FAQ How do I use images defined by other plug-ins?
In general, you should not rely on images defined in other plug-ins as they could be changed or removed at any time. The exception to this rule is an image that has been declared by a plug-in as an API. The convention is to create an interface called ISharedImages that defines IDs for all images that you want to declare as API. Several plug-ins, including org.eclipse.ui.workbench, org.eclipse.jdt.ui, and org.eclipse.team.ui, declare such an ISharedImages class. Here is an example snippet that options the folder icon from the workbenchs shared image API:
IWorkbench workbench = PlatformUI.getWorkbench(); ISharedImages images = workbench.getSharedImages(); Image image = images.getImage(ISharedImages.IMG_OBJ_FOLDER);
If you want to share images from your plug-in as API, you should define your own ISharedImages class with constants for all the images you want to make public.
