EVENT_DRAG
Description
Tree and Tab Controls—When a user drags a tree item or tab page, LabWindows/CVI generates an EVENT_DRAG event and sends the event to the callback function associated with the control.
Splitter Controls—LabWindows/CVI generates and sends an EVENT_DRAG event at the beginning of the splitter operation.
This event is swallowable. Return 1 to swallow EVENT_DRAG.
