What are the main differences between these WPF controls?
And when I should use a ToolTip instead of Popup?

推荐答案

ToolTip是一个小的弹出窗口，当用户将鼠标指针悬停在某个元素上时出现. Popup控件提供了一种在单独的窗口中显示内容的方法，该窗口相对于指定的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.如果要自动打开Popup，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.
