I've a simple GUI thats shows the users some options, after putting the number of the initial options to be shown. In this case, 4:

initial

By clicking on Add row you can add a row to the GUI. The thing is that if the user wants 100 options, the GUI becomes extra big and all the options are not shown. big

So I would like to have a scrollbar only on the options space, not the rest parts. Sorry for the bad Photoshop, but I would like to have something like this: desiredsolution

The options space is the FrameTwo, so I would like to have the entire FrameTwo inside of scrollbar like the image above.

FrameOne is used to put an image I removed to make this example more simple. And FrameThree are the buttons you can see at the bottom of the GUI.

So it would be very helpful if someone could give me a hand and tell me how to put the entire FrameTwo inside of a scrollbar as you can see on the third image.

Thanks in advance.

  • As I see there are no anwers, I would like to know if it's possible to build a fixed size interface, of for example 500x400 and put a scrollbar for the entire thing. Thanks. – Avión Oct 10 '13 at 08:19

One of your problems, is that "frameTwo" has no limits to it's size. If you don't limit it's size, any scrollbar you add, never will act. But limiting the size of you frame have the inconvenient of limit the number of lines you can grid, making the scrollbar useless again.

A solution is creating a frame inside the "frameTwo", to receive the pieces you create. This way, by one hand, allow you to limit the size of "frameTwo" and attach the scrollbar to it, and by other hand, allow you to grid the pieces you add to the frame located inside "frameTwo", named, let's say, "ListFrame". when "ListFrame" size becomes bigger than "frameTwo" size, you can now make the scrollbar work.

I change your code with the changes mentioned above. Check it out. The changes are commented in the code. Sorry for the short explanation, but i'm a bit hurry. I may edit this answer when I have more time.

You have option menus, labels, entry boxes, and checkbuttons in FrameTwo. How would you expect a scrollbar for the entire frame would work? Would it scroll all widgets at the same time? Tkinter scrollbars are generally attached to listboxes, canvases, entry widgets, and text fields. http://effbot.org/zone/tkinter-scrollbar-patterns.htm Come up with a simple example that illustrates the problem for further help.
