PyQt5组合框 具有不同边框大小（厚度）的列表视图部分

在这篇文章中，我们将看到如何为组合框的列表视图的不同侧面创建不同的边框大小，即厚度。列表视图基本上是组合框的一部分，它显示了所有的项目，下面是组合框在不同边框尺寸下的样子

为了做到这一点，我们必须改变与组合框相关的样式表代码。下面是样式表的代码

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

下面是实现方法

# 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
        # adding different thickness border to list view
        self.combo_box.setStyleSheet("QListView"
                                     "{"
                                     "border : solid black;"
                                     "border-width : 5px 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：
