Drag and Drop with multicolumn Listbox

[Jokelnice]

Overview
The example demonstrates using the “Drag Starting?”, “Drag Enter” And “Drop” events to customize the default drag/drop behavior.

Description

LabVIEW’s default drag/drop behavior only requires that dragging and dropping be enabled at the source and destination controls, and that the datatype of the source and destination be simple and match. This VI applies a custom name (Info) to the dragged data in the My Listbox “Drag Starting?” event and then uses that name to decide whether or not the Data indicator will accept the drop in its “Drag Enter” and “Drop” events. This technique is important to remember when you have multiple drag sources and destinations with similar datatypes. For more information see the “Implementing Custom Drag-and-Drop Behavior” topic in LabVIEW Help.

Requirements

• LabVIEW 2012 (or compatible)

Steps to Implement or Execute Code

1. Run the program.
