[gnome-love] Expanders in GtkTree* from GTK+ 2.0

[Thomas Broyer <tbroyer ltgt net>]

Hi,

According to Miguel's last mail, it seems gnome-love is really the place
for my question.

I'm currently learning the GTK+ 2.0 new API (from gtk+-1.3.5) and
particularly the GtkTree* part.

First, I create a GtkTreeStore and populate it with data. Then I create a
GtkTreeView with that model, and a GtkCellRendererText I use in three
GtkTreeViewColumn, which ones are appended to the view.
Well, as shown in the example of the gtk-doc, adding data to the tree.

Then I show all this stuff.

Here comes the question/problem: the tree expander arrows are always on the
first column, is there a way to have them in another column AND follow that
column when I drag&drop it?
I can't find any relevant function.

I found gtk_tree_view_set_expander_column (not documented) which allows to
specify the *visual* column where to draw the expander arrows, not the
*logical* column: when a drag&drop a column, the expanders don't follow it.
(and is this the expected behaviour or is this a bug?)

Think of a MUA or newsreader: tree is always shown in the subject column.

Tom.
