'在(10,10)模拟鼠标左键按下
控件是可以显示在里面的,你只要加个label,把label的属性设为visualble=fause就行。设置鼠标经过头像的mouseHover和mouseLeave事件,当mouseHover时label的属性visualble=true,当mouseLeave时label的属性visualble=fause即可。窗体的鼠标事件可以设置控件的cursor属性,里面可以选择许多种鼠标图形。 只要是正常的Form都可以改变窗体大小,但是无边框的窗体只能用函数改变或者设置属性,在debug后是不能改变的。拖动窗体需要在窗体的load时间里面写入当鼠标单击不放时的事件即可,不难。
