Setting the scroll position of a GtkTextView in GtkScrolledWindow after render

[Andri Möll <andri dot ee>]

Hey,

I can't figure out if it's me or something's amiss. I'm trying to set 
the scroll position after rendering a GtkTextView in a 
GtkScrolledWindow, but it's reset to a different value, if it works at 
all. I've so far tried to set the vertical adjustment value both after 
GtkScrolledWindow is mapped or its child (GtkTextView) size-allocated. 
When using a GtkListBox instead of a GtkTextView and setting the 
adjustment's value on "size-allocate", it works. No such luck with a 
GtkTextView, however.
The peculiar thing with the GtkTextView is, while the adjustment reports 
its upper bound to be, for example, 588 and its value 0, immediately 
after setting it to 493, it reports its value as 11. I figure 
"size-allocate" is still the wrong event to use here given the 
adjustment is in flux. What would the right path be to consistently set 
the scroll position after the first render, and later, after resetting 
the GtkTextView's buffer?
This is on Arch Linux with gtk3 v3.24.7+25+g17665f06e3-1.

Thanks in advance!
