#1273 — How do you set an Icon in

  To: comp.lang.java.gui
I thought my method would handle this dynamically, but I was way off:

[code]
       /**
         * Handle {@link javax.swing.JButton}
         * @param button {@link javax.swing.JButton}
         */
        private void handleButton(JButton button) {
            try {
                String text = button.getText();
                ImageIcon icon = new ImageIcon(
 
System.getProperty("com.ppowell.applications.globals.rockpaperscissorsglobals.SRC_PATH")
+
 
FileFunctionality.buildFilePath(RockPaperScissorsGlobals.IMAGE_PATH_ARRAY,
true) /* EXCLUDE 1 BACKSLASH */ +
                        File.separator +
                        button.getText().toLowerCase().trim() +
".ico");
                button = new JButton(text, icon);
                Dimension dim = new Dimension(icon.getIconWidth(),
icon.getIconHeight());
                button.setSize(dim);
                button.setPreferredSize(dim);
                button.setMaximumSize(dim);
            } catch (Exception e) {
                e.printStackTrace();
            }
            button.setFocusable(false);
            button.setSelected(false);
            button.addActionListener(RockPaperScissors.this);
            button.setMnemonic(button.getText().charAt(0));
            button.setFont(RockPaperScissorsGlobals.FONT);
        }
[/code]

Instead I see JButtons with no icons, looking dead normal, and worse,
setFocusable(false) is ignored; the JButtons look like they've been
clicked!

What did I do so wrong this time?
Thanx
Phil

After this statement, button is no longer "pointing at" (a reference to) 
the button displayed on your panel. From here on you are manipulating a 
completely separate and invisible button (invisible because it hasn't 
been added to any visible component).

Replace the above line with
   button.setText(text);
   button.setIcon(icon);
(Untested - I've no idea if these are the appropriate methods)

Thanx! Here is the fixed method:

       /**
         * Handle {@link javax.swing.JButton}
         * @param button {@link javax.swing.JButton}
         */
        private void handleButton(JButton button) {
            try {
                ImageIcon icon = IconHandler.createImageIcon(
 
System.getProperty("com.ppowell.applications.globals.rockpaperscissorsglobals.FILE_SRC_PATH")
+
 
FileFunctionality.buildFilePath(RockPaperScissorsGlobals.IMAGE_PATH_ARRAY) /
* EXCLUDE 1 BACKSLASH */ +
                        File.separator +
                        button.getText().toLowerCase().trim() +
                        "." +
 
System.getProperty("com.ppowell.applications.globals.rockpaperscissorsglobals."
+
                        button.getText() + "_ICON_EXT"));
                icon = IconHandler.scaleImageIcon(icon, 16, 16);
                button.setIcon(icon);
                Dimension dim = new Dimension(icon.getIconWidth(),
icon.getIconHeight());
                button.setSize(dim);
                button.setPreferredSize(dim);
                button.setMaximumSize(dim);
            } catch (Exception e) {
                e.printStackTrace();
            }
            button.setFocusable(false);
            button.setSelected(false);
            button.addActionListener(RockPaperScissors.this);
            button.setMnemonic(button.getText().charAt(0));
            button.setFont(RockPaperScissorsGlobals.FONT);
        }


The problem resulted in my attempt to set an .ico file as Icon, and
apparently that is not possible in Java as ".ico" is not recognized as
a legitimate image.  Switching to a JPEG image instead was just fine.
