In this article we will see how we can set different border color to the line edit part of the combo box when mouse hover over the line edit part, 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 to the QLineEdit object
5. Set border with different color when mouse hover over it
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 )
# 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)
# creating line edit object
line_edit = QLineEdit()
# setting border to the line edit part
# set different border color when mouse hover over it
line_edit.setStyleSheet( "QLineEdit"
"{"
"border : 5px solid black;"
"}"
"QLineEdit::hover"
"{"
"border-color : red green blue yellow"
"}" )
# 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 ())
