|59||Input of the ||The user scrolls the contents of a picture object or list box using the mouse or keyboard.|
This event can be generated in the context of a picture input or a list box.
The event is triggered when the scroll is the result of a user action: using the scroll bars and/or cursors, using the mouse wheel or the keyboard. It is not generated when the object is scrolled due to the execution of the
OBJECT SET SCROLL POSITION command.
The event is generated as soon as a user scrolls a picture within the picture input (field or variable) that contains it. You can scroll the contents of a picture area when the size of the area is smaller than its contents and the display format is "Truncated (non Centered)".
The event is generated as soon as a user scrolls the rows or columns of the list box.
