Of course we can make ListView the PageableListView.
Then we have 2 things:
Loop: this one just goes from 0-size() nothing fancy should be used as
an iterator.
ListView: is a pageable Loop that also gives some more control of the
ListItemModel (and maybe some more)
But then listview gets currentPage and numberOfRows (default both -1)
But as i said the Pageable component itself (the ListView) controls the
number of rows it displays
not the component that just gets that Pageable component to do something
with it. (what ever: jump to next, last or first)
So if ListView is pageable you get something like this:
ListView lv = new ListView();
lv.setRowsPerPage(30)
PageNavigator pn = new PageNavigator(lv);
attaching a PageNavigator to a listview that has the default rows per
page (-1) just doesn't make sense....
Also i don't like that PageXXX thing in all the names
We already have Pages in wicket. We shouldn't use that name i think
But who has a better idea??

Yes, the PageableListView will become a listview but behaves like the old
listview by default, once its attached to the navigator it (the navigator)
would set the rowsperpage property or whatever that ends up being called.
Maybe add setRowsPerPage to Ipageable? Not sure what the best way to do this
is, but it would sure be nice not to have the class tuples.

hmm don't know this yet
Then ListView just becomes PageableListView.
And you don't attach something to ListView.. it is the other
way around you attach PageableListview to a one of the
navigator components.

A little off topic, but I was under the impression that
with this new
framework there wont be a need for PageableListView as
ListView will
be able to handle the paging itself - or maybe merge them into one?
I know this was rejected before, but maybe something as simple as
attaching a paging navigator to a listview makes it
pageable and the
pagesize can be set up in the paging navigator.

Subject: [Wicket-develop] IPageable
I am busy with that now.
It is pretty much the same implementation we already have in the
wicket.markup.html.list package
So i moved it to
wicket.markup.html.navigation.paging
But if i make PageableListview implement IPageable then a lot does
change (we will break a lot that use PageableListview and its
navigator)
I also have the same question igor did a while ago (didn't
know if it
got answered) Why is a NavigationLink not just returning its own
page?
It is as far as i know always the same page as the list
view is on.
Or are there really situations that you are on Page X with
the next>>
link and you go then to Page Y where you display the Pageable
component?
If we need support for a different page then of course this can be
handled through the constructor but i want to know if this
is really
needed?
Now we have 4 kind of components:
1> PageNavigation., this one can display 1,2,3,4,5 those are:
2> PageNavigationLink, goes to one page (1,2,3 or first,last)
3> PageNavigationIncrementLink, -N or +N
and 4 is just a combination of those the PageNavigator. (just and
easy impl to get:
<< < 1 2 3 4 > >>
Of course if you have a DetailPage that has a Form that is
Pageable
then you only need the IncrementLink (next/prev record)
Besides these components we now also need a
PageRangeNavigationLink?
(that can display 1-10 , 11-20)
For this we need another interface
interface IRangePagable extends IPageable {
Range getRange()
}
class Range
{
public Range(int start, int end)
getStart() return start;
getEnd() return end;
}
Then if PageNavigation sees a IRangePagable then it will generate
PageRangeNavigationLink instead of PageNavigationLink
Comments?
