推荐答案
@David是正确的,主机平台拥有 JFrame
装饰,但你可以利用 JInternalFrame
图标,通常概括了平台的图标。例如,
@David is correct that the host platform owns the JFrame
decorations, but you may be able to leverage the JInternalFrame
icons, which typically recapitulate those of the platform. For example,
private static final Icon ICON = (Icon) UIManager.get("InternalFrame.closeIcon");
枚举其他装饰默认值这里。
