Why doesn't a vertical scroll bar work on a browse?
A LISTBOX displays the entries from a QUEUE that has been
specified for the LISTBOX. If there are 10 rows in the LISTBOX
and 100 enties in the QUEUE associated with this LISTBOX
then the vertical scroll bar will scroll the entries
within the LISTBOX. If however there are only 10 records in
the QUEUE then the vertical scroll bar does nothing.
The BROWSE procedure generates code that creates a QUEUE and reads
the same number of entries into that QUEUE as rows in the LISTBOX.
Therefore a vertical scroll bar on a BROWSE LISTBOX will not scroll
records and should not be used.
To move up and down in a BROWSE LISTBOX you can do the following:
PageUp / PageDown
ArrowUp / ArrowDown
Press the right mouse button in the top portion of the LISTBOX to
up and in the bottom portion to move down.
The LIST template generates code that reads all the records
requested into a QUEUE. In this case the vertical scroll bar
in practical.
