TWebClipboard is a non-visual control that manages paste from the clipboard at window level in the browser. When the user performs paste either from the browser menu or via the keyboard shortcut Ctrl-V, the TWebClipboard.OnTextData or TWebClipboard.OnImageData is triggered. When the user pasted text, OnTextData is triggered returning the text. When the user pasted an image, the event OnImageData is triggered returning the image as base64 encoded data URL.

The TWebClipboard component also allows to programmatically put text on the clipboard. This can be done via:

TWebClipboard.CopyToClipboard(const AValue: string);
