In this article we will see how we can get the child of the spin box at the given position inside the spin box, child are basically the component of the spin box, for example, the spin box main child is its QLineEdit which is used to see the value and set the value.
In order to do this we use childAt method.
Syntax : spin_box.childAt(x, y)
Argument : It takes position as argument it can be x, y co-ordinates or the QPoint object
Return : It returns child at given position if there is no child it return None
Note : The co-ordinates are not of the window co-ordinate system they are in spin box co-ordinate system
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 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 child at the point 10, 10 child = self.spin.childAt(10, 10) # setting text to the label self.label.setText(str(child)) # 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()) |
Output :
