When the user right clicks on an item in my MFC apps tree control I need it to bring up a context menu. All i need to know is how to find what item the user right clicked on. I cant just add a NM_RCLICK message because the function doesnt know what item was clicked (in fact you dont have to rClick on an item at all- anywhere in the window will do which is not what I want). I just want the user to right click on an item in the tree control and then a menu appears. Can anyone help me with this? Thanks for any help.

Say you have a CTreeCtrl in a dialog, all u have to do is add a NM_RCLICK message to the tree control and in the ''click'' method you find out which item the user clicked. Like this:

void CMyDlg::OnRclickProperty(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*)pNMHDR;
pNMTreeView->itemNew; <== Here u go! =)

itemNew is a TVITEM and is identical to TV_ITEM (just a different naming convention). Based on this u should be able to get all the info u need to get the contextmenu working.

Thanks for the reply Talbot, that is what I tried before but the itemNew was never a valid item. Its probably something else wrong in my code but it just wouldnt work that way.

However I found a way around it by catching RButtonDown and then doing a CTreeCtrl::HitTest with the coords passed into OnRButtonDown().

Id imagine this is really not a good way of doing this but it works.

Thanks again for the reply

Maybe you should consider simply handling WM_CONTEXTMENU for the menu, though you will still find it necessary to use the hit test to determine the item I believe.

Hey thanks felisandria thats a really good idea. I''ll have a go at that, I think it will take a step out of my code. Thanks again.
