Useful browser properties

The code runs the standard initializeObject behavior and then captures three property values locally:

The DisplayedFields property holds a comma-separated list of all the column names in the browse. Since you are only interested (for the purposes of this example at least) in looking at values in the browse itself, this is all you need. Note that the AllFieldNames and AllFieldHandles properties are defined for the browser, as they are for viewers, but they hold only the name and handle of the browse widget itself, along with any additional fields or other widgets that you might add to the browser’s frame, not the names and handles of the browse columns themselves. So they are not useful for your purposes here.
The FieldHandles property holds a comma-separated list of the widget handles of the browse cells, in the same order as the DisplayedFields list.
The QueryRowObject property holds the handle of the record buffer for the RowObject table in the SDO that is used to populate the browse. This is needed because, within the ROW-DISPLAY event trigger where the custom code executes, it is not possible to inspect the SCREEN-VALUEs of the cells themselves, so the widgetValue function looks at the corresponding RowObject fields instead, as shown:

PROCEDURE initializeObject /*--------------------------------------------------------------------- Purpose: ScrollRemote enables the rowDisplay trigger on the browse's ROW-DISPLAY event, used to customize cell color etc. Parameters: <none> Notes: ---------------------------------------------------------------------*/ DYNAMIC-FUNCTION("setScrollRemote" IN TARGET-PROCEDURE, TRUE). RUN SUPER. {get DisplayedFields gcFields}. {get FieldHandles gcHandles}. {get QueryRowObject ghBuffer}. END PROCEDURE.

The variables gcFields, gcHandles, and ghBuffer must be defined in the Definitions section of the procedure, so that they are scoped to the procedure as a whole, as shown:

DEFINE VARIABLE gcFields AS CHARACTER NO-UNDO. DEFINE VARIABLE gcHandles AS CHARACTER NO-UNDO. DEFINE VARIABLE ghBuffer AS HANDLE NO-UNDO.
