How to change the Comment Font Color with C++

Microsoft Excel allows users to add comments to cells to add additional information and highlight data. Developers may need to customize the comment to specify alignment settings, text direction Font Color, etc. Aspose.Cells provides APIs to accomplish the task.

Aspose.Cells provides a Shape.GetTextBody() property to set the font color of the comment. The following sample code demonstrates the use of Shape.GetTextBody() property to set text direction for a comment.

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

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

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

    // Instantiate a new Workbook
    Workbook workbook;

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

    // Add some text in cell A1
    worksheet.GetCells().Get(u"A1").PutValue(u"Here");

    // Add a comment to A1 cell
    int commentIndex = worksheet.GetComments().Add(u"A1");
    Comment comment = worksheet.GetComments().Get(commentIndex);

    // Set its vertical alignment setting
    comment.GetCommentShape().SetTextVerticalAlignment(TextAlignmentType::Center);

    // Set the Comment note
    comment.SetNote(u"This is my Comment Text. This is Test.");

    // Get the comment shape
    Shape shape = comment.GetCommentShape();

    // Set the fill color of the shape to black
    shape.GetFill().GetSolidFill().SetColor(Color::Black());

    // Get the font of the shape
    Font font = shape.GetFont();

    // Set the font color to white
    font.SetColor(Color::White());

    // Create a StyleFlag to apply font color changes
    StyleFlag styleFlag;
    styleFlag.SetFontColor(true);

    // Apply the font color changes to the shape's text
    shape.GetTextBody().Format(0, shape.GetText().GetLength(), font, styleFlag);

    // Save the Excel file
    workbook.Save(outDir + u"outputChangeCommentFontColor.xlsx");

    Aspose::Cells::Cleanup();
}
