Martin Grigorov commented on WICKET-5520:
-----------------------------------------
It will be much easier if you just attach a patch! :-)
> improve reusability of DataTable and AbstractPageableView
> ---------------------------------------------------------
>
> Key: WICKET-5520
> URL: https://issues.apache.org/jira/browse/WICKET-5520
> Project: Wicket
> Issue Type: Improvement
> Components: wicket, wicket-extensions
> Affects Versions: 6.14.0
> Reporter: Dirk Germonpré
>
> I have a use case for the
> org.apache.wicket.extensions.markup.html.repeater.tree.TableTree that asks
> for some small modifications to the classes
> org.apache.wicket.extensions.markup.html.repeater.data.table.DataTable and
> org.apache.wicket.markup.repeater.AbstractPageableView. I would like to show
> a tree structure (only one level deep) in the TableTree where the number of
> items on a single page is not a fixed number of lines, but the number of top
> level nodes of the tree structure.
> For this the following changes are needed:
> In AbstractPageableView the method getPageCount should no longer be final.
> In DataTable the constructor creates a DataGridView and assigns is to the
> member datagrid. The creation of the DataGridView should be refactored to a
> factory method (for example newDataGrid). The anonymous inner class should be
> replaced by a named inner class (a good name would be DefaultDataGridView).
> This inner class should be protected, so it can be subclassed.
