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
Python3
# 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()) |
Output :
