Insert a GIF image into JFrame and make it visible and invisible on demand
java,swing,jframe,paint,imageicon
I want to achieve this by making my current frame view.getFrame2() invisible and make a view.getFrame3() visible. Don't be hiding/showing different windows. Users don't like frames disappearing. Instead you can simply display a modal JDialog containing your image on top of your main frame. Or another approach is to...
Java: Can't repaint ImageIcon
You should make sure you're loading the file you think you're loading. Try this: ImageIcon icon = new ImageIcon("path/to/new/icon"); System.out.println(icon.getDescription()); This will be null if the file is not loaded properly. If this is your problem, try using an absolute path (e.g. /home/waTEXmelon/program/blah.jpg on Linux or C:\\Users\\waTEXmelon\\program\\blah.jpg) on Windows. If...
Image not showing in Jtable with renderer
java,swing,jtable,imageicon,tablecellrenderer
The code in a renderer should be very fast and efficient. You should not be doing processing to create the image every time the cell is rendered. Instead you should be storing an ImageIcon in the TableModel. Then you override the getColumnClass(...) method of the TableModel to return Icon.class and...
Where do I get the iOS toolbar icons for up/down arrow?
ios,iphone,objective-c,imageicon
They are not available. They're just a list of icons they have developed for iOS as a showcase. You should look into making them yourself and applying them as a UIButtonTypeCustom. Small drawback is that if the iOS style changes (like iOS6 -> iOS7) you need to manually update your...

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...

Changing Content of JTable Cells Individually
java,jtable,jpanel,cell,imageicon
To change the data in the table you use: table.setValueAt(...); This will update the data in the TableModel. However, adding a JPanel to the table is not the way a table is designed to be used. Typically you add data to the model. Then you use a renderer to display...
JCheckBox with Image
java,swing,jlabel,imageicon,jcheckbox
Without knowing the layout manager, it's difficult to be 100%, but if I was doing this, I might use a GridBagLayout... testate.setLayout(new GridBagLayout()); GridBagConstraints gbc = new GridBagConstraints(); gbc.gridy = 0; gbc.insets = new Insets(4, 4, 4, 4); gbc.anchor = GridBagConstraints.WEST; for (String testata : listaTestate) { gbc.gridx = 0;...
Resize an ImageIcon for an JLabel
java,image,swing,resize,imageicon

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. As the panel is already fairly crowded, I'm not sure the effect would be appealing. Alternatively, implement the IDateEvaluator interface and...
Unable to change button text to icon immediate after click button in java swing
java,swing,jbutton,embedded-resource,imageicon
The GUI system can only do one thing at a time, like most code (except for code that uses threads). Calling your listener is a thing. The GUI system cannot do anything else while your listener is running. Your database operation needs to run on another thread (which you can...
Jbutton with an image as background can't be clicked

Sudoku: Selection image does not appear

How to sort a JTable column that contains icons?
java,swing,jtable,awt,imageicon
The order doesn't matter, just as long as the rows are ordered in the sort. That's simplicity itself. Use table.setAutoCreateRowSorter(true); I already have that in my code It works just fine for me. 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 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...

Your application can't find the ""images/cirkel.png". You have few alternatives: Use an absolute path (like I do in the modified code below).

Image Path in Eclipse using Windows 7 vs Mac OS X
java,eclipse,windows,import,imageicon
You should just be able to do something like the following: picLabel.setIcon(new ImageIcon("/Project/icon.png")); Using the file path like in this example is a better way to retrieve files in any program. This makes it more compatible. So if you were going to deploy this program to other servers/machines you would...

Things to be aware of... ImageIcon can fail silently...annoying I know...this is because...

You should use ImageIO.read to...

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); } ...
Swing ImageIcon causing error and not making image appear
