Examples of com.vaadin.ui.Component.addStyleName()

com.vaadin.ui.Component.addStyleName()
Adds a style name to component. The style name will be rendered as a HTML class name, which can be used in a CSS definition.
```
 Label label = new Label("This text has style"); label.addStyleName("mystyle"); 
```
Each style name will occur in two versions: one as specified and one that is prefixed wil the style name of the component. For example, if you have a {@code Button} component and give it "{@code mystyle}" style, the component will have both " {@code mystyle}" and " {@code v-button-mystyle}" styles. You could then style the component either with:
```
 .mystyle {font-style: italic;} 
```
or
```
 .v-button-mystyle {font-style: italic;} 
```
This method will trigger a {@link com.vaadin.terminal.Paintable.RepaintRequestEvent RepaintRequestEvent}.
