You can change the text size using html. For that :-

msgBox->setText("<font size="5">" + string + </font>);

msgBox->setText("<font size="5">" + string + </font>);

To copy to clipboard, switch view to plain text mode 

And for the size of messagebox

msgBox->setFixedSize(width,height);

msgBox->setFixedSize(width,height);

To copy to clipboard, switch view to plain text mode

Thank you for your reply.
1- it is correct :

msgBox->setText("<font size=5>" + string + "</font>");

msgBox->setText("<font size=5>" + string + "</font>");

2- messagebox does not change !

StringClass strclass;
    QMessageBox mb(" Win ","<font size=10>" +
    strclass.getStringOne() + "</font>" ,QMessageBox::NoIcon,
                   QMessageBox::Ok | QMessageBox::Default,
                   QMessageBox::NoButton,
                   QMessageBox::NoButton);
 
   QPixmap exportSuccess(":/PIC/award.png");
    mb.setIconPixmap(exportSuccess);
    QPalette palette;
    palette.setBrush(QPalette::Background,QBrush(QImage(":/PIC/award.png")));
    mb.setFixedSize(100,100);
    mb.exec()

StringClass strclass;
    QMessageBox mb(" Win ","<font size=10>" +
    strclass.getStringOne() + "</font>" ,QMessageBox::NoIcon,
                   QMessageBox::Ok | QMessageBox::Default,
                   QMessageBox::NoButton,

    mb.setFixedSize(100,100);
    mb.exec()

Check with this:-

QMessageBox msg(this);
msg.setIconPixmap(QPixmap(":/error.svg"));
msg.setText("No images loaded");
msg.setInformativeText("There are no images in the list. Please create or load a project");
msg.setStandardButtons(QMessageBox::Ok);
msg.setDefaultButton(QMessageBox::Ok);
 
QSpacerItem* horizontalSpacer = new QSpacerItem(500, 0, QSizePolicy::Minimum, QSizePolicy::Expanding);
QGridLayout* layout = (QGridLayout*)msg.layout();
layout->addItem(horizontalSpacer, layout->rowCount(), 0, 1, layout->columnCount());
msg.exec();

QMessageBox msg(this);
msg.setIconPixmap(QPixmap(":/error.svg"));
msg.setText("No images loaded");
msg.setInformativeText("There are no images in the list. Please create or load a project");
msg.setStandardButtons(QMessageBox::Ok);
msg.setDefaultButton(QMessageBox::Ok);
     
QSpacerItem* horizontalSpacer = new QSpacerItem(500, 0, QSizePolicy::Minimum, QSizePolicy::Expanding);
QGridLayout* layout = (QGridLayout*)msg.layout();
layout->addItem(horizontalSpacer, layout->rowCount(), 0, 1, layout->columnCount());
msg.exec();
