Can my Eclipse plugin change preferences from other plugins?

I'm working on an Eclipse plugin that needs to change so开发者_StackOverflow中文版me preferences defined by other plugins, e.g. the tab size in text editors. Is that possible?

Yes, it is possible.

You'll need this in your preference page:

setPreferenceStore( new ScopedPreferenceStore( new InstanceScope(), "bundle-name-of-other-plugin" ) );

Or you could do something like this here.

FYI, the preferences live here:

pathToWorkspace\.metadata\.plugins\org.eclipse.core.runtime\.settings
