In this article we will see how we can set different border width to the combo box when combo box is in the off state and mouse hover over it, when we set border to the combo box it is of same width for all the sides although we can change width of each sides respectively, border with different width will only appear when combo box is off state and cursor is on the combo box else it will show normal border. Off state refer to when item view is not open. In order to do so we have to change the style sheet associated with the combo box below is the style sheet code
Code 1
QComboBox::!off:hover
{
border : solid black;
border-width-top : 1px;
border-width-right : 5px;
border-width-bottom : 2px;
border-width-left : 10px;
}
Code 2
QComboBox::!on:hover
{
border : solid black;
border-width : 1px 5px 2px 10px;
}
Both code perform similar task just code 1 is extended version of code 2. Below is the implementation
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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) # setting style sheet # adding border to combo box # adding different width border when it is OFF and mouse hover over it self.combo_box.setStyleSheet("QComboBox" "{" "border : 5px solid black;" "}" "QComboBox::! on:hover" "{" "border : solid black;" "border-width : 1px 5px 2px 10px;;" "}")# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()window.show()# start the appsys.exit(App.exec()) |
Output :
