labelControl.setText(label);

		gd.horizontalIndent= indentation;
		labelControl.setLayoutData(gd);

		Button button= editor.getButton();
		button.setData(editor);
		
		gd= new GridData();
		gd.horizontalAlignment= GridData.END;
		button.setLayoutData(gd);
		button.addSelectionListener(fColorButtonListener);
		
		fColorButtons.put(editor, key);
