Here's a more complex tree, some of of the files in
my music collection. (It's not exactly how GTK would show it, but
close enough.)

Hi, Igor,
The row-activated handler calls:
void
user_function (GtkTreeView *tree_view,
GtkTreePath *path,
GtkTreeViewColumn *column,
gpointer user_data)
{
}
so what you need is :
gint *indices = gtk_tree_path_get_indices (path);
which will return an integer vector ow the row, column, sub-column, subsub-column... depending on the topgraphy of your tree. (You can get the depth of the tree--thus the number of entries in the vector--with:
gint len = gtk_tree_path_get_depth (path);
)
If it's a simple two-dimensional tree, the column number will be indices[1], but you might want to make sure that the tree depth is at least two before doing that or you might be pointing past the end of the indices array.
BTW, what do you mean by saying: "simple 2-dimensional tree"?
Is there going to be n-dimensional tree? How it will be represented on
the screen? Do you have a screenshot?
Thank you.
By the way, don't try to free the indices array--it points to a GTK internal structure.
HTH,
Chris

Take a look at
gint * gtk_tree_path_get_indices (GtkTreePath *path);
with the "GtkTreePath *path" parameter you get from the row-activated callback.
https://developer.gnome.org/gtk3/stable/GtkTreeModel.html#gtk-tree-path-get-indices
I tried to do:
int column = gtk_tree_path_get_indices( column );
but got an error:
Can't convert GtkTreeViewColumjn to GtkTreePath
The "row-activated" callback is defined as:
void user_function(GtkTreeView *tree_view, GtkTreePath *path,
GtkTreeViewColumn *column, gpointer user_data);
And so the types are unrelated.
What am I doling wrong?
Thank you.

Hi, ALL,
For the GtkTreeView there is a "row-activated" signal:
https://developer.gnome.org/gtk3/stable/GtkTreeView.html#GtkTreeView-row-activated.
That function receives as a parameter
column the GtkTreeViewColumn in which the activation occurred.
The problem is (at least as I see it) is that it is not a simple integer
for the column number.
Is there a simple way to get a column number on which I activated
the row from this signal?
Thank you.
