      • IMAGE

        public static final DataFormat IMAGE
        A special platform specific image type, such as is commonly used on the clipboard and interoperates widely with other applications. For example, on Mac this might ultimately be a TIFF while on Windows it might be a DIB (device independent bitmap).

      • FILES

        public static final DataFormat FILES
        Represents a List of Files.

    • Constructor Detail

      • DataFormat

        public DataFormat​(String... ids)
        Create a new DataFormat, specifying the set of ids that are associated with this data format. Typically the ids are one or more mime types. For each id, any data associated with this DataFormat will be registered on the clipboard. For example, suppose I had the following: 
        
     DataFormat fmt = new DataFormat("text/foo", "text/bar");
     Clipboard clipboard = Clipboard.getSystemClipboard();
     ClipboardContent content = new ClipboardContent();
     content.put(fmt, "Hello");
     clipboard.setContent(content);
        With the above code, if I were to look on the clipboard, I'd find the String "Hello" listed both for "text/foo" and "text/bar" on the clipboard.

        Note that the ids may be subject to platform restrictions in some cases. For instance, Swing requires a mime type so if an id is not of the "type/subtype" format it won't be possible to drag data of this type from/to JFXPanel.

        Parameters:
        ids - The set of ids used to represent this DataFormat on the clipboard.
        Throws:
        IllegalArgumentException - if one of the given mime types is already assigned to another DataFormat.
