In this article we will see how we can change the border style of the combo box when it is non-editable and is in on state, border style can be dotted, dashed etc. When we set border to the combo box it is continuous although we can change it. Styled border will be only visible when combo box is non-editable and in on state. In order to do this we have to change the style sheet associated with the combo box, below is the style sheet code
QComboBox::!non-editable:on { border : 4px black; border-style : dotted; }
Below is the implementation
Python3
# 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 , 100 , 40 )
# 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)
# setting stylesheet of the combo box
# set the border style wen it is non-editable
# and in on state
self .combo_box.setStyleSheet("QComboBox"
"{"
"border : 4px solid black"
"}"
"QComboBox::! editable:on"
"{"
"border : 4px black;"
"border - style : dashed;"
"}")
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
