Object Types: Panels, strip charts, text boxes, tables, tabs, and trees

Description: Panels and Strip Chart, Text Box, Table, and Tree Controls—When the user scrolls a panel or strip chart, text box, table, or tree control horizontally, LabWindows/CVI generates an EVENT_HSCROLL event and sends the event to the panel or control callback function.
Tab Controls—When the user scrolls through the tab control, LabWindows/CVI generates an EVENT_HSCROLL event and sends the event to the control callback function.

This event is not swallowable.
