hello everybody,

i want to make a circle which i can make if i provide the same height and width to the ellipse. but if i will resize it, the circle will be deformed.

so how can i disable the central resizing points leaving only the corner resizing points, or if possible how can i use the resizing option in custom style?..,

i just want that when i resize my edit part the width and height of the edit part remains same so that the structure of the circle is not distorted,

so if any one knows that where this part is handled (the method which handles the resizing) in gef then please do tell me, so that i can try changing it..,

Hello Sharad,
On resizing, you need to make sure that your model gets
updated properly. You need to look at the command you have written to
update the circle model.

Well, GEF is not supposed to know anything about the your model. This
enables us to come up with an editor based on our 'Domain Specific model'.
All the information about the objects (circle in your case), is persisted
in the model.
Since you are trying to resize your objects, you need to investigate the
Layout policy installed on your EditPart.

You may like to have a look at these links-
http://wiki.eclipse.org/GEF_Description
http://www.eclipse.org/articles/Article-GEF-diagram-editor/s hape.
This will help you to get a better understanding of the framework.
