Vertical layout Problem!

Question

I have implemented a Vertical layout Which ads the componenst vertically.
The problem is the components gets added below the last component added.I want to add the component at the specific location ie : Point in the container...Can somebody please help me out !!!
the code for Vertical layout is
public class VerticalLayout implements LayoutManager2,Serializable{
private int MIN_WIDTH=300;
public float getLayoutAlignmentY(Container target) {
return 0.0f;
public float getLayoutAlignmentX(Container target) {
return 0.0f;
//not used
public void addLayoutComponent(Component comp, Object constraints) {
//not used
public void addLayoutComponent(String name, Component comp){
//not used
public void removeLayoutComponent(Component comp) {
* Returns the maximum size of this component.
* @see java.awt.Component#getMinimumSize()
* @see java.awt.Component#getPreferredSize()
* @see LayoutManager
public Dimension maximumLayoutSize(Container target) {
Insets insets=target.getInsets();
int width=0;
int height=vGap;
for(int i=0;i<target.getComponentCount();i++)
Component child=target.getComponent(i);
width=Math.max(child.getMaximumSize().width,width);
height+=child.getMaximumSize().height+vGap;
return new Dimension(insets.left+width+insets.right,insets.top+height+insets.bottom);
* Invalidates the layout, indicating that if the layout manager
* has cached information it should be discarded.
public void invalidateLayout(Container target) {
* Calculates the minimum size dimensions for the specified
* panel given the components in the specified parent container.
* @param parent the component to be laid out
* @see #preferredLayoutSize
public Dimension minimumLayoutSize(Container parent) {
Insets insets=parent.getInsets();
int width=0;
int height=vGap;
for(int i=0;i<parent.getComponentCount();i++)
Component child=parent.getComponent(i);
width=Math.max(child.getMinimumSize().width,width);
height+=child.getMinimumSize().height+vGap;
return new Dimension(insets.left+width+insets.right,insets.top+height+insets.bottom);
* Calculates the preferred size dimensions for the specified
* panel given the components in the specified parent container.
* @param parent the component to be laid out
* @see #minimumLayoutSize
public Dimension preferredLayoutSize(Container parent) {
Insets insets=parent.getInsets();
int height=vGap;
int width=MIN_WIDTH;
for(int i=0;i<parent.getComponentCount();i++)
Component child=parent.getComponent(i);
Dimension d=child.getPreferredSize();
width=Math.max(width,d.width);
height+=d.height+vGap;
return new Dimension(insets.left+width+insets.right+2*hGap,insets.top+height+insets.bottom);//+2*vGap);[email protected] july, 02 2002
* Lays out the container in the specified panel.
* @param parent the component which needs to be laid out
public void layoutContainer(Container parent) {
Rectangle bounds=parent.getBounds();
int x=hGap;
int y=vGap;
for(int i=0;i<parent.getComponentCount();i++)
Component child=parent.getComponent(i);
Dimension prefSize=child.getPreferredSize();
int width=Math.max(bounds.width-2*hGap,MIN_WIDTH);
int height=Math.min(prefSize.height,bounds.height);
child.setBounds(x,y,width,height);
y+=height+vGap;
x=Math.max(x,bounds.width);
parent.setSize(x,y);
int hGap=0;
int vGap=0;
public void setHgap(int hGap)
this.hGap=hGap;
public void setVgap(int vGap)
this.vGap=vGap;
}

First of all when you post code use the [url http://forum.java.sun.com/features.jsp#Formatting]Formatting Tags so the posted code is actually readable.
The point of using a LayoutManager is to let the manager determine the best location for a component based on known information about the component.
If you want to manually position components (not recommended) then you don't use a Layout Manager and instead use [url http://java.sun.com/docs/books/tutorial/uiswing/layout/index.html]Absolute Positioning.
