different behavior of AlignmentAction [message #8046]

Hi,

Right now the reference rectangle for the operation is the union
rectangle of the selected editparts. I would prefer that the reference
rectangle are the bounds of the editpart which has the primary selection
status.
Is there any possibility that this could be changed or that
AlignmentAction is no longer declared final and hence
"calculateAlignmentRectangle()" can be overridden?

I've seen applications that do both. The only difference being that a
program like Visio defines primary selection as the first thing you select.
But Windows controls display focus on the *last* item you select. We
decided to make the last item the primary selection. It also looks much
better when using the keyboard (try SHIFT+ARROW_KEY to see focus combined
with primary selection, otherwise you'd have the first item with primary
selection, but the last with a focus rectangle).

So you would be in favor of having the item selected last serve as the
reference rectangle?

I think one motivation of a framework is to provide consistency. Let's
discuss whether the current implementation should be changed first.

Yes, and with shift-click I can make it the last selected item as it
works right now.

At least for me it is much more predictible how the items will move
especially for the middle and center action.

Yes, sure.

The behavior has been changed. The primary motivation for changing this was
that align center and middle were not predictable.
