CWnd::OnGetDlgCode

Called for a control so the control can process arrow-key and TAB-key input itself.

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.
