It seems `ScrolledFrame` doesn't work for `place layout`.

Hello, @alejandroautalan , it seems ScrolledFrame doesn't work for place layout.
my code:

import tkinter as tk
from pygubu.widgets.scrolledframe import ScrolledFrame

root = tk.Tk()

scrolledframe =  ScrolledFrame(
    root,
    scrolltype="horizontal"
)

prev_x = 0
for i in range(100):
    label= Label(
        scrolledframe.innerframe,
        text="ABCD ")
    label.place(x=prev_x, y=0)
    prev_x += label.winfo_reqwidth()    

scrolledframe.place(x=0, y=0, height=500, width=200)

root.mainloop()

and the widget appears without scrollbar.

Hello @larryw3i thanks for the report. It seems that the method winfo_reqwidth is not informing correctly about the size of the frame when contains placed children widgets.

import tkinter as tk

root = tk.Tk()
root.geometry("200x500")
frame =  tk.Frame(root)

prev_x = 0
for i in range(100):
    label= tk.Label(
        frame,
        text="ABCD ")
    label.place(x=prev_x, y=0)
    #print(prev_x)
    prev_x += label.winfo_reqwidth()    
frame.place(x=0, y=0, width=200, height=500)

def print_width():
    print(f"Width: {frame.winfo_width()}")
    print(f"ReqWidth: {frame.winfo_reqwidth()}")

root.after(800, print_width)
root.mainloop()

Output:

Width: 200
ReqWidth: 1

I will investigate that and find a solution. Regards

As indicated on this page, the place manager does not compute geometric propagation. Therefore to support place in the ScrolledFrame, the size of the innerframe it has to be calculated manually.

@alejandroautalan Ok, It looks normally, I really appreciate your help.
