void* Flu_DND_Event::data (   )  const [inline]

the dragged object data as added in Flu_DND::dnd_grab() if this event is an "other" event (see event_is_other() ) Note: This is valid only after the object has been dropped (i.e. in Flu_DND::on_dnd_drop() )

const char* Flu_DND_Event::data_type (   )  const [inline]

the type of the data object that was dropped. This is NULL for FLTK text events Note: This is valid only after the object has been dropped (i.e. in Flu_DND::on_dnd_drop() )

const char* Flu_DND_Event::text (   )  const [inline]

the text from Fl::copy() if this event is a text event (see event_is_text() ) Note: This is valid only after the object has been dropped (i.e. in Flu_DND::on_dnd_drop() )
