Mehmet,
An idle handler would be a good fit here. I assumed that you are
creating and filling textviews during the startup of your program and
possibly before you enter the main_loop or gtk_main. Or possibly in a
routine that does everything at once. Here is the potential problem:
your create and populate actions require some additional gtk messages to
be processed, which are waiting to get serviced by the gtk_main() loop.
So thing s will not appear to settle down until after the gtk_main has
been allowed to run. Using an idle handler puts your call to a
Position/Size routine at the back of the waiting queue of needed
messages, so by the time it's processed the other messages have done
their job and all the textviews/scrollbars/gtkvboxes, and scrolled
windows have settled down. -- wait, this assumes you issued a
gtk_widget_show{_all} on the main window containing all this stuff! Its
the gtk_widget_show that starts the cascade of messages which includes
the size and realize messages.
g_idle_add() or g_timeout_add(250,...) show do the trick.
