Hello, husnih
Sorry for the delay, I have some work to do.

In code, you can manupulate as you like the widgets you defined and configured with pygubu-designer.

To do so, you mus get the widget instance using the builder method _get_object(widget_id)_.
Once you do that, you can call any method for that widget.

For example to add data into a treeview widget you use the _insert()_ method off the treeview instance.

A quick example:

#!/usr/bin/env python3
import tkinter as tk
import random
import pygubu


class MyApplication:
    def __init__(self, master):
        self.builder = builder = pygubu.Builder()
        builder.add_from_file("treeview.ui")

        # Create first the main window:
        mainwindow = builder.get_object('mainwindow', master)
        # Get the treeview instance
        tree = builder.get_object('treeview')

        # Populate treeview
        for i in range(0, 6):
            label = 'Level {0}'.format(i)
            column_data = (random.randint(0, 1000), random.randint(0, 100))
            itemid = tree.insert('', tk.END, text=label, values=column_data)
            for j in range(0, 4):
                label = 'Item {0}'.format(j)
                column_data = (random.randint(0, 1000), random.randint(0, 100))
                tree.insert(itemid, tk.END, text=label, values=column_data)

if __name__ == '__main__':
    root = tk.Tk()
    app = MyApplication(root)
    root.mainloop()

The ui file:
