c - GTKButton with GtkListStore -

i tried add gtkbutton gtkliststore edit data in each row... button doesn't appear, , error message : "glib-gobject-warning **: unable set property text' of typegchararray' value of type `gtkbutton'". here code :

#include <gtk/gtk.h> gtktreemodel * create_and_fill_model() { gtkliststore  *store; gtktreeiter    iter; store = gtk_list_store_new (9,                             g_type_string,                             g_type_string,                             g_type_string,                             g_type_string,                             g_type_string,                             g_type_string,                             g_type_uint,                             g_type_float,                             gtk_type_button); gtk_list_store_append (store, &iter); gtk_list_store_set (store, &iter,                     0, "a5525654",                     1, "dfffccn",                     2, "doe",                     3, "john",                     4, "m",                     5, "casablanca",                     6, 2014,                     7, 18.22,                     8,gtk_button(gtk_button_new_with_label("edit")),                     -1); return gtk_tree_model (store); } gtkwidget * create_view_and_model() { gtkcellrenderer     *renderer; gtktreemodel        *model; gtkwidget           *view;  view = gtk_tree_view_new (); char colonne[9][16] = {     "cin",     "cne",     "nom",     "prenom",     "sexe",     "etablissement",     "annee obt",     "note gener",     "edit" }; int i; for(i=0; i<9; i++) {     renderer = gtk_cell_renderer_text_new ();     gtk_tree_view_insert_column_with_attributes (gtk_tree_view (view),             -1,             colonne[i],             renderer,             "text", i,             null); } model = create_and_fill_model (); gtk_tree_view_set_model (gtk_tree_view (view), model); g_object_unref (model); return view; } int main (int argc, char **argv) { gtkwidget *window; gtkwidget *view; gtk_init (&argc, &argv); window = gtk_window_new (gtk_window_toplevel); g_signal_connect (window, "delete_event", gtk_main_quit, null); view = create_view_and_model (); gtk_container_add (gtk_container (window), view); gtk_widget_show_all (window); gtk_main (); return 0; } 

your implementation of placing button in tree view cannot work written. creating text renderer columns, , text renderer cannot draw gtk button. (you error while setting text property on renderer based on button-typed column in model.)

one simple way of placing button in tree view putting clickable image in cell, shown this answer.
