Changing GtkScrolledWindow's scrolling behavior doesn't work.

[Lee Fallat <ircsurfer33 gmail com>]

Hey GTK fans,

Recently I've been trying to adjust scrolling such that when the
scroll wheel is used, the window will scroll the height of a font. I
am using this for developing a text editor (not important though). To
clarify I'm aiming to have it scroll one line at a time.

I have tried using the following in my code, but it has had no effect.

    GtkAdjustment *vadjust =
gtk_scrolled_window_get_vadjustment(source_view_window);
    gtk_adjustment_set_step_increment(vadjust, 12); // 12 is arbitrary
    gtk_scrolled_window_set_vadjustment(source_view_window, vadjust);

...I've been told by someone on IRC (irc.gnome.org #gtk+), that this
is being overridden in the code, and that I'll have to go change it.
Is this the case? If so, is anyone interested in a patch that will
allow this to be changed by setting an alternative GtkAdjustment?...

Thank you,

Lee
