TreeView + Popup menu

A while ago I got this tree view working just fine, but now I want to add a popup menu to it, and there's a problem. At first, I though handling the WM_RBUTTONDOWN message would work, but the tree view, not the parent window, receives mouse input, so I don't ever receive this message.

Then I thought, oh yeah I'll handle the NM_RCLICK notification, which works fine except I also need to somehow position the popup menu right next to the mouse, and NM_RCLICK apparently doesn't include the cursor position. So I've got:

Code:

case WM_NOTIFY: //handle treeview messages
    {
      if(wParam==ID_BROWSE_TREE)
      {
        LPNMHDR nm = (LPNMHDR)lParam;
        switch (nm->code)
        {
          case NM_RCLICK:
          {
            static HMENU hMenu = LoadMenu(GetModuleHandle(NULL),MAKEINTRESOURCE(IDR_MENU2));
            if (!hMenu)
           {
             MessageBox(NULL,"Unable to load popup menu!","Error",MB_OK);
             return;
           }
           TrackPopupMenuEx(GetSubMenu(hMenu,0),TPM_LEFTALIGN|TPM_TOPALIGN|TPM_LEFTBUTTON,0,0,hTree,NULL); //how do I get these two args?
          }
          break;

Any ideas on how I should/can do popup menus for a tree view?

Maybe GetMessagePos would work.

Ah parfait!

And here I am looking through the mouse input functions for a solution

Also, look into the WM_CONTEXTMENU notification.

That sounds like slightly better solution, but I just encountered another problem which I doubt it will fix. When you right click an item in the tree view, apparently it doesn't select it, instead it just highlights the item. So now I can't find any way to get a handle to the item that a user right clicks (unless they left-click first). Another simple solution please

Look into TreeView_HitTest. What I did a while ago was catch the NM_RCLICK message, retrieve the mouse position (GetCursorPos), convert to local coordinates (ScreenToClient) then call TreeView_HitTest with the proper parameters to retrieve the treeview item at that location (or NULL if none exists).

Send the TVM_HITTEST message to see what node (if any) is at the specified coordinates.

Hm well I tried TreeView_HitTest, but I just realized I was using the wrong cursor position (when I click the popup menu item). I'll try doing things a little differently and see I that works...

Thanks magos now it seems to be working perfectly (stay tuned for further problems )

I use the right click as a selection button as well and then fire off the right click menu for that item. Ran into the same problem as you in that the right mouse button does not select the item it's over.
