CWnd::OnRawInput

  • Article

The framework calls this member function when the current window gets raw input.

afx_msg void OnRawInput(
    UINT nInputCode,
    HRAWINPUT hRawInput
);

Parameters

Parameter

Description

[in] nInputCode

Input code that indicates whether the input occurred while the application was in the foreground or not. In either case, the application must call CWnd::DefWindowProc so the system can perform cleanup.

This parameter can be one of the following values:

  • RIM_INPUT - Input occurred while the application was in the foreground.

  • RIM_INPUTSINK - Input occurred while the application was not in the foreground.

[in] hRawInput

Handle to a RAWINPUT structure that contains the raw input from the device.

Remarks

This method receives the WM_INPUT notification, which is described in the Windows SDK.

Note

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.

Requirements

Header: afxwin.h
