Click here for larger image

The CSpinEdit is an alternative control for standard CSpinButtonCtrl, but has
new features: 

• Supports spinning data with mouse wheel
• Automatically increases data when pressing the upper button, but decreases if pressing the lower button
• The spinned data type can be integer , float or double
• You can specify the decimal digits
• If you provide valid extra-text parameter, the string will be displayed on the control on the left side of numeric data
• The SpinEdit uses inplaced edit control to edit spinned data

Usage

Follow these steps in order to use the CSpinEdit control.

1. Include the following files in your project

   seedit.h
   seedit.cpp
   spinedit.h
   spinedit.cpp
   

2. Add a Custom Control to dialog
3. Set the class to "SPINEDITCTRL"
4. Add a member variable after the line "//}}AFX_DATA" to the dialog class

   CSpinEdit m_SpinEdit;
   

5. Add the following weight line in the method "DoDataExchange "
   in the implementation file.

   void CSpinDlg::DoDataExchange(CDataExchange* pDX)
   {
    CDialog::DoDataExchange(pDX);
    //{{AFX_DATA_MAP(CSpinDlg)
    DDX_Radio(pDX, IDC_RADIOINT, m_nDataType);
    DDX_Text(pDX, IDC_EDITSTEP, m_dbStep);
    DDX_Text(pDX, IDC_EDITPOINT, m_bPos);
    DDX_Text(pDX, IDC_EDITMIN, m_dbMin);
    DDX_Text(pDX, IDC_EDITMAX, m_dbMax);
    DDX_Text(pDX, IDC_EDITEXTRATEXT, m_strExtraText);
    DDX_Check(pDX, IDC_CHECKTEXT, m_bNeedText);
    //}}AFX_DATA_MAP
    DDX_SpinEditControl(pDX, IDC_SPINEDIT, m_SpinEdit);
   }
   

6. The initialization and parameters setting of the control is like
   common controls.

Dynamically Creating a CSpinEdit in a View

1. Include the following files in your project:

   seedit.h
   seedit.cpp
   spinedit.h
   spinedit.cpp
   

2. Add a member variable to your view( suppose the view is CSpinEditCtrlView in the demo )

   CSpinEdit *m_pSpinEdit;
   

3. Initialize it in the view’s constructor

   m_pSpinEdit = NULL;

4. 4. Create the control in the menu command handler

   void CSpinEditCtrlView::OnSpinDynamic()
   {
    // TODO: Add your command handler code here
    if( m_pSpinEdit != NULL )return;
   
    m_pSpinEdit = new CSpinEdit;
   
    CRect rect(100,100,300,130);
   
    m_pSpinEdit->Create( this,
                            rect,
                            ID_SPINEDIT,
                            WS_VISIBLE );
   
    m_pSpinEdit->SetParams( SE_DOUBLE,
                               2, 0, 0, 0, 100, 0.01,
                               TRUE, "example" );
   }
   

5. You can access the value via

   double dbCurValue = m_pSpinEdit->GetCurValue();
   

   Unfortunately, you have to cast the result to integer type if you expect integer value.

6. Delete it in the view’s destructor:

   if( m_pSpinEdit != NULL )
    delete m_pSpinEdit;
