PyQt5 QSpinBox – 设置提示首选项

在本文中，我们将了解如何获得旋转框字体的提示偏好，可以将不同级别的提示应用于字形以提高像素密度可能保证的显示器的易读性。我们可以借助setHintingPreference方法设置提示首选项。

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

Syntax : font.hintingPreference()

Argument : It takes no argument

Return : It returns preference object but when we print it, it shows the respective value of the preference.

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()
  
        # setting hinting preference
        font.setHintingPreference(QFont.PreferFullHinting)
  
        # reassigning this 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 hitting preference
        check = font.hintingPreference()
  
        # setting text to the label
        label.setText("Hitting Preference  : " + 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 ：
