|
# Each TTkWidget include 4 methods to handle the Drag and Drop events: |
|
# - dragEnterEvent |
|
# - dragLeaveEvent |
|
# - dragMoveEvent |
|
# - dropEvent |
|
# Overriding any of those methods in a subclass will allow the widget to handle the DnD events |
|
# |
|
# To start a Drag and Drop operation, the TTkDrag object must be created and executed. |
|
# The Drag and Drop operation is usually started after a mouseDragEvent as shown in |
|
# this example, but it can be started after any other events/methods or signals. |
