Class CalendarMonthDropHandler

Constructor Detail

• CalendarMonthDropHandler

  public CalendarMonthDropHandler​(CalendarConnector connector)

Method Detail

• dragAccepted

  protected void dragAccepted​(VDragEvent drag)

  Description copied from class: VAbstractDropHandler

  This method is called when a valid drop location was found with AcceptCriterion either via client or server side check.

  Implementations can set some hints for users here to highlight that the drag is on a valid drop location.

  Specified by:

  dragAccepted in class VAbstractDropHandler

• dragOver

  public void dragOver​(VDragEvent drag)

  Description copied from class: VAbstractDropHandler

  Default implementation does nothing.

  Specified by:

  dragOver in interface VDropHandler

  Overrides:

  dragOver in class VAbstractDropHandler

• dragEnter

  public void dragEnter​(VDragEvent drag)

  Description copied from class: VAbstractDropHandler

  The default implementation in VAbstractDropHandler checks if the Transferable is accepted.

  If transferable is accepted (either via server visit or client side rules) the default implementation calls abstract VAbstractDropHandler.dragAccepted(VDragEvent) method.

  If drop handler has distinct places where some parts may accept the Transferable and others don't, one should use similar validation logic in dragOver method and replace this method with empty implementation.

  Specified by:

  dragEnter in interface VDropHandler

  Overrides:

  dragEnter in class VAbstractDropHandler

  Parameters:

  drag - DragEvent which contains the transferable and other information for the operation
