How to add image after and before the text of ColumnLabelProvider

Question

I have tried by extending ColumnLabelProvider and used below code to the checkbox tree viewer

getTree().addListener(SWT.PaintItem, new Listener() {
            @Override
            public void handleEvent(Event event) {
                TreeItem treeItem = (TreeItem) event.item;
                ConfigTreeViewNode item = (ConfigTreeViewNode) treeItem.getData();
                if (!(item instanceof ConfigTreeViewNodeConfig)) {
                    return;
                }
                ConfigTreeViewNodeConfig configNode = (ConfigTreeViewNodeConfig) item;
                if (configNode.getValidationMessage() == null) {
                    return; // not evaluated yet
                }

                ConfigTreeViewLabelProvider labelProvider = (ConfigTreeViewLabelProvider) getLabelProvider();
                Image image = labelProvider.getConversionValidationStateImage(configNode.getValidationMessage());
                int x = event.x + event.width + 2; // give small margin
                int itemHeight = getTree().getItemHeight();
                int imageHeight = image.getBounds().height;
                int y = event.y + (itemHeight - imageHeight) / 2;
                event.gc.drawImage(image, x, y);

            }
        });

after this I am able to see ImageICON LabelText ImageICON as shown below

But when I mouse over on the node only first image and text are highlighted and tool tip is coming for them. I want to highlight the third image also and want to bring the tool tip like other selection.
