A tab-like sheet control







Download Source Code and Examples


To add the sheet control to CChildFrame in a MDI application:

  1. add a new member CSheetsWnd m_wndSheets to CChildFrame class.
  2. override CChildFrame::OnCreateClient, and inside the function call m_wndSheets.Attach(this). From this moment all child windows from CChildFrame are put in sheet the contol, each view with one page.

To add the sheet control to a CDialog:

  1. add a new member CSheetsWnd m_wndSheets to your dialog class.
  2. create n dialogs in resource editor, each with the WS_CHILD style.
  3. declare n dialog members in you dialog. One of these dialogs must be created with WS_VISIBLE style.
  4. overwrite OnInitDialog in your dialog class, and add m_wndSheets.Attach(this).
  5. call the Create function for each dialog declared as a member variable. (m_dlg1.Create(IDD_DIALOG1, this));

Suppose that your dialog contains one button IDOK and a button IDCANCEL. These buttons are children of your dialog. To eliminate the buttons from the pages sheet control you must derive a new class CSheetsDialog, and overwrite GetFirstView(), GetNextView() virtual functions from CSheetsWndas shown below. Of course, the variable type of m_wndSheets must be changed to the new class CSheetDialog.

The class CSheetsWnd could be easily extended with more features. I will try to put more features to this class.

// Declare this struct for store a set of ID's control. 
struct SCtrlID 
{ 
	CMap m_mapCtrlIDs; 
	SCtrlID() 
	{ 
		m_mapCtrlIDs[IDOK] = TRUE; 
		m_mapCtrlIDs[IDCANCEL] = TRUE; 
	}; 

	// Check if ID is in map or not. 
	BOOL Is(UINT id) 
	{ 
	BOOL bValue = TRUE; 
	return m_mapCtrlIDs.Lookup(id, bValue); 
	} 
 }; 

 // class CSheetsDialog header 
 class CSheetsDialog : public CSheetsWnd 
 { 
 public: 
	 CSheetsDialog(); 
	virtual ~CSheetsDialog(); 
	virtual CWnd* GetNextView(); 
	virtual CWnd* GetFirstView(); 

 private: 
	CWnd* GetNextViewValid(CWnd* pWnd); 
	static SCtrlID m_ctrlID; 
 }; 

 // class CSheetsDialog implementation 
 SCtrlID CSheetsDialog::m_ctrlID; 

 CSheetsDialog::CSheetsDialog() 
 { 
 } 

 CSheetsDialog::~CSheetsDialog() 
 { 
 } 

 CWnd* CSheetsDialog::GetFirstView() 
 { 
	return GetNextViewValid(CSheetsWnd::GetFirstView()); 
 } 

 CWnd* CSheetsDialog::GetNextView() 
 { 
	return GetNextViewValid(CSheetsWnd::GetNextView());; 
 } 

 // Scan if ID of pWnd is not in IDOK or IDCANCEL 
 CWnd* CSheetsDialog::GetNextViewValid(CWnd * pWnd) 
 { 
	while (pWnd && (m_ctrlID.Is(pWnd->GetDlgCtrlID()))) 
		pWnd = CSheetsWnd::GetNextView(); 
	return pWnd; 
 }
