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

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;
