InkEdit Messages (Win32 Only)

The InkEdit control is a super class of the RichEdit Leave Site control. Every RichEdit Leave Site message is passed on, directly in most cases, and has exactly the same effect as in RichEdit Leave Site. This also applies to event notification messages.

Messages

[C++]

To send these messages, call the SendMessage function with the following parameters:

LRESULT SendMessage(
  HWND hWnd,      // handle to destination window
  UINT Msg,       // message
  WPARAM wParam,  // first message parameter
  LPARAM lParam   // second message parameter
);

The parent window of the InkEdit control receives event notification messages through the WM_NOTIFY message:

LRESULT CALLBACK WindowProc(
    HWND hWnd,                // handle to window
    UINT uMsg,                // WM_NOTIFY
    WPARAM wParam,        // InkEdit control identifier
    LPARAM lParam            // see documentation for notification messages
);
