Bug 79419 [Preferences] Need a link component
We need to create a some sort of component for preference pages to use for linking. We should look into pushing down the org.eclipse.ui.views.framelist mechanism possibly.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/AbstractConfigurationBlock.java
iter= fMasterSlaveListeners.iterator();
        while (iter.hasNext()) {
            SelectionListener listener= (SelectionListener)iter.next();
            listener.widgetSelected(null);
        }
     
        updateStatus(new StatusInfo());
	}
	public void performOk() {
	}
	public void performDefaults() {
		initializeFields();
	}
	IStatus getStatus() {
		if (fStatus == null)
			fStatus= new StatusInfo();
		return fStatus;
	}
	/*
	 * @see org.eclipse.jdt.internal.ui.preferences.IPreferenceConfigurationBlock#dispose()
	 * @since 3.0
	 */
	public void dispose() {
	}
	
	private void numberFieldChanged(Text textControl) {
		String number= textControl.getText();
		IStatus status= validatePositiveNumber(number);
		if (!status.matches(IStatus.ERROR))
			fStore.setValue((String) fTextFields.get(textControl), number);
