Wicket Tooltip

Do you need to add tooltips to your web application?
Do you use Wicket and want a "behavior" that adds tooltip functionality to any Component?
If you answered yes to both questions the I have the solution! I used code from the article "Create a Nice, Lightweight JavaScript Tooltip" and I generated a behavior like class that uses the javavascript and style sheet in order to add tooltip functionality to any Component. The code of the behavior like class looks like the following:
public class TooltipPlugin implements Serializable{
private final Component component;

public TooltipPlugin(Component component, String tooltip) {
this.component = component;
component.add(HeaderContributor.forJavaScript(getClass(), "TooltipBehavior.Script.js"));
component.add(HeaderContributor.forCss(getClass(), "TooltipBehavior.Style.css"));
setTooltip(tooltip);
}

public void setTooltip(String tooltip) {
if (tooltip == null || tooltip.length() == 0) {
component.add(new AttributeModifier("onmouseover", true, new Model("")));
component.add(new AttributeModifier("onmouseout", true, new Model("")));
} else {
component.add(new AttributeModifier("onmouseover", true, new Model("tooltip.show('" + tooltip + "');")));
component.add(new AttributeModifier("onmouseout", true, new Model("tooltip.hide();")));
}
}
}
Where the "TooltipBehavior.Script.js" and "TooltipBehavior.Style.css" are the script and the style sheet files from the article "Create a Nice, Lightweight JavaScript Tooltip".
