In this article we will see how we can get the size increment value of spin box or not. Size increment is used when spin box size is changeable with the main window size. 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. WE can set the size increment value with the help of setSizeIncrement method.
Below is the formula for getting new spin box size when main window get bigger.
width = baseSize().width() + i * sizeIncrement().width() height = baseSize().height() + j * sizeIncrement().height() Here i, j are the size increment in the main window
In order to do this we use sizeIncrement method with the spin box object.
Syntax : spin_box.sizeIncrement()
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 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 size increment self.spin.setSizeIncrement(10, 10) # creating a label self.label = QLabel(self) # making label multi line self.label.setWordWrap(True) # setting label geometry self.label.setGeometry(100, 200, 250, 60) # getting the size increment value value = self.spin.sizeIncrement() # setting text to the label self.label.setText("Size increment : " + str(value)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
