PyQt5 QComboBox 改变边框样式

PyQt5 QComboBox 改变边框样式

在这篇文章中,我们将看到如何改变组合框的边框样式,边框样式可以是虚线、虚线等。当我们给组合框设置边框时,它是连续的,尽管我们可以改变它。

为了做到这一点,我们必须改变与组合框相关的样式表,下面是样式表的代码

QComboBox
{
border : 2px black;
border-style : dotted;
}

以下是实施情况

# 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, 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
        # set the border style
        self.combo_box.setStyleSheet("QComboBox"
                                     "{"
                                     "border : 2px black;"
                                     "border-style : dashed;"
                                     "}")
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
