PyQt5 QSpinBox – 确保抛光

在这篇文章中，我们将看到如何确保旋转盒被抛光。抛光旋转框是通过使用QStyle或使用样式表来完成的。抛光是在所有编辑工作结束后完成的，尽管开发者可以通过使用ensurePolished方法来确保抛光的完成。

为了做到这一点，我们使用surePolished方法

语法： spin_box.surePolished()

参数： 它不需要参数

返回： 它返回无。

以下是实现方法

# importing libraries

from PyQt5 import QtCore, QtGui

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")
  
        # ensuring spin box is polished
        self.spin.ensurePolished()
  
        # setting style sheet
        self.spin.setStyleSheet("QSpinBox"
                                "{"
                                "border : 2px solid black;"
                                "background : lightgray;"
                                "}"
                                "QSpinBox::hover"
                                "{"
                                "background : lightblue;"
                                "}")
