The FlowLayout LayoutManager provides the means to lay out components in a row by row fashion. As each row fills up, the components continue on the next row.
public class java.awt.FlowLayout
extends java.lang.Object
implements java.awt.LayoutManager, java.io.Serializable {
// Constants
public static final int CENTER;
public static final int LEFT;
public static final int RIGHT;
// Constructors
public FlowLayout();
public FlowLayout (int alignment);
public FlowLayout (int alignment, int hgap, int vgap);
// Instance Methods
public void addLayoutComponent (String name, Component component);
public int getAlignment(); 
public int getHgap();
public int getVgap();
public void layoutContainer (Container target);
public Dimension minimumLayoutSize (Container target);
public Dimension preferredLayoutSize (Container target);
public void removeLayoutComponent (Component component);
public void setAlignment (int align);
public void setHgap (int hgap);
public void setVgap (int vgap);
public String toString();
}
The default alignment for a FlowLayout object; rows of components are centered within the container.
An alignment for a FlowLayout object; rows of components start on the left side of the container.
