示例1: canDirectlyAccessGraphics

// TODO: what about popup windows / tooltips???
// TODO: some of the queries could be cached instead of polling,
// for example isShowing(), isOpaque(), getParent() etc.
////// // Shouldn't access graphics - no buffering would cause flickering
////// if (bufferType == BUFFER_NONE) return false;
// Cannot access graphics - there are some child components
if (getComponentCount() != 0) return false;
// Cannot access graphics - component doesn't fully control its area
if (!isOpaque()) return false;
// Cannot access graphics - not in Swing tree
if (!(getParent() instanceof JComponent)) return false;
// Cannot access graphics - component not showing, doesn't make sense
if (!isShowing()) return false;
// Cannot access graphics - component area is not up-to-date
