In this article we will see how we can get the preferred height of the spin box according to the width. Height depending on the width means that when ever the width changes height also changes. By default height don’t depends on the width.
Note : If spin box has a layout, the default implementation returns the layout’s preferred height. if there is no layout, the default implementation returns -1 indicating that the preferred height does not depend on the width.
In order to do this we use heightForWidth method with the spin box object.
Syntax : spin_box.heightForWidth(width)
Argument : It takes integer as argument
Return : It returns integer
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(1, 999999) # setting prefix to spin self.spin.setPrefix("PREFIX ") # setting suffix to spin self.spin.setSuffix(" SUFFIX") # creating a label label = QLabel(self) # making the label multi line label.setWordWrap(True) # setting geometry to the label label.setGeometry(100, 200, 200, 60) # getting preferred height of the spin box with current width value = self.spin.heightForWidth(250) # setting text to the label label.setText("Preferred height " + 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 :
