拆分器控件Splitcontainer ,是一个含有Splitter拆分条的容器,它包含两个面板容器Panel1,Panel2,可以移动拆分条,对面板大小进行控制!
控件学习示例程序!
属性介绍;
//拆分条的是否启用禁用bool IsSplitterFixed{get;set;} bool类型，true:不能调节拆分条; false :能够使用拆分条.决定是否可以通过键盘或鼠标来移动拆分器。
//拆分器的方向；垂直和水平方向上拆分控件,上下和左右两块面板Orientation Orientation{get;set;}Orientation是枚举;包含两个值;水平与垂直; Vertical ; Horizontal ;
//获取拆分条(器)的大小Rectangle SplitterRectangle{get;} 取得拆分条的矩形表示形式；new Rectangle(X,Y width,height)拆分器就是指拆分条,坐标点，宽高拆分条，是一个矩形表示的！该属性的变化，与Orientation属性相关！垂直，水平显示状态，拆分条的位置大小当然不同！
//指定拆分器面板之一保持不变调节拆分器，使用panel1或panel2面板不会改变大小；FixedPanel FixedPanel{get;set;}FixedPanel枚举： 有三个值；None(默认值）, Panel1 ,Panel2;确定调整SplitterContainer控件后，哪个面板将保持不变！调整拆器容器大小时，可以保持哪个面板不变时，才设置此属性，如果容器不会改变，也不用设置此属性！
//设置拆分器离容器的初始大小，拆分条左或上边缘离容器的初始宽度。int SplitterDistance{get;set;}像素为单位，默认值为40 ,在移动拆分器时，这个值是变化的，计算左边缘或上边缘的距离！拆分器的初始距离.
//设置拖动拆分条（器）移动的增量大小，也就是拖移的速度！同样的拖动，移动的宽度可不相同。int SplitterIncrement{get;set;}获取设置拆分条移动的增量,默认值为1;测试SplitterIncrement属性值的大小，可以通接受键盘上下键的，调节拆分器，IsSplitterFixed必须为true
//设置拆分条的宽度int SplitterWidth{get;set;}默认值为4 ，通过设置可以更改此值，使拆分条的宽度变粗！
// 获取设置拆分器与panel1的左边缘，或上边缘的距离固定大小 ;与边缘的默认大小为25int Panel1MinSize{get;set;}int Panel2MinSize{get;set;}此属性作用比较大，可控制拆分器的活动范围大小，也就是左右面板中固定的大小面积，拆分器不能进行拖放进入的区域。 把该属性设置为0;表示拆分器可以到过缘。
//设置拆分器的Panel1 Panel2折叠或展开；bool Panel1Collapsed{get;set;}bool Panel2Collapsed{get;set;}
注意：Panel1Collapsed属性，true为拆叠，false展开为默认值，在拆叠状态下，不能设置SplitterDistance,SplitterWidth属性，这时的拆分器处了隐藏关闭状态，必须在展开时才能设置这些属性！
//Pane1 与Pane2属性 拆分器的两个面板容器SplitterPanel Panel1{get}SplitterPanel Panel2{get;}SplitterPanel:Panel类型
此属性设置如果与SplitterDistance属性冲突，拆分条的初始位置会以此属性为准进行定位！
事件介绍：1：SplitterMoving事件拆分器移动时发生；拆分条移动过程中发生！委托类型；SplitterCancelEventHandler数据类型为：SplitterCancelEventArgs :CancelEventArgs 数据成员为：SplitX,SplitY,MouseCursorX,MouseCursorY,表示在工作区，鼠标指针，拆分条的坐 标值。
SplitX SplitY X坐标点指的是拆分器与容器距离，垂直Y为0 MouseCursorX MouseCursorY 表示鼠标指针在工作的位置点坐标
2: SplitterMoved事件
拆分器移动后发生；委托类型；SplitterEventHandler数据类型；SplitterEventArgs :EventArgs 数据成员；SplitX,SplitY,X,Y 表示在工作区，鼠标指针，拆分条的坐标值，这都是移动后的位置值！
Moving事件是指，鼠标按住拆分器，不放，进行移动时，发生，只要拆分器移动就会发生，不移则事件不会发生！Moved事件是指，移动拆分器之后，释放鼠标时，发生的！它是Moving事件之后发生！
小结：
控件的Dock属性如果设置成Fill,窗体的单击事件，不会被触发；因为控件遮挡住了！
