- Forwards the handling of this control's drag and drop to [param target] object.
- Forwarding can be implemented in the target object similar to the methods [method _get_drag_data], [method _can_drop_data], and [method _drop_data] but with two differences:
- 1. The function name must be suffixed with [b]_fw[/b]
- 2. The function must take an extra argument that is the control doing the forwarding

+ Forwards the handling of this control's [method _get_drag_data], [method _can_drop_data] and [method _drop_data] virtual functions to delegate callables.
+ For each argument, if not empty, the delegate callable is used, otherwise the local (virtual) function is used.
+ The function format for each callable should be exactly the same as the virtual functions described above.
