Class FitLayout

java.lang.Object

org.jitsi.util.swing.FitLayout

All Implemented Interfaces:

LayoutManager

Direct Known Subclasses:

VideoLayout

public class FitLayout
extends Object
implements LayoutManager

Represents a LayoutManager which centers the first Component within its Container and, if the preferred size of the Component is larger than the size of the Container, scales the former within the bounds of the latter while preserving the aspect ratio. FitLayout is appropriate for Containers which display a single image or video Component in its entirety for which preserving the aspect ratio is important.

Method Summary

Modifier and Type	Method	Description
void	addLayoutComponent(String name, Component comp)	Does nothing because this LayoutManager lays out only the first Component of the parent Container and thus doesn't need any String associations.
protected Component	getComponent(Container parent)	Gets the first Component of a specific Container if there is such a Component.
protected void	layoutComponent(Component component, Rectangle bounds, float alignmentX, float alignmentY)
void	layoutContainer(Container parent)
protected void	layoutContainer(Container parent, float componentAlignmentX)
Dimension	minimumLayoutSize(Container parent)
Dimension	preferredLayoutSize(Container parent)	Since this LayoutManager lays out only the first Component of the specified parent Container, the preferred size of the Container is the preferred size of the mentioned Component.
void	removeLayoutComponent(Component comp)	Does nothing because this LayoutManager lays out only the first Component of the parent Container and thus doesn't need any String associations.
