Which default icons are available

[JiJi]

I try to create a simple JButton with an arrow icon that shall look the same as the arrow buttons in for instance the JScrollPane and JComboBox.

I've found something like UIManager.getIcon( "Some icon string" ) but which icon strings are available to me? Is this the right way to copy the look of another component?

This is not documented anywhere. In general, there is no reliable API to get internal icons, especially not in a PLAF-independent way. You can get the UIDefaults via the UIManager and print all the defaults (it is a Map). There is e.g. a small tool called ShowUIDefaults.java out there doing this with a GUI.

This list will contain among other things the icon key/value pairs, so you will see which ones are available for the current PLAF. But another PLAF or another VM implementation might provide a completely different set of icons, or no icons at all.

If you want to deal with Metal only, you can use javax.swing.plaf.metal.MetalIconFactory to get Metal-Related icons. This is at least a public API, although not a really good one. You could also snoop round in the javax.swing.plaf.basic.BasicIconFactory for some more icons.

Ok, thanks. I'll check that out.

This page (http://forums.sun.com/thread.jspa?threadID=5338038) has some code sample that shows the default values for a given theme, thus teling which icon strings it supports.

For the Nimbus look and feel, I got this info:
Tree.collapsedIcon
FileChooser.directoryIcon
FileChooser.detailsViewIcon
OptionPane.questionIcon
FileChooser.newFolderIcon
FileView.floppyDriveIcon
Tree.openIcon
Tree.expandedIcon
OptionPane.informationIcon
Tree.closedIcon
Tree.leafIcon
FileChooser.upFolderIcon
OptionPane.errorIcon
ToolBar.handleIcon
FileChooser.floppyDriveIcon
FileChooser.fileIcon
RadioButton.icon
FileView.fileIcon

Haven't tested all values though.
