Bug 34335 DND doesn't work
RC2 Linux-GTK Drag and drop doesn't work. I've tried it in the DNDExample and in the package explorer and drags are never initiated.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/browsing/JavaBrowsingPart.java
return fHasWorkingSetFilter;
	}
	protected void setOpenEditorGroup(OpenEditorActionGroup fOpenEditorGroup) {
		this.fOpenEditorGroup= fOpenEditorGroup;
	}
	protected OpenEditorActionGroup getOpenEditorGroup() {
		return fOpenEditorGroup;
	}
	protected BuildActionGroup getBuildActionGroup() {
		return fBuildActionGroup;
	}
	protected CCPActionGroup getCCPActionGroup() {
		return fCCPActionGroup;
	}
	
	private boolean linkBrowsingViewSelectionToEditor() {
		return isLinkingEnabled();
	}
	public void setLinkingEnabled(boolean enabled) {
		fLinkingEnabled= enabled;
		PreferenceConstants.getPreferenceStore().setValue(getLinkToEditorKey(), enabled);
		if (enabled) {
			IEditorPart editor = getSite().getPage().getActiveEditor();
			if (editor != null) {
				setSelectionFromEditor(editor);
			}
		}
	}
}
