Returns:

The class object corresponding to the type of Taurus model this widget handles or None if no valid class is found.

setContextMenu(menu)

Context Menu must be a list of tuples (ActionName,ActionMethod), empty tuples insert separators between options.

setModel(model, **kwargs)

Sets/unsets the model name for the given key. If key is MLIST, a model is set for each name in the model sequence, new model keys are automatically added to the object’s modelList attribute and the corresponding models are attached using those keys. The new keys are of the form (MLIST, i) where i is the index of the corresponding model name in the model sequence.

Parameters:

• model (str (or sequence of str if key is MLIST)) – the new model name. If key is MLIST, model is expected to be a sequence of model names.

• key (object) – the model key. Defaults to first element of .modelKeys

setName(name)

updateStyle()

Method called when the component detects an event that triggers a change in the style.
