PyQt5组合框不可编辑时的不同边框宽度

在这篇文章中，我们将看到如何在组合框处于非编辑状态时为其设置不同的边框宽度，当我们为组合框设置边框时，虽然我们可以分别改变每个边框的宽度，但所有边框的宽度都是一样的，只有当组合框处于非编辑状态时，才会出现不同的边框，否则将显示正常边框。可编辑的组合框可以在setEditable方法的帮助下被创建。为了做到这一点，我们必须改变与组合框相关的样式表，下面是样式表代码 代码1

QComboBox::!editable
{
border : solid black;
border-width-top : 1px;
border-width-right : 5px;
border-width-bottom : 2px;
border-width-left : 10px;
}

代码2

QComboBox::!editable
{
border : solid black;
border-width : 1px 5px 2px 10px
}

这两个代码执行类似的任务，只是代码1是代码2的扩展版本。下面是执行情况

# 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 a check-able combo box object
        self.combo_box = QComboBox(self)

        # setting geometry of combo box
        self.combo_box.setGeometry(200, 150, 150, 80)

        # amking combo box editable
        # self.combo_box.setEditable(True)

        # 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 border to combo box
        # adding different width border when it is non-editable
        self.combo_box.setStyleSheet("QComboBox"
                                     "{"
                                     "border : 5px solid black;"
                                     "}"
                                     "QComboBox::! editable"
                                     "{"
                                     "border : solid black;"
                                     "border-width : 1px 5px 2px 10px;"
                                     "}")


# 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：
