<description><p>A class for manipulating the clipboard.
      </p><p>To use the clipboard, you call member functions of the global ?wxTheClipboard object.
      </p><p>See the overview_dataobject for further information.
      </p><p>Call <seemfa marker="#open/1"><c>open/1</c></seemfa> to get ownership of the clipboard. If this operation returns true, you now own the clipboard. Call <seemfa marker="#setData/2"><c>setData/2</c></seemfa> to put data on the clipboard, or <seemfa marker="#getData/2"><c>getData/2</c></seemfa> to retrieve data from the clipboard. Call <seemfa marker="#close/1"><c>close/1</c></seemfa> to close the clipboard and relinquish ownership. You should keep the clipboard open only momentarily.
      </p><p>For example:
      </p><p>Note: On GTK, the clipboard behavior can vary depending on the configuration of the end-user's machine. In order for the clipboard data to persist after the window closes, a clipboard manager must be installed. Some clipboard managers will automatically flush the clipboard after each new piece of data is added, while others will not. The @Flush() function will force the clipboard manager to flush the data.

      </p><p>On the other platforms, there is no PRIMARY selection and so all clipboard operations will fail. This allows implementing the standard X11 handling of the clipboard which consists in copying data to the CLIPBOARD selection only when the user explicitly requests it (i.e. by selecting the "Copy" menu command) but putting the currently selected text into the PRIMARY selection automatically, without overwriting the normal clipboard contents with the currently selected text on the other platforms.
