an arrow on it? Don't know where to start with this. Thanks, Paul
