private static bool UpdateGameInModel(PGNChessGame
game,
PGNChessGame
replace,
TreeModel
model)
{
TreeIter iter;
bool ret;
for (ret = model.GetIterFirst (out iter); ret;
ret = model.IterNext (ref iter))
{
PGNChessGame g =
(PGNChessGame) model.
GetValue (iter, 0);
if (g.Equals (game))
{
model.SetValue (iter, 0,
replace);
return true;
}

return false;
}示例3: IterPrev
//generally useful function... why not in model already?
private bool IterPrev(TreeModel model, ref TreeIter iter)
{
TreeIter prev, next;
if (!model.GetIterFirst (out prev))
return false;
do {
next = prev.Copy ();
if (!itemStore.IterNext (ref next))
return false;
//if next one on from prev is our iter
//then 'prev' is correct previous iter
if (next.Equals (iter)) {
iter = prev;
return true;
}
} while (itemStore.IterNext (ref prev));
return false;
