In this article we will see how we can dump the object tree of the spin box, dumping object tree means to dump a tree of children to the debug output. Object tree is a tree data structure holding child objects of spin box at the nodes.
In order to do this we use dumpObjectTree method
Syntax : spin_box.dumpObjectTree()
Argument : It takes no argument
Return : It returns None
Note: Before Qt 5.9, this function was not constant function.
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, 999999) # setting prefix to spin self.spin.setPrefix("Prefix ") # setting suffix to spin self.spin.setSuffix(" Suffix") # dumping object tree of spin box self.spin.dumpObjectTree() # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() window.spin.setFocus() # start the app sys.exit(App.exec()) |
Output :
