Changeset 326 for trunk/web/addons/job_monarch/libtoga.php

Timestamp:

Author:

Message:

web/addons/job_monarch/overview.php:

• make our own datasource
• store the XML data in a session for the clusterimage
• assign a image map of clickable nodes for the clusterimage

web/addons/job_monarch/templates/overview.tpl:

• add node_clustermap imagemap block

web/addons/job_monarch/libtoga.php:

• simplify DataSource? constructor
• DataGatherer? no longer creates it's own DataSource? so that global XML data may be used
• assign clustername to NodeImage?'s constructor
• added getImagemapArea to NodeImage?
• added get width/height to NodeImage?
• added setNoimage to ClusterImage? to prevent image output while still processing NodeImage?'s
• added getImagemapArea to ClusterImage? to get entire imagemap
• modified DataGatherer? calls to use supplied DataSource?

web/addons/job_monarch/image.php:

• added retrieval of XML data from session for big ClusterImage?
• changed small ClusterImage? and HostImage? to supply their own DataSource? to DataGatherer?
