Some time ago I posted to various gtk related lists about reducing
padding between treeview rows. I got the response below, which seemed
promising as a hack fix for the single area of concern that initially
sparked my interest in reducing the space between rows. My initial
interest was to reduce the space between rows in the list of plugins in
ardour's (www.ardour.org) mixer strip, as shown in the link below (the
single column treeview where it says PLUGIN1 and PLUGIN2). I believe 3
lines should fit where there is only 2 in the image.

If this were my only area if interest in reducing space between treeview
rows, I would have given this method a try. I've realized though, that
it's throughout gnome that I think the treeview spacing is way too much.
I believe it to be a bug in gtk that its not possible via code or
style properties to reduce vertical spacing right down to the point
where the text touches each other if desired. Perhaps its actually
within pango where the problem lies, i'm not sure about that. The
following link shows my desktop, with my gtk theme modified to reduce
treeview spacing as much as possible, compared to the KDE file manager
(shown via K3B) with no modifications at all. I've been a long time kde
user, and only recently switched to gnome to surround myself in the
environment that I have recently began studying and developing in. Ive
tried migrating to gnome in the past, and always reverted back to kde
after being just unhappy with it as a desktop. These days, I'm happy to
say, gnome has finally come so far that I'm happy using it as my
desktop, and if this vertical treeview spacing issue can be resolved, I
will have everything I desire about the look n feel of kde.

By default, the spacing is even greater than shown. I used
GtkTreeView::vertical-separator and ythickness settings in my gtkrc file
to get it down this far.
Should I create a new bugzilla report from this post?

What I do to get around this, is in my custom-cell-renderer (which may be hacky but it works for me) is to decrease from 'height' in its
custom-cell-renderers 'get_size' function so when its finally rendered its closer to 'my_desired_height' as we use the space for rendering too (see below).
<snip>
if (height)
{
gint vertical_separator;
*height = my_desired_height;
/* Each row has a vertical-separator equal to 2, decrease by this
amount as we render to the blank area. */
gtk_widget_style_get (widget, "vertical-separator",
&vertical_separator, NULL);
*height -= vertical_separator * 2;
}
</snip>
and then in the custom-cell-renderers 'render' function I then add the height back again.
/* Each row has a vertical-separator equal to 2, increase by this amount to
render over this blank area. */
gtk_widget_style_get (widget, "vertical-separator", &vertical_separator,
NULL);
height += vertical_separator * 2;
This way though the space is still there, you are actually rendering over it,
giving the impression that its not there. Hope you get what I mean.

Yes, I set it to 0, along with ythickness, used tiny fonts, set the y_pd
property of the CellRenderer to 0, tried every theme I have and even
bogus rc file (no theme). Nothing will bring the the rows any closer
together. At the very closest 2 rows will come together in say the file
manager, there is still enough room for almost another row of text. I
want the ability to make one row of text to touch the next. Not that I
would, but I want to get really close to that. It's looking like a gtk
bug to me.

Have you checked out the vertical_separator style property of the GtkTreeView.
Its this that is adding the extra spacing.

I've tried different themes as well as setting xthickness and ythickness
manually in both my theme's rc file and the applications rc file.

I am trying to reduce the spacing between rows of text in a single
column treeview. Ive been experimenting with both the ypad and height
properties. They both work in adding space, but neither will take any
space out. Seems like anything less than about ypad=3 doesn't do
anything. With a font size of 8, there is almost enough space between
rows to fit another row in between them. Even trying a tiny font size
for troubleshooting purposes, doesnt bring the rows any closer together.
Can someone help, please?
If it's not because late GTK+ versions have changed their behaviour here
then likely your current GTK+ theme is interfering with your pad
setting. Try some other themes. Basically, ypad = 0 should make a
difference. I use it, too. Unfortunately, as also the vartype shows,
negative ypad values are not supported.
