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();
}
}
