when i create elements in root diagram - ok (use the same
CreateNodeCommand)

when i put new element (from palette tools) in my container - this element
appear in container with some offset. When i look in my
CreateNodeCommand.SetLocation - location value is right, but when this
command .Execute() - location value is wrong. Where this value can changed?

I encountered the same problem as you did. I used XYLayout for the container.

Does anyone have any idea? Thanks.

I tried to track/change the coordinating system of the direct container and the top-most container of a graphical node, but I still cannot get out of an offset.

Any idea will be appreciated!

are you use "subdiagram"?

now i look to this process behavior and what i see.. new element laying on
subdiagram with coordinates from root-diagram
(for example - if you put container to diagram in 100,0 coordinates then
ofsset children will be only horizontal, and if you put child in top-left
container's corner - then child coordinate will be ~100,0)
lets find solution

so.. in XYLayoutEditPolicyImpl.getCreateCommand (and other commands if
required)

IFigure pane = ((AbstractGraphicalEditPart)getHost()).getContentPane();
Point p = request.getLocation();
pane.translateToRelative(p);

and command.setLocation(p);

it's work to me

Thanks Alexey,

I've just found the solution by myself by adding the following two lines to the execute() method:


child.setX(request.getLocation().x - parent.getX());
child.setY(request.getLocation().y - parent.getY());

It works.

But I find that your solution is better, so I'll use it. Thanks again.

Bests,
