pyqt5 font

PyQt5 comes with a font dialog that you may have seen in a text editor. This is the typical dialog where you can select font, font size, font style and so on. Of course the look and feel depends on the operating system.

To open this dialog import QFontDialog call:

QFontDialog.getFont()

To use it, import QFontDialog from QtWidgets like this:

from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QFontDialog

PyQt5 font dialog

The example below opens a font dialog on a button event, the selected font (font family including size) will be returned as a string.

Font Dialog using PyQt5

Opening a font dialog is as simple as

def openFontDialog(self):
    font, ok = QFontDialog.getFont()
if ok:
    print(font.toString())

A full code example is shown below

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QFontDialog
from PyQt5.QtGui import QIcon
from PyQt5.QtCore import pyqtSlot

class App(QWidget):

    def __init__(self):
        super().__init__()
        self.title = 'PyQt5 font dialog - pythonspot.com'
        self.left = 10
        self.top = 10
        self.width = 320
        self.height = 200
        self.initUI()
    
    def initUI(self):
        self.setWindowTitle(self.title)
        self.setGeometry(self.left, self.top, self.width, self.height)
        
        button = QPushButton('Open PyQt5 Font Dialog', self)
        button.setToolTip('font dialog')
        button.move(50,50)
        button.clicked.connect(self.on_click)
        
        self.show()
    
    @pyqtSlot()
    def on_click(self):
        print('PyQt5 button click')
        openFontDialog(self)
    
    def openFontDialog(self):
        font, ok = QFontDialog.getFont()
    if ok:
        print(font.toString())
    
if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    sys.exit(app.exec_())
