vb6的VSFlexGrid控件中的Checked复选框为什么不居中？

在VB6的VSFlexGrid控件中，复选框默认是左对齐的，并且无法直接通过控件属性来居中复选框。可以使用一些技巧来实现复选框的居中显示。

一种方法是使用自定义绘制（Custom Draw）来绘制一个居中的复选框。以下是一个示例代码，演示如何使用自定义绘制将复选框居中显示：

vb
Private Sub VSFlexGrid1_OLEDragCellMouseMove(ByVal ColIndex As Integer, ByVal RowIndex As Integer, _
        ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Single, ByVal Y As Single, ByVal DragState As Integer)
    If ColIndex = 16 Then
        VSFlexGrid1.CustomDraw = flexcdTextBk + flexcdForeColor
        VSFlexGrid1.CellPictureAlignment = flexAlignCenterCenter
    Else
        VSFlexGrid1.CustomDraw = flexcdNone
    End If
End Sub

Private Sub VSFlexGrid1_OLEDragOver(ByVal Data As MSComctlLib.DataObject, _
        ByVal Effect As MSComctlLib.OLEDropEffect, ByVal Button As Integer, ByVal Shift As Integer, _
        ByVal X As Single, ByVal Y As Single, ByVal State As Integer)
    Dim sState As String
   
    ' 设置复选框状态
    If Effect = flexDROPEFFECT_CHECKBOX Then
        If VSFlexGrid1.TextMatrix(VSFlexGrid1.MouseRow, 16) = "" Then
            sState = "0"
        Else
            sState = VSFlexGrid1.TextMatrix(VSFlexGrid1.MouseRow, 16)
        End If
        VSFlexGrid1.TextMatrix(VSFlexGrid1.MouseRow, 16) = IIf(sState = "0", "1", "0")
    End If
End Sub
