scrollbarBeginning

Type

message

Summary

Sent to a scrollbar when the user Shift-clicks its decrease arrow.

Syntax

scrollbarBeginning <pStart>

Description

Handle the scrollbarBeginning message if you want to respond to the use of Shift-click to move the scrollbar thumb directly to the beginning (the top or left) of the scrollbar.

Dragging the scrollbar thumb to the beginning position, or otherwise moving it to the beginning, does not send a scrollbarBeginning message.

If the scrollbarBeginning message is not handled, a scrollbarDrag message is sent in addition.
