In this article we will see how we can set border to the line edit part of the combo box. Line edit part 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. Below is the representation of normal combo box vs combo box whose line edit part is having border.
In order to do this, follow these steps –
1. Create a combo box
2. Add item to the combo box
3. Create a QLineEdit object
4. Set border to the QLineEdit object
5. Add QLineEdit object to the combo box
Syntax :
# creating line edit object line_edit = QLineEdit() # setting border to the line edit line_edit.setStyleSheet("QLineEdit" "{" "border : 2px solid green;" "}") # adding line edit object to the combo box self.combo_box.setLineEdit(line_edit)
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 )
# 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
line_edit.setStyleSheet( "QLineEdit"
"{"
"border : 2px solid green;"
"}" )
# 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 ())
