GridLayout Events

Events in the View Designer

  • onDrop

    Assignment of the action to be executed when the user moves an entry or multiple entries in the GridLayout by means ofDrag&Drop.

    You can only use this event in dynamic programming. Therefore, create a DragSourceInfo and a DropTargetInfo, append these to the GridData, and set the event dynamically.

    Note that Drag&Drop is only possible with a one-column GridLayout.
