In this article we will see how we can add border to the editable combo box when it is in on state. ON state is basically when the combo box list view is open. This customized border appear only when combo box will be in on state and is editable. Editable combo box can be created with the help of setEditable method.
In order to do this we have to change the style sheet associated with the combo box, below is the style sheet code
QComboBox::editable:on
{
border : 3px solid blue;
}
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 combo box widget self.combo_box = QComboBox(self) # setting geometry of combo box self.combo_box.setGeometry(200, 150, 150, 30) # 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) # editing style sheet code of combo box # adding border to the combo box when it is editable # and is in ON state self.combo_box.setStyleSheet("QComboBox::editable:on" "{" "border : 3px solid red;" "}") # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
