How does one delete a button ?
Posted by Avin Sinanan on February 15, 2002 at 10:25 AM
Hello does anyone knwo how to delete a button? For example consider the following senario - You have a JFrame, JPanel and a JToolbar attached to the frame
and on the toolbar you have 2 buttons , one when clicked adds a button to the JPanel. The button that is added can move around and if you press the button again another the button is added.
The second button deletes the selected button.
Below I have included the code that addes the button and stuff. Does anyone know how to complete the code that deletes a the selected button on the JPanel? Any help would be greatly appreciated... thanks... Here is the code --> import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
import java.util.*;
import java.awt.event.MouseListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionListener; class DeleteButton
{
public static int i =0 ;
public static void main(String[] args)
{
JFrame frame = new JFrame() ;
final JPanel pane = new JPanel();
pane.setLayout(null);
JToolBar tool = new JToolBar();
JButton addButton = new JButton("Add");
JButton deleteButton = new JButton("Delete");
addButton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
JButton button = new JButton("" + i);
pane.add(button);
button.setBounds(10,90,80,50);
button.addMouseMotionListener(new MouseMotionAdapter() {
public void mouseDragged(MouseEvent me) {
me.getComponent().setLocation(me.getComponent().getX() + me.getX(),
me.getComponent().getY() + me.getY());
}
});
i++ ;
}
});
tool.add(addButton);
tool.add(deleteButton);
pane.updateUI();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(pane);
frame.getContentPane().add("North", tool);
frame.setSize(500,500);
frame.setVisible(true);
}
}
