Adding list sub-editors to tab panel - gwt

Question

I use ListEditor to allow editing list of chilren and I do everything just like I saw in some examples.The only difference from examples is that I want widgets editing children to be added as a tabs to some TabLayoutPanel.
The problem is that I want to give a header to this new tab and this header is not constant but depends on object being edited by newly created sub-editor (so let the header be child.getName()) which I don't know inside EditorSource#create() method.
ListEditor<ChildProxy, ChildPanel> children = ListEditor
.of(new EditorSource<ChildPanel>() {
#Override
public ChildPanel create(int index) {
ChildPanel tab = new ChildPanel();
//here's a problem, how I can get tabHeader here?
tabPanel.add(tab,tabHeader);
}
});
How can I set value-dependent headers to tabs created by create()? Any help/workaround would be greatly appreciated.

Answer 1

Does this approach work for you :
public class ChildrenEditor extends Composite implements
IsEditor<ListEditor<Child, ChildInTabEditor>> {
ListEditor<Child, ChildInTabEditor> editor;
public ChildrenEditor() {
initWidget(uiBinder.createAndBindUi(this));
editor = ListEditor.of(new ChildInTabEditorSource());
}
private class ChildInTabEditorSource extends EditorSource<ChildInTabEditor> {
public ChildInTabEditor create(int index) {
ChildInTabEditor tab = new ChildInTabEditor();
// here's the trick :
Child child = editor.getList().get(index);
tabPanel.add(tab,child.getTabTitle());
return tab;
}
}
#Override
public ListEditor<Child, ChildInTabEditor> asEditor() {
return editor;
}
}
ChildInTabEditor must be a Tab that implements Editor<Child> then too!

What worked for me was passing tabPanel and index to newly created ChildPanel() and make it ValueAwareEditor. Then on setValue() I was setting header on tabPanel reference at given index.
