Value will be set to 1 if the cell indicated by XTR'XROW and XTR'XCOL needs validation. Previously you had to rely on exitcode -48 to identify when validation was needed, but this is not adequate when the event which terminates an editable cell operation is a click on another control that generates its own exitcode. In that case, the exitcode returned to the application will be that of the clicked-on control, and the XTR'XVALIDATE flag will be handy to indicate that the cell identified by XTR'XROW and XTR'XCOL needs to be validated.

In some cases, the cell which needs to be validated is not the one that last had the focus, i.e. the one referenced by XTR'XROW / XTR'XCOL, but the one which gets the focus, i.e. XTR'TARGETROW / XTR'TARGETCOL. This is often the case with checkboxes, which exit for validation only when checked, and is always the case with read-only editable cells, which exit for validation just before they get the focus. In these cases, XTR'XVALIDATE will be set to 2.

This could have two possible means, depending on the context. One possibility occurs when clicking out of a cell that requires post-validation and into a cell that requires pre-validation or validation-on-click, in which case it means that both the XTR'XROW / XTR'XCOL and XTR'TARGETROW / XTR'TARGETCOL cells need validation. The other possibility is that the user selected the $CBSET, $CBRST, or $CBUNDO command from a PopupMenu to set, reset, or undo the state of all the checkboxes in the current column.

4

Indicates that the user clicked on a $CBSETDEP or $CBRSTDEP PopupMenu command to set or reset the dependent checkboxes for the current item.

5

In an editable tree without validation, a value of 5 indicates that at least one cell was changed during the session.
