Adding icons to jTable in different rows
java,image,swing,jtable,imageicon
This is solved easily by simply making sure that the column for the icons returns Icon.class in the table model's getColumnClass(...) method.

Adding an image into a GUI made with Eclipse

Java resize an image
You can paint the image in a JPanel as the whole panel. Then whenever the panel is resized, the image will be resized along with it. Here's a quick-n-dirty runnable demo: import java.awt.BorderLayout; import java.awt.Graphics; import java.awt.image.BufferedImage; import java.io.File; import java.io.IOException; import javax.imageio.ImageIO; import javax.swing.JFrame; import javax.swing.JPanel; public class ImgFrame...
Getting errors trying to use KeyListeners and ImageIcons?
java,swing,graphics,stack-overflow,imageicon
The problem is that you have infinite recursion in your constructors. Layout() calls addKeyListener(new Move());, and Move extends Layout, so Move's constructor also calls Layout(), which in turn calls Move(). You need to refactor your code to avoid that. A simple approach would be making Move not extend Layout, and...
Resize an ImageIcon for an JLabel

Java paint icon not working for background image
java,swing,paintcomponent,imageicon
Now paintIcon has x, y parameters not width/height, which seems to be the error. In general I somewhat dislike the paintIcon method, and would store the Image and do: @Override public void paintComponent(Graphics g) { super.paintComponent(g); g.drawImage(backgroundImg.getImage(), 0, 0, null); } ...
How to sort a JTable column that contains icons?
java,swing,jtable,awt,imageicon

The 3rd column is sorted ascending. import java.awt.*; import java.awt.image.BufferedImage; import javax.swing.*; import javax.swing.border.EmptyBorder; import javax.swing.table.*;...
Image not showing in Jtable with renderer
java,swing,jtable,imageicon,tablecellrenderer

Java add icon to JCalendar
java,swing,imageicon,jcalendar
Adding an icon to the buttons of a JDayChooser is not supported. You'd have to extend JDayChooser and modify one of the buttons in the protected array named days.

Unable to change button text to icon immediate after click button in java swing
java,swing,jbutton,embedded-resource,imageicon

Where do I get the iOS toolbar icons for up/down arrow?
ios,iphone,objective-c,imageicon

image doesnt shows on JLabel when click on next button, using java Swing
Add frame.revalidate() and frame.repaint() after frame.getContentPane().add(image); Swing is lazy when it comes to performing updates to the layout hierarchy, which is good thing, imagine adding a few dozen components and having the entire component hierarchy been updated for each one. So, instead, you need to update the container manually when...
