question: access to topicmap model from within a xyz_plugin.js

[Malte]

on clientside, when extending the webclient (from within a xyz_plugin.js)

a) is there any possibility to get access to the data model (all topics/assocs or topicids/associd) of the currently visible topicmap?

b) and are "hidden" topics also part of that model?

I assume this is a ticket of type "Question"?

thanks for your help!

No, for the moment that's not possible. The topicmap model is private. I'll fix that quickly.

Would it be sufficient if you could get an topic/assoc iteration for iterating one-by-one?
And yes, the "hidden" topics would be accessible too (the map model has a per-topic "visibility" state).

[Malte]

yep, any kind of access would be fine for me. thank you very much.

Topicmaps module: expose topicmap model (#147).

A plugin can access the model of the selected topicmap:

    // get selected topicmap
    var topicmap = dm4c.get_plugin("topicmaps_plugin").get_topicmap()
    //
    // iterate through topics
    topicmap.iterate_topics(function(topic) {
        // access the topic's properties:
        topic.id
        topic.type_uri
        topic.label
        topic.x
        topic.y
        topic.visibility    // boolean: true=visible, false=hidden
    })
    //
    // iterate through associations
    topicmap.iterate_associations(function(assoc) {
        // access the association's properties:
        assoc.id
        assoc.type_uri
        assoc.topic_id_1
        assoc.topic_id_2
    })

See ticket 147.
