In this article we will see how we can restore the geometry of the spin box from the saved. Saving of geometry helps in saving current geometry and state for top-level spin box widget which can be done with the help of saveGeometry
. Saving data can be stored in any external file or in any variable and can be restored for other uses as well.
In order to do this we use restoreGeometry
method with the spin box object.
Syntax : spin_box.restoreGeometry(byte_array)
Argument : It takes QByteArray object argument
Return : It returns bool i.e True for success else False
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 )
# saving the geometry
value = self .spin.saveGeometry()
# changing the geometry
self .spin.setGeometry( 10 , 10 , 50 , 50 )
# restoring the old geometry
success = self .spin.restoreGeometry(value)
# setting text to the label
label.setText( "Restored Geometry : " + str (success))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
