Details

The horizontal scrolling unit assigned by _setHscroll determines the amount by which to scroll when users click either side of the thumb inside the scroll bar.

Because an extended table is not itself horizontally scrollable, you cannot place objects beyond the boundaries of the extended table's container box. The SCL program provides the scrolling functionality. When users scroll the table, the global variable _curcol is updated, based on the scroll amount, and contains the value of the leftmost column in the table. It is then up to the application to set values of objects correctly, based on the value of _curcol.
