Hi,
I have an editpart representing a component and a child editpart
representing
the ports of this component. I implemented a function performing a rotation
of
the figure including its children which is working perfectly. But when I now
move
the editpart, the location of the editpart and its childeditparts gets
updated correctly,
but the ports (childeditparts) are drawn at a totally wrong position,
although their
location values are correct. If I now for example try to resize the figure
(resize functionality
is not implemented) the figure including its children gets updated and the
ports are
now at the correct position.
I think there is obviously some kind of refresh problem.
Does anybody have an idea.
Thanks
Sebastian.

Another possibility is that you don't get the right bounds in the
refreshVisuals() method of your child editpart. I use this piece of code
at the beginning of each refreshVisuals() :
// notify parent container of changed position & location
// if this line is removed, the XYLayoutManager used by the parent
container
// (the Figure of the ParentEditPart), will not know the bounds of this
figure
// and will not draw it correctly.
Rectangle bounds = new Rectangle(getCastedModel().getLocation(),
getCastedModel().getSize());
where getCastedModel is just a convenient method that returns the model
casted in its right class.
Hope this helps.

Hi,
Thanx for this advise.
I already debug the location coordinates when doing a refresh
and these values are correct, but for some reason the drawing
is just not happening.

I had a similar problem. The symptom is that the edit part moved but not
the connections or the child editparts. I found out that this is becuase I
did the redrawing code in refreshVisual() rather than createFigure(). Once
i fix it, it is OK. Not sure whether this will help you.
Thanks,
Cinly

Ok, i found the solution by myself.
The editpart containing the childeditparts needs to have
a LayoutManager with a XYLayout in its contructor.
Then, everything is working desired.
