Stores concomitant information for drag-and-drop-related events in gallery controls.
#Declaration
TdxGalleryControlDragObject = class(
TcxDragControlObject
)
#Remarks
This class extends its ancestor with members that allow you to do the following:
Access the control that raised the OnDragOver or OnDragDrop event (Control).
Track dragged gallery items (SelectedItems).
A gallery control’s OnDragOver and OnDragDrop events pass a TdxGalleryControlDragObject object into their handlers as the Source parameter. Cast the parameter value to the TdxGalleryControlDragObject class to access its members.
