Reusing Style Objects with C++

Reusing style objects can save memory and make a program faster.

To apply some formatting to a large range of cells in a worksheet:

1. Create a style object.
2. Specify the attributes.
3. Apply the style to the cells in the range.

#include <iostream>
#include "Aspose.Cells.h"

using namespace Aspose::Cells;

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

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Output directory path
    U16String outDir(u"..\\Data\\02_OutputDirectory\\");

    // Create workbook object
    Workbook workbook;

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

    // Access cells
    Cell cell1 = worksheet.GetCells().Get(u"A1");
    Cell cell2 = worksheet.GetCells().Get(u"B1");

    // Set the styles of both cells to Times New Roman
    Style styleObject = workbook.CreateStyle();
    styleObject.GetFont().SetColor(Color::Red());
    styleObject.GetFont().SetName(u"Times New Roman");
    cell1.SetStyle(styleObject);
    cell2.SetStyle(styleObject);

    // Put the values inside the cell
    cell1.PutValue(u"Hello World!");
    cell2.PutValue(u"Hello World!!");

    // Save to Pdf without setting PdfSaveOptions.IsFontSubstitutionCharGranularity
    workbook.Save(outDir + u"SampleOutput_out.xlsx");

    Aspose::Cells::Cleanup();
}

Because the Cell.GetStyle/Cell.SetStyle approach uses a lot less memory, and is efficient, the older Cell.Style property which consumed a lot of unnecessary memory, was removed with the release of Aspose.Cells 7.1.0.
