Tracking Tooltips!

I think, you forgot to mention the problem...

Well, its always good to have as much detail as possible & who knows someone might be running lunix and still browsing VC forum ;). Anyways, i have looked at the project attached, i am not sure why you are setting the ToolRect to 0 or null when send TTM_ADDTOOL. The way you should do is to calulate the Rect of the rectangle for which you want to display the ToolTip, and set this calculated Rect when you send TTM_ADDTOOL to the Tooltip. And later on if the rect changes in size or location, use TTM_ADJUSTRECT to let Tooltip know the new rect. To hide ToolTip use TTM_POP and show it again use TTM_ACTIVATE .
With these messages you should be able to do what you want. Let me know if you need any more info.

Found something else in your code :). Why ru sending message to ToolTip on mousemove?? I suggest to do something like when do TTM_ADDTOOL
instead of TTF_TRACK use TTF_SUBCLASS. And remove the sendMessage TTM_TRACKPOSITION from OnMouseMove.
Hope this helps,

Try creating the window like MSDN does...

hwndTT = CreateWindowEx(WS_EX_TOPMOST,
TOOLTIPS_CLASS,
NULL,
WS_POPUP | TTS_NOPREFIX | TTS_ALWAYSTIP,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
hwnd,
NULL,
ghThisInstance,
NULL
);

Notice the WS_EX_TOPMOST style as the first param. Secondly when you add tool via TTM_ADDTOOL, get the client rect ( like ::GetClientRect(m_hWnd, &ti.rect); )of the whole dialog and set that Rect to ADDTOOL message. Also try removing the TTF_IDISHWND and supply some number like 123 for ... ti.uId = (UINT)123; . Lets see what happens...
Hope this helps,

Prabakaran, AshwinRao was asking for tracking toolbars.

You should not handle tips text in OnNotify override. You do not perform any check for notification code, nor for control that sends notification message. It can cause disaster.

It should be done in TTN_NEEDTEXT(A/W) handler and only if you have LPSTR_TEXTCALLBACK specified as text.
See your modified project.

Also project showing you hw to use native CWnd tooltips and how you can use CToolTipCtrl class; I did not write code to hide tooltips in the last one.
It is shown how it can be done in the others.

Thank you John.
Actually I misunderstood the problem(as it is not clearly mentioned in the previous thread). Anyway it is really good that problem is solved.
