Hi;

The last few hours I tried in vain to create Office2007 style tooltips in a CXTTreeCtrl derived class to show detailed infos about tree items. I searched the forum and I also looked at the samples provided with the 11.1.0 release of the toolkit but with no success.

What am I doing:

1. Insert a member of type CXTPTooltipContext into CXTTreeCtrl class

2. Overwrite OnWndMsg and call tipContext.FilterTooltipMessage()

3. Overwrite OnToolHitTest() and fill in the TOOLINFO as seen in different forum posts:

...
pTI->hwnd = m_hWnd; // handle of tree control
pTI->uId = (UINT_PTR)m_hWnd;
pTI->uFlags |= TTF_IDISHWND;
pTI->lpszText = LPSTR_TEXTCALLBACK;
pTI->uFlags |= TTF_NOTBUTTON|TTF_CENTERTIP;
return 1;
...

4. ?? (I tried to catch TTN_NEEDTEXTA/TTN_NEEDTEXTW in a ON_NOTIFY_REFLECT message handler. But this never gets called!

So where's my fault? Any ideas?

Many thanks in advance...
