ScrolledFrame Behavior

Is this a bug or expected behavior?

This code generates this layout:

import ttkbootstrap as ttk
from ttkbootstrap.constants import *
from ttkbootstrap.scrolled import ScrolledFrame

class MainFrame(ttk.Window):
    def __init__(self):
        ttk.Window.__init__(self)

        self.geometry('500x300')
        self.title('Tkinter')
        
        self.set_notebook()
        self.set_tab0()
        return

    def set_notebook(self):
        self.nb = ttk.Notebook(self)
        self.nb.place(relx=0, rely=0, relwidth=1, relheight=1)
        return

    def set_tab0(self):
        #self.frm = ScrolledFrame(self, autohide=True)
        self.frm = ttk.Frame(self)
        self.frm.place(relx=0, rely=0, relwidth=1, relheight=1)

        ##Top
        self.frm_top = ttk.Frame(self.frm)
        self.frm_top.pack(fill=BOTH, expand=1)

        ttk.Label(self.frm_top, text='frame 1: top place (10, 25)').place(x=10, y=25)
        
        ttk.Label(self.frm_top, text='frame 1: top pack').pack()

        #middle
        self.frm_middle = ttk.Frame(self.frm)
        self.frm_middle.pack(fill=BOTH, expand=1)

        ttk.Label(self.frm_middle, text='frame 2: middle - pack').pack()

        ttk.Label(self.frm_middle, text='frame 2: middle - place (10, 25)').place(x=10, y=25)

        #Bottom
        self.frm_bottom = ttk.Frame(self.frm)
        self.frm_bottom.pack(side=BOTTOM, fill=X)
        ttk.Label(self.frm_bottom, text='frame 3: bottom - pack').pack()

        #self.nb.add(self.frm.container, text='Test')
        self.nb.add(self.frm, text='Test')
        return

if __name__== '__main__':
    app = MainFrame()
    app.mainloop()

Scrolled:

If I replace the frame (self.frm) with a ScrolledFrame, see how the layout changes: the widget with .place was not displayed and the frame side=bottom does not obey the bottom position:

import ttkbootstrap as ttk
from ttkbootstrap.constants import *
from ttkbootstrap.scrolled import ScrolledFrame

class MainFrame(ttk.Window):
    def __init__(self):
        ttk.Window.__init__(self)

        self.geometry('500x300')
        self.title('Tkinter')
        
        self.set_notebook()
        self.set_tab0()
        return

    def set_notebook(self):
        self.nb = ttk.Notebook(self)
        self.nb.place(relx=0, rely=0, relwidth=1, relheight=1)
        return

    def set_tab0(self):
        self.frm = ScrolledFrame(self, autohide=True)
        #self.frm = ttk.Frame(self)
        self.frm.place(relx=0, rely=0, relwidth=1, relheight=1)

        ##Top
        self.frm_top = ttk.Frame(self.frm)
        self.frm_top.pack(fill=BOTH, expand=1)

        ttk.Label(self.frm_top, text='frame 1: top place (10, 25)').place(x=10, y=25)
        
        ttk.Label(self.frm_top, text='frame 1: top pack').pack()

        #middle
        self.frm_middle = ttk.Frame(self.frm)
        self.frm_middle.pack(fill=BOTH, expand=1)

        ttk.Label(self.frm_middle, text='frame 2: middle - pack').pack()

        ttk.Label(self.frm_middle, text='frame 2: middle - place (10, 25)').place(x=10, y=25)

        #Bottom
        self.frm_bottom = ttk.Frame(self.frm)
        self.frm_bottom.pack(side=BOTTOM, fill=X)
        ttk.Label(self.frm_bottom, text='frame 3: bottom - pack').pack()

        self.nb.add(self.frm.container, text='Test')
        #self.nb.add(self.frm, text='Test')
        return

if __name__== '__main__':
    app = MainFrame()
    app.mainloop()

@antrrax, the scrolled frame has a default width and height like the Canvas widget, however, you can override with pack, place, grid, just as with any other widget.

I’ve added a new parameter called scrollheight which sets the height of the content frame manually in the case that you are using a relative positioning such as in the example above.

self.frm = ScrolledFrame(self, autohide=True, scrollheight=300)

I tested it with the same code as in the first post. At first the problem was solved. Thanks for the quick resolution.
