I am writing a small program that converts files, and I wanted to have a box pop up that asks the user to please wait while the program loops through and converts all the relevant files, but I am running into a small problem. The box that pops up should have a JLabel and a JButton, while the user is "waiting" I wanted to display a message that says please wait, and a disabled "OK" JButton, and then when its finished I wanted to set the text of the JLabel to let them know that It successfully converted their files, and give them a count of how many files were converted. (I wrote a method called alert that sets the text of the label and enables the button.) The problem is That while the program is running, the box is empty, the Label and the Button are not visible, when it finishes, label appears with the final text that I want and the button appears enabled. I am not sure exactly what is going on, I tried changing the modifiers of the JLabel and JButton several times but I cant seem to get it to work correctly. Here is the code for the box that pops up, any help is greatly appricated.
import java.awt.BorderLayout;
import java.awt.FlowLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class PleaseWait extends javax.swing.JFrame{
private static final int height = 125;
private static final int width = 350;
final static JLabel converting = new JLabel("Please Wait while I convert your files");
private static JButton OK = new JButton("OK");
public PleaseWait(){
// creates the main window //
JFrame mainWindow = new JFrame();
mainWindow.setTitle("Chill For A Sec");
mainWindow.setSize(width, height);
mainWindow.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
// creates the layouts//
JPanel mainLayout = new JPanel(new BorderLayout());
JPanel textLayout = new JPanel(new FlowLayout());
JPanel buttonLayout = new JPanel(new FlowLayout());
// Sets Text //
converting.setText("Please wait while I convert your files");
// disables button //
OK.setEnabled(false);
// adds to the layouts //
textLayout.add(converting);
buttonLayout.add(OK);
mainLayout.add(textLayout, BorderLayout.CENTER);
mainLayout.add(buttonLayout, BorderLayout.SOUTH);
// adds to the frame //
mainWindow.add(mainLayout);
// sets everything visible //
mainWindow.setVisible(true);
}
public static void alert(){
OK.setEnabled(true);
String total = String.valueOf(Convert.result());
converting.setText("Sucsess! " + total + " files Converted");
}
}
Okay here's the issue. You are extending the JFrame . That means your class IS a JFrame.
When you create the PleaseWait frame you don't do anything to it. This is the empty box you are seeing. You are instead creating a different JFrame in your constructor. Remove your mainWindow and instead just use this. Now all of your components will be added to your PleaseWait object. That should fix your blank box issue.
You need an application to create your frame first. This is a simple example of such application.
import javax.swing.UIManager;
import java.awt.*;
public class Application {
boolean packFrame = false;
//Construct the application
public Application() {
PleaseWait frame = new PleaseWait();
//Validate frames that have preset sizes
//Pack frames that have useful preferred size info, e.g. from their layout
if (packFrame) {
frame.pack();
}
else {
frame.validate();
}
//Center the window
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Dimension frameSize = frame.getSize();
if (frameSize.height > screenSize.height) {
frameSize.height = screenSize.height;
}
if (frameSize.width > screenSize.width) {
frameSize.width = screenSize.width;
}
frame.setLocation((screenSize.width - frameSize.width) / 2, (screenSize.height - frameSize.height) / 2);
frame.setVisible(true);
frame.convert();
}
//Main method
public static void main(String[] args) {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
}
catch(Exception e) {
e.printStackTrace();
}
new Application();
}
}
You have to slightly modify your frame to add controls to the content pane. You can do some work after frame is created, then call alert.

I am currently working on my school project to practice vocabulary, I have a method in my GUI that creates new vocabulary and the name of the list, I wanted to create a button that adds more Panels with input fields just this prototype image.
My idea is that when the user clicks
AddMoreButton it will add one JPanel just like P Panel, then the user can write vocabulary to send it to my database, is it possible to create something that?, I tried looping the P panel but it did not not change, any help would be appreciated.
private JPanel SetUpCreate() {
JPanel createPanel = new JPanel();
nameListInput = new JTextField(INPUT_FIELD_WIDTH);
termInput = new JTextField(INPUT_FIELD_WIDTH);
defintionInput = new JTextField(INPUT_FIELD_WIDTH);
p = new JPanel();
doneCreate = new JButton("Done");
doneCreate.addActionListener(new DoneCreateButtonAction());
addMoreButton = new JButton("Add");
addMoreButton.addActionListener(new AddMorePanelsListener());
p.setBorder(new BevelBorder(BevelBorder.RAISED));
p.add(termInput);
p.add(defintionInput);
JScrollPane pane = new JScrollPane(p);
createPanel.add(nameListInput);
createPanel.add(p);

What I understand from your question is that you want to add another panel every time the user clicks the Add button and the panel to add contains fields for entering a word and its definition.
I see JScrollPane appears in the code you posted in your question. I think this is the correct implementation. In the below code, every time the user clicks the Add button I create a panel that contains the fields for a single word definition. This newly created panel is added to an existing panel that uses GridLayout with one column. Hence every time a new word definition panel is added, it is placed directly below the last word panel that was added and this GridLayout panel is placed inside a JScrollPane. Hence every time a word definition panel is added, the GridLayout panel height increases and the JScrollPane adjusts accordingly.

