Split 方法（ActiveX）

将视口拆分为给定的视图数。

支持的平台：仅限 Windows

签名

VBA：

object.Split NumWins

对象

类型：视口

此方法应用到的对象。

NumWins的

访问：仅输入

类型：枚举AcViewportSplitType

acViewport2Horizontal
acViewport2Vertical
acViewport3Above
acViewport3Below
acViewport3Horizontal
acViewport3Left
acViewport3Right
acViewport3Vertical
acViewport4

返回值（RetVal）

无返回值。

言论

尽管已调用该方法，但在使用该属性使视区处于活动状态之前，不会显示更改。即使视口在调用之前处于活动状态，这也是必需的。SplitActiveViewportSplit

视口不必处于活动状态即可使此方法正常工作，但是，必须将其重置为活动状态才能查看此方法的结果。

例子

VBA：

Sub Example_Split()
    ' This example creates a new viewport and makes it active.
    ' Then it splits the viewport into four windows.
    ' It then takes one of the four windows, and splits that
    ' window horizontally in half.
    Dim newViewport As AcadViewport
       
    ' Create a new viewport and make it active
    Set newViewport = ThisDrawing.Viewports.Add("TESTVIEWPORT")
    ThisDrawing.ActiveViewport = newViewport
    
    ' Split the viewport in four windows
    newViewport.Split acViewport4
    
    ' Make the newly split viewport active
    ThisDrawing.ActiveViewport = newViewport
    
    ' Note that current drawing layout will show four windows.
    ' However, only one of the windows will be active.
    ' The following code sets the lower-left corner window
    ' to be the active window and then splits that
    ' window into two horizontal windows.
    Dim entry
    For Each entry In ThisDrawing.Viewports
        If entry.name = "TESTVIEWPORT" Then
            Dim lowerLeft
            lowerLeft = entry.LowerLeftCorner
            If lowerLeft(0) = 0 And lowerLeft(1) = 0 Then
                Set newViewport = entry
                Exit For
            End If
        End If
    Next
    newViewport.Split acViewport2Horizontal
    ThisDrawing.ActiveViewport = newViewport
End Sub
