A am wondering if there is a way to monitor when a uno object is being modified and optionally cancel changes.
There is the XModifyListener of course but it only know what happened not what is happening. So I guess I am looking for a XModifingListener or something of the sort.
For example if I wanted to attach a listener to a Calc Sheet or cell and watch for changing cell value and cancel the changes (perhaps display a message box) if certain criteria is not met (which can only be accessed in a macro). Would this be possible purely in code (python or basic)?
This would be similar behavior the the XVetoableChangeListener which can monitor the change of properties.
