Hey Isaac,
Thanks for that information. Based on that let me know what I have
below is correct
public class TestTableModel extends TableModel<MyBean>
{
// code to initialize the RPC service - possibly in a constructor?
public void onRequest()
{
// code to use the use the service and make a call
service.requestRows(request, new
AsyncCallback<SerializableResponse<MyBean> result>>() {
public void onFailure(Throwable caught)
{
//do something
callback.onFailure(new Exception....)
}
public void onSuccess
(SerializableResponse<MyBean> result)
{
callback.onRowsReady(request, result);
}
});
}
}
public class MyTableDemo
{
public TesttableModel myTableModel = null;
public void onModuleLoad()
{
// code to create/initialize tables
....
scrollTable = createScrollTable(headerTable, dataTable,
footerTable);
// to retrieve the data remotely and store in the table created
scrollTable.getTableModel().onRequest();
}
public void createScrollTable(.....)
{
myTableModel = new TestTableModel();
TableDefinition<MyBean> myTableDef = createTableDefinition();
MyScrollingTable<MyBean> myScrollTable = new MyScrollingTabel
(myTableModel, dataTable, headerTable, myTableDef);
myScrollTable.setFooterTable(footerTable);
}
// the other usual code continues
}
I thought it best to give some sort of example to see if what I'm
thinking is right. Above you see that I created my own TableModel from
the existing one.
Additionally, I showed the snippet of code where the table model is
added to the scroll table in the TableDemo class.
And finally in the onModuleLoad method you can see the tableModel
being accessed and being called to retrieve the data remotely. Is that
right?
I'm guessing somewhere the onRowsReady method would need to be
implemented by me? Where would that be? If it isn't expected to be
implemented by me, then
how would I end up creating a table when my bean has other objects in
it as opposed to only primitive data.
Hope that gives you an idea of where my confusion is, since its at
about 3 places i think :)
Thanks again
Suri
