Mac: DragAndDrop: Dragging files to the finder does not work

    Details

    • Type: Bug
    • Status: Resolved
    • Priority: P4
    • Resolution: Fixed
    • Affects Version/s: 7u15, 8
    • Fix Version/s: 8
    • Component/s: javafx
    • Environment:

      Mac OS X 10.8.3, JavaFX 2.2.7-b01, JavaFX 8.0.0-ea-b82

      Description

      We want to drag a java.io.File from our JavaFX application to the Mac OS X finder or desktop. But no matter what we try the dragged File is not accepted (little stop sign on the dragged image).

      It works on Ubuntu and Windows XP.

      We put the Files into the ClipboardContent using clipboardContent.putFiles(). There is an example attached as well.

      If we output the ContentTypes of the Dragboard we get an additionally [placeholder.custom.bytes] entry:

      System.out.println(t.getDragboard().getContentTypes()):
      [[placeholder.custom.bytes], [application/x-java-file-list, java.file-list]]

      We wonder if this might be the cause that Mac OS X gets confused or something.

      SSCCE attached:
