|
| public |
addClass(cls) Add a CSS class name to the class list of the HTML element associated with the box. |

border(b) Get or set the border definition of the box. |
| public | int |
bottom(b) Get or set the bottom of the box. |

|
| public | int |
Get the client height of the box. The client height is the height of the box minus the top and bottom border and padding width. |

So the job of the overridden layOut method is to recalculate the size and position of all the child elements of the box when the layout manager sets the size of the box and calls the box's layOut method. |
