Members

cbSize

Type: UINT

Required. The size of the structure, in bytes. Set this parameter to sizeof(READERMODE) before you call DoReaderMode.

hwnd

Type: HWND

Required. The handle of the window to be used for reader mode.

fFlags

Type: DWORD

Flags customizing the functionality of the reader mode window. This parameter can be 0; otherwise, one or more of the following values.

Value	Meaning
RMF_ZEROCURSOR 0x01	Sets the cursor in the center of the area specified in prc. If this flag is not specified, the cursor position remains unchanged.
RMF_VERTICALONLY 0x02	Allows only vertical scrolling.
RMF_HORIZONTALONLY 0x04	Allows only horizontal scrolling.

prc

Type: LPRECT

A pointer to a RECT structure that specifies the scrolling area in the reader mode window. If this member is NULL, then the entire window is used as the scrolling area.

pfnScroll

Type: PFNREADERSCROLL

A pointer to an application-defined ReaderScroll callback function used to notify the application that the window needs to be scrolled in a particular direction.

fFlags

Type: PFNREADERTRANSLATEDISPATCH

A pointer to an application-defined TranslateDispatch callback function used to get first notification of any messages sent to the reader mode window.

lParam

Type: LPARAM

Additional information as needed by the application, read by the caller in the ReaderScroll callback function.
