B4J Code Snippet Put files in clipboard from non-ui programs

The standard way to set the clipboard content is with jFX.Clipboard, however this is only available in UI apps.
An alternative solution based on AWT, which is always available:

Private Sub PutFilesInClipboard (Files As List)
    Dim FilesList As List
    FilesList.Initialize
    For Each f As String In Files
        Dim jo As JavaObject
        jo.InitializeNewInstance("java.io.File", Array(f))
        FilesList.Add(jo)
    Next
    Me.As(JavaObject).RunMethod("putFiles", Array(FilesList))
End Sub

#If Java
import java.awt.datatransfer.Transferable;
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.DataFlavor;
import java.awt.datatransfer.UnsupportedFlavorException;
import java.awt.Toolkit;
public static void putFiles(java.util.List files) {
    Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
    Transferable transferable = new Transferable() {
        private final DataFlavor[] flavors = { DataFlavor.javaFileListFlavor };

        @Override public DataFlavor[] getTransferDataFlavors() { return flavors; }

        @Override public boolean isDataFlavorSupported(DataFlavor flavor) {
            return DataFlavor.javaFileListFlavor.equals(flavor);
        }

        @Override public Object getTransferData(DataFlavor flavor) throws UnsupportedFlavorException {
            if (!isDataFlavorSupported(flavor)) throw new UnsupportedFlavorException(flavor);
            return files;
        }
    };
    clipboard.setContents(transferable, null);
}
#End If

Note that it is not exactly clear in the documentation whether the content will be available after the program ends. Based on my tests on Windows, the content remains valid after the program ends.
