Greetings,
Just for clarification purposes....
Is it a 'feature' of the EditField's TextChange event to trigger
when the text changes as a result of going to a different record
in a database and populating the field with the new data?
Or, should the TextChange event be triggered only when someone
actively changes the text in the EditField, by typing or pasting
text into the EditField?
TextChange is called whenever the text changes.
Regardless of how the change is triggered.
A simple workaround is to use your own property (like
"TextHasChanged As Boolean" in the tutorial). This way you have
total control over opening new records or files and setting the
"SetWindowModified" widget on Mac. You can make this a window
property or a class property if you use a custom subclass of
Editfield.
The solution would be to set up another property that would be used
another property inside of an editable control object. Something like
RecordChange. TextChange being triggered when someone changes the
text in an EditField using typing or pasting. RecordChange being an
event that is triggered when a record from a database is changed.
Admittedly, RB would probably be more interested in your in-house
database system than Valentina. So it's unlikely RB would be made to
detect such a change in Valentina or any other database that wasn't
part and parcel of RB.
In the meantime, I've set up a boolean property to hold off updating
data in editable fields when there is a RecordChange going on. It's
'kludge', but not particularly egregiously so.
The only difficult part about it is making sure it is being properly
set whenever and wherever a record change is being triggered.
Otherwise, the database can get 'hosed'. This is especially true when
going from a VTable to a VCursor.
Regards,
Chuck
