 No, not quite: if you had data in any other format on the clipboard they
wouldn't be cleared by Add(). But you can have only one piece of data in
wxDF_TEXT format on clipboard at any time (but also, simultaneously, one in
wxDF_BITMAP format and so on).

 So you just need to collect all the text data you want to put on clipboard
in one wxString and then call AddData() once.
