[Gtk-sharp-list] Disable TreeView Row

[Wolfgang Mauer]

Hi all,
yes it works.
and also it is usefull to implement a TreeCellDataFunc th make the entrys sensitive.

void tree_cell_data_func(TreeViewColumn tree_column, CellRenderer cell, TreeModel tree_model, TreeIter iter)
{
	object x = tree_model.GetValue(iter, 0);
	if (null != x)
	{
		if (.......)
		{
			cell.Sensitive = false;
		}
		else
		{
			cell.Sensitive = true;
		}
		((CellRendererText)cell).Text = x.ToString();
	}
}

/
Wolfgang
