The SetClipboardViewer function adds the specified window to the chain of clipboard viewers. Clipboard viewer windows receive a WM_DRAWCLIPBOARD message whenever the content of the clipboard changes.
Syntax
HWND SetClipboardViewer(
HWND hWndNewViewer
);
Parameters
- hWndNewViewer
-
[in] Handle to the window to be added to the clipboard chain.
Return Value
If the function succeeds, the return value identifies the next window in the clipboard viewer chain. If an error occurs or there are no other windows in the clipboard viewer chain, the return value is NULL. To get extended error information, call GetLastError.
Remarks
The windows that are part of the clipboard viewer chain, called clipboard viewer windows, must process the clipboard messages WM_CHANGECBCHAIN and WM_DRAWCLIPBOARD. Each clipboard viewer window calls the SendMessage function to pass these messages to the next window in the clipboard viewer chain.
A clipboard viewer window must eventually remove itself from the clipboard viewer chain by calling the ChangeClipboardChain function — for example, in response to the WM_DESTROY message.
For an example, see Adding a Window to the Clipboard Viewer Chain.
