When using a browser in my progress application the scroll bars never work correctly

When using a browser in my progress application the scroll bars never work correctly. It will show that I can only scroll down a little but then keeping going. Is this a bug in progress or is there something I can do to fix this problem?

DEFINE BROWSE BROWSE-4
QUERY BROWSE-4 NO-LOCK DISPLAY
  custNum name
/* ENABLE name */
WITH NO-ROW-MARKERS SEPARATORS SIZE 32 BY 6.46 FIT-LAST-COLUMN.
.

open query browse-4 preselect each customer no-lock.

enable browse-4.

wait-for window-close of current-window.

This is a known "feature" of Openedge GUI, unfortunately.

The position of the slider on the right of the browse is not directly related to the number of records in the query, but to the "Max Data Guess" property of the browse.

You can set this value yourself in the property dialogue for the browse widget (it's just below the "query" editor, in v10 at least).

Just set it to a really big number (say 10,000) and the browse will behave as it should.

You may be confusing the scrollbar on the containing frame with the scrolling of the browse.

Do you see two boxes outlining the browse? If you add "with no-box" to your "enable" does the scrollbar that is bothering you go away?

If it does then the problem is that your containing frame (which is the default un-named frame because you have not specified a frame phrase with the ENABLE) is smaller than the browse viewport. So you are seeing a scrollbar on the FRAME, not on the BROWSE, that is trying to tell you that you can scroll the frame up and down to see the complete viewport of the browse. The browse may also scroll within that containing frame depending on how much data there is.

If you are running this code in a character (Unix) environment you should also be aware that many GUI features of the BROWSE are not available. Especially anything related to appearance. Like scrollbars.

You can adjust the MAX-DATA-GUESS property for the browse. You can get the value from NUM-RESULTS after the preselect query has been opened. Or you can set it to a suitable guesstimate without using preselect.

Keep in mind that using preselect causes every record to be read instead of just enough to fill the first browse window. That is potentially a lot of extra DB reads and network traffic just to get the scrollbars correct.
