It's the latter, though for what we're wanting to do I don't think
AbstractEditableCell is what we want.
What we want to do is bring a name per line in one cell that's
clickable similar to ClickableTextCell for every object of a sub-list
from the model object.
For instance if we had the following two classes:
public class Foo {
private List<Bar> bars;
private String something;
public List<Bar> getBars() {
return bars;
}
public String getSomething() {
return something;
}
}
public class Bar {
private String name;
public String getName() {
return name;
}
}
Then we define a cellTable / Column as so:
...
CellTable<Foo> table = new CellTable<Foo>();
Column<Foo, String> somethingColumn = new Column<Foo, String>(new
TextCell()) {
public String getValue(Foo object) {
return object.getSomething();
}
};
table.addColumn(somethingColumn);
// Here's the ideal part + some pseudo code
Column<Foo, String> barNames = new Column<Foo, String>(new
CompositeCell<Foo, String>(HasCell<ClickableTextCell, String>()) {
public String getValue(Foo object) {
for (Bar b: object.getBars()) {
return b.getName();
}
}
};
table.addColumn(barNames);
And finally the output would be something like:
| Something Header | Bar Header |
-------------------------------------------------
| Cool Stuff | Bar 1 |
| | Bar 2 |
| | Bar 3 |
-------------------------------------------------
| More stuff | Bar 7 |
...
