PyQt5 QSpinBox – How to get the size hint
In this article we will see how we can get the size hint of the spin box. Size hint is the recommended size for the spin box. Recommended size is related to the layout size if the window size is large and there are few widgets then size hint would be larger than normal.
In order to do this we use sizeHint
method with the spin box object.
Syntax : spin_box.sizeHint()
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" ) # 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 hint value = self .spin.sizeHint() # setting text to the label self .label.setText( "Recommended Size : " + str (value)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
