I'm having some trouble customizing a dynamic combobox. my current style is as follows

QCheckBox *checkbox = new QCheckBox(QString(query.value(2).toString()),this) ;
checkbox->setStyleSheet("font: MS Shell Dlg 2; font-size: 40px; color: white;");
checkbox->setCheckable(false);
checkbox->setIconSize(QSize(60,60));
checkbox->setIcon(QIcon(":/images/Circles1.png"));

Now the issue is, i get a checkmark box next to the icon. but I want the Icon "instead of the checkmark box". How do I do that. I've seen examples of indicators. but they only seem to work if you manually set the stylesheet in qt designer
