How to set jLabel's ImageIcon from File instance's absolutePath
Question
I want to add a photo from a chosen image File to a jPanel but, the following code doesn't seem to work :
private void browsePhotoButtonActionPerformed(java.awt.event.ActionEvent evt) {
JFileChooser fileChooser = new JFileChooser();
String[] fileSuffixes = ImageIO.getReaderFileSuffixes();
for(String fileSuffix:fileSuffixes){
FileFilter filter = new FileNameExtensionFilter(fileSuffix + " files", fileSuffix);
fileChooser.addChoosableFileFilter(filter);
}
int selection = fileChooser.showOpenDialog(EmployeeInternalFrame.this);
if(selection == JFileChooser.APPROVE_OPTION){
File fileBeingOpened = fileChooser.getSelectedFile();
setPhotoFile(fileBeingOpened);
setImageURL(getPhotoFile().getAbsolutePath());
photoPanel.removeAll();
Icon icon = new ImageIcon(getImageURL());
JLabel label = new JLabel(icon, SwingConstants.LEFT);
photoPanel.add(label);
photoPanel.repaint();
}
}
Which part am I missing ? Thank you for all of your help.

The documentation of ImageIcon(String filename) states that:
Creates an ImageIcon from the specified file. The image will be preloaded by using MediaTracker to monitor the loading state of the image. The specified String can be a file name or a file path. When specifying a path, use the Internet-standard forward-slash ("/") as a separator. (The string is converted to an URL, so the forward-slash works on all systems.) For example, specify:
new ImageIcon("images/myImage.gif")The description is initialized to the filename string.
So, what I think your problem is with the path that you have given as parameters which has \\ in the path.

I "think" the problem is with the use of GroupLayout, it's generally a pain in the ... Code ... Personally, I'd use a different layout, even with the form editor and add a place holder label for the phot, which you can use to set the icon – MadProgrammer yesterday
I changed the panel's layout into Card Layout, and it's fine now, thank you everyone :)
