示例1: ShouldUseSystemFont
// Returns true when the coerce callback should return the current system metric
private static bool ShouldUseSystemFont(FrameworkElement fe, DependencyProperty dp)
{
bool hasModifiers;
// Return the current system font when (changing the system theme OR creating an element and the default is outdated)
// AND the element is a root AND the element has not had a value set on it by the user
return (SystemResources.SystemResourcesAreChanging || (fe.ReadInternalFlag(InternalFlags.CreatingRoot) && SystemResources.SystemResourcesHaveChanged)) &&
