Unable to display RTF tooltips greater 80 chars

   Hi; 
I found a serious problem with CXTPToolTipContextToolTip::GetToolText() in conjunction with RTF tooltip windows - I didn't check it with the other tooltip types.
I tried to assign a longer RTF text to the tooltip window in the TTN_NEEDTEXT message handler by setting the lpszText member of the NMTTDISPINFO structure, but no tooltip window ever appeared. So after hours of debugging I broke down the problem to the CXTPToolTipContextToolTip::GetToolText() function. This function only takes the szText member of the NMTTDISPINFO structure to get the text. This is not according to the MS documentation about TTN_NEEDTEXT messages.

Since the GetToolText() function is not virtual, I'm unable to fix it without changing the code. Perhaps the guys at codejock will take this into account while working on the next maintenance release.

	Hello, Thanks, please patch sources now: tt.szText[0] = _T('\0'); tt.lpszText = tt.szText; GetOwner()->SendMessage(WM_NOTIFY, id, (LPARAM)&tt); lpToolInfo->strCaption = tt.lpszText; Same changes will be done for 11.2 release. Thank you

	In XTPToolTipContext.cpp. Replace whole method: CString CXTPToolTipContextToolTip::GetToolText(TOOLITEM* lpToolInfo) { if (lpToolInfo->bAutoCaption) { UINT_PTR id = lpToolInfo->uId; TOOLTIPTEXT tt = {0}; tt.hdr.hwndFrom = m_hWnd; tt.hdr.idFrom = lpToolInfo->uId; tt.hdr.code = TTN_NEEDTEXT; tt.uFlags = lpToolInfo->uFlags; tt.hinst = NULL; tt.szText[0] = _T('\0'); tt.lpszText = tt.szText; GetOwner()->SendMessage(WM_NOTIFY, id, (LPARAM)&tt); lpToolInfo->strCaption = tt.lpszText; if ((m_pContext->GetControlStyle() & TTS_NOPREFIX) == 0) { CXTPDrawHelpers::StripMnemonics(lpToolInfo->strCaption); } lpToolInfo->bAutoCaption = FALSE; } return lpToolInfo->strCaption; }
