Edit Control with Icon and Background Text


This article presents an edit control that can display an icon and a prompt text on the background (when the edit control has no text). This is most suitable to indicate to the users that an edit control is used to input text that is used for a search.

The image below shows several such edit controls.

The same controls look like the following when text is entered.

Features of the edit control:

  • Displays an icon on the right side of the control
  • Displays a prompt text (only when the control has no text)
  • Changes the color of the prompt text
  • Changes the font of the prompt text


The class implementing this control is called CSymbolEdit and subclasses CEdit. (If you’re not familiar with subclassing, a method of customizing the behavior of a window, I suggest you read this article: “Demystifying Subclassing.”)

The public interface of the control is:

void SetSymbolIcon(HICON hIcon, BOOL redraw = TRUE);
void SetSymbolIcon(UINT id, BOOL redraw = TRUE);

void SetPromptText(CString text, BOOL redraw = TRUE);
void SetPromptText(LPCTSTR szText, BOOL redraw = TRUE);

void SetPromptTextColor(COLORREF color, BOOL redraw = TRUE);

void SetPromptFont(CFont& font, BOOL redraw = TRUE);
void SetPromptFont(const LOGFONT* lpLogFont, BOOL redraw = TRUE);

There are two overloads for SetSymbolIcon, one that takes an HICON, and one that takes the ID of a resource. The control is responsible for releasing the icon resource only when the second overload was used. If an HICON was passed, the client of the control must release this resource.

If SetPromptTextColor is not called and a prompt text was set, this prompt text is draw by default with the color RGB(127, 127, 127).

If SetPromptFont is not called and a prompt text was set, this text is drawn with Calibri in italics.

How to Use It in Your Code

  1. In your dialog class header, include “SymbolEdit.h”.

  2. Declare a variable of type CSymbolEdit.

    CSymbolEdit m_edit;
  3. Map it to the control in DoDataExchange:

    void CEditDemoDlg::DoDataExchange(CDataExchange* pDX)
    DDX_Control(pDX, IDC_EDIT, m_edit);
  4. Set the icon, text, color, or font (in OnInitDialog, for example).

    m_edit.SetSymbolIcon(IDI_SEARCH, FALSE);
    m_edit.SetPromptText(_T(“Find “), FALSE);
    m_edit.SetPromptTextColor(RGB(192, 192, 192));
