NAME

       wxTextDataObject - Functions for wxTextDataObject class

DESCRIPTION

       wxTextDataObject  is  a  specialization  of wxDataObjectSimple (not implemented in wx) for
       text data. It can be used  without  change  to  paste  data  into  the  wxClipboard  or  a
       wxDropSource  (not  implemented  in  wx).  A user may wish to derive a new class from this
       class for providing text on-demand in order to minimize memory consumption  when  offering
       data  in several formats, such as plain text and RTF because by default the text is stored
       in a string in this class, but it might as well be generated  when  requested.  For  this,
       getTextLength/1 and getText/1 will have to be overridden.

       Note  that  if  you  already  have  the  text  inside  a  string, you will not achieve any
       efficiency gain by overriding these functions because copying wxStrings is already a  very
       efficient operation (data is not actually copied because wxStrings are reference counted).

       See:   Overview   dnd,   wxDataObject,   wxDataObjectSimple   (not   implemented  in  wx),
       wxFileDataObject, wxBitmapDataObject

       This class is derived (and can use functions) from: wxDataObject

DATA TYPES

       wxTextDataObject() = wx:wx_object()

EXPORTS

       new() -> wxTextDataObject()

       new(Options :: [Option]) -> wxTextDataObject()

              Types:

                 Option = {text, unicode:chardata()}

              Constructor, may be used to initialise the text (otherwise setText/2 should be used
              later).

       getTextLength(This) -> integer()

              Types:

                 This = wxTextDataObject()

              Returns the data size.

              By  default,  returns  the  size  of  the text data set in the constructor or using
              setText/2. This can be overridden to  provide  text  size  data  on-demand.  It  is
              recommended  to  return the text length plus 1 for a trailing zero, but this is not
              strictly required.

       getText(This) -> unicode:charlist()

              Types:

                 This = wxTextDataObject()

              Returns the text associated with the data object.

              You may wish to override this method when offering data on-demand, but this is  not
              required by wxWidgets' internals. Use this method to get data in text form from the
              wxClipboard.

       setText(This, StrText) -> ok

              Types:

                 This = wxTextDataObject()
                 StrText = unicode:chardata()

              Sets the text associated with the data object.

              This method is called when the data object  receives  the  data  and,  by  default,
              copies  the  text  into the member variable. If you want to process the text on the
              fly you may wish to override this function.

       destroy(This :: wxTextDataObject()) -> ok

              Destroys the object.
