I have a custom button class that I created that extends JButton. When I add this to a JFrame, I get this:
But when I place this custom button into the frame with BoxLayout, the button becomes smaller and is not desirable this way:
Here is my code for the frame:
Test.java
import javax.swing.BoxLayout;
import javax.swing.JFrame;
public class Test {
public static void main(String[] args) {
JFrame frame = new JFrame();
//When you uncomment this, the button is sized really small
//frame.getContentPane().setLayout(new BoxLayout(frame.getContentPane(),BoxLayout.PAGE_AXIS));
frame.add(new CButton("Hello"));
frame.pack();
frame.setVisible(true);
}
}
And here is the code for the custom button, CButton:

Is there a way I can fix this and make it the full size?
Override the getPreferredSize(). BoxLayout respects preferred sizes. If you don't the preferred size will be determined by the text. It is bigger in the frame because the default BorderLayout of the frame doesn't respect preferred size, and will stretch the button. Another thing you can do instead is set bigger margins and/or bigger font, as that will also increase the preferred size. So you have a few options/things to consider
Have a look here as which layout respect preferred sizes and which ones don't. Another always good resources is Laying out Components Within a Container

I am display an image on JPanel and on that image i am creating a Grid of 8*8 by setStroke of Graphics2D. Now when i zooming that grid lines by setting setStroke it does not work for all images. I am thinking that this problem is associated with resolution of images. How can i solve this problem
BufferedImage bi; //loading buffered image some how
JCombobox jComboBox; //creating combobox having different zoom factor
Dimension screen = Toolkit.getDefaultToolkit().getScreenSize();
int gridLinesThikness = (int) ((float) jComboBox.getSelectedIndex() * (float) (bi.getWidth() / (float) screen.width));
if (gridLinesThikness < 1)
gridLinesThikness = 1;
g2.setStroke(new BasicStroke(gridLinesThikness));

I am making a button where when you click on it it changes the text. But when I click on the button and change the text, the button does not change size according to the text. Instead, it gets smaller and attempts to make that "..." thing when it does not have enough room. Here is my code:

You call
setPreferredSize(new Dimension(
nWidth + ((2 * getFont().getSize()) / 5), nHeight
+ ((2 * getFont().getSize()) / 5)));
in the constructor, but never change it. This means that each time the layout manager asks the component what size it would like to be, it always gets the same value.
A preferred solution would be to override getPreferredSize and calculate the size there, if it's not to complicated or time consuming
The next question is why are you going to all this extra effort. Basically, you should simply allow the parent JButton to provide its preferred size and add your requirements around it, or simply use the margins properties or even a Border
You're KeyListener also seems useless as this is the default behaviour of the button anyway and in any case, key bindings would be a preferred solution
My first thought was that it had to do with your humongous CButton implementation. At least, copy/paste of your code created a working application. That's a big plus in my book.
When I simply replaced the strange nWidth calculation in the setText() method with:
int nWidth = 100;
The size was increased after a click and showed an "f", which I assume is what you wanted.
So, I can't really say how to calculate the width, but at least you know where to look and which line to change.
I have a JButton that when I call setText(), the text does not update. But as soon as I hover over the button, it updates. How can I fix this so that when I call setText(), the button updates? I will just post the methods that the EDT takes to get to it. It goes in order :)

I fixed it. I needed to add a repaint to the container for the button. Simple as that!
button.setText("Some Text");
buttonContainer.repaint();
I'm making my first steps with desktop GUI design. What I'm trying to achieve is displaying in one of table columns. I want them to be visually attractive and also clickable.
At first, I thought that it's possible to do that with JButton with some hacks, as suggested in this thread. But then I realized that I don't know how to manage dynamic width of labels and stretching the graphics to fill buttons in 100%.
I want to achieve something similar to image below. In HTML+CSS it's very easy, each tag:
has left edge as graphics
has repeatable 1px wide background
has right edge as graphics
But how to do that in Java?
info: I don't care if this is a JButton or not, as long as it's nice, clickable and draggable.
UPDATE
Mockup below represents what I want to do. It involves JTable or multiple JLists as well as those tags floating left next to the word. It's easy to do in HTML+CSS, but almost impossible for me to do that in Java.
I have no doubt there are multitudes of ways to achieve this, a better way would be to simply write a UI delegate, but let's try and keep it basic for the moment...
(I've updated the button code, so I've included it in the update)
The problem you have is JTable just isn't designed to do what you are trying to. Grouped rows and variable row heights are not easily achieved.
This is just an example, but what I've done is generate a series of compound components which "mimic" your basic requirements...

use javafx buttons rather than swing.
javafx buttons have css properties.
Based on your requirements it does seem like JButton is a good starting point because it has most of what you want.
As far as the width goes, you will most likely need to subclass JButton so that you can you can update the width in the constructor, something like this:
private static class FancyButton extends JButton{
public FancyButton(String name) {
super(name);
//Calculate new width
setPreferredSize(new Dimension(newWidth, 30));
}
}
Or have a method that sets up your buttons that determines and sets the width.
As you want to use these in a JTable, you'll need a custom renderer that draws the button with or without the number showing. The numeric value and state should be stored in your TableModel. To get the behavior of a button, you'll need a custom editor, perhaps one returning an instance of JToggleButton. In this example, an instance of JCheckBox (a subclass of JToggleButton) is used to display both state and value in a column.
I can't seem to work out what the problem is here.

I run this and end up getting a grey screen. Any help?
ImageEntity is basically an Image Wrapper type thing for BufferedImage. The problem seems to be in the paintScore() method, as if I comment off the calling of the method, it works as intended. This is for a Pong type game I am trying to make.
Oddly, this single change (after a number of changes to get it to compile) fixes the stated problem:
Font scoreFont = new Font("Arial", Font.PLAIN, 72);
remove paintscore from gamepanel() and add it in main after mainpanel.add(gp)
gp.paintScore(gp.gameScreenGraphics);
there is something else wrong with your code though
change font size to 24
