MWAPI - SCROLL

1995 Version of ANSI (Equivalent to Current ISO Version) of Standard

SCROLL specifies scrolling behavior for a gadget’s data.

If the value of the hsize component of SCROLL is greater than 0 (zero), horizontal scrolling can occur and the horizontal size of the data is specified by hsize. If the value of the hsize component of SCROLL is equal to 0 (zero), horizontal scrolling can occur but no explicit horizontal size is specified for the data. If hsize is omitted, horizontal scrolling cannot occur.

If the value of the vsize component of SCROLL is greater than 0 (zero), vertical scrolling can occur and the vertical size of the data is specified by vsize. If the value of the vsize component of SCROLL is equal to 0 (zero), vertical scrolling can occur but no explicit vertical size is specified for the data. If vsize is omitted, vertical scrolling cannot occur.

The unit of measure is determined in the same manner as is specified for the SIZE elattribute.

A scroll bar may or may not be present when it is not required.

If an application attempts to assign a SCROLL value that contains a negative value for hsize or vsize, an error occurs with $ECODE containing ",M?2," and $EREF containing a value that indicates the ssvn reference for which the error occurred.
