In this article we will see how we can set background image to the spin box for its various states. There are basically three states of the spin box one is normal state, second is the hover state i.e when cursor is on the spin box and third is the pressed state i.e when mouse button is pressed.
In order to do this we have to change the style sheet associated with the spin box, below is the style sheet code
QSpinBox
{
border : 1px solid black;
background-image : url(image1.png);
}
QSpinBox::hover
{
background-image : url(image2.png);
}
QSpinBox::pressed
{
background-image : url(image3.png);
}
This will add three different background image for each state, there are also some additional states like anti-hover (!hover) and anti-pressed(!pressed) these are opposite of hover and pressed state respectively.
Note : We have to add border for the normal state else image will not get displayed as PyQt5 will not allow it to overwrite the style sheet
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 spin box self.spin = QSpinBox(self) # setting geometry to spin box self.spin.setGeometry(100, 100, 250, 40) # setting range to the spin box self.spin.setRange(0, 9) # setting prefix to spin self.spin.setPrefix("PREFIX ") # setting suffix to spin self.spin.setSuffix(" SUFFIX") # setting style sheet # adding background image # adding background image for hover and pressed state self.spin.setStyleSheet("QSpinBox" "{" "border : 2px solid black;" "background-image : url(image.png);" "}" "QSpinBox::hover" "{" "background-image : url(skin.png);" "}" "QSpinBox::pressed" "{" "background-image : url(logo.png);" "}" ) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
