PyQt5 QSpinBox – 获取样式提示

在本文中，我们将了解如何获得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，如 AnyStyle、SansSerif、Times 等。我们可以借助setStyleHint方法为旋转框设置样式提示。

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

Syntax : font.styleHint()

Argument : It takes no argument

Return : It returns QFont’s Style hint object but when get printed it shows the value associated with it

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 hint
        font.setStyleHint(QFont.Serif, QFont.PreferOutline)
  
        # 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 hint
        style_hint = font.styleHint()
  
        # setting text to the label
        label.setText("Style Hint value: " + str(style_hint))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
