In this article we will see how we can set different size/width borders to the down arrow, basically, when we set border to the down arrow it is of same width for all sides although we can change its color.
In order to do so we have to change the style sheet associated with the combobox, below is the stylesheet code –
Code 1
QComboBox::down-arrow
{
border : solid black;
border-width-top : 5px;
border-width-right : 1px;
border-width-bottom : 10px;
border-width-left : 3px;
}
Code 2
QComboBox::down-arrow
{
border : solid black;
border-width : 5px 1px 10px 3px;
}
Both code perform similar task just code 1 is extended version of code 2.
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) # setting style sheet # adding different border width to down arrow self.combo_box.setStyleSheet("QComboBox::down-arrow" "{" "border : solid black;" "border-width : 5px 1px 10px 3px;" "}") # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() window.show() # start the app sys.exit(App.exec()) |
Output :
