QFont::setPointSize() does not take effect

[lovelypp]

In the constructor of the main dialog (inherited from QDialog), I create a QPushButton, the I change its font size using QFont::setPointSize(). But when shown, the font size of QPushButton remains default. It seems that QFont::setPointSize does not take effect or the font size of QPushButton is overrided by something ?
So what' s the chance to change the font size of QPushButton ? How ?
My app is running on Windows Mobile 5, thanks!

How do you exactly use setPointSize()?

[lovelypp]

QFont font = pushButton->font();
font.setPointSize(9); // specificy the font size
pushButton->setFont(font);

Do you use a scalable font?

what's scalable font ?
I just create a QDialog inherited object and show it in main.

thanks!

It's a font that you can scale as opposed to a fixed-size font which comes only in certain sizes.

What is the default font on your system?
