示例1: UpdateStyleCache
// ===========================================================================
// These methods are invoked when a Style/Template cache needs to be updated
// ===========================================================================
#region UpdateCache
//
// This method
// 1. Updates the style cache for the given fe/fce
//
internal static void UpdateStyleCache(
FrameworkElement fe,
FrameworkContentElement fce,
Style oldStyle,
Style newStyle,
ref Style styleCache)

// We have a new style. Make sure it's targeting the right
// type, and then seal it.

}
newStyle.CheckTargetType(d);
newStyle.Seal();
}
styleCache = newStyle;
// Do style property invalidations. Note that some of the invalidations may be callouts
// that could turn around and query the style property on this node. Hence it is essential
// to update the style cache before we do this operation.
StyleHelper.DoStyleInvalidations(fe, fce, oldStyle, newStyle);
// Now look for triggers that might want their EnterActions or ExitActions
// to run immediately.
StyleHelper.ExecuteOnApplyEnterExitActions(fe, fce, newStyle, StyleDataField);
}示例2: UpdateThemeStyleCache
//
// This method
// 1. Updates the theme style cache for the given fe/fce
//
internal static void UpdateThemeStyleCache(

Style newThemeStyle,
ref Style themeStyleCache)

}
