drag & drop issue on Mac

[Yahya Elyasse]

Hi all;

i wrote a transferhandler to drag files from the OS desktop to a JTable in my java application. the code works fine on windows platform but can't have it working for Mac OS

below is the source code of my transfer handler...it seems the problem for Mac OS resides in the line :

 if (data instanceof List)   

this condition seems to fail always for mac as i never get the debug text when i run on mac but the code runs well on win xp.
can someone point me what's the problem.
thanks.

the code :

public boolean canImport(JComponent comp, DataFlavor[] flavors) {
for (int j = 0; j < flavors.length; j++) {
if (FileBrowserTransferHandler.fileFlavor.equals(flavors[j])
|| DataFlavor.javaFileListFlavor.equals(flavors[j])) {
return true;
}
}
return false;
}

public boolean importData(JComponent comp, Transferable t) {
if (canImport(comp, t.getTransferDataFlavors())) {
File[] xferData = null;
  DataFlavor[] f=t.getTransferDataFlavors();
  for(int i=0;i<f.length;i++){
try {
Object data = t.getTransferData(f[i]);
if (data instanceof List) {
List fileList = (List) t
.getTransferData(DataFlavor.javaFileListFlavor);
System.out.println("debug file drop ->files list :"+fileList);
up.addFiles((File[]) fileList.toArray(new File[fileList
.size()]));
return true;
}
if (data instanceof File[])
xferData = (File[]) t
.getTransferData(FileBrowserTransferHandler.fileFlavor);
} catch (UnsupportedFlavorException ufe) {
ufe.printStackTrace();
return false;
} catch (IOException ioe) {
ioe.printStackTrace();
return false;
}
 
up.addFiles(xferData);
return true;
}
}
return false;
}
