How do I resize an element and the element inside it? [message #209872] Mon, 20 February 2006 18:24 Go to next message

If I define a LAYOUT_ROLE to something like XYLayoutPolicy, then I can
resize the children, but not the parent. IF its a ResizableEditPolicy,
the parent can be resized, but not the childres.

Should I implement a new policy? If so, any tips how? I want that
whenever the parent resizes, so does the children. But the opposite is
not always true.

thanks

You need to be using the XYLayoutPolicy on the *parents* of anything that
you want to resize. ResizableEditPolicy is not a LAYOUT_ROLE. It is
PRIMARY_DRAG_ROLE.

boa sorte.

But If I use ResizableEditPolicy as a PRIMARY_DRAG_ROLE, I loose the
selection handles in my element, together with the ability to move/resize.

installEditPolicy(EditPolicy.PRIMARY_DRAG_ROLE, new
ResizableEditPolicy());
installEditPolicy(EditPolicy.LAYOUT_ROLE, new
DiagramLayoutEditPolicy()); /extends XYEditPolicy

Is there something different I should be doing?

thanks

Later I will try to make everything else to worl

Now resizing/moving works fine, but I can't see the feedback (the gray
rectangle)! I'm using a XYLayoutEditPolicy. Should I ovewrite something?

thanks

It sounds like you might have two of the same policies installed. resize
feedback is XOR, so if it paints twice, it will erase itself.

ResizableEditPolicy should be created inside the LayoutEditPolicy in
createChildEditPolicy(...). You shouldn't install it from the editpart.
