Field Detail

cachedLookAndFeel

private static javax.swing.LookAndFeel cachedLookAndFeel

Holds the LookAndFeel that has been used to computed cached values. If the current L&F differs from this cached value, the caches must be cleared.

cachedIsLafAqua

private static java.lang.Boolean cachedIsLafAqua

Holds the cached result of the Aqua l&f check. Is invalidated if a look&feel change has been detected in #ensureValidCache.

private FormUtils()

Method Detail

isLafAqua

public static boolean isLafAqua()

Lazily checks and answers whether the Aqua look&feel is active.

Returns:

true if the current look&feel is Aqua

clearLookAndFeelBasedCaches

public static void clearLookAndFeelBasedCaches()

Clears cached internal Forms state that is based on the Look&Feel, for example dialog base units.

There's typically no need to call this method directly. It'll be invoked automatically, if the L&F has been changed via UIManager.setLookAndFeel(javax.swing.LookAndFeel) and cached data is requested. It's been made public to allow cache invalidation for cases where the L&F is changed temporarily by replacing the UIDefaults, for example in a visual editor.

1.2.1

ensureValidCache
