libreoffice - LibreOffice Calc：访问宏中用户选择的范围

Question

我希望将 MS Excel 电子表格转换为 LibreOffice Calc 电子表格。

Excel 文件包含一个 VBA 宏，它遍历用户选择的一系列单元格，Visual Basic 代码如下所示：

For Each Value In Selection
    ' Manipulate Value
Next Value

其中Selection包含用户手动选择的工作表中的单元格。

所以，我的问题是：如何在 Libre Basic 中重现这一点，访问用户选择的单元格范围？

Answer 1

如果要使用单元格的值

Sub Learn
    Dim myController as Object, myRange as Object
    Dim Tmp as Integer
    Dim i, j

    myController = ThisComponent.getCurrentController()
    myRange = myController.getSelection().getDataArray()

    'additional info that we can use
    print myRange.AbsoluteName
    print myRange.RangeAddress.StartColumn
    print myRange.RangeAddress.StartRow

    Tmp = 0
    For Each i in myRange
        For Each j in i
            Tmp = Tmp + j
        Next j
    Next i
    print Tmp
End Sub

如果要操作单元格的值，请使用二维数组

Sub Learn2
    Dim myController as Object, myRange as Object
    Dim newRange(0, 0)
    Dim Tmp as Integer
    Dim i, j, col, row

    myController = ThisComponent.getCurrentController()
    myRange = myController.getSelection().getDataArray()
    Redim newRange(UBound(myRange, 1), UBound(myRange(0), 1))
    row = 0
    col = 0
    For row = 0 to UBound(myRange, 1)
        For col = 0 to UBound(myRange(0), 1)
            newRange(row, col) = myRange(row)(col) * 2
        Next col
    Next row
    myController.getSelection().setDataArray(newRange)
End Sub
