推荐答案
没有Windows消息/事件指示鼠标进入"或鼠标离开".但是，可以通过为控件处理"MouseMove"消息并捕获鼠标输入以检查该点是否在控件区域内来实现此目的.如果该点不在控制区域内，则释放捕获.
There is no windows message/event that indicates 'mouse enter' or 'mouse leave'.However this can be achieved by handling the 'MouseMove' message for your control and capturing the mouse input to check if the point is inside the control area. Release the capture if the point is out of the control area.
