How get max size text in a QPushButton (Qt embedded linux 4.3.0)

[Gerard]

Hello!

I'm trying to put a 200px text in a QPushButton, in Ubuntu X11 there isn't problem but when i crooscompile to linux embedded text is small. I'm using Qt 4.3.0.

Anyone know how to solve the problem?

I have tryied 2 ways, with next code, but not working :

way 1:

QPushButton temperature;

temperature.setFlat(true);
temperature.setText("300 degrees");
temperature.setMaximumSize(QSize(291, 16777215));
temperature.setStyleSheet("border: 0; background-color: transparent; font: 200px; font-family: Ubuntu");

temperature.setFlat(true);
temperature.setText("300 degrees");
temperature.setMaximumSize(QSize(291, 16777215));
temperature.setStyleSheet("border: 0; background-color: transparent; font: 200px; font-family: Ubuntu");

way 2:

QFont font;
font.setFamily(QString::fromUtf8("Ubuntu"));
font.setPointSize(200);
font.setBold(true);
 
QPushButton temperature;
temperature.setFlat(true);
temperature.setText("300  degrees");
temperature.setMaximumSize(QSize(291, 16777215));
temperature.setFont(font);

QFont font;
font.setFamily(QString::fromUtf8("Ubuntu"));
font.setPointSize(200);
font.setBold(true);

QPushButton temperature;
temperature.setFlat(true);
temperature.setText("300  degrees");
temperature.setMaximumSize(QSize(291, 16777215));
temperature.setFont(font);
