PyQt5 - 在 ComboBox 的项目之间添加多个分隔符

在本文中，我们将看到如何在组合框的项目之间添加多个分隔符，默认情况下没有分隔符。分隔符是两个项目之间的黑线，为了添加分隔符，我们使用 insertSeparator 方法。下面是带有分隔符的组合框项目的表示形式

为了添加多个分隔符，我们将多次使用 insertSeparator 方法，但初始给出最大索引的索引值，然后是第二个最大索引值，依此类推，如果我们首先给出最小索引值，那么其他语句只会增加最小值的大小索引值分隔符。

For adding separator at two places only 
Syntax : 
combo_box.insertSeparator(max(indexs)) 
combo_box.insertSeparator(min(indexs)
Here, indexes is the list of two index
Argument : It takes integer as argument i.e index
Action performed : It will add separator at the given index 
 

下面是实现——

Python3

# 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 combo box widget
        self.combo_box = QComboBox(self)
 
        # setting geometry of combo box
        self.combo_box.setGeometry(200, 150, 150, 30)
 
        # geek list
        geek_list = ["Sayian", "Super Saiyan", "Super Sayian 2", "Super Sayian B"]
 
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
 
        # index list
        indexs = [1, 3, 2]
 
        # adding separator at maximum index
        self.combo_box.insertSeparator(max(indexs))
 
        # adding separator at middle index
        index = 0
        for i in indexs:
            if i > min(indexs) and i < max(indexs):
                index = i
        self.combo_box.insertSeparator(index)
 
        # adding separator at minimum index
        self.combo_box.insertSeparator(min(indexs))
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出 ：
