PyQt5 QSpinBox - 使文本斜体

在本文中，我们将看到如何将旋转框的文本设置为斜体，以便使用以QFont对象为参数的setFont方法设置字体。为了使文本即字体斜体，我们必须获取旋转框的 QFont 对象，然后将其设置为斜体，然后将其重新分配给旋转框。

In order to do this we use setItalic method with the QFont object of the spin box

Syntax : font.setItalic(True)

Argument : It takes bool as argument

Return : It returns None

下面是实现

# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys
  
  
class Window(QMainWindow):
  
    def __init__(self):
        super().__init__()
  
        # setting title
        self.setWindowTitle("Python ")
  
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
        # method for widgets
    def UiComponents(self):
        # creating spin box
        self.spin = QSpinBox(self)
  
        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)
  
        # setting range to the spin box
        self.spin.setRange(0, 999999)
  
        # setting prefix to spin
        self.spin.setPrefix("Prefix ")
  
        # setting suffix to spin
        self.spin.setSuffix(" Suffix")
  
        # getting font of the spin box
        font = self.spin.font()
  
        # making font italic
        font.setItalic(True)
  
        # setting back this font to the spin box
        self.spin.setFont(font)
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
