推荐答案

ToolTip 是一个小弹出窗口，当用户将鼠标指针悬停在元素上时会出现；Popup 控件提供了一种在单独窗口中显示内容的方法，该窗口相对于指定元素或屏幕坐标浮动在当前应用程序窗口上.

A ToolTip is a small pop-up window that appears when a user pauses the mouse pointer over an element; the Popup control provides a way to display content in a separate window that floats over the current application window relative to a designated element or screen coordinate.

当鼠标指针移到其父对象上时，Popup 不会自动打开.如果您希望 Popup 自动打开，请使用 ToolTip 或 ToolTipService 类.

A Popup does not automatically open when the mouse pointer moves over its parent object. If you want a Popup to automatically open, use the ToolTip or ToolTipService class.
