Disallowing moving a part [message #663141]

Hi all,

I would like to know what tag should be added to a part so that we disallow moving of the part? (dragging and dropping the part therby changing the perspective layout)
For disallowing closing it is "NoClose", but I can't seem to know for disallowing moving...

Thank you for your help!

I've just committed the code to support this. The appropriate tag to use to inhibit moving a part is IPresentationEngine.NO_MOVE.

Adding this tag to a part will prevent the DnD's PartDragAgent from starting a drag on the part.

See bug 341793.

Hi,

This is not working Sad

part1.getTags().add("NoClose"); works!
part1.getTags().add("NoMove"); doesn'work!
part1.getTags().add(IPresentationEngine.NO_MOVE); doesn'work!

When I say doesn't work, it means I am still able to drag and drop a part to another place (say I can move it from the partstack it was in to another partstack, etc...)
This is the behavior I would like to disallow...

On the same topic, suppose the user moves around parts and changes perspective, is there a way to reset the perspective when the app starts again the next time?
Note that most of my application model is not programmatically defined, rather defined in the Application.e4xmi

Thank you

Did you checked out the latest sources? As Eric said he just checked in
that change to CVS!

You need '-deltaRestore false' as an argument to your application.

If that's not working, use breakpoints in E4Application to check if it's being parsed correctly.

Hi, thanks for your answers.
Sorry did not notice I should apply Eric's patch :/

But I am quite a newbie so I searched how to apply the bug fix patch but I am not able to know exactly how. Is it using the Team perspective in eclipse platform? But how to apply the patch to the e4 src code (not my project ).

Hello Eric
Thank you for the contribution.

I downlaoed the latest I build (April 5, 2011)
and tried
part.getTags().add(IPresentationEngine.NO_MOVE);

but the tag still moves around..

NoClose works.
