Hello everyone,
I am brand new to TopBraid and my goal is to build a UI for
an existing ontology file, but I am running into some issues
identifying how to pass selected values from a tree widget to the grid
view. I have modified some of the examples from the SWA Help section,
but I'm going crazy trying to figure out how to get this working. For
example, when someone clicks "Radiation" the results should be filter
from the default view. Any advice would be extremely helpful! I am
having a hard time finding beginner documentation.
My code within UI.Prototype:
<swa:FullScreenBorderLayout arg:westSize="200">
<div class="ui-layout-west">
<swa:Header arg:label="Find Data By Parameter"/>
<swa:Tree arg:dataProvider="swa:ClassTreeDataProvider"
arg:id="classTree" arg:onSelect="swa.loadWithResource('form',
'resource', resource)" arg:root="eso:ScienceParameter"/>
</div>
<ui:loadable class="ui-layout-center" ui:loadId="form">
<swa:ResultSetGrid arg:resultSet="{#
SELECT ?variableName ?parameter
WHERE {
?variableName eso:parameter ?parameter .
?parameter rdfs:subClassOf ?this .
}
ORDER BY (?parameter) }"/>
</ui:loadable>
</swa:FullScreenBorderLayout>
The query in the loadable above can refer to the variable ?resource to
filter its results. So one way (untested) would be to rewrite it as
<ui:loadable...
<ui:if ui:condition="{= bound(?resource) }">
<swa:ResultSetGrid arg:resultSet="{# ... query that depends on
?resource }" />
</ui:if>
</ui:loadable>
The effect of this is that the loadable will remain empty until the
first click on the tree has been made. Your onSelect handler sets the
variable ?resource (second argument of swa.loadWithResource) when the
loadable gets reloaded. Try replacing ?this with ?resource in your
original query.

PS: Yes the documentation needs to be further extended, meanwhile please
feel free to ask here because it gives us some ideas on what beginners
are struggling with.
