How to integrate CPPToolTip in your application

To integrate PPToolTip control in your application you should add next files to your project:

Files	Description
PPTooltip.h PPTooltip.cpp	CPPTooltip class
PPHtmlDrawer.h PPHtmlDrawer.cpp	CPPHtmlDrawer class. It's need to drawing HTML string in tooltip body
PPDrawManager.h PPDrawManager.cpp	CPPDrawManager class is a set of methods to work with graphics.
CeXDib.h CeXDib.cpp	CCeXDib class thanks to Davide Pizzolato and Davide Calabro. This class use for extend background's effect.

Extend background effects by Davide Pizzolato and Davide Calabro become available if defined USE_SHADE:

in PPDrawManager.h
#define USE_SHADE

Create a CPPToolTip object

Include PPTooltip.h in the header file where you want to use the CPPToolTip window and create a member variable for the window:

CPPToolTip m_tooltip;

Now create the window. For dialog-based applications, in your OnInitDialog:

// Call the base-class method

CDialog::OnInitDialog();

// Create the CPPToolTip object

m_tooltip.Create(this);

Now call AddTool function to register a tool with the tool tip control, so that the information stored in the tool tip is displayed when the cursor is on the tool:

m_tooltip.AddTool(GetDlgItem(IDC_BUTTON1), _T(
 "Tooltip to the control IDC_BUTTON1"));

or for rectangle area

m_tooltip.AddTool(this, _T("Tooltip for rectangle area"), 
 CRect (100, 100, 200, 200));

Now you must add RelayEvent function call to pass a mouse message to a tooltip control for processing.

BOOL ... ::PreTranslateMessage(MSG* pMsg)
{
    m_tooltip.RelayEvent(pMsg); 
}

 

Using a tooltip with a toolbar

1. Create CPPToolTip object in the header CMainFrame

CPPToolTip m_tooltip;

2. In CMainFrame::OnCreate() call a AddToolBar method.

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    ...
    m_tooltip.Create(this);
    //Adds tooltip for toolbar

    m_tooltip.AddToolBar(&m_wndToolBar);
    return 0;
}

3. Add RelayEvent function call to pass a mouse message to a tooltip control for processing.

BOOL CMainFrame::PreTranslateMessage(MSG* pMsg)
{
    m_tooltip.RelayEvent(pMsg);
}

Extended string from resources

Notice, that the text for tooltips are automatically loaded from resources.
The string format was expanded with the third parameter, used for disabled items of the the menu and the toolbar.

Format string in resource: Parameter1\nParameter2\nParameter3

,where :

• Parameter1 - text for the normal menu items and status bar
• Parameter2 - text for the normal toolbar items
• Parameter3 - text for the disabled menu and toolbars items

Using a tooltip with a menu

1. Create CPPToolTip object in the header CMainFrame

CPPToolTip m_tooltip;

2. In CMainFrame::OnCreate() call a Create method.

m_tooltip.Create(this);

3. Uncomments a line to enable a work with menus.

in PPTooltip.h 
#define PPTOOLTIP_USE_MENU

4. Adds two handlers to CMainFrame.

void CMainFrame::OnMenuSelect(UINT nItemID, UINT nFlags, HMENU hSubMenu)
{
     m_tooltip.OnMenuSelect(nItemID, nFlags, hSubMenu);
     CFrameWnd::OnMenuSelect(nItemID, nFlags, hSubMenu);
}


void CMainFrame::OnEnterIdle(UINT nWhy, CWnd* pWho)
{
     m_tooltip.OnEnterIdle(nWhy, pWho);
}

5. Add RelayEvent function call to pass a mouse message to a tooltip control for processing.

BOOL CMainFrame::PreTranslateMessage(MSG* pMsg)
{
    m_tooltip.RelayEvent(pMsg); 
}

Remarks

This function enables or disables the ability to send notification messages to destination window from the control. If user enabled notify message passing from tooltip to owner class then tooltip object sends the UDM_TOOLTIP_DISPLAY notification before displaying. In a handler of this notify owner class can change any parameters of tooltip displaying. With UDM_TOOLTIP_DISPLAY notification NM_PPTOOLTIP_DISPLAY structure is transferred, contained all necessary information.

Structure NM_PPTOOLTIP_DISPLAY looks as follows:

typedef struct tagNM_PPTOOLTIP_DISPLAY
{
    NMHDR hdr;
	   HWND hwndTool;       //HWND of the window to display a tooltip

    LPPOINT pt;          //The current screen coordinates of 

                          //the tooltip's anchor

    PPTOOLTIP_INFO * ti; //The pointer to the PPTOOLTIP_INFO 

                          //structure which contains parameters for 

                          //displaying tooltip

} NM_PPTOOLTIP_DISPLAY;

Owner object should process notification messages to have the ability to change tooltip appearance and placement by changing approppriate members of this structure.

Here example:

Add next lines to header and implementation files accordingly.

afx_msg void NotifyDisplayTooltip(NMHDR * pNMHDR, LRESULT * result);

ON_NOTIFY (UDM_TOOLTIP_DISPLAY, NULL, NotifyDisplayTooltip)

and

void CParentDlg::NotifyDisplayTooltip(NMHDR * pNMHDR, 
 LRESULT * result)
{
    *result = 0;
	NM_PPTOOLTIP_DISPLAY * pNotify = 
     (NM_PPTOOLTIP_DISPLAY*)pNMHDR;
	
     switch (CWnd::FromHandle(pNotify->hwndTool)
      ->GetDlgCtrlID())
	{
    case IDC_BUTTON1:
        //Changes the tooltip's text

        pNotify->ti->sTooltip = _T("Dynamically 
            changed text for BUTTON1");
        break;
    case IDC_BUTTON2:
        //Changes background color of the tooltip as RED

        pNotify->ti->crBegin = RGB (255, 0, 0); 
        break;
    }

Shraddhan 10:25 19 Mar '09   I have a dialog with an area in it for which I would like a tool tip. Doing only this is no problem, but I also want to enclose the area in a group box. If I pass a pointer to the dialog window as the first argument to AddTool, the hWnd is not recognised so no tool tip is displayed. If I pass a pointer to the group box as the first parameter, the hWnd is recognised, but the mouse coordinates are transformed by an unnecessary call to ScreenToClient inside FindTool. These coordinates are now incorrect, so again no tool tip. How do I solve this?
