Adding a Search Filter to the Columns Table in Organize Table Form

[nisrael]

It’s great to have a place again to discuss Eclipse Scout! Here’s a question I originally wanted to post on StackOverflow but realized it wasn’t the right place. In the meantime, by revisiting the Scout RT code, I found a solution.

Problem:

In our application, we use TablePages with many columns. Finding the right column in the "Organize Table" form is difficult because the Columns table does not have a search function. However, the Saved Settings table in the same form does have a search function.

I wanted to know if it was possible to add a similar search function to the Columns table.

Solution:

It turns out that adding this functionality is relatively simple! The text filter functionality is already part of the table but disabled in the Columns table.

There is also an @ApplicationScoped factory called OrganizeColumnsFormProvider, which creates the "Organize Columns" form. By replacing this provider, we can enable text filtering in the Columns table.

Here's how to do it:

@Replace
public class OrganizeColumnsWithTextFilterFormProvider extends OrganizeColumnsFormProvider {

  @Override
  public IOrganizeColumnsForm createOrganizeColumnsForm(ITable table) {
    var form = super.createOrganizeColumnsForm(table);
    form.getFieldByClass(ColumnsTableField.class).getTable().setTextFilterEnabled(true);
    return form;
  }
}
