QFontDialog

Qt provides a number of other convenient selection dialog boxes similar to the QFileDialog; one such dialog box is the QFontDialog, which allows users to select and configure various aspects of a text font.

Like the other dialog box classes, this is most easily used by calling a static method to display the dialog box and return the user's selection, in this case, the getFont() method.

Let's add a callback method to our MainWindow class to set the editor font:

    def set_font(self):        current = self.textedit.currentFont()        font, accepted = qtw.QFontDialog.getFont(current, self)        if accepted:            self.textedit.setCurrentFont(font)

getFont takes the current font as an argument, which allows it to set the selected font to whatever is current ...
