CWnd::OnGetDlgCode
Called for a control so the control can process arrow-key and TAB-key input itself.
afx_msg UINT OnGetDlgCode( );
Возвращаемое значение
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.
Заметки
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.
