Hi there,
The purpose of the ImageRegistry in the plugin is to maintain a list of
ImageDescriptors. The documentation implies that it takes care of
"creating, managing and disposing these images directly".
However, as near as I can tell, you still have to create the Images
manually from these descriptors.
And do you actually have to manually dispose of each image you create as
well? For example, if I call
Item.setImage(imageDescriptor.createImage()) - I have to dispose of that
image - and I can't do it by overriding dispose(), I have to set up a
listener in my Item object to listen for the DISPOSE event?
Is that correct, or does JFace indeed take care of a lot of this for me?
Thanks,
Andy

If you use ImageRegistry.get(String), it will create and manage the
image for you. Generally, there is no easy solution for image sharing.
In many cases you will have to take care of disposing the image
yourself. See the Image article on eclipse.org for more details:
