In this article we will see how we can set the minimum value i.e lower bound of the spin box, by default when we create a spin box it ranges from 0 to 99 i.e its minimum value is 0 although we can change this.
In order to do this we will use spin_box.setMinimum method.
Syntax : spin_box.setMinimum(n)
Argument : It takes integer as argument
Return : It returns None
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, 100, 40) # setting minimum value self.spin.setMinimum(-10) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
