How to interact with a PlatformGraphicsAlgorithm? [message #1714240]

Hi,

So my PlatformGraphicsAlgorithm (PGA) is backed up by a draw2d ScrollPane, so naturally I want to populate it with other Figures.

I'm currently implementing a move feature for the figure I want to move into the PGA/ScrollPane. But when I try referring to the GraphicsAlgorithm of the targetContainer (the PGA/ScrollPane), there seems to be no way to access its contents so I can update them and redraw the figure.

Is there any way to do this? How can I interact with a PGA once it's drawn?

Thanks again,

Raf

I should mention that the targetContainer's GraphicsAlgorithm (PlatformGraphicsAlgorithmImpl) has an 'id' that corresponds to the id defined in my RendererFactory. Is there any way to use that?

Rafal,

the associations between your PGAs and its visualization or children in the visualization is something you need to track yourself. Graphiti only knows about the outer shape and that it has a custom visualization. For our GEF mapping we also need to keep track of the association between shapes/GAs and the accoring edit parts/figures. We don't need to care about children since that is modeled on level of Graphiti objects, though.
