CSpinEdit that Displays Additional Text


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;

    return bResult;

  • Showing disabled control in grey....

    Hi

    Your control is just what I require for my program - thank you!

    But I need one bit of functionality not present in your class. If I disable the control:

    m_spinToleranace.EnableWindow(FALSE);

    Although it disables it so that it doesn't work, it doesn't dim the control and it looks confusing on my dialogue.

    Can you add this functionality for me?

    Thank you in advance.
