用C++更改切片器属性

可能的使用场景

也许会出现您希望更改切片器的属性的情况，比如位置或行高等。Aspose.Cells为您提供了更新这些属性的选项。

更改切片器属性

请查看以下示例代码。它加载包含表的sample Excel file，然后基于第一列创建切片器，并更改其属性，如行高、宽度、是否可打印、标题等。将工作簿另存为outputChangeSlicerProperties.xlsx。

示例代码

#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;

int main()
{
    Aspose::Cells::Startup();

    // For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

    // Load sample Excel file containing a table.
    U16String sourceDir(u"..\\Data\\01_SourceDirectory\\");
    U16String outputDir(u"..\\Data\\02_OutputDirectory\\");
    Workbook workbook(sourceDir + u"sampleCreateSlicerToExcelTable.xlsx");

    // Access first worksheet.
    Worksheet worksheet = workbook.GetWorksheets().Get(0);

    // Access first table inside the worksheet.
    ListObject table = worksheet.GetListObjects().Get(0);

    // Add slicer
    int32_t idx = worksheet.GetSlicers().Add(table, 0, u"H5");

    Slicer slicer = worksheet.GetSlicers().Get(idx);
    slicer.SetPlacement(PlacementType::FreeFloating);
    slicer.SetRowHeightPixel(50);
    slicer.SetWidthPixel(500);
    slicer.SetTitle(u"Aspose");
    slicer.SetAlternativeText(u"Alternate Text");
    slicer.SetIsPrintable(false);
    slicer.SetIsLocked(false);

    // Refresh the slicer.
    slicer.Refresh();

    // Save the workbook in output XLSX format.
    workbook.Save(outputDir + u"outputChangeSlicerProperties.xlsx", SaveFormat::Xlsx);

    Aspose::Cells::Cleanup();
    return 0;
}
