I can't find anyone who has this same problem, so it might just be a simple fix, but I'm creating a Jeopardy game in Netbeans. I created a JPanel Form to design each of the individual squares, and then I added 36 of them (for the 6x6 board) to another JPanel Form which represents the board. That works great, but the problem is that after I add all 36 squares to the board, they are stuck in the state at which I added them. If I change the position or color of a label in the Question JPanel Form, it does not update in the Jeopardy Board JPanel Form. I don't want to re-add 36 Questions and rename all the variables every time I make a change to a sub-component. Is there a way to keep it all in sync?
If I change the position or color of a label in the Question JPanel Form,
1). labels are non opaque which means changing the background color will have no effect. You need to make the label opaque when you create it when you want to alter the background:
label.setOpaque( true );
2) Once you set up your jeopardy board you should have no need to change the position of the label. Once the question is answer, I would just clear the text in the label by using:
label.setText("");
For each new round of jeopardy again all you need to do is reset the background for every label and then reset the text for every label. There should be no need to recreate all the labels.
You could try calling the revalidate() method of the JPanel.
Consider refactoring and renaming all folders you personally created in the project. This should resolve the issue.

Hey all I am having some trouble trying to get my jlabels to line up the way I want them to. I am using 3 panels (Title Panel, Display Panel, and Button Panel) Inside of my DisplayPanel I have a JtextField, 3 jlabels and the next thing I want to have happen is for the rest of my JLabels which happen to be ImageIcons to be in a set location inside of my panel, which is in boxLayout.
MasterOffense1 = new JLabel(Mastery1);
MasterOffense1.setLocation(400, 100);
MasterOffense1.setSize(25, 25);
MasterOffense1.setToolTipText("<html>"+"Double-Edged Sword<br> Melee- Deal an additional 2% damage and receive an additional 1% damage<br> Ranged- Deal and additional 1.5% damage and receive an additional 1.5% damage"+"</html>");
DisplayPanel.add(MasterOffense1);
MasterOffense2 = new JLabel(Mastery2);
MasterOffense2.setLocation(400, 130);
MasterOffense2.setSize(25,25);
MasterOffense2.setToolTipText("<html>"+"Fury<br> Rank-1: +1.25% Attack Speed<br> Rank-2: +2.5% Attack Speed<br> Rank-3: +3.75% Attack Speed<br> Rank-Max: +5.00% Attack Speed"+"</html>");
DisplayPanel.add(MasterOffense2);
There is code for the 2 JLabels with ImageIcon inside them and they keep showing up right below each other. I have no idea how to make this happen and I am completely stumped..
Any help would be appreciated. Thanks!

Then is sounds like you are using a vertical BoxLayout.
If you want the labels to be displayed horizontally, then you can add the labels to a panel and then add the panel to your "displayPanel".
That is you can nest panels that use different layout managers to get your desired layout.
Also, use standard Java variable names. Variable names should NOT start with an upper case character.
I just recently started using Swing to create GUIs for programs, and it's been pretty fun to mess around with so far. However, I'm having an issue with a JPanel with the layout set to gridLayout. Right now it looks like this:
The grid on the right is a JPanel set to a GridLayout, with each cell being a bordered JLabel. The options on the left are also inside a JPanel, and the left JPanel and right JPanel are nested in a GridBagLayout set on a JFrame.
Essentially, my problem is that I want to "scale" the grid on the right so that each cell is a certain height and width. The grid itself will have a variable number of rows and columns, which are set when the program first starts up. Eventually, I plan to have the right JPanel in a JScrollPane (if that's how that works...), so I'm not really concerned about whether or not all of the grid shows up onScreen.
I tried setting the fill value for the gridLayout to "BOTH" and it gave me the following result:
This is closer to my intention, but I wanted the actual ImageIcon in the JLabels to fill the entire JLabel. Additionally, I would want the JLabels to be the same height and width. However, I don't know exactly how to do that. I've been messing around with it for a while now, and I'm not sure if I'm just too much of a noob with Swing, or if I'm missing something in the documentation.
In the end, I'd like the grid cells to be a fixed height and width, no matter the number of cells, and no matter whether it goes offscreen or doesn't fill it.
(Also, I just thought, maybe it's not the best idea to code this and then shove it in a JScrollPane later and expect it to perform the same.... I guess I'll just see what happens.)
but I wanted the actual ImageIcon in the JLabels to fill the entire JLabel.
Check out Darryl's Stretch Icon which will allow the icon to resize to file the space available for the JLabel.
So, I'm making a program, and on the program, it displays your health in this format:
Health : 82/82
When you take Damage, I ask the program to update the JLabel, and it would display that you took damage like this
Health: 60/82
The JLabel is a public variable, and is only being created once,
public JLabel UIHealth = new JLabel();
and from then on is updated with the below code.
Here is the code I use to update the UIHealth JLabel updating the text after an action occures:
UIHealth.setText("Health: "+Health+"/"+PlayerHealthBar.getMaximum()+"");
Is there a simpler way to display text that will be updated?
Does it matter that my Frame and ALL panels are set to be transparent to see the image behind it that acts as a HUD?
Here is the code I applied to everything that is transparent, but still interactive.
public Color Clear = new Color(0,0,0,0);
and I would of course call Clear when using the .setBackground component.
here is an image of after taking a bit of damage (4-5 hits) looks on the UI. (Take note of how the text just stacks on top of itself)
Thanks in advance for all your time.
Please let me know and ask me if something seems unclear, or you need other snippets of my program.
You have a JPanel that you are adding your label to. You need to call myPanel.setOpaque(false); after creating it.
I have this idea that I want to implement into my project.
I know it is doable, but I do not know where to start.
I have a JPanel,
in there will be a Jbutton , a JLabel, and a ComboBox, and a JtextArea.
Originally, there is only the JtextArea and JButton on my panel.
When I hit the button, the Combobox, and JLabel will slide in or fade in, or drop down, or event rotate in.
So how would I accomplish this, I know I have to use graphic g, repaint(). It is easy to do the Jlabel but what about the combobox.
Should I add the combobox and Jlabel into a separate Jpanel and make that panel animated in. but even that, I do not know how to make this panel in motion.
Please help me on this, and example would be appreciated
Thank you!
To get started, you'll probably need to research these terms:
Slide layout (thanks #Andrew Thompson)
setLocation
TimerTask (I think, or maybe just Timer)
clobbering graphics objects
Once you know about that stuff, you'll be in a position to make the design decisions that you're asking about.
It sounds like you'll have a child panel with a slide layout. Try not to use null layouts when possible.
You'll set its location or style per each tick in a timer task.
If you're setting a style, you'll need to clone your graphics object to avoid "clobbering" it - that is, work on a copy of the graphics object, so the original isn't changed or repainted accidentally while you're working on it.
I have a JPanel that contains a bunch of Swing JComponents, including some JSeparators that may be only one or two pixels wide. I want to let my users drag the items around, but it can be rather difficult to hit a one or two pixel wide line. Is there a way that I can give those JSeparators a wider "target" region for mouse clicks? The only thing I've been able to think of is to have my mouse handler listen for clicks on the JPanel, and if it gets any, run through the list of JSeparators, looking to see if any of them are within a couple of pixels of the mouse click.
Should that work? Is there a better way?
Add a fat EmptyBorder to the component.
If it already has a border, you can set a compound border using the current border then the empty border, or simpler, add the empty border (and listener) to a panel that contains the component. The latter will work better for components such as JButton, which have borders that change according to state and focus.
