Remove HTML5 Canvas specific parts from default topicmap view model

Reported by: jri Owned by: jri
Priority: Major Milestone: Release 4.2
Component: DeepaMehta Standard Distribution Version: 4.1
Keywords: Cc: dgf, Malte, joern
Complexity: 3 Area: Application Framework / API
Module: deepamehta-webclient


The default topicmap view model is supposed to be topicmap renderer agnostic. It is supposed to be reusable by other renderer implementations, e.g. the SVG Topicmap Renderer.

Currently the default topicmap view model relies on a HTML5 Canvas 2D Context in order to measure text (used for wrapping long topic labels).

See Webclient /script/renderers/topicmap_renderers/topicmap_view_model.js

Thanks joern for reporting!

Fixed on Mar 25, 2013:

The default topicmap view model is now renderer agnostic.
It is not coupled to a HTML5 Canvas 2D Context anymore.



  • class is renamed to DefaultTopicmapViewmodel?
  • add_topic() returns the created topic view model (formerly void)
  • add_association() returns the created association view model (formerly void)

Canvas Topic (the topic view model):

  • "truncated_label" is a new property
