Re: DataView the easy way?
I almost have it... I have my ArrayList of lists, so I guess my code should
look smth like that:
ArrayList<ArrayList<Long>> colonisations =
MySession.loggedInUser.colonisations;
add(new DataView("expeditionsView", new
ListDataProvider(colonisations))
{
@Override
protected void populateItem(final Item item)
{
ArrayList expedition = (ArrayList)item.getModelObject();
// "item" represents the current "row-component"
item.add(new Label("title", expedition.get(0)));
item.add(new Label("price", expedition.get(1)));
}
});
I must be doing some fundamental mistake here, as it can't work. It throws
"cannot find symbol: symbol constructor Label" at both item.add lines

Re: DataView the easy way?
Hi Zeldor,
the populateItem-method is used to populate the rows of your table.
Basically, you can add the "cells" of your rows there. DataView will
loop through the elements of your collection automatically, and for
every element in the collection call the populateItem-method with the
current element passed as a parameter.
So by slightly modifying the SimplePage that Martin suggested to match
your case you should get something like this:
List colonisations = ...; // initialized somewhere else
add(
new DataView(
"expeditionsView",
new ListDataProvider(colonisations)
)
{
@Override
protected void populateItem(final Item item)
{
Expedition expedition = item.getModelObject();
// "item" represents the current "row-component"
item.add(new Label("title", expedition.getTitle());
item.add(new Label("price", expedition.getPrice())
}
}
);
As you can see, you're just populating your table-rows' cells with the
components you need. Instead of Labels you could also add Buttons or
whatever you like.
greetz,
achim

Re: DataView the easy way?
Do I need to do anything special? Will it automatically go through all rows of my Map? When my map is HashMap<Integer,ArrayList> then Expedition will be my ArrayList or whole row, together with int id? I could probably use just a list of ArrayLists if it'd be easier... -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/DataView-the-easy-way-tp3578760p3579147.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: DataView the easy way?
populateItem() gives you one Expedition at a time. You decide how to render it.

Re: DataView the easy way?
Right :)
So I want to start with something like:
add(new DataView("expedition",
MySession.loggedInUser.colonisations) {
});
I am confused how to implement populateItem though...

Re: DataView the easy way?
There are 15+ pages because there are examples for several components in this folder. Just take a look at SimplePage.java and it should become clear how to do it.

DataView the easy way?
Hi, I am trying to make my first DataView and I found an example that does what I want. It's quite confusing though - it takes like 15 pages and classes to do it and I cannot decipher it. http://wicketstuff.org/wicket14/repeater/?wicket:bookmarkablePage=:org.apache.wicket.examples.repeater.SimplePage http://wicketstuff.org/wicket14/repeater/?wicket:bookmarkablePage=:org.apache.wicket.examples.repeater.SimplePage So, any ideas how to do it fast, just on one page? I have a HashTable with ArrayLists [HashTable<Integer, ArrayList<Long>>] that I want to display. Of course I don't know how many rows I will have, that's why I want DataView. I want to display 3 first data from the ArrayList in the map and I want to be able to select rows [so I can delete them by int id]. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/DataView-the-easy-way-tp3578760p3578760.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
