List of Java Swing UI properties? [closed]

Question

There seem to be a ton of UI properties that can be set with

 UIManager.put("key", value);

Is there a list somewhere of all keys that can be set?

Answer 1

It depends on the Java implementation. Here is the simple code that you can run to see all available properties and their current values.

public static void main(String[] args) {
            UIDefaults defaults = UIManager.getDefaults();
            System.out.println(defaults.size()+ " properties defined !");
            String[ ] colName = {"Key", "Value"};
            String[ ][ ] rowData = new String[ defaults.size() ][ 2 ];
            int i = 0;
            for(Enumeration e = defaults.keys(); e.hasMoreElements(); i++){
                Object key = e.nextElement();
                rowData[ i ] [ 0 ] = key.toString();
                rowData[ i ] [ 1 ] = ""+defaults.get(key);
                System.out.println(rowData[i][0]+" ,, "+rowData[i][1]);
            }
            JFrame f = new JFrame("UIManager properties default values");
            JTable t = new JTable(rowData, colName);
            f.setContentPane(new JScrollPane(t));
            //f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            f.pack();
            f.setVisible(true);
        }

I found the official list of resource keys used in the Nimbus Look and feel:

http://docs.oracle.com/javase/tutorial/uiswing/lookandfeel/_nimbusDefaults.html

And the official component properties:

http://docs.oracle.com/javase/8/docs/api/javax/swing/plaf/synth/doc-files/componentProperties.html

And here is another exhausting list (not Nimbus related). This is the source.

Don't you think it's a link only answer? – Autocephalous

Yes, it is, but the question is very simple which seeks for a list of keys, and the linked web page contains the list. I would gladly add other content to my answer but I don't feel anything more justified and didn't want to spam unnecessary text. – Libertine

Or do you think the list could be included in my answer (obviously containing the source)? – Libertine

It could be included or it would be best if there is any official blog/documentation link for the same. Isn't there any? – Autocephalous

Found an official list. Also included the list citing the source. Thanks. – Libertine

Now I guess answer looks complete and perfect :D – Autocephalous

Answer 3

For what it's worth, you can find a fancier version of this where all the properties are displayed in a GUI with each component on a separate tab in a tabbed pane. You can also change the LAF. Check out UIManager Defaults.

Moorhead

Thanks! I'd stumbled on this tool once before & this was the link that led me to it again. Very useful. (I'm currentlty trying to bash Java 8 into reasonable HiDPI support - fonts, icons and spacing. I hope this isn't a fool's errand before Java 9 adds official support...) – Sorci

Answer 4

The code posted before just gets the properties set by the current look&feel which is the metal l&f by default.

It lists a total of 636 defined properties on my system (WinXP with Java 1.6.0_17) with less defined on Windows L&F and Motif L&F. I found another list on the internet (http://www.java2s.com/Tutorial/Java/0240__Swing/ListingUIDefaultProperties.htm) where 795 are found.

So I think the question still remains: Which properties are there? Obviously, even the Metal L&F doesn't set them all (or the code resulting in 795 is wrong).

I am puzzled by the fact there doesn't seem to exist an official list by sun, which would be what I really am looking for (as well as the OP if I got the question right).

I have the same problem! – Cellulous

@Cellulous Check my answer to my own question here, there you'll find an explanation of why the problem really isn't one. Basically, you can set what you want, but check the properties of the L&F you are using for what's there, because these can be expected to be the only properties that are used by the l&f. – Honourable

Answer 5

I had a similar issue where few UI elements were displaying in tiny fonts. I have printed all the keys using below code and updated the specific elements

for (Iterator i = UIManager.getLookAndFeelDefaults().keySet().iterator(); i.hasNext();) {
            String key = new String();
            Object tmpKey = i.next();              
            if (tmpKey instanceof StringBuffer) {
                StringBuffer s = (StringBuffer) tmpKey;
                key = s.toString();                  
            } else {
                key = (String) tmpKey;
            }
            //Print all the keys available in UI manager
            System.out.println("Key:  " + key);
            if (key.endsWith("TabbedPane.font")) {                
                Font font = UIManager.getFont(key);
                Font biggerFont = font.deriveFont(2* font.getSize2D());
                // change ui default to bigger font
                UIManager.put(key, biggerFont);
            }else if(key.endsWith("Tree.rowHeight")){
                int rowHeight = UIManager.getInt(key);
                int bigRowHeight = 2*rowHeight;
                UIManager.put(key, bigRowHeight);
            }
        }
