Clipboard Viewer Windows

A window adds itself to the clipboard viewer chain by calling the SetClipboardViewer function. The return value is the handle of the next window in the chain. To retrieve the handle of the first window in the chain, call the GetClipboardViewer function.

Each clipboard viewer window must keep track of the next window in the clipboard viewer chain. When the content of the clipboard changes, the system sends a WM_DRAWCLIPBOARD message to the first window in the chain. After updating its display, each clipboard viewer window must pass this message on to the next window in the chain.

Before closing, a clipboard viewer window must remove itself from the clipboard viewer chain by calling the ChangeClipboardChain function. The system then sends a WM_CHANGECBCHAIN message to the first window in the chain.

For more information about processing the WM_DRAWCLIPBOARD and WM_CHANGECBCHAIN messages, see Creating a Clipboard Viewer Window.
