How to set the font size of my QPushButton?

[Eduardo12l]

This is my QPushButton

QPushButton *bu = new QPushButton(this);
bu->setText(nombre);
if(nombre.length() > 12){
             ????????????????? // I want to set here the font size  of "nombre"
}
bu->setParent(this);
bu->setMaximumWidth(121);
bu->setMinimumWidth(121);
bu->move(140+120*val,(100+40*(DefI[i]-5)));
bu->setMaximumHeight(41*(DefF[i]-DefI[i]));
bu->setMinimumHeight(41*(DefF[i]-DefI[i])); 
bu->setStyleSheet("background-color: QLinearGradient(spread:pad x1: 0, y1: 0, x2: 0, y2: 1, stop: 0.0" + DefColores[i][0] + ",  stop: 0.4" + DefColores[i][1] + ", stop: 1.0"+ DefColores[i][2]+");"  
                           "color: white; "
                           "border-style: solid;"
                           "border-style: solid;"
                           "border-radius: 7;"
                           "padding: 3px;"
                           "padding-left: 5px;"
                           "padding-right: 5px;"
                           "border-color: #339;"
                           "border-width: 1px;"
                           "font:Bold;"
                           "font-family:Georgia");

@Eduardo12l
since you're doing your font stuff in the stylesheet, size is a valid QSS property therefore:

font-size:20px;

Hi @Eduardo12l

I advise to use stylesheet as @J-Hilk told you

bu->setStyleSheet("font-size: 20px;");

Or if you are not a fan of qt stylesheet you can extract font of your button, and then change it :

QFont font = bu->font();
font.setPointSize(20);
bu->setFont(font);

Hope this can help you !
