使用SplitContainer1控件不就行了，SplitContainer1控件的Fixedpanel属性设置为Panel1\x0d\x0aSplitContainer1的Panel2里面再放置一个SplitContainer2\x0d\x0aSplitContainer2控件的Fixedpanel属性设置为Panel2\x0d\x0a二个SplitContainer设置为水平折为器方向\x0d\x0a至于播放器控件就放在SplitContainer2控件Panel1里面\x0d\x0a播放器控件DOCK设置为FILL\x0d\x0a\x0d\x0a这样不管放大缩小界面，播放器控件总是自适应窗体大小而菜单按钮总是在最边缘
