<![CDATA[Change font sizes for a QFileDialog]]>I am currently opening a QFileDialog using the following static function.

QString fileName = QFileDialog::getOpenFileName(this, tr("Open File"),
        "",
        "",
        0,
        QFileDialog::DontUseNativeDialog);

Is there a way to increase the font size within the dialog that this function call opens?

I have tried to set the stylesheet using the following statement to no effect:

 this->setStyleSheet("QTreeView {font: 16pt \"Arial\";}");

I'm running this on Ubuntu and also tried it on a debian system running LXDE for the window manager.

Did you put the call to set the stylesheet before the filedialog call? I also used a larger font just to be sure it was working:

this->setStyleSheet("QTreeView {font: 26pt \"Arial\";}");
QString fileName = QFileDialog::getOpenFileName(this, tr("Open File"),
        "",
        "",
        0,
        QFileDialog::DontUseNativeDialog);
