wx.lib.pubsub.core.topicdefnprovider.TopicTreeSpecPrinter

Helper class to print the topic tree using the Python class syntax. The “printout” can be sent to any file object (object that has a write() method). If printed to a module, the module can be imported and given to pub.addTopicDefnProvider(module, ‘module’). Importing the module also provides code completion of topic names (rootTopic.subTopic can be given to any pubsub function requiring a topic name).

Class API

class TopicTreeSpecPrinter

Helper class to print the topic tree using the Python class syntax. The “printout” can be sent to any file object (object that has a write() method). If printed to a module, the module can be imported and given to pub.addTopicDefnProvider(module, ‘module’). Importing the module also provides code completion of topic names (rootTopic.subTopic can be given to any pubsub function requiring a topic name).

Methods

__init__(self, rootTopic=None, fileObj=None, width=70, indentStep=4, treeDoc=defaultTopicTreeSpecHeader, footer=defaultTopicTreeSpecFooter)

For formatting, can specify the width of output, the indent step, the header and footer to print to override defaults. The destination is fileObj; if none is given, then sys.stdout is used. If rootTopic is given, calls writeAll(rootTopic) at end of __init__.

---

getOutput(self)

Each line that was sent to fileObj was saved in a list; returns a string which is '\n'.join(list).

---

writeAll(self, topicObj)

Traverse each topic of topic tree, starting at topicObj, printing each topic definition as the tree gets traversed.
