PyQt5 QComboBox – Change border style when it editable and off state

In this article we will see how we can change the border style of the combo box when it is editable and is in off state, border style can be dotted, dashed etc. When we set border to the combo box it is continuous although we can change it. Styled border will be only visible when combo box is editable and off state.
In order to do this we have to change the style sheet associated with the combo box, below is the stylesheet code
QComboBox::editable:!on
{
border : 4px black;
border-style : dotted;
}
Below is the implementation
# 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)           # making 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 stylesheet of the combo box         # set the border style when it is editable         # and in off state         self.combo_box.setStyleSheet("QComboBox"                                     "{"                                     "border : 4px solid black"                                     "}"                                     "QComboBox::editable:! on"                                     "{"                                     "border : 4px 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())  | 
Output :
