是不是想象东方快车一样?<br>说一个简单方法。<br>1、Form设置为bsToolWindow或干脆bsNone;<br>2、加一个定时器,100ms;<br>3、在定时器的触发事件中判断鼠标的位置,用GetCursorPos(@pos);<br>BOOL GetCursorPos(<br> LPPOINT lpPoint // address of structure for cursor position <br> <br> <br>Parameters<br>lpPoint<br>Points to a POINT structure that receives the screen coordinates of the cursor. <br>判断鼠标的位置,再让Form显示还是缩小或隐藏.<br><br>(今天心情不太好,具体实现你就看着办吧)<br>
