PyQt5 QSpinBox – 为向下箭头添加边框

PyQt5 QSpinBox – 为向下箭头添加边框

在这篇文章中,我们将看到如何为向下箭头添加边框,我们知道在旋转盒中存在两个向上和向下的按钮,向下箭头是向下按钮的内部部分。向下箭头是向下按钮的子集,向下按钮是自旋盒的子集。默认情况下,向下箭头是没有边框的,下面是向下箭头的边框的表现。

为了做到这一点,我们必须改变与旋转框相关的样式表代码,下面是样式表代码

QSpinBox::down-arrow
{
border : 4px solid green;
}

以下是实施情况

# 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, 60)
  
        # setting prefix to spin
        self.spin.setPrefix("Prefix ")
  
        # setting suffix to spin
        self.spin.setSuffix(" Suffix")
  
        # setting style sheet to the spin box
        # adding border to the down button
        # adding border to the down arrow
        self.spin.setStyleSheet("QSpinBox::down-button"
                                "{"
                                "border : 3px solid pink;"
                                "}"
                                "QSpinBox::down-arrow"
                                "{"
                                "border : 4px solid green;"
                                "}")
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
