Java Get Default UI Colors

How could I find out the default selection color in a JList for example?

Whe开发者_高级运维re are these colors are stored?

For Swing components you can get and set the default colors in the application wide UIDefaults provided by the UIManager:

UIDefaults defaults = javax.swing.UIManager.getDefaults();
defaults.getColor("List.selectionBackground");
defaults.getColor("List.selectionForeground");

---

UIMManager Defaults lists all the defaults in a nicely formatted GUI.

---

JList.getSelectionForeground();
JList.getSelectionBackground();

for that particular box.

Usually they will be read from SystemColor.textHighlight and SystemColor.textHighlightText at the time the UI is created.
