Re: Treeview with images problem

[Martyn Russell <ginxd btopenworld com>]

Ok I had this problem when I was trying to do the same thing.  The 
documentation is poor for it, and they it has been mensioned.  The way 
to do it is to create the two renderers and pack one at the start and 
the other at the end.  NOTE it is important to worry about the 3rd 
parameter (TRUE/FALSE) because if you don't the renderers data overlaps.

**** to create the columns ****

 GtkCellRenderer *renderer_text;
 GtkCellRenderer *renderer_image;
 GtkTreeViewColumn *column;

 /* cell renderer's */
 renderer_image = gtk_cell_renderer_pixbuf_new();
 renderer_text = gtk_cell_renderer_text_new();

 column = gtk_tree_view_column_new();

 /* COL_IMAGE */
 gtk_tree_view_column_pack_start(column,renderer_image,FALSE);
 gtk_tree_view_column_add_attribute(column,
                    renderer_image,
                    "pixbuf",COL_IMAGE); 

 /* COL_NAME */
 gtk_tree_view_column_pack_end(column,renderer_text,TRUE);
 gtk_tree_view_column_add_attribute(column,
                    renderer_text,
                    "text",COL_NAME);


 /* insert column */
 gtk_tree_view_insert_column(GTK_TREE_VIEW(treeview),column,-1);

 /* properties */
 gtk_tree_view_set_enable_search(GTK_TREE_VIEW(treeview),TRUE);
 gtk_tree_view_set_search_column(GTK_TREE_VIEW(treeview),COL_NAME);
 gtk_tree_view_set_rules_hint(GTK_TREE_VIEW(treeview), FALSE);
 gtk_tree_view_set_headers_visible(GTK_TREE_VIEW(treeview),FALSE);
 gtk_tree_view_set_headers_clickable(GTK_TREE_VIEW(treeview), FALSE);
 gtk_tree_view_columns_autosize(GTK_TREE_VIEW(treeview));
 gtk_tree_view_expand_all(GTK_TREE_VIEW(treeview));
