What is the Best place to dispose Images [message #167530]

Hi,
If i have a figure which internaly instantiates
org.eclipse.swt.graphics.Image
Where is the best place to call .dispose() on image

My solution was:

Editpart.deactivate()->MyFigure.destroy().->image.dispose()
Method destroy is my own not any inherted.

I'm interested in standartized solution.
Thanks,
Karel

You could always keep the image in the edit part and dispose it when it
is deactivated. In this solution the figure just holds a reference to
the image, but does not own the image. So you have

EditPart.refreshVisuals -> MyFigure.setImage
EditPart.deactivate -> image.dipose

You probably have multiple instances of that figure, so the figure is not
the best place to manage a resource. But what you have should work.
