class TrivialUI.GenericProxy(data, children, parent=None, row=0)

The proxy object makes a single piece of Python data navigable in a tree context. This is the base class that uses Template Method to allow various different sorts of Python data to be navigated in this way.

hasChild(row)

Check whether this dict has an entry for the specified row. In fact, this just checks whether the number of entries in the collection is sufficient.

class TrivialUI.DictProxy(data, children, parent=None, row=0)

Proxy object for making a dict of dicts navigable in a form usable by PyQt.

This gives nondeterministic ordering, unless you use an OrderedDict.

class TrivialUI.ListModel(data, header=None)

A model object that exposes the model interface that Qt expects, based on a bunch of data provided as (possibly nested) Python list objects.

The tree structure itself is built up inside of the ListProxy object stored as self.root_item. The tree is constructed on the fly as Qt queries using the index() method.

TrivialUI.MainWindow

alias of <Mock id='140603074489808'>

class TrivialUI.TextEdit(name)

Proxy class for creating a QLineEdit. This has to be a distinct class for two reasons:

• It’s used in static initialisation when creating a MainWindow class, so it ends up being constructed before the Qt application is ready.
• Similarly, it’s used statically where we actually want multiple instances to be created when the MainWindow is created.
