Java Drag & Drop
Essais
Avec Linux XUbuntu: Drag d'un fichier depuis le gestionnaire de fichier Thunar vers un JTextField.
Dans la méthode canImport() du javax.swing.TransferHandler voici les DataFlavor obtenus (support.getDataFlavors()):
for (java.awt.datatransfer.DataFlavor df : support.getDataFlavors()) { System.out.println("canImport() DataFlavor: " + df.getHumanPresentableName() + ", " + df.getMimeType() + ", " + df.getDefaultRepresentationClassAsString()); }
Quelque soit le type de fichier (“Text”, “Png”) le print ci-dessus donne :
