Hi so I am trying to creat this menu for the game, and when I run the code it is very hit or miss. In the same computer with same screen same OS and everything the same, I might run the code ones and the menu is fine. and then I run it again and the pictures are missalighed or the just disappear and so on. I have tried changing the order of the contentPane.add but and I am out of ideas. What else could it be? Thanks
public static int type(){
// Create a "clickable" image icon
int i =0;
Color c = new Color (0,0,0);

I think the issue is that your are calling frame.setVisible(true) before you are done making changes to frame. If you move this (and maybe the pack() call) pass all your add()s and after you setContentFrame(), then your window will open more reliably.
As for the alignment, that is going to come down to all your setBounds() calls. If you don't need to use setBounds() you should probably look into Layout Managers and nest JPanels for modular sections of you're design (e.g. character info).

I'm trying to transition from the home screen to the option menu through a JButton by adding a JPanel (menu) to the frame and hiding the currently visible panel (background). I'm using an Action Listener to activate the transition. Sometimes when running the code (more like most of the time), some parts of the menu won't appear such as the JComboBox and two of the JLabels. I'm not having an issue with the JSlider though, but I haven't been able to identify the problem for the other components. I tried implementing menu.revalidate() and menu.setVisible(true) at the end of my code, but to no prevail. I also tried doing frame.revalidate() and frame.setVisible(true). Another attempt at fixing this was by moving around the menu.add([insert JLabel/JComboBox]).
The code that I used is as provided
Window.java
JFrame frame;
JPanel background;
JPanel menu;
JSlider difficulty;
JLabel difficultyLabel;
JComboBox exerciseChoice;
JPanel dropDownPanel;
JLabel exerciseChoiceLabel;
JPanel difficultyPanel;
public ActionListener startButtonPressed() throws IOException {
ActionListener temp =
new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
try {
background.setVisible(false);
menu = new JPanel();
menu.setLayout(new BoxLayout (menu, BoxLayout.Y_AXIS));
menu.setBounds(menu.getLocation().x+50, 50, 700, 100);
menu.setBackground(Color.WHITE);
startButton.setEnabled(false);
createDifficultySlider();
createWorkoutDropDown();
frame.add(menu);
frame.setVisible(true);
} catch (IOException r) {}
}
};
return temp;
}
public void createWorkoutDropDown() throws IOException {
dropDownPanel = new JPanel();
dropDownPanel.setLayout(new FlowLayout(FlowLayout.LEADING));
dropDownPanel.setBackground(Color.WHITE);
String[] choices = {"Abs", "Cardio", "Full Body", "Upper Body", "Stretches", "Lower Body"};
exerciseChoice = new JComboBox(choices);
exerciseChoice.setFont(new Font("Verdana", Font.PLAIN, 20));
exerciseChoiceLabel = new JLabel("Workout Options");
exerciseChoiceLabel.setFont(new Font("Verdana", Font.PLAIN, 20));
dropDownPanel.add(exerciseChoiceLabel);
dropDownPanel.add(exerciseChoice);
menu.add(dropDownPanel);
}
public void createDifficultySlider() throws IOException {
difficultyPanel = new JPanel();
difficultyPanel.setLayout(new FlowLayout(FlowLayout.LEADING));
difficultyPanel.setBackground(Color.WHITE);
difficulty = new JSlider(JSlider.HORIZONTAL, 1, 10, 5);
difficulty.setPreferredSize(new Dimension(difficulty.getPreferredSize().width + 60, difficulty.getPreferredSize().height + 5));
difficultyLabel = new JLabel("Difficulty Level (Easy 1- Hard 10)");
difficultyLabel.setFont(new Font("Verdana", Font.PLAIN, 20));
difficulty.setFont(new Font("Verdana", Font.PLAIN, 10));
difficulty.setMajorTickSpacing(1);
difficulty.setPaintLabels(true);
difficulty.setPaintTicks(true);
difficulty.setSnapToTicks(true);
difficultyPanel.add(difficultyLabel, BorderLayout.PAGE_START);
difficultyPanel.add(difficulty, BorderLayout.LINE_START);
menu.add(difficultyPanel);
}
EDIT: I had to throw IOExceptions because I was importing fonts from my drive.
I am trying to make an application, which displays a JLabel and a button, which if clicked switches to another jPanel. For some reason my JLabel is not displaying at all in either case. I would appreciate an expert eye to look over my code and see what I am doing wrong. Thanks in advance.
HomeScreenUI(){
//frame
JFrame frame = new JFrame("Opisa");
//panels, one before button click and one after
JPanel panel = new JPanel();

