I am trying to learn about GWT, took your example and have it
working ok. I tried to do a simple extension to it and have been
running into problems and wondered if you or anyone else might
be able to help?
I thought I'd try to output the height of the image in much the same
way
as you are outputting the url and name, so I added a label:
<g:Label text="{failWhaleImage.getName}" />
<g:Label text="{failWhaleImage.getHeight}" /> <!-- added by me! -->
This fails because getHeight provides an int, not a String.
My next thought was to create a UiField to represent the label and in
the
java code, get the height from the data, convert to String and call
SetText()
on the label:
<g:Label text="{failWhaleImage.getName}" />
<g:Label ui:field="heightLabel"/> <!-- added by me! -->
The step that I didn't know how to make (or even if it is possible) is
to reference the ui:data field from within the Java code to make the
getHeight() call, or access the height attribute. Is this possible?
Thanks,
Pete
