Can comeone please explain to me why this seems to not work as advertised?
I have seen countless examples which go to great lengths to implement
what I want to do and which seems as if it should be quite simple.

I have multiple IPictEditor controls which are a simple LED box
on a dialog.

I have created and added a CToolTipCtrl for each one. All of this works
perfectly - the tooltip pops up just like I want it to.

Periodically I update the tooltip text using UpdateTipText(). No
problem there.

What I would like to be able to do is update the text when the user moves
the cursor over the tooltip area.

The documentation for the CToolTipCtrl class seems to indicate that this
should be as simple as:

1. Override OnToolHitTest() ie. INT_PTR CMon::OnToolHitTest(CPoint point,
TOOLINFO* pTI) const


INT_PTR CMon::OnToolHitTest(CPoint point, TOOLINFO* pTI) const
{

BOOL res;
CToolInfo m_ToolInfo;

TRACE("\n Point %d, %d Hit",point.x,point.y);

for (int i=0; i<IBS_MAXIMUM_POL_COUNT; i++)
{
// Get the ToolInfo about this Tool
if (m_POLErrorInfo[i].GetToolInfo(m_ToolInfo, GetDlgItem(IDC_RUN_0+i)))
{
if (m_POLErrorInfo[i].HitTest(GetDlgItem(IDC_RUN_0+i), point,
(LPTOOLINFO)&m_ToolInfo))
{
TRACE("\n Tooltip for POL %d is hit",i);
// I should be able to call UpdateTipText() to update my text...
}

}

}
return Dialog_Brush_Base::OnToolHitTest(point, pTI);
}



The HitTest always returns true, regardless of where the cursor is.
GetToolInfo() correctly returns info about my tooltip.

Did you specify a problem in this post? I read the entire thing but did see
a question!
Is the question why m_POLErrorInfo[i].HitTest() return TRUE all the time?
That all depends on what your AddTool method looks like?

Why do you have an array of CToolTipCtrls? You should have one pre dialog
and add multiple tools (control) to it using AddTool. After you do that
CToolTipCtrl::HitTest will return the control id of the control under the
mouse.

As far as your OnToolHitTest goes you should return pTI->uId if you want to
change the tooltip or -1 if you don't. (The doc is wrong on that you have to
return 1).

I have an array of 32 tooltip controls because I have 32 LEDs. The tooltip
for a given LED is not
always enabled, hence Activate() must apply only to a given control/tooltip.

The question is how can I update the text when the cursor is placed over the
control such that the
tooltip pops up current information?

Thanks!

If I were you I would use the TTN_NEEDTEXT message. With that said you will
need to get rid of all the CToolTipCtrls that you currently create. Here
all you have to do is call EnableToolTips(TRUE) in your dialog
OnInitDialog().. Then you catch the TTN_NEEDTEXT notify message like this

BEGIN_MESSAGE_MAP(CMyDialog, CDialog)
ON_NOTIFY_EX( TTN_NEEDTEXT, 0, OnToolTipNotify)
END_MESSAGE_MAP()

BOOL CMyDialog::OnToolTipNotify( UINT id, NMHDR * pNMHDR, LRESULT *
pResult )
{
TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR;
UINT nID =pNMHDR->idFrom;
if (pTTT->uFlags & TTF_IDISHWND)
{
// idFrom is actually the HWND of the tool
nID = ::GetDlgCtrlID((HWND)nID);
pTTT->hinst = AfxGetResourceHandle();
switch (nID)
{
case IDOK : pTTT->lpszText = "OK Button";
return TRUE;
case IDCANCEL : pTTT->lpszText = "Cancel Button";
return TRUE;
default: return FALSE;
}
}
return FALSE;

}

This will work, but only for Controls like a button.
I am using images via IPictEditor. OnToolTipNotify() doesn't seem to get
called for Static type 'controls'.

I have seen several somewhat cumbersome solutions ranging from Subclassing
to a bunch of code added to
PreTranslateMessage(). Neither seems very attractive.

Is there a simpler solution?

Thank you!
