====== Essais ======

Dans la méthode canImport() du javax.swing.TransferHandler voici les DataFlavor obtenus (support.getDataFlavors()):
<code java>
for (java.awt.datatransfer.DataFlavor df : support.getDataFlavors()) {
 System.out.println(df.getHumanPresentableName() + " - " + df.getMimeType()+" - "+df.getSubType() + " - " + df.getDefaultRepresentationClassAsString());
}
</code>

===== Linux XUbuntu =====

Avec Linux XUbuntu: Drag d'un fichier depuis le gestionnaire de fichier Thunar vers un JTextField. Quelque soit le type de fichier ("Text", "Png") l'appel à support.getDataFlavors() donne :
<code>

Et l'appel à DataFlavor.selectBestTextFlavor()
<code java>
java.awt.datatransfer.DataFlavor df = java.awt.datatransfer.DataFlavor.selectBestTextFlavor(support.getDataFlavors()) ;
System.out.println(df.getHumanPresentableName() + " - " + df.getMimeType()+" - "+df.getSubType() + " - " + df.getDefaultRepresentationClassAsString());
</code>
donne:
<code>
text/uri-list - text/uri-list; class=java.io.Reader; charset=Unicode - uri-list - java.io.InputStream
</code>

===== Windows XP =====

Avec Windows l'appel à support.getDataFlavors() donne:
<code>
application/x-java-file-list - application/x-java-file-list; class=java.util.List - x-java-file-list - java.io.InputStream
</code>

Et l'appel ) DataFlavor.selectBestTextFlavor() donne:
