Typically, you would use two cell renderers for this task. For example,
in a file browser, you might not have 1 column for the icon and another
for the filename, but instead you could pack the icon renderer AND
filename renderer into the column for a single column so that the
alignment works.
col = gtk_tree_view_column_new();
gtk_tree_view_column_set_title(col, Filename);
renderer = gtk_cell_renderer_pixbuf_new();
gtk_tree_view_column_pack_start(col, renderer, FALSE);
gtk_tree_view_column_set_attributes(col,
renderer,
pixbuf,
FILE_ICON,
NULL);
renderer = gtk_cell_renderer_text_new();
gtk_tree_view_column_pack_start(col, renderer, TRUE);
gtk_tree_view_column_set_attributes(col,
renderer,
text,
FILE_NAME,
NULL);
gtk_tree_view_append_column( GTK_TREE_VIEW
(panel-priv-tree_view), col);

Hi,
I'm trying to write a custom widget to represent some data in a way
similar to this image: http://www.threatofchaos.com/imagenes/hsl2.PNG
What I need is to nest items in a TreeView, but changing the set of
columns that are represented. I mean, I need to have
- Item 1
- Item 2
* SubItem 2.1
* SubItem 2.2
- Item 3
* SubItem 3.1
All Item 1, 2 and 3 would have the same set of columns. SubItems 2.1 and
2.2 would have another set of columns, and SubItem 3.1 another different
one.
I have been trying to use a combination of Expanders and TreeViews, but
I feel that it's very inefficient, and I haven't found the way to have
all the columns in the same set correctly aligned yet.
Other option I was considering was creating some kind of new Cell
Renderer that would include the SubItems. Is there any way to make a
renderer that spans multiple columns and with a widget inside it?
Thanks very much in advance,
Alejandro Serrano
