CWnd::OnEnterIdle

The framework calls this member function to inform an application's main window procedure that a modal dialog box or a menu is entering an idle state.

afx_msg void OnEnterIdle( 
   UINT nWhy, 
   CWnd* pWho  
);

nWhy

Specifies whether the message is the result of a dialog box or a menu being displayed. This parameter can be one of the following values:

  • MSGF_DIALOGBOX   The system is idle because a dialog box is being displayed.

  • MSGF_MENU   The system is idle because a menu is being displayed.

pWho

Specifies a pointer to the dialog box (if nWhy is MSGF_DIALOGBOX), or the window that contains the displayed menu (if nWhy is MSGF_MENU). This pointer may be temporary and should not be stored for later use.

A modal dialog box or menu enters an idle state when no messages are waiting in its queue after it has processed one or more previous messages.

NoteNote:

This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
