[Java-gnome-developer] Window automatic resizing when a widget hide

[Khiraly <khi...@gm...>]

Hi!

I have a window, where are two widget side by side: one TextView widget
(main_chat) and one TreeView widget (userlist)
By default, the TreeView widget is hidden.

Here is an another screenshot, where the TextView widget and the
TreeView widget is visible:

If I hide the TreeView widget, then the TextView widget fill the rest
place. (The main windows does not resize automatically.) Its how it is
supposed to work.

If I show the TreeView widget again, than the window resize
automatically, because the size of TextView does not changed and the
TreeView widget is placed aside.

I dont like this feature. I would like if the windows width
(horizontally) didnt changed.

This automatic resizing continue as long as the TextView widget make
wrapping. The horizontal size its just growing.
