Class SinLayout

java.lang.Object
  fr.upd.jby.SinLayout

All Implemented Interfaces:

LayoutManager

public class SinLayout
extends Object
implements LayoutManager

Using this layout in a real application is a sin. It has been designed to demonstrate how to implement a LayoutManager. It lays components one below the other, starting from the top of the container space, and such that, left and right margins draw a sinusoid. Source code here and a sample here.

Constructor Summary

SinLayout()
Constructs a default SinLayout which glues component's borders to the respective left and right borders of their container.

SinLayout(int cpc, int zenith)
Constructs a SinLayout which glues component's borders to the respective left and right sinusoidal border of their container, with strict respect to their minimum size.

Method Summary

void	addLayoutComponent(String n, Component c) Adds the specified component to the layout.
void	layoutContainer(Container c) Lays out the container.
Dimension	minimumLayoutSize(Container c) Returns the minimum dimensions needed to layout the visible components contained in the specified target container.
Dimension	preferredLayoutSize(Container c) Returns the preferred dimensions for this layout given the visible components in the specified target container.
void	removeLayoutComponent(Component c) Removes the specified component from the layout.

SinLayout

public SinLayout(int cpc,
                 int zenith)

Constructs a SinLayout which glues component's borders to the respective left and right sinusoidal border of their container, with strict respect to their minimum size.

Parameters:

cpc - the number of component per period of the sinusoid.

zenith - the zenith of the sinusoid, in pixels.

Method Detail

addLayoutComponent

public void addLayoutComponent(String n,
                               Component c)

Adds the specified component to the layout. Not used by this class.

Specified by:

addLayoutComponent in interface LayoutManager
