Re: Change GtkTreeViewColumn header background color

[user2108 <chaitra213 gmail com>]

Hey,
I'm trying this from a very long time and I seriously need help. 
I followed the procedure as you said but I'm still not able to change the
color of the treeview column header as it is declared in GtkTreeViewColumn.
It throws an error saying assertion failed.
Is there any other way to get the headers color changed? I really need this
to get working and seems like I tried almost every method possible and
nothing seems to be working.
GtkTreeViewColumn   *col;
col = gtk_tree_view_column_new_with_attributes("First_Column",
                                                   renderer,
                                                   "text", COL_ONE,
                                                   NULL);

GtkWidget *title1;
title1 = gtk_label_new(gtk_tree_view_column_get_title(col));
   gtk_widget_show(title1);
   gtk_tree_view_column_set_widget(col, title1);
GtkWidget *sample = gtk_tree_view_column_get_widget(col);
GtkWidget *just =
gtk_widget_get_parent(gtk_widget_get_parent(gtk_widget_get_parent(sample)));
   gtk_widget_modify_bg (just, GTK_STATE_NORMAL, &blue_button);
 gtk_tree_view_append_column(GTK_TREE_VIEW(treeview),
                                col);
