Hi,

was the old ZEST (1.x) API enhanced for turning off the animation?

I found the topic that mentions this issue and includes the reference to a bug fix in https://www.eclipse.org/forums/index.php/t/79324/.
However, the resolution refers to the new ZEST in GEF4.

Does anyone solved this issue in ZEST 1?

Thanks for your support!
Wladimir

I think the old Zest API never offered an option for animation. The bug you refer to targeted the (intermediate) Zest2 code base, which was discontinued (as GEF4 Zest was rewritten from scratch).

Hi Alexander,

thanks for your reply.

ZEST 1.x (the one form http://download.eclipse.org/tools/gef/updates/releases/) offers animation but no way to turn it off or reduce the animation time.
We are still using it and, and now we need to turn off animation because it unnecessarily consumes 500ms of time.

Does it mean that the ZEST 1.x is not maintained anymore?

I think you are then referring to the animation hint within GraphContainer, right?. The bug you referred to animation support within GraphViewer, which was provided only in the Zest2 code base.

The status of Zest 1.x is "pure maintenance". That is, we will fix problems as long as we can do without breaking API. We do not actively develop it further. Our focus is on its successor, GEF4 Zest.

ok, I see. Thank you for the answer.

Do you think it is feasible remove the final modifier from
public static final int ANIMATION_TIME = 500;
in org.eclipse.zest.core.widgets.Graph?

That would already solve our issue because then we could reduce the animation time to a minimum. This would not break the API, right?

I will take a look at it. Please open a Bugzilla.

I can disable (layout) animations like this:

		GraphViewer viewer = new GraphViewer(parent, SWT.None);
		viewer.setNodeStyle(ZestStyles.NODES_NO_LAYOUT_ANIMATION);


Or do I miss something in this conversation?

Thanks, Erdal! That was what I was looking for.
It was no obvious to me that can be defined for viewer.

@Alexander, thanks, my issue is solved.
