PyQt5 QSpinBox – 获取风格策略

在本文中，我们将了解如何获取旋转框文本的样式策略。样式策略告诉字体匹配算法应该使用什么类型的字体来找到合适的默认系列。旋转框提供了许多策略，例如 PreferDefault、PreferBitmap、NoAntialias 等。我们使用setStyleStrategy方法来设置策略。

为了做到这一点，我们使用styleStrategy方法和旋转框的 QFont 对象。

Syntax : font.styleStrategy()

Argument : It takes no argument

Return : It returns QFont strategy object but when printed it shows only its assigned value

编程需要懂一点英语

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 style strategy
        font.setStyleStrategy(QFont.PreferBitmap)
  
        # 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 style strategy
        strategy = font.styleStrategy()
  
        # setting text to the label
        label.setText("Style Strategy : " + str(strategy))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
