PyQt5 QSpinBox – Getting Children Region

Last Updated : 17 May, 2020

In this article we will see how we can get the children region, children region holds the combined region occupied by the spin box’s children. In order to do this we use childrenRegion method. If we delete all the children of the spin box then this property will return an empty region.

In order to do this we use childrenRegion method.

Syntax : spin_box.childrenRegion()

Argument : It takes no argument

Return : It returns QRegion object

Note : Hidden children are excluded

Below is the implementation

# importing libraries

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 prefix to spin 
        self.spin.setPrefix("Prefix ") 
  
        # setting suffix to spin 
        self.spin.setSuffix(" Suffix") 
  
        # creating a label 
        self.label = QLabel("Label ", self) 
  
        # setting geometry to the label 
        self.label.setGeometry(100, 200, 200, 70) 
  
        # getting the children region 
        children_region = self.spin.childrenRegion() 
  
        # setting text to the label 
        self.label.setText(str(children_region)) 
  
        # making label multi line 
        self.label.setWordWrap(True) 
  
  
# create pyqt5 app 
App = QApplication(sys.argv) 
  
# create the instance of our Window 
window = Window() 
  
# start the app 
sys.exit(App.exec())
