Introduction

This is a CDialog derived window, which resembles the tool tip that pop-ups with function parameters in Visual Studio IDE. The control allows to display a function definition with it's parameters and mark the current parameter in bold font.

Usage

1. Add a dialog resource to your project. Make sure to set the following for this dialog:

   Style = popup. 
   Border = None.
   No TitleBar

2. Add the dialog as a member to your application's main window.
3. Call create for the dialog while passing pointer to the window that the tool tip belongs to: m_intelliToolTip.Create(pParentWnd).
4. Add a function definition:

   BOOL CIntelliTipDemoDlg::OnInitDialog()
   {
    CDialog::OnInitDialog();
   
    // Set the icon for this dialog.  The framework does this automatically
    //  when the application's main window is not a dialog
    SetIcon(m_hIcon, TRUE);   // Set big icon
    SetIcon(m_hIcon, FALSE);  // Set small icon
    
    // TODO: Add extra initialization here
    m_tip.Create(this);
    CStringArray params;
    params.Add("Param 1");
    params.Add("Param 2");
    params.Add("Param 3");
    params.Add("Param 4");
    params.Add("Param 5");
    m_tip.SetFunction("SomeFunction",params);
    m_tip.SetCurParam(3);
    return TRUE;  // return TRUE  unless you set the focus to a control
   }

When you need to show the tool tip, call CIntelliTip::Show() or CIntelliTip::Hide() to hide it. To set the position, call CIntelliTip::SetCursorPoint(cursorPoint). Example:

void CIntelliTipDemoDlg::OnButton1() 
{
 // TODO: Add your control notification handler code here
 CPoint pt;
 GetCursorPos(&pt);
 ScreenToClient(&pt);
 m_tip.SetCursorPoint(pt);
 m_tip.Show();
}
