In this article we will see how we can set background image to the line edit part of the non-editable combo box when mouse hover over it. Line edit is the part of combo box which is used to see the selected text and edit the text. In order to set and get the line edit object of the combo box we use setLineEdit and lineEdit method.
Note : When we add line edit to the combo box it make the combo box editable therefore there is a need to make line edit non-editable.
In order to do this we have to do the following
1. Create a combo box
2. Add items to the combo box
3. Create a QLineEdit object
4. Add background image to the QLineEdit object when mouse hover over it
5. Make the line edit object non editable
6. Add line edit object to the combo box
Syntax :
# creating line edit object
line_edit = QLineEdit()
# setting style sheet of line edit
# adding background image when mouse hover over it
line_edit.setStyleSheet("QLineEdit::hover"
"{"
"background-image : url(logo.png);"
"border : 2px solid black;"
"}")
# making line edit object non editable
line_edit.setReadOnly(True)
# adding line edit to the combo box
combo_box.setLineEdit(line_edit)
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) # creating line edit object line_edit = QLineEdit() # setting style sheet of line edit # adding background image when mouse hover over it line_edit.setStyleSheet("QLineEdit::hover" "{" "background-image : url(logo.png);" "border : 2px solid black;" "}") # making line edit object non editable line_edit.setReadOnly(True) # adding line edit to the combo box self.combo_box.setLineEdit(line_edit)# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()window.show()# start the appsys.exit(App.exec()) |
Output :
