Custom widget with custom UiBinder markup

[dparish]

I have a widget that would benefit from custom UiBinder markup (like
DockLayoutPanel)

I've looked through the docs, the source and the web and not found an
example of how this is implemented. Has anyone done this?

I'm looking to do something like this

<custom:mywidget ui:field="widget">
<left><!-your widget></left>
<right><!- your widget></right>
<left><!-your widget></left>
<right><!- your widget></right>
<left><!-your widget></left>
<right><!- your widget></right>
<!- your widget><!- your widget><!- your widget>
</custom:mywidget>

You can use @UiChild, see:

http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/uibinder/client/UiChild.html

That will work. I'd still prefer to use descriptive xml like
DocLayoutPanel. From what I see of @UiChild it just enforces the types
of children it does not allow for quite what I was looking for. (but
probably good enough)

I take that back. UiChild should do it perfect. Good example here:

Add two methods

@UiChild

public void addLeft(Widget w) {...}

@UiChild

public void addRight(Widget w) {..}

Then make sure you widget implements HasWidgets or similar.

In your uibinder you can now use

<custom:mywidget ui:field="widget"> 

<custom:left><!-your widget><custom:/left>  

<custom:right><!-your widget><custom:/right> 

<!- your widget>

Some additional questions in the absence of a full dev guide:

1. What about a class that extends TabLayoutPanel?  I can write and annotate a method addTab(Widget w) in order to use the <xxx:tab> child instead of <g:tab>, but what about the grandchild <g:header> that the <g:tab> could have had?

2. Can the first parameter to the annotated method be a subclass of Widget to restrict the possible types?
