Document

To transfer a list of files to/from Java (and the underlying platform) a DataFlavor of this type/subtype and representation class of java.util.List is used.

Usage

From source file:MyTree.java

public boolean canImport(JComponent comp, DataFlavor[] transferFlavors) {
    if (comp instanceof MyTree) {
        for (int i = 0; i < transferFlavors.length; i++) {
            if (!transferFlavors[i].equals(DataFlavor.javaFileListFlavor)) {
                return false;
            }/* www . j  av  a  2s . com*/
        }
        return true;
    }
    return false;
