PyQt5 QComboBox - 设置不同的角落

在本文中，我们将看到如何为组合框设置不同的角，组合框小部件与其他小部件不同，它由许多其他小部件组成，例如文本视图、按钮、行编辑等。

为了使组合框循环，我们必须更改与组合框关联的样式表，下面是样式表代码

QComboBox
{
border : 1px solid black;
border-top-left-radius : 20px;
border-top-right-radius : 2px;
border-bottom-left-radius:5px;
border-bottom-right-radius : 3px;
}

注意：它只会使组合框成为主要小部件，即文本视图部分是圆形的，它对按钮没有影响。

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, 100, 40)
  
        # 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 stylesheet of the combo box
        self.combo_box.setStyleSheet("QComboBox"
                                     "{"
                                     "border : 1px solid black;"
                                     "border-top-left-radius : 20px;"
                                     "border-top-right-radius : 2px;"
                                     "border-bottom-left-radius:5px;"
                                     "border-bottom-right-radius : 3px;"
                                     "}")
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 ：
