PyQt5 QSpinBox – 检查文本是否大写？

在本文中，我们将了解如何设置微调框的文本是否大写，为了设置字体，我们使用以 QFont 对象为参数的 setFont 方法。为了使文本即字体大写，我们必须获取旋转框的 QFont 对象，然后使其大写，然后将其重新分配给旋转框。

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

Syntax : font.capitalization()

Argument : It takes no argument

Return : It returns binary value 0 if capitalization is not on and 1 when it is on

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 capitalize
        font.setCapitalization(True)
  
        # reassigning the font to the spin box
        self.spin.setFont(font)
  
        # creating a label
        label = QLabel(self)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 300, 60)
  
        # getting capitalize status of text
        check = font.capitalization()
  
        # setting text to the label
        label.setText("Capitalize ? : " + str(check))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
