<g:tab> does not take have a ui:field attribute
I found this in TabLayoutPanel's javadoc:
The children of a TabLayoutPanel element are laid out in <g:tab>
elements. Each tab can have one widget child and one of two types of
header elements. A <g:header> element can hold html, or a
<g:customHeader> element can hold a widget. (Note that the tags of the
header elements are not capitalized. This is meant to signal that the
head is not a runtime object, and so cannot have a ui:field
attribute.)
However your suggestion led me to another solution
I changed
<g:TabLayoutPanel barUnit='EM' barHeight='3'>
<g:tab >
.........
<g:tab>
<g:tab >
.........
<g:tab>
</g:TabLayoutPanel>
to this
<g:TabLayoutPanel barUnit='EM' barHeight='3' ui:field="tabLayout">
<g:tab >
.........
<g:tab>
<g:tab >
.........
<g:tab>
</g:TabLayoutPanel>
Now the parent widget has reference to TabLayoutPanel and I can add
event handlers to it.
I don't like this very much because the parent module holds
tabLayoutPanel's reference and is responsible for adding event
handlers. I would like the individual tabs or the composites they hold
to receive events directly so that the event registration and handling
logic resides within the tab / composite.
Anyway, I have something working for now, I'll see what more can be
done. Thanks!
If anyone has suggestions about making this more modular please write
in!
Thanks,
Priyank
