Python uses different GUI applications that are helpful for the users while interacting with the applications they are using. There are basically three GUI(s) that python uses namely Tkinter, wxPython, and PyQt. All of these can operate with windows, Linux, and mac-OS. However, these GUI applications have many widgets i.e, controls that are helpful for the user interaction with the application. Some of the widgets are buttons, list boxes, scrollbar, treeview, etc.
Note: For more information, refer to Python GUI – tkinter
This widget is helpful in visualizing and permitting navigation over a hierarchy of items. It can display more than one feature of every item in the hierarchy. It can build a tree view as a user interface like in Windows explorer. Therefore, here we will use Tkinter in order to construct a hierarchical treeview in the Python GUI application.
Let’s see an example of constructing a hierarchical treeview in Python GUI application.
The GUI would look like below:
In the above output, a hierarchical treeview is created. Where, GeeksforGeeks is the parent with Computer Science, GATE papers and Programming Languages as its child. And all the child have their respective attributes attached to them. At last, move() method is called here in order to connect all the children to the parent tree.
