In this article we will see how we can set different border color to the line edit part of the non editable combo box, line edit is the part of combo box which displays the selected item, it is editable by nature. In order to set and access the line edit object we use setLineEdit and lineEdit method respectively.
In order to do this we have to do the following :
1. Create a combo box
2. Add item to the combo box
3. Create a QLineEdit object
4. Set border with different color to the QLineEdit object
5. Make line edit object non-editable(read-only)
6. Add QLineEdit object to the combo box
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, 150, 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 border to the line edit part # set different border color line_edit.setStyleSheet("QLineEdit" "{" "border : 5px solid ;" "border-color : red green blue yellow" "}") # making line edit object read only line_edit.setReadOnly(True) # adding line edit object to the combo box self.combo_box.setLineEdit(line_edit) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
