datagrid/dataedit without datastore?
Willem Rein Oudshoorn
The standard datagrid/dataedit widget has most of the functionality I
want. However I am struggling with the datasource side of things.
I would like to give the datagrid an explicit list of items, and the
datastore seems to be getting in my way.
So take the following example, I have a class 'person and
want to display a list of persons in datagrid.
I would like to show two (or more) lists of persons, lets say:
1 - Friends
2 - Enemies
Now as far as I can tell I can configure the datagrid
with
:data-class 'person
However this will show all persons in a datagrid.
Does anybody have an idea or pointers how to approach this?
I can think of one way to do this, but that seems cumbersome:
- For each instance of the datagrid make a specific datastore
- Carefully manage each datastore to have the right instances.
So is there a better/easier way?
Oh note, I am not (at the moment :-)) interested
in persistence.
Kind regards

Take a look at the on-query slot; just specialize a datagrid
to use your own function there (which in turn can derive
the objects to return from the data-class slot, or have
its own logic to decide between Friends and Enemies).

Thank you for the hint. It took a few tries but I got it working.
Kind regards,