//jlabel that isnt displaying + dimensions

Dimension size = label.getPreferredSize();
label.setBounds(100, 100, size.width, size.height);
label.setFont(new Font("Helvetica", Font.PLAIN, 70));
//second jlabel that isn't displaying

//adding the labels to the panels

//adding the panel to the frame and setting the size
frame.add(panel);

frame.setVisible(true);
}
Check the label bounds, more specifically its size... try setting some fixed values (great enough to show its content like setBounds(100, 100, 250, 80)).
The preferred size is being retrieved before changing the font size, so it is not big enough to show that big characters. Try changing the font first.
I'm pretty sure I have to make a container and add the labels to the container in the win() and lose() methods. But how should I do this? Also, if you have any other tips to make the code more readable and coherent.
P.S. This is my first time using Java Swing to program graphics, so I know the code is very messy. I mostly just care if the program works the way I want it to...
P.P.S There were a few class variables, but StackOverflow wouldn't let me post them

How to add JLabels to JFrame?
I'm pretty sure I have to make a container and add the labels to the container in the win() and lose() methods..
I wouldn't use that approach. A label without text or icon is invisible (unless it has a visible border). So create and add the label at start-up with no text. When a win or loss is achieved, set some text.
If the layout refuses to add space for the label without any text (e.g. in the PAGE_START of a BorderLayout it would have no height), add some text to it before pack() is called, and set it to no text afterwards.
How do I dispose my second frame while retaining my MainFrame?
I have a JFrame( CCurrencyConverterFrame) that I call from the Main Frame.
JMenuItem mntmCurrencyConverter = new JMenuItem("Currency Converter");
mntmCurrencyConverter.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
CCurrencyConverterFrame frame = new CCurrencyConverterFrame();
myFrame = frame;
JPanel contentPane = new CCurrencyConverter(myFrame);
frame.setContentPane(contentPane);
frame.setVisible(true);
}
});
In CCurrencyConverterFrame.java,
public CCurrencyConverterFrame() {
setFont(new Font("Dialog", Font.BOLD, 12));
getContentPane().setFont(new Font("Tahoma", Font.BOLD, 16));
setTitle("Currency Converter ");
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
setBounds(100, 100, 469, 470);
//Center
setLocationRelativeTo(null) ;
}
I have tried using JFrame.HIDE_ON_CLOSE but it still terminates my application. What can I do to resolve this?
Hi I'm having trouble in my code. I can't call or display my JPanel(TruthTable) inside my splitpane in the Minimize class when I click the button and Keypressed(Enter).The problem is in the class Minimize
*UPDATE: I'have solved my problem regarding to diplaying the panel my next problem is when I call the constructor the text in the panel should be updated.I also change the setText to append 'coz they say that JPanel doesnt support setText.I've already used,validate,repaint method but no luck in updating the textArea.
Heres my code for class Minimize:
package splashdemo;
public class Minimize extends JPanel implements ClipboardOwner
{
simButton.addActionListener(new ActionListener()
{ public void actionPerformed(ActionEvent ae)
{
LogicGates lg= new LogicGates();
lg.geth();
sim s=new sim();
s.InputExp(lg.g,lg.g1);
s.menu();
s.setSize(700,700);
s.setVisible(false);
Frame f = new Frame();
Panel panel = new Panel();
f.add(BorderLayout.SOUTH, panel);
f.add(BorderLayout.CENTER, new sim());
f.add(BorderLayout.SOUTH, panel);
f.setSize(580, 500);
panel.add(s.button);
f.show();
f.setVisible(false);
JOptionPane.showMessageDialog(null, b);
ex=b;
cAppend();
JOptionPane.showMessageDialog(null, ex1);
InToPost(ex1);
foutput= doTrans();
JOptionPane.showMessageDialog(null, foutput);
TruthTable_1 kl = new TruthTable_1(foutput);
Minimize mi = new Minimize();
s.InputExp(lg.g,lg.g1);
s.menu();
lg.gatessplit = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, mi, lg.p1);
//here's the splitpane where I should display the TruthTable_1 panel but it doesn't diplay
lg.p1.add(lg.gatessplit = new JSplitPane(JSplitPane.VERTICAL_SPLIT, s,kl));
lg.gatessplit.setOneTouchExpandable(true);
lg.gatessplit.setDividerLocation(250);
lg.gatessplit.setPreferredSize(new Dimension(900, 500));
lg.createAndShowGUI();
}});
}
Heres my code the TruthTable_1:constructors
public TruthTable_1() {
super();
