In this article we will see how we can scroll the spin box. Scrolling can be done by scrolling the pixels to right and scrolling pixels to downward. After scrolling, the widgets will receive paint events for the areas that need to be repainted. For spin box that Qt knows is to be opaque, this is only the newly exposed parts. For example, if an opaque spin box is scrolled 8 pixels to the left, only an 8-pixel wide stripe at the right edge needs updating.
Note : If spin box uses contents propagation, a scroll will cause an update of the entire scroll area.
In order to do this we use scroll method with the spin box object.
Syntax : spin_box.scroll(right, down)
Argument : It takes two integer as argument
Return : It returns None
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) # setting geometry to spin box self.spin.setGeometry(100, 100, 250, 40) # setting range to the spin box self.spin.setRange(1, 999999) # setting prefix to spin self.spin.setPrefix("PREFIX ") # setting suffix to spin self.spin.setSuffix(" SUFFIX") # scrolling the spin box self.spin.scroll(-5, 6) # create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
