Problems with a layout: not resize the Top Nodes [message #515293]

Hello everybody!

I have implemented a new LayoutEditPartProvider to resize and relocate all the nodes places in my diagram in order to remove the scrolls in the compartments and maximize the space in the diagram to see all the elements correctly.

It works well, but doesn't resize the Top Node elements. All the other elements are correctly resized and relocated, but the Top Node elements only are relocated correctly, not resized. And I don't know why, because the SetBoundsCommand that I have done changes booth the location and the size... But when finishes the layout, this sizes are not changed.

Anybody knows what's happening?

If you allow me, I take the opportunity to propose if you want to add this provider to GMF diagrams by default, because I think it's very useful.

Thanks a lot.
Marc

Hi!

Well, now I know why the Top Nodes are not resized. It's due to the Snap Command added at the end of the ArrangeCommand (the set of commands added by my layout). This Snap Command, takes the Size from the Figure of the EditPart, not from the Node, and it leaves the EditPart in its origin size.

Removing this Snap Command is enough, but I will try to find a possible solution...

Thanks everybody!
Marc

Hi Marc,

Great idea ! I was planning to implement a layout with this behaviour, because I thought it would be usefull indeed. I'd like to see it customizable in GMF.

Anyway, may I ask to get a look on your code ? I would like, if you agree, to use it for my diagram.

Thanks, and good job.
Olivier.

Hello Olivier,

I have added a new feature to GMF (in the bugzilla) in case they want to add to the GMF diagrams by default. Here you can see this feature request, and you can download the code if you want.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=303293

If you use it and founds some enhancements, please contact me Smile

Thanks!!
Marc

Hi,

I get your code and i try to apply it to an activity diagram.

But when running it i don't get the action in the diagram contextual menu.

Can you post an image to show this action?

Thanks in advance,
