coding a scrollable frame with a ttk.notebook inside works. But the scrollbar / notebook has a fixed size. How can I change it?
from tkinter import Canvas, Scrollbar, Button, Tk
from tkinter.ttk import Frame, Notebook
class VerticalScrolledFrame(Frame):
"""A pure Tkinter scrollable frame that actually works!
* Use the 'interior' attribute to place widgets inside the scrollable frame
* Construct and pack/place/grid normally
* This frame only allows vertical scrolling
"""
def __init__(self, parent, *args, **kw):
Frame.__init__(self, parent, *args, **kw)
# create a canvas object and a vertical scrollbar for scrolling it
vscrollbar = Scrollbar(self, orient='vertical')
vscrollbar.pack(fill='y', side='right', expand='false')
canvas = Canvas(self, bd=0, highlightthickness=0,
yscrollcommand=vscrollbar.set)
canvas.pack(side='left', fill='both', expand='true')
vscrollbar.config(command=canvas.yview)
# reset the view
canvas.xview_moveto(0)
canvas.yview_moveto(0)
# create a frame inside the canvas which will be scrolled with it
self.interior = interior = Frame(canvas)
interior_id = canvas.create_window(0, 0, window=interior,
anchor='nw')
# track changes to the canvas and frame width and sync them,
# also updating the scrollbar
def _configure_interior(event):
# update the scrollbars to match the size of the inner frame
size = (interior.winfo_reqwidth(), interior.winfo_reqheight())
canvas.config(scrollregion="0 0 %s %s" % size)
if interior.winfo_reqwidth() != canvas.winfo_width():
# update the canvas's width to fit the inner frame
canvas.config(width=interior.winfo_reqwidth())
interior.bind('<Configure>', _configure_interior)
def _configure_canvas(event):
if interior.winfo_reqwidth() != canvas.winfo_width():
# update the inner frame's width to fill the canvas
canvas.itemconfigure(interior_id, width=canvas.winfo_width())
canvas.bind('<Configure>', _configure_canvas)
root = Tk()
class Overview:
def __init__(self):
#mainframe to make a scrollable window
self.mainframe = VerticalScrolledFrame(root)
self.mainframe.grid(row=0, column=0)
# create a notebook
self.TNotebook_Overview = Notebook(self.mainframe.interior)
self.TNotebook_Overview.grid(row=0, column=0)
self.TNotebook_Overview.configure(takefocus="")
self.Frame_Overview = Frame(self.TNotebook_Overview)
self.TNotebook_Overview.add(self.Frame_Overview)
self.TNotebook_Overview.tab(0, text="Table", compound="left",underline="-1", )
buttons = []
for i in range(30):
buttons.append(Button(self.Frame_Overview, text="Button " + str(i)))
buttons[-1].grid(column=0, row=i)
if __name__ == "__main__":
ov = Overview()
root.title('Overview Items Database')
root.geometry('800x800+10+10')
root.configure(background="#4C7274")
root.grab_set()
root.mainloop()
I expect an expanded scrollable notebook/frame filled entire Tk() window.
Because the "ai" of stackoverflow don't allow use code from another thread, here is code https://pastebin.com/ykJGViAz
