Hello Team IBO

I want to suggest that the criteria by which a TIB_ComboBox tells its parent transaction to set TransactionState to tsActive should be changed. Being new to Interbase and IBObjects I welcome correction to any misunderstanding I have.

The background to my comments is I have D5 forms using several iboControls, all using a TIB_Query and one TIB_Transaction. The work unit my app user does is accepted or rejected by them by pressing, naturally, an accept or reject button. So I need to manage programatically when the accept/reject buttons are enabled.

Users may change several rows in one work unit, to allow for this I have a TIB_NavigationBar on the form. The state property of the TIB_Query cannot be used to enable/disable the accept/reject buttons because its state property is reset to dssBrowse when the current row changes. So uncommited changes are not detected by examining the TIB_Query state.

I am using Accept/RejectButtons.enabled := Transaction.TransactionIsActive.

This works correctly as far as I can tell, except for the TIB_ComboBox. If a user pulls down the ComboBox list and selects the existing choice the transaction state switches to tsActive, and I interpret this as the user has made a change. From my users viewpoint they have not made a change, but I am enabling the accept/reject buttons because I rely on the transaction state for this.

The change I suggest is the TIB_ComboBox behave like the TIB_LookupCombo and not cause the transaction to go active when the existing selection is reselected. (I can probably achieve what I want by adding code inside my app but it may be better to change the TIB_ComboBox)

This change makes sense to me in that it makes the TIB_ComboBox behaviour consistent with other controls and it solves my problem. Perhaps there are reasons not to make the change?

Is there a better way to manage Accept/RejectButton.Enabled?

(The IBO version I am using is 3.6Dg or h or i. The version code on the components says g. With D5. )

Thanks

Russell
