In this article we will see how we can add border to the combo box when it is in off state and it get pressed. OFF state is basically when the combo box list view is not open. This customized border appear only when combo box will be in off state and it is pressed. In order to do this we have to change the style sheet associated with the combo box, below is the style sheet code
QComboBox::!off:pressed
{
border : 3px solid blue;
}
Below is the implementation
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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 Sayian", "Super Sayian 2", "Super Sayian B"] # adding list of items to combo box self.combo_box.addItems(geek_list) # editing style sheet code of combo box # adding border to the combo box when it is in off state # and when it get pressed self.combo_box.setStyleSheet("QComboBox::! on:pressed" "{" "border : 3px solid blue;" "}")# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
