PyQt5 QSpinBox – Accessing Maximum value
In this article we will see how we can get the maximum value i.e upper bound of the spin box, by default when we create a spin box it ranges from 0 to 99 i.e its maximum value is 99 although we can change this.
In order to do this we will use spin_box.maximum method
Syntax : spin_box.maximum()
Argument : It takes no argument
Return : It returns integer i.e upper bond
Below is the implementation
# importing librariesfrom PyQt5.QtWidgets import * from PyQt5 import QtCore, QtGuifrom 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 maximum value self.spin.setMaximum(5) # creating label show result self.label = QLabel(self) # setting geometry self.label.setGeometry(100, 200, 200, 40) # getting max value val = self.spin.maximum() # setting text to the label self.label.setText("Max Value : " + str(val)) # create pyqt5 appApp = QApplication(sys.argv) # create the instance of our Windowwindow = Window() window.show() # start the appsys.exit(App.exec()) |
