PyQt5 – 为组合框中的所有项目设置字体

在这篇文章中，我们将看到如何改变列表中所有项目的大小和字体。为了做到这一点，我们将使用setFont方法，该方法以QFont对象为参数，与复选框对象一起使用将改变列表中所有项的字体。

语法： check_box.setFont(font)

参数： 它接受字体对象作为参数

返回：无

以下是实现方法

# importing libraries

class Window(QMainWindow):

        # setting title
        self.setWindowTitle("Python ")
  
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
  
        # calling method

        # showing all the widgets
        self.show()

        # creating a combo box widget
        self.combo_box = QComboBox(self)
  
        # setting geometry of combo box
        self.combo_box.setGeometry(200, 150, 150, 30)
  
        # geek list
        geek_list = ["Sayian", "Super Sayian"]
  
        # making it editable
        self.combo_box.setEditable(True)
  
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
  
        # font
        font = QFont('Arial', 10)
  
        # adding action to combo box
        self.combo_box.setFont(font)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
