Unset the font of application

[soroush]

Hi

I have a problem with translation process. When translating the application to Persian I changed font to "Tahoma". It should be set to default font when program is translated to English. I'm looking for a way to clear or unset font of application.

Where did you change the font?

@void MainWindow::translateToPersian()
{
this->translateTo("fa");
qApp->setFont(QFont("Tahoma",10));
}@

What does happen if you pass an empty QFont()?
Have you considered setting your application-wide font using an stylesheet an QApplication::setStyleSheet()?

Save the font you were using before then set it back.

QFont() returns the font set with QApplication::setFont.

Nothing happens.
I don't want to deal with fonting things. Just removed Tahoma for Persian interface. But it will be nice if there were some mean for resetting UI fonts :-/

Using style sheets is no option for you? They can be changed easily.

You could query the qApplication->font(); at the start of the program, and save the font that is returned originally. Then you can keep it on hand for when you want to revert back to it.
