PyQt5 QSpinBox – 为向上按钮添加背景颜色

在本文中,我们将了解如何为旋转框的向上按钮设置背景颜色。旋转框基本上有三个组件一个是行编辑另外两个是向上和向下按钮,向上按钮用于增加值。下面是向上按钮的背景颜色的表示。

为此,我们必须更改与旋转框关联的样式表,下面是样式表代码

QSpinBox::up-button
{
background-color : green;
}

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 prefix to spin
        self.spin.setPrefix("Prefix ")
  
        # setting suffix to spin
        self.spin.setSuffix(" Suffix")
  
        # setting style sheet of spin box
        # adding background color to the up-button
        self.spin.setStyleSheet("QSpinBox::up-button"
                                "{"
                                "background-color : green;"
                                "}")
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
