On Unix, a second clipboard<%> object, the-x-selection-clipboard , manages the content of the system-wide X11 selection. If the 'GRacket:selectionAsClipboard preference preference (see Preferences) is set to a non-zero true value, however, then the-clipboard is always the same as the-x-selection-clipboard , and the system-wide X11 clipboard is not used.
On Windows and Mac OS, the-x-selection-clipboard is always the same as the-clipboard .
Data can be entered into a clipboard in one of two ways: by setting the current clipboard string or byte string, or by installing a clipboard-client% object. When a client is installed, requests for clipboard data are directed to the client.
Generic data is always retrieved from the clipboard as a byte string. When retrieving clipboard data, a data type string specifies the format of the data string. The availability of different clipboard formats is determined by the current clipboard owner.

See get-clipboard-data for information on eventspaces and the current clipboard client.
See Cut and Paste Time Stamps for a discussion of the time argument. If time is outside the platform-specific range of times, an exn:fail:contract exception is raised.

If the clipboard client is associated to an eventspace that is not the current one, the data is retrieved through a callback event in the client’s eventspace. If no result is available within one second, the request is abandoned and #f is returned.
See add-type in clipboard-client% for information on format.
See Cut and Paste Time Stamps for a discussion of the time argument. If time is outside the platform-specific range of times, an exn:fail:contract exception is raised.
