PyQt5 Combo Box – 不同的边框大小粗细

在本文中，我们将看到如何创建一个具有不同边框大小的组合框，即不同边的厚度。下面是组合框在不同边框大小下的外观示意图

为此，我们必须更改与组合框关联的样式表代码，下面是样式表代码

QComboBox
{
border : solid black;
border-width : 5px 5px 1px 1px;
}

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 a check-able combo box object
        self.combo_box = QComboBox(self)
  
        # setting geometry of combo box
        self.combo_box.setGeometry(200, 150, 150, 80)
  
        # geek list
        geek_list = ["Sayian", "Super Sayian", "Super Sayian 2", "Super Sayian B"]
  
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
  
        # setting style sheet to the combo box
        # setting background with different thickness 
        self.combo_box.setStyleSheet("QComboBox"
                                     "{"
                                     "border : solid black;"
                                     "border-width : 6px 5px 1px 1px;"
                                     "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
window.show()
  
# start the app
sys.exit(App.exec())

输出 ：
