I had tried this unsuccessfully... That's why I asked.

	tree.SetNode(editid, tree.GetNode(editid).SetImage(CtrlImg::ImgEdit()));

E:\AriUppApps1\ideAris1\main.cpp(26) : error C2662: 'TreeCtrl::Node::SetImage' : cannot convert 'this' pointer from
'const TreeCtrl::Node' to 'TreeCtrl::Node &'

Quote:

Ah... Well, one of rare cases when C++ does not play well...

Try

TreeCtrl::Node n = tree.GetNode(editid);
n.SetImage(CtrlImg::ImgEdit());
tree.SetNode(editid, n);

Thinking about it, it would probably be better here to return Node value instead of constant reference... what do you think? (Constant reference is faster, however in this case it is very likely you are about to change the value in most cases).

It works this morning... I can't believe it didn't work yesterday Shocked

... Something magic. Maybe I was too tired and did a typo mistake once again somewhere. And I knew about that const... Smile

Anyway, thank you very much for confirming it because I was going mad and suspected bugs everywhere... Smile

And I couldn't understand the reason of not returning Node... but I have not much against const if it works... Laughing

Well, I have changed it to return value instead of reference... so no more confusion there Smile
