PyQt5 QComboBox – Change border style when it is in off state and when it get pressed
In this article we will see how we can change the border style of the combo box when it is in off state and get pressed, 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 in off state and it gets pressed else normal border will be visible.
In order to do this we have to change the style sheet associated with the combo box, below is the style sheet code
QComboBox::!on:pressed
{
border : 4px black;
border-style : dotted;
}
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, 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 when it is in off state # and get pressed self.combo_box.setStyleSheet("QComboBox" "{" "border : 4px solid black" "}" "QComboBox::! on:pressed" "{" "border : 4px black;" "border-style : dotted;" "}") # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
