Scrollbars ignore connections and their labels [message #245615]

I have a GEF editor where some connections and their labels extend to the
left into an area with no other figure. The problem is that I can only
scroll to where the last normal figure ends, which cuts off the connections
and their labels. It seems like the scrollbar ignores the connection layer.
What can I do to make the scrollbar take the connection and their labels
into account?

Thanks, Felix

Hi,

Perhaps you add your layers to the root figure as children... Root figure
should really have one child - the contents figure. This contents figure
should have your primary, connection, feedback and etc. layers as its
children.
To answer this correctly I need to know your figure hierarchy and whether
you override anything in ScrollingGraphicalViewer and/or RootEditPart.
Hope this helps.

Cheers,
Alex

Hello Alex,

I don't do anything fancy with the layers or the classes you mention. I use
basically the defaults and set a ScalableRootEditPart on the GraphicalViewer
of my editor. On the Viewport I set viewport.setContentsTracksHeight(true),
but that's about it apart from a KeyHandler and a context menu. The only
special thing is that some connections are routed first away from a node and
then come back to it. That's why I am so surprised about this behavior.

Thanks, Felix
