In this article we will see how we can add border to the up arrow when it is in anti pressed state, we know there exist two buttons up and down in spin box and up arrow is the internal part of the up button. Up arrow is the subset of up button and up button is subset of spin box. By default there is no border to the up arrow although we can add it, customized border will only appear when it didn’t get pressed. In order to do this we have to change the style sheet code associated with the spin box, below is the stylesheet code
QSpinBox::up-arrow:!pressed
{
border : 4px solid red;
}
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 spin box self.spin = QSpinBox(self) # seting geometry to spin box self.spin.setGeometry(100, 100, 250, 60) # setting prefix to spin self.spin.setPrefix("Prefix ") # setting suffix to spin self.spin.setSuffix(" Suffix") # setting style sheet to the spin box # adding border to the down button # adding border to the up arrow # and when it is in anti pressed state self.spin.setStyleSheet("QSpinBox::up-button" "{" "border : 3px solid lightgreen;" "}" "QSpinBox::up-arrow:! pressed" "{" "border : 4px solid red;" "}")# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
