Hi all,
I am facing critical problem in the follwing application. The problem is at a point two text fields getting request foucs. So I unable to edit the one.
code>>
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class TestFocus extends JFrame
{
JTextField txtOne,txtTwo,txtThree;
JButton btnSet;
TestFocus()
{
txtOne = new JTextField(15);
txtTwo = new JTextField(15);
btnSet = new JButton("Set");
btnSet.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent ae)
{
setClicked();
}
});
this .getContentPane().setLayout(new FlowLayout());
getContentPane().add(txtOne);
getContentPane().add(txtTwo);
getContentPane().add(btnSet);
setSize(200,150);
setLocation(150,150);
setVisible(true);
}
void setClicked()
{
int out = JOptionPane.showConfirmDialog(this,"Do you want exit?", "choose one", JOptionPane.YES_NO_OPTION);
if(out == 0)
{
String sOne = txtOne.getText();
String sTwo = txtTwo.getText();
if(sOne.equals(""))
{
JOptionPane.showMessageDialog(this, "One is empty", "information", JOptionPane.INFORMATION_MESSAGE);
txtOne.requestFocus();
}
else if(sTwo.equals(""))
{
JOptionPane.showMessageDialog(this, "Two is empty", "information",JOptionPane.INFORMATION_MESSAGE);
txtTwo.requestFocus();
}
else
{
System.exit(0);
}
}
}
public static void main(String[] args)
{
new TestFocus();
}
}
Do the following steps,
1.Enter some values in the first text field.click on the set button with out entering any values in the second text field.
2.This will popup a dialog with "Do you want to exit?".
3.click on the yes button. This will popup a another optionpane with the message that "Two is empty". Click ok, the focus will go to second text area.
4.DON'T ENTER ANYTHING IN THE TEXTFIELDS JUST CLICK ON THE FIRST TEXT FIELD AND THEN CLICK THE SET BUTTON.
5.This will popup message as in the 2nd and 3rd step but in the end you can see both the textfiels got focus.
I can't enter any values in the first textfield after that.
I am running this code on Windows2000,jdk1.3.1

This bug is in Sun's bug database here. It has been fixed in 1.4, and there are a few workarounds for 1.3 that various people have posted in the thread under the bug report.
