add-type

Adds a new data format name to the list supported by this clipboard client.

• (send a-wx:clipboard-client add-type format) -> void
      format : string

  The format string is typically four capital letters. (On the Macinotsh, only four characters for format are ever used.) For example, "TEXT" is the name of the simple text format. New format names can be used to communicate application-specific kinds of data through the clipboard.