As your code is not an Minimal Reproducible Example, I cannot provide further assistance than this:
Red part: Your main JPanel with BoxLayout
Green part: another JPanel with your JTextField in it.
Purple part: JScrollPane
Blue parts: custom JPanels with 2 panes in them, one on top for the number, one on the bottom for both JTextFields and icon, so I would say GridBagLayout or BoxLayout + FlowLayout
Orange part: JPanel with GridBagLayout or FlowLayout
Each time you clic on the + icon, you just create a new instance of the custom blue JPanel and that's it.
I've been having some (very annoying) trouble with these scripts that I've created.

I'm trying to call the file "progressbar" to the Sburb file but when I do, it gives me just the simple JFrame of this (not fixed):
http://imgur.com/1aAmPwJ
And when I get rid of the "frame.getContentPane().add(bar);" in Sburb.java, it gives me this (fixed, kind-of):
http://imgur.com/15aGtT2
How do I fix this? I've looked everywhere and yet I still can't figure it out! I also can't seem to figure out how to align the bar directly below the gif.
frame.getContentPane().add(page);
frame.getContentPane().add(bar);
The content pane of a JFrame is a set to a BorderLayout which can only accept one component in any one of the border layout constraints. Given no constraints were supplied here, the JRE will try to put them both in the CENTER.
For this, and a variety of other reasons, I would advise to ignore the existing content pane, arrange the entire GUI (as many panels as it consists of) into another panel (let's call it ui) then call
frame.setContentPane(ui);
EDIT: leaving short code which shows issue:
Then label.setText("") is called and it has to change the text, i.e. scaler overcame 50 barrier the label dissapears for the mousewheelevent -> re-emerges on next event. Also a problem of the label not being present on the Load-up.
In actual program labels stack together in 1 spot if any of them has .setText() changing value or .setVisible changing (These two methods I need to be able to use without affecting labels positioning)

You don't have the package name in your applet. Consider changing
code="Reverser.class"
to
code="Applets.Reverser.class"
and making sure that the class file is in the Applets subdirectory relative to the HTML file. Or even better, create a jar file.
Also you need to post the error messages that the browser is giving you. You could have a version incompatibility for all we know.
I have a value called 'AmountWrongGuessed' that gives the amount of wrong guesses the users puts while guessing a word.
Each times the word is not found in the arraylist the AmountWrongGuessed goes ++. (tested this wih a println and it works properly)
Now the problem is each time the AmountWrongGuessed goes 1 up it should display a ImageIcon.
But insteed it displays the last image icon all the time, and skips the other icons.
I use no layout mananger (its set to null, if this makes any difference in the total picture setLayout = null)
Also while initialising this game the amountwrongguessed is default 0, yet it does not display the first imageicon either. (i used different labels before to add each icon on the same position but then i had the problem only the first image displayed and nothing changed).
public HrView(Hrgame hg) {
this.hg = hg;
CreateComponents();
SetLayoutComponents();
UpdateComponents();
AddListeners();
}
Creation of the images:
private void CreateComponents() {
hang0 = new ImageIcon("hang0.gif");
lblHang = new JLabel(hang0);
lblHang.setLocation(60, -10);
lblHang.setSize(200, 200);
hang1 = new ImageIcon("hang1.gif");
lblHang = new JLabel(hang1);
lblHang.setLocation(60, -10);
lblHang.setSize(200, 200);
hang2 = new ImageIcon("hang2.gif");
lblHang = new JLabel(hang2);
lblHang.setLocation(60, -10);
lblHang.setSize(200, 200);
}
private void AddListeners()
{
btnCheck.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
hg.Input(tfToGuessInput.getText().toLowerCase());
Pictures();
lblHang.updateUI();
}
});
}
private void Pictures()
{
//works, does increment
System.out.println(hg.getAmountWrongGuessed());
if (hg.getAmountWrongGuessed() == 0) {
add(lblHang);
}
if (hg.getAmountWrongGuessed() == 1) {
add(lblHang);
}
if (hg.getAmountWrongGuessed() == 2) {
add(lblHang);
}
}
After CreateComponents() your attribute lblHang references the label you created last (the one containing image hang2.) In order to use the 3 labels later on, you need to have 3 label attibutes which you can then use in Pictures().
Btw, in Java the naming convention is that method names start with a lowercase character.

I think if you want to switch images, using jlabels, the above codes would help. It would help to rotate jlabels containing images but this codes are not optimized.
