EIntOverflow

[jcplu]

Hello,
I sometimes get EIntOverflow with
function TTreeNodeHelper.GetCheckState: TCheckState;
because State = 0, so Result = -1

An idea ?

Do you have steps to reproduce the issue in a consistent way?

I think that StateIndex and CheckState are not synchronized so I need to initialize StateIndex and CheckState.

[jcplu]

TreeView_SetItemState(TreeView.Handle, Self.ItemId, State, TVIS_STATEIMAGEMASK) returns value > 0
TreeView_GetItemState(TreeView.Handle, Self.ItemId, TVIS_STATEIMAGEMASK) returns value = 0

[jcplu]

wNode.CheckState := csUnchecked;
wNode.StateIndex := 0;
KO

wNode.StateIndex := 0;
wNode.CheckState := csUnchecked;
OK

It seems that StateIndex assignation changes the value of CheckState.
