How to get the font name as readable text

EarlyBird

After setting the font to a label, I would like to print it for info.
The setFont method works, but when printing the font info it shows:
Code:

print(self.label.fontInfo, self.fontComboBox.currentFont)

<built-in method fontInfo of QLabel object at 0x10dd91c60>

How do I show the font name as text?

        self.ui = uic.loadUi('Test_font_v1.0.ui', self)
        base_dir = os.path.dirname(__file__)
        print("Current folder: ",os.getcwd())
        print("Path relative to: ", base_dir)
        self.label_2.setScaledContents(True)
        self.fontComboBox.currentFontChanged.connect(self.font_to_label)
        self.comboBox.currentTextChanged.connect(self.list_changed)

    def list_changed(self, s):
        self.label.setText(s)

    def font_to_label(self):
        #self.label.font = self.fontComboBox.currentFont()
        self.label.setFont(self.fontComboBox.currentFont())
        self.comboBox.setFont(self.fontComboBox.currentFont())
        print(self.label.fontInfo, self.fontComboBox.currentFont)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec())

@EarlyBird
I assume this is code copied from an actual working example? Because you use:

QFont.family(font)
QFontInfo.family(font)

If you look at these methods in PySide documentation you find QFont.family() and QFontInfo.family(). These are member methods of QFont/QFontInfo, and family() does not accept a parameter. You can call them on a QFont or QFontInfo instance. I can guess that Python may allow you to invoke it via the class method with a parameter of a QFont instance as a parameter, but this strikes me as "unusual" if you choose to call your instance methods in this way.

I would suggest the "standard" way to call it would be

print(self.label.font().family())
// or if you really want
print(self.label.fontInfo().family())

[I should not have written familyName() in my previous reply.]

Separately, if you are interested there is also

print(self.label.font().toString())

which would return a whole list of attributes of the font.

@EarlyBird said in How to get the font name as readable text:

How do I show the font name as text?

I think the closest to a name for the font is the famliyName(). Or there is substitutes() if it can't be found. Don't know if it tells you if it has to use one.

Hi,

As the error message suggests: you are trying to print the function themselves rather than what they return. You are missing parenthesis at the end of both calls.

Thank you JonB and SGaist,

found it thanks to your tips:

        font = self.label.font()
        print(QFont.family(font))

The same works with QFontInfo:

        font = self.label.fontInfo()
        print(QFontInfo.family(font))

Then it gives out the font as text (str).

This works also:

print(QFont.family(self.label.font()))

Instead of print you can put in a str variable:

        font = QFont.family(self.label.font())
        print(type(font))

Returns
<class 'str'>
