Panel In JFrame Which Consists Of TextField
Apr 20, 2014
I have a Panel in JFrame which consists of a TextField. I want this text field to be initially focused when GUI starts so that i should not have to first click in it before writing something.
I've tried:
textField.requestFocus();
textField.requestFocusInWindow();
textField.grabFocus();
but of no use. What should i use ?

Okay so I have the codes all written but I didn't really look at that I had to color the center of the frame. I have base code for it but it just doesn't want t ocolor the cnter frame for me for some reason. I have been looking around and still am having problem with it only coloring the center of the frame.
Java Code:
import java.awt.event.*;
import javax.swing.*;
import java.awt.*;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
public class MenuColors {

I want to switch panel on click of a button and code for switching panels is written in update method (Which gets called from notify observer of another class as part of Observer pattern.
unoGameController.playGame(playerFirst.getText(), playerSecond.getText());
playGame in Panel 1 of class 1 calls another class (class 2)and data comes in update method of class 1(Observer interface).
Now for switching panels code is in gameControllerDataProcessing . I am not able to switch the panels when this functionality runs.
However if i dont call the unoGameController.playGame(playerFirst.getText(), playerSecond.getText() and directly call the update method or directly write the switching panel code . then it works fine.
btnNewButton_1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if((!(playerFirst.getText().equalsIgnoreCase("") ||playerSecond.getText().equalsIgnoreCase(""))&&(!playerFirst.getText().equalsIgnoreCase(playerSecond.getText())) ) ){
unoGameController.playGame(playerFirst.getText(), playerSecond.getText());

When in panel2 i type something in the search bar and then i move mouse cursor to panel1 and try to edit a JTextField input for example as in the picture 0.0 nothing happens but the mouse cursor is correctly show up in the JTextField.. What seems to solve the problem is to click anywhere outside of the application window.. but of course this is not a solution !

I am working on a keypad for a phone app for school. I cannot get the numbers from the keys to show up in the textField. I have made multiple tweaks, but think maybe my case statement is the problem?We did a calculator application in the class, so I have based my code off of that. Although the telephone keypad seemed much simpler to code, I can't seem to get the numbers to show up.
public void actionPerformed(ActionEvent e) {
//test for button clicks
foundKey = false;
//search for clicked key
for (int i=0; i<keys.length && !foundKey; i++)

What would be the simplest way of creating a Dialog that can add TextField dynamically based on whether a radio button option from the dialog box is selected. I thought of JOptionPane.showMessageDialog and adding a JComponent though I would not be able to add a TextField on the fly and I would not be able to add ActionListeners. The dialog would initially contain some radio buttons, labels and textfields.
