GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.add the gwt links DiagramControllerto a tab panel and with a scrollbar

Entrypoint
    TabPanel
       ScrollPanel
           VerticalPanel
                Horizontal panel with buttons ( toolbar )
                DiagramController

The graph will render with the connections mis-aligned ( apparently relative to 
the Scroll panel and not the vertical panel

A graph will render properly WITHOUT the scroll panel however with the scroll 
panel the connections are not draw properly.

See attached example screenshot

What version of the product are you using? On what operating system?
Using gwt-links 1.3 and this is evident in all versions of Firefox and IE

Hi - I tested again using the latest build and the problem is still evident.

It appears the connections are being drawn with a vertical offset that somehow 
has added the parent offset within the scrollpanel. The attachment shows the 
lines being 'shifted' - they are in fact being drawn as segments between 2 
points that have been shifted to compensate for the offset of the view within 
the parent panel.

Also - please note the scroll panel is outside the diagram. It is not the 
scroller that is built into the DiagramController and instead scrolls around 
the DiagramController and the other UI elements ( buttons etc )
