Is this <http://www.gwtproject.org/doc/latest/DevGuideUiBinder.html#Hello_Widget_World> not enough? Buried too deep? Lacking examples and/or a step-by-step?
In order to use a set of widgets in a ui.xml template file, you need to tie their package to an XML namespace prefix. That’s what’s happening in this attribute of the root <ui:uibinder> element: xmlns:g='urn:import:com.google.gwt.user.client.ui'. This says that every class in the com.google.gwt.user.client.ui package can be used as an element with prefix g and a tag name matching its Java class name, like <g:ListBox>. See how the g:ListBox element has a visibleItemCount='1' attribute? That becomes a call to ListBox#setVisibleItemCount(int) <http://www.gwtproject.org/javadoc/latest/com/google/gwt/user/client/ui/ListBox.html#setVisibleItemCount-int->. Every one of the widget’s methods that follow JavaBean-style conventions for setting a property can be used this way.
