EVENT_HSCROLL
Description
Panels and Strip Chart, Text Box, Table, and Tree Controls—When a 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 callback function associated with the panel or control.
Tab Controls—When a user scrolls through the tab control, LabWindows/CVI generates an EVENT_HSCROLL event and sends the event to the callback function associated with the tab control.
This event is swallowable for tab controls. Return 1 to swallow EVENT_HSCROLL.
