Hi everybody,

i can't get treeview value of my liststore.i've a result but the result is similar if i click on the first value or last value.

Code:
#include "fileviewer.h"



int main(int argc,char *argv[])
{         
   gtk_init(&argc,&argv);

   t_widget *p_widget = init_gtkWidget();
   
   interface();
   free_gtkWidget();

   return EXIT_SUCCESS;
   
}

t_widget *init_gtkWidget()
{
   t_widget *p_widget = malloc(sizeof(t_widget));
   
   if(p_widget) {
      
      p_widget->pMainWindow = gtk_window_new(GTK_WINDOW_TOPLEVEL);;
      p_widget->pModel = NULL;
      p_widget->pTreeView =  gtk_tree_view_new();
      p_widget->pButton_def = gtk_button_new_with_label("Definir");
      p_widget->pButton_quitter = gtk_button_new_with_label("Quitter");;
      p_widget->pFixed = gtk_fixed_new();
      p_widget->pCombo_box = gtk_combo_box_new_with_entry();
      p_widget->pScrollBar = gtk_scrolled_window_new(NULL,NULL);   
      p_widget->pRenderer = gtk_cell_renderer_text_new();
      p_widget->pListe= NULL;
      p_widget->test= NULL;
      p_widget->valeur = 10;
   
      
   }
   return p_widget;
}


void interface()
{   
   t_widget *p_widget;

        /* Combo Box */
      gtk_fixed_put(GTK_FIXED(p_widget->pFixed), p_widget->pCombo_box, 25, 50);
   gtk_widget_set_size_request(p_widget->pCombo_box, 250,10);
   
        /* Bouton Definir */
   gtk_fixed_put(GTK_FIXED(p_widget->pFixed), p_widget->pButton_def , 25, 100);
   gtk_widget_set_size_request(p_widget->pButton_def, 100, 20);
   
   /* Bouton Quitter */
   gtk_fixed_put(GTK_FIXED(p_widget->pFixed), p_widget->pButton_quitter, 150, 100);

In python I have something that looks like this, you will have to convert it to C or whatever.
Code:
    def get_selection(self):
        """Get selected"""
        selection = self.treeview.get_selection()
        model, paths = selection.get_selected_rows()
        return model, paths

    def treeview_get_selected(self, data=None):
        """Get selected treeview item"""
        model, paths = self.get_selection()
        for path in paths:
            lexiter = model.get_iter(path)
            value = model.get_value(lexiter, 0)
            return value
            #print '(%s, %s)' % (path, value)
        return
