Drag and Drop

For some types of controls, WINDEV and WEBDEV propose an automatic management of Drag and Drop: to do so, check the corresponding option in the "Details" tab of the control description. Then, a control can be defined as source or target of Drag and Drop.
The automatic Drag and Drop is available:
  • WINDEV for the edit controls, the list boxes, the listviews, the treeviews.
During a Programmed Drag and Drop, ..DndSource and ..DndTarget are used to define the source and target controls of Drag and Drop.
..DndTarget is used to find out and modify the behavior of a control during Drag and Drop. This control will be defined as target for "Drag and Drop", which means that "Drag and Drop" will be performed toward this control.
Example
WINDEV
// -- Initialize the LIST_Source list
// LIST_Source is not a target
LIST_Source..DndTarget = dndInactive

// -- Initialize the LIST_Target list
LIST_Target..DndTarget = dndProgram
DnDEvent("Drop", "LIST_Target", dndDrop)
DnDEvent("DragOver", "LIST_Target", dndDragOver)
