In this article we will see how we can set background image to the combo box when it is editable and it is in on state. By default combo box has no image although we can set image to it. Background image will appear only when combobox is in editable state and it is in on state. ON state is when list view is open. Normal combo box can be made editable 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
{
background-image : url(image.png);
border : 2px solid black;
}
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 check-able combo box object self.combo_box = QComboBox(self) # making combo box editable self.combo_box.setEditable(True) # setting geometry of combo box self.combo_box.setGeometry(200, 150, 200, 80) # 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 style sheet of the combo box # adding background image to the combo box it is in editable state # and when combo box is in on state self.combo_box.setStyleSheet("QComboBox::editable:on" "{" "background-image : url(logo.png);" "border : 2px solid black;" "}")# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()window.show()# start the appsys.exit(App.exec()) |
Output :
When it comes in the on state
