        my_app = QApplication.instance()
    else:
        my_app = QApplication(sys.argv)
    # create a QTreeWidgetItem with tree columns
    my_tree= QTreeWidgetItem(["Column A"])
    # add date using a for loop 
    for i in range(6):
        list_item_row = QTreeWidgetItem(["Child A-" + str(i)])
        list_item_row.addChild(QTreeWidgetItem(['item1']))
        my_tree.addChild(list_item_row)
    # create my_widget widget
    my_widget = QWidget()
    my_widget.resize(640, 180)
    # create a QTreeWidget named my_tree_widget 
    my_tree_widget = QTreeWidget(my_widget)
    my_tree_widget.setWindowIcon(QIcon('icons/search.png'))
    my_tree.setIcon(0,QIcon('icons/search.png'))
    # my_tree.setText(0,"testtes")
    my_tree_widget.addTopLevelItem(my_tree)

    # show the widget
    my_widget.show()
    # the exit of my_app
    sys.exit(my_app.exec_())
