Thank you for your help but it doesn't work -> any idea?
I use toolkit version 13.4. My class is derived form CUIXTreeCtrl which is based on CXTTreeCtrl.
here is my code:
//-----------------------------------------------------------------------------
int CUIActiveUsersTreeCtrl::OnCreate(LPCREATESTRUCT lpCreateStruct)
//-----------------------------------------------------------------------------
{
if (CUIXTreeCtrl::OnCreate(lpCreateStruct) == -1)
return -1;
// Create the image list used by the tree control.
if ( !m_imageList.Create( 16, 16, ILC_COLOR24 | ILC_MASK, 1, 1 ) )
{
TRACE0("Failed to create image list.\n");
return -1;
}
// load the tree images bitmap and add it to the image list.
m_bitmap.LoadBitmap( IDB_IMGLIST_VIEW );
m_imageList.Add(&m_bitmap, RGB(255,0,255));
// Set the image list for the tree control.
SetImageList( &m_imageList, TVSIL_NORMAL );
m_TTContext.SetStyle(xtpToolTipMarkup);
m_TTContext.ShowTitleAndDescription(TRUE);
SetToolTips(NULL);
return 0;
}
BOOL CUIActiveUsersTreeCtrl::PreCreateWindow(CREATESTRUCT& cs)
{
if ( !CUIXTreeCtrl::PreCreateWindow( cs ) )
return FALSE;
// Set the style for the tree control.
cs.style |= TVS_DISABLEDRAGDROP;
cs.style &= ~TVS_HASLINES;
cs.style &= ~TVS_LINESATROOT;
cs.style &= ~TVS_HASBUTTONS;
// If non-xp mode, add a client edge border to the tree.
if (!xtAfxData.bXPMode)
{
cs.dwExStyle |= WS_EX_CLIENTEDGE;
}
cs.style |= TVS_NOTOOLTIPS;
return TRUE;
}
CString CreateMarkupTool(LPCTSTR strCaption, LPCTSTR strDesc)
{
CString strHTML;
strHTML.Format(
_T("<StackPanel Margin='1' MaxWidth='200'>")
_T("<TextBlock Padding='1, 3, 1, 3' FontWeight='Bold'>%s</TextBlock>")
_T("<TextBlock Padding='9, 6, 30, 7' TextWrapping='Wrap'>%s</TextBlock>")
_T("<Border Height='1' Background='#9ebbdd' />")
_T("<Border Height='1' Background='White' />")
_T("</StackPanel>"),
strCaption, strDesc);
return strHTML;
}
INT_PTR CUIActiveUsersTreeCtrl::OnToolHitTest(CPoint point, TOOLINFO* pTI) const
{
// check child windows first by calling CControlBar
INT_PTR nHit = CWnd::OnToolHitTest(point, pTI);
if (nHit != -1)
return nHit;
HTREEITEM hTreeItem = GetItemFromPoint(point); // this is yust a helper to get item under cursor
if(hTreeItem)
{
nHit = (INT_PTR) hTreeItem;
m_TTContext.FillInToolInfo(pTI, GetSafeHwnd(), CRect(point, CSize(100, 100) ), nHit, CreateMarkupTool(_T("XXX Test"), _T("YYY TEST2")));
return nHit;
}
return -1;
}
void CUIActiveUsersTreeCtrl::RelayEvent(UINT message, WPARAM wParam, LPARAM lParam)
{
MSG msg;
msg.hwnd= m_hWnd;
msg.message= message;
msg.wParam= wParam;
msg.lParam= lParam;
POINT pt;
pt.x = LOWORD (lParam);
pt.y = HIWORD (lParam);
ClientToScreen(&pt);
msg.time= clock();
msg.pt.x= pt.x;
msg.pt.y= pt.y;
m_TTContext.FilterToolTipMessage(this, &msg);
}
BOOL CUIActiveUsersTreeCtrl::OnWndMsg(UINT message, WPARAM wParam, LPARAM lParam, LRESULT* pResult)
{
//m_TTContext.FilterToolTipMessage(this, message, wParam, lParam);
if (message == WM_MOUSEMOVE)
RelayEvent(message, wParam, lParam);
return CUIXTreeCtrl::OnWndMsg(message, wParam, lParam, pResult);
}

Ok it works now :-)
Changed the code in on ToolHitTest
...
HTREEITEM hTreeItem = HitTest(point, &nFlags); // GetItemFromPoint(point);
if(pTI && hTreeItem)
{
nHit = reinterpret_cast<INT_PTR>(hTreeItem);
...
Once again - thank you for your help!
