Re: GtkTextView geometry

["Frank W. Miller" <fwmiller cornfed com>]

Thanks for the reply.

Let me be a bit more specific.  I have a GtkNotebook in a GtkWindow.  In
one of the tabs of the notebook, I would like to insert a GtkTextView.
This GtkTextView will have an associated GtkTextBuffer.  Before your
email I was just gtk_container_add()ing the GtkTextView to the tab of
the notebook.  When I did this, the size of the top-level window would
expand to the size of the text included in the GtkTextView.

What I would like is to set the size of the top-level window (using
gtk_window_set_default() is the way I'm doing it now), insert the
GtkTextView into the notebook tab and have the GtkTextView conform to
the set window size.  If the text in the GtkTextView is too big to be
displayed, the GtkTextView would automatically bring up horiz and
vertical scrollbars to allow you to move around in the associated
GtkTextBuffer.

I'd also like to be able to append and prepend text to the GtkTextBuffer
and have the GtkTextView update without its size changing.

So, I was not using the GtkScrolledWindow before.  I tried inserting
that as you suggested using both gtk_container_add() and
gtk_scrolled_window_add_with_viewport().  In both cases, the GtkTextView
does not appear in the tab.

Another interesting point.  When I looked at the developer documentation
for gtk_scrolled_window_add_with_viewport, I saw the following:

"The viewport scrolls the child by moving its GdkWindow, and takes the
size of the child to be the size of its toplevel GdkWindow. This will be
very wrong for most widgets that support native scrolling; for example,
if you add a widget such as GtkTreeView with a viewport, the whole
widget will scroll, including the column headings. Thus, widgets with
native scrolling support should not be used with the GtkViewport proxy."

This seems to indicate that there is some sort of native scrolling
associated with GtkTextView.  If so, that's what I'm probably really
interested in.

Thanks,

P.S. BTW, if you want to get an idea of the GUI I'm working with, look
at http://www.cornfed.com/images/cornfedsipua/advanced/contacts.gif

I'm adding a tab to this that will have call history in a GtkTextView.
