FlowLayout and lightweight IDEs

Hi All,

This Q is about using a FlowLayout. The lineup of labels and
textfields should be made in two horizontal rows by the size given in
the program. I tested this with 3 lightweight IDE's All use the same

With two of them, on a initial run, show no labels and textfields
items but the frame is in the correct size. If I open the screen to
the full width using the icon , all items are visible. If I then
click the icon to diminished size, using top of the frame menu bar,
all the items are there and in the intended line up. The third IDE
opens the program and right away everything is there in the correct
size and placement. Is the problem in the IDE's? Can the two that show
nothing on the initial run have a line of code added to make it appear
correct without resizing the screen manually from the app menu frame?


 Here's the program:

import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.text.SimpleDateFormat;
import java.net.*;
import java.io.*;
import java.util.*;
import javax.swing.*;
import javax.imageio.*;

public class GoogleDrawImage
  public static void main(String[] args)
    JFrame frame = new ImageFrame();
class ImageFrame extends JFrame implements ActionListener {
  BufferedImage image;
  JLabel lbleGoogleInstr,lbleFieldcht,lbleFieldchs,lbleFieldchd,
     lbleFieldchm, lbleFieldchf;
  JButton btnGetGoogleApis,btnClose;
  boolean isOneDone = false;
  public ImageFrame()
    super("Image from Developer's Guide - Google Chart API - Google");
    super.setSize(800, 600);
    Container con = getContentPane();
    con.setLayout(new FlowLayout());
    addressField = new JTextField(20);
    appendFieldcht = new JTextField(8);
    appendFieldchs = new JTextField(8);
    appendFieldchd = new JTextField(8);
    appendFieldchm = new JTextField(8);
    appendFieldchf = new JTextField(8);
    lbleGoogleInstr = new JLabel("Complete These to Get Drawing:");
    lbleFieldcht = new JLabel("cht is: ");
    lbleFieldchs = new JLabel("chs is: ");
    lbleFieldchd = new JLabel("chd is: ");
    lbleFieldchm = new JLabel("chm is: ");
    lbleFieldchf = new JLabel("chf is: ");
    btnGetGoogleApis = new JButton("GetGoogleApis");

    btnClose = new JButton("Close Application");
    //Add Components to this container, using the default FlowLayout.
    add (lbleGoogleInstr);
    add (appendFieldcht);
    add (lbleFieldchs);
    image = null;

  public void actionPerformed(ActionEvent e) {
    String urlGoogleDrw = addressField.getText()+"cht="+
      appendFieldcht.getText().trim()+"&chs=" +

    if (e.getActionCommand().equals("GrabItAll")) {
      //nothing here so let it fall through and go on
    else if (e.getActionCommand().equals("close")) {
    try {
      // Read from assembled URL
      URL url = new URL(urlGoogleDrw);
      image = ImageIO.read(url);

    } catch (IOException et) {
    try {
      Date dNow = new Date();
      SimpleDateFormat formatter = new SimpleDateFormat
      String df = new String(formatter.format(dNow));
      File file = new File("C:/Documents and "+
      "Settings/bH/My Documents/BlueJ Projects/Viewer/imageDate "
      + df + " FromGoogle.png");
      ImageIO.write(image, "png", file);
    catch (IOException em) {
  public void paint(Graphics g)
    g.drawImage(image, 50, 110, null);
    if (isOneDone = false){
      System.out.println("See C:/... " +
      "/BlueJ Projects/Viewer/images/imageDate yyMMddHHmmssZ
      isOneDone = true;
