```
public class MagicLayout
extends ComponentContainer
```
Represents a layout in which component positions and sizes can be adaptively adjusted.
Components in a MagicLayout have seven adaptive features, including wrapping, stretching, scaling, extension, proportion, equalization, and hiding.
- Wrapping feature: A component in a MagicLayout will be put to the next line when there is not enough space in the current line. The wrapping feature will not work if components are arranged vertically in the layout.
- Stretching feature: Components in a MagicLayout can be stretched horizontally or vertically to adapt to the layout.
- Scaling feature: Components in a MagicLayout can be scaled to adapt to the layout.
- Extension feature: The number of the components that can be displayed in a MagicLayout varies depending on the container.
- Proportion feature: Specified components in a MagicLayout are always arranged based on a proportion.
- Equalization feature: Components in a MagicLayout can adapt to the size change of the layout with the same space between adjacent components.
- Hiding feature: Components in a MagicLayout are displayed in the horizontal or vertical direction with defined priorities. A component with a lower priority may be hidden if the current layout does not have sufficient available space.
