PyQt5 QSpinBox – 设置样式提示

在本文中，我们将了解如何设置旋转框文本的样式提示。如果所选字体系列不可用，字体匹配算法使用样式提示来查找适当的默认系列。旋转框提供了许多样式提示，例如 AnyStyle、SansSerif、Times 等。
为了做到这一点，我们将 setStyleHint 方法与旋转框的 QFont 对象一起使用。

Syntax : font.setStyleHint(style_hint, style_preference)
Argument : It takes style hint as argument and second argument is optional which is the preference
Return : It returns None 
 

下面是实现

Python3

# 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 style Hint
        font.setStyleHint(QFont.Serif, QFont.PreferOutline)
 
        # reassigning 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())
