initSystemColorDefaults	back to summary
protected void initSystemColorDefaults(UIDefaults table) Overrides javax.swing.plaf.basic.BasicLookAndFeel.initSystemColorDefaults. Doc from javax.swing.plaf.basic.BasicLookAndFeel.initSystemColorDefaults. Populates `table` with system colors. This creates an array of `name-color` pairs and invokes `loadSystemColors`. The name is a `String` that corresponds to the name of one of the static `SystemColor` fields in the `SystemColor` class. A name-color pair is created for every such `SystemColor` field. The `color` corresponds to a hex `String` as understood by `Color.decode`. For example, one of the `name-color` pairs is `"desktop"-"#005C5C"`. This corresponds to the `SystemColor` field `desktop`, with a color value of `new Color(0x005C5C)`. The following shows two of the `name-color` pairs: String[] nameColorPairs = new String[] { "desktop", "#005C5C", "activeCaption", "#000080" }; loadSystemColors(table, nameColorPairs, isNativeLookAndFeel()); As previously stated, this invokes `loadSystemColors` with the supplied `table` and `name-color` pair array. The last argument to `loadSystemColors` indicates whether the value of the field in `SystemColor` should be used. This method passes the value of `isNativeLookAndFeel()` as the last argument to `loadSystemColors`. Annotations @Override

The color corresponds to a hex String as understood by Color.decode. For example, one of the name-color pairs is "desktop"-"#005C5C". This corresponds to the SystemColor field desktop, with a color value of new Color(0x005C5C).

As previously stated, this invokes loadSystemColors with the supplied table and name-color pair array. The last argument to loadSystemColors indicates whether the value of the field in SystemColor should be used. This method passes the value of isNativeLookAndFeel() as the last argument to loadSystemColors.

Gnome layout style. From: http://developer.gnome.org/projects/gup/hig/2.0/design-window.html#window-layout-spacing You'll notice this doesn't do the radiobutton/checkbox border adjustments that windows/metal do. This is because gtk doesn't provide margins/insets for checkbox/radiobuttons.
