拆分器控件Splitcontainer
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25
int 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!
