How to stop child movement on parent Editpart Resize(WEST, NORTH)? [message #214056]

Hello,

I have a parent editpart 'A' and inside it A's compartment and inside this
compartment I have a child editpart 'B'. When I resize the 'A' editpart on
NORTH or WEST direction, the child 'B' also moving along with the
direction of resize. For opposite directions SOUTH or EAST, child 'B' is
not moving. How can I stop moving this child 'B' on parent resize?. Is
this because of compartment problem?. Is there any policies available?.

Thanks In Advance,
Nagesh Y.J.

Hello Nagesh,

I think child elements are positioned inside a compartment in a relative
coordinates.
So, to solve this problem you have to use absolute coordinates (modify generated
code manually). BTW, are you using list compartment or non-list one?

Hello Alex,

We are using non-list one. Please provide me information of where to
change the relative to absolute coordinates?.

Thanks In Advance,

You have to:
1. Modify LayoutEditpolicy (XYLayoutEditPolicy) created inside createlayoutEditPolicy()
method of the EditPart representing parent node to use absolute coordinates
in SetBoundsCommand.
2. Modify refreshBounds() method of the EditPart representing parent node
to properly set layout constraints for the child node.

It can happen that instead of parent node EditPart you have to modify compartment
EditPart on both steps - I'm not sure about that since i did not try this
very steps by myself.
