CWnd::OnGetDlgCode 

afx_msg UINT OnGetDlgCode( );

Return Value

One or more of the following values, indicating which type of input the application processes:

• DLGC_BUTTON   Button (generic).
  
  
• DLGC_DEFPUSHBUTTON   Default pushbutton.
  
  
• DLGC_HASSETSEL   EM_SETSEL messages.
  
  
• DLGC_UNDEFPUSHBUTTON   No default pushbutton processing. (An application can use this flag with DLGC_BUTTON to indicate that it processes button input but relies on the system for default pushbutton processing.)
  
  
• DLGC_RADIOBUTTON   Radio button.
  
  
• DLGC_STATIC   Static control.
  
  
• DLGC_WANTALLKEYS   All keyboard input.
  
  
• DLGC_WANTARROWS   Arrow keys.
  
  
• DLGC_WANTCHARS   WM_CHAR messages.
  
  
• DLGC_WANTMESSAGE   All keyboard input. The application passes this message on to the control.
  
  
• DLGC_WANTTAB   TAB key.

Remarks

Normally, Windows handles all arrow-key and TAB-key input to a CWnd control. By overriding OnGetDlgCode, a CWnd control can choose a particular type of input to process itself.

The default OnGetDlgCode functions for the predefined control classes return a code appropriate for each class.
