[nebula-dev] Re: [compositeTable] refresh single row

["David J. Orme" <djo@xxxxxxxxxxxxxxxxxxxxxxxxx>]

Heres what I do:

0) Before I bind a row, I getData and look for a data binding context
that had been previously used to bind the row.  If I find one, I
dispose the DBC.
1) Use data binding to bind the controls in each row to the data model directly in CompositeTable's refresh event.
2) Store the data binding context I used to bind the row in the row object itself using setData.

Then data binding will automatically do individual row refreshes whenever the underlying model changes. :-)

Given the above, do you still feel like the manual refreshRow() API is necessary?  If so, I'm willing to add it; just submit a patch. :-)


Regards,

Dave

Hi Dave

I suppose you're right in the middle of your client change and when I see
the weather reports on north america, I guess you have plenty of thing to
do / snow to shovel :-(

I am building a cell-editor 'framework' and I have the need to refresh a
single row (the currently edited one). My need is due to sort of
autocomplete-functionality (ex. you fill in the committers age and the
(model-) 'autocompleter component' fills in the age automatically. In my
usecase the age is  still a suggestion and must still be editable by the
user (which is of course not for my simple example :-)
I implemented all my stuff in a custom EditableRow that triggers a
ICellModifyEvent. The user programmer (that completely handles all model
changes) may then insert the age-value in the model and request the table
to refresh the row that currently shows the model-entry.
For that aim I need a method where the user-programmer may request the
table to refresh a single row. Do you agree with my idea/handling of this
functionality? I you do so I'll - as usual :-) - submit the stuff to
bugzilla.

CompositeTable:
  public void refreshRow(int row) {
    if (contentPane != null) {
      contentPane.refreshRow(row);
    }
  }

InternalCompositeTable:
  public void refreshRow(int row) {
    if (!isRowVisible(row)) {
      return;
    }
    fireRefreshEvent(topRow + currentRow,
getRowByNumber(row).getRowControl());
        }


I may commit-back the whole cellEditor stuff when it's ready, if you think
it would be of any use for the table users.

Regards
Andr�
