A Panel container consists of a title bar, a caption, a border, and a content area for its children. Typically, you use Panel containers to wrap top-level application modules. For example, you could include a shopping cart in a Panel container.

The Panel container has the following default sizing characteristics:

Characteristic Description
Default size Height is large enough to hold all of its children at the default height of the children, plus any vertical gaps between the children, the top and bottom padding, the top and bottom borders, and the title bar.
Width is the larger of the default width of the widest child plus the left and right padding of the container, or the width of the title text, plus the border.
Padding 4 pixels for the top, bottom, left, and right values.
