ScrolledWindow with TreeView is not behaving as expected

[Enrico Minack-2]

Hi pygtk users,

I am facing an unexpected behavior of a Gtk.Window with a ScrolledWindow
containing a TreeView. The window always has minimal size. The behavior
that I desire would be that the Gtk.Window scales as the TreeStore /
TreeView grows until it reaches the limit of the screen. This happens
without the ScrolledWindow. With a ScrolledWindow, the scroll bars then
should appear when the TreeView does not fit the screen.

I attached demo code. The set_policy method does not lead to the desired
behavior.

I'd highly appreciate any hints how the resize behavior of the
ScrollWindow could be manipulated into the desired direction.

Kind regards,
Enrico Minack

Hi Enrico,
in my opinion the scrolledwindow behaves correctly.
The scrolledwindow just takes the size of his parent and can hold child
widgets of any dimension thanks to the scrollbars.
The scrolledwindow is not supposed to change size according to what you place inside.
Cheers,
Giuseppe.

Giuseppe Penone already answered correctly.

You find a workarounds (a bit old and possibly buggy) here:

Also see this thread if you're interested on some discussion on the
