例子

VBA：

Sub Example_TextAlignmentPoint()
    ' This example creates a text object in model space.
    ' It then changes the TextAlignmentPoint and HorizontalAlignment
    ' properties of the text object.

    Dim textObj As AcadText
    Dim textString As String
    Dim insertionPoint(0 To 2) As Double
    Dim height As Double
    
    ' Define the text object
    textString = "Hello, World."
    insertionPoint(0) = 3: insertionPoint(1) = 3: insertionPoint(2) = 0
    height = 0.5
    
    ' Create the text object in model space
    Set textObj = ThisDrawing.ModelSpace.AddText(textString, insertionPoint, height)
    ZoomAll
    MsgBox "The TextAlignmentPoint is set to the default " & _
           textObj.TextAlignmentPoint(0) & ", " & _
           textObj.TextAlignmentPoint(1) & ", " & _
           textObj.TextAlignmentPoint(2), vbInformation, _
           "TextAlignmentPoint Example"
    
    ' Change the value of the HorizontalAlignment and
    ' TextAlignmentPoint properties.
    ' Note that the HorizontalAlignment property must be changed first,
    ' and to a value that requires the TextAlignmentPoint, before the
    ' TextAlignmentPoint property will allow a value to be set.
    Dim alignmentPoint(0 To 2) As Double
    alignmentPoint(0) = 5: alignmentPoint(1) = 3: alignmentPoint(2) = 0
    textObj.HorizontalAlignment = acHorizontalAlignmentFit
    textObj.TextAlignmentPoint = alignmentPoint
    ZoomAll
    MsgBox "The TextAlignmentPoint is set to " & _
           textObj.TextAlignmentPoint(0) & ", " & _
           textObj.TextAlignmentPoint(1) & ", " & _
           textObj.TextAlignmentPoint(2) & vbCrLf & _
           "The HorizontalAlignment is set to acHorizontalAlignmentFit", _
           vbInformation, "TextAlignmentPoint Example"
    
End Sub
