Re: Handling parent & child behaviour using tree view

["Saba Khan" <s_i_uk hotmail com>]

HI,
Thank you for prompt reply. I am using this code so please check it out.
But when it reach to the method gtk_tree_model_iter_parent(), it shows 
warning which is listed below.

GtkTreeModel *pModel = gtk_tree_view_get_model 
(GTK_TREE_VIEW(m_pFileTreeView));
g_signal_connect((gpointer) m_pRendererCheck, "toggled", G_CALLBACK 
(OnCellToggled), pModel);
void OnCellToggled(GtkCellRendererToggle *pCellRenderer, gchar *path, 
gpointer pUserData)
{
	GtkTreeModel *TreeModel = (GtkTreeModel *)pUserData;
	if (!TreeModel)
	{
		ASSERT(FALSE);
		return;
	}
	GtkTreeIter  iter, cSessionIter;
	GtkTreePath *TreePath = gtk_tree_path_new_from_string (path);
	gboolean bFixed;
	// Get toggled iter
	gtk_tree_model_get_iter (TreeModel, &iter, TreePath);
	gtk_tree_model_get (TreeModel, &iter, TRACK_TOOGLE_BOX_COL, &bFixed, -1);
	// Do something with the value
	bFixed = gtk_cell_renderer_toggle_get_active(pCellRenderer);
	if (bFixed)
		bFixed = FALSE;
	else
		bFixed = TRUE;
	if (gtk_tree_model_iter_parent(GTK_TREE_MODEL (TreeModel), &iter, 
&cSessionIter))
	{
		//gtk_tree_store_set (GTK_TREE_STORE (TreeModel), &cSessionIter,
                  column, bFixed, -1);
		if (gtk_tree_model_get_iter_first(GTK_TREE_MODEL (TreeModel), 
&cSessionIter))
		{

		}
	}
