推荐答案

处理MouseEnter和MouseLeave事件.

编辑---------------

处理MouseEnter事件后，请捕获鼠标，以便您可以在控件内跟踪其移动.当到达特定点时，请执行某些操作.处理MouseLeave事件后，停止捕获鼠标.

Handle the MouseEnter and MouseLeave events.

EDIT ---------------

When the MouseEnter event is handled, capture the mouse so you can track it''s movement within the control. When it gets to a specific point, do something. When the MouseLeave event is handled, stop capturing the mouse.
