In this article we will see how we can set the base size to the spin box, base size is used to calculate a proper spin box size if the spin box defines sizeIncrement. By default, for a newly-created spin box, this property contains a size with zero width and height.In order to set base size we use setBaseSize method.
In order to get base size we use baseSize method.
Syntax : spin_box.baseSize()
Argument : It takes no argument
Return : It returns QSize object
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 prefix to spin self.spin.setPrefix("Prefix ") # setting suffix to spin self.spin.setSuffix(" Suffix") # setting base size self.spin.setBaseSize(250, 40) # creating a label label = QLabel(self) # setting geometry to the label label.setGeometry(100, 200, 300, 30) # getting the base size base = self.baseSize() # setting text to the label label.setText(str(base)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
