Hello i have a question on customizing behaviour of the "Arrange All" function.
Normally all the nodes in are arranged "Bottom-up" as shown in the picture i appended.

Can i change this to a "Top-Down" Orientation quickly , without writing new layouts etc. ?

I think this is a typical use-case so it would be great if it can be fixed quickly.

Greetings

Hello,

I don't know exactly how to do this, but you can have a look to method
org.eclipse.gmf.runtime.diagram.ui.providers.internal.DefaultProvider.layoutTopDown(ConnectionEditPart)
that handles this functionality.

Regards,

Laurent

This is what this function did :

protected boolean layoutTopDown(ConnectionEditPart poly) {
return false;
}

So i think you are wrong.

Currently trying to achieve the same. It would really help if you could let us know how you did it. Smile

Found it!

Add the following extension to plugin.xml (of the generated GMF diagram project).

<extension point="org.eclipse.gmf.runtime.diagram.ui.layoutProviders">
<?gmfgen generated="false"?>
 <layoutProvider class="org.eclipse.gmf.runtime.diagram.ui.providers.TopDownProvider">
  <Priority name="High"></Priority>
 </layoutProvider>
</extension>
