addValueNames(names)[source]

Parameters:names (sequence <tuple>) – A sequence of (name,value) tuples, where each attribute value gets a name for display
autoApply

whether autoApply mode is enabled or not.

Return type:bool
Returns:
forcedApply

whether forcedApply mode is enabled or not.

Return type:bool

classmethod getQtDesignerPluginInfo()[source]

reimplemented from TaurusBaseWritableWidget

getValue()[source]

Get the value that the widget is displaying now, not the value of the attribute.

getValueString(value, default='UNKNOWN(%s)')[source]

Returns the corresponding name in the combobox out of a value (or a default value if not found).

Parameters:
  • value – value to look up
  • default (str) – value in case it is not found. It accepts a ‘%s’ placeholder which will be substituted with str(value). It defaults to ‘UNKNOWN(%s)’.
keyPressEvent(event)[source]

reimplemented to trigger a write when Enter (or Return) key is pressed

model

Returns the model name for this component.

Return type:str
Returns:the model name.
postDetach()[source]

setModel(m)[source]

Reimplemented from TaurusBaseWritableWidget.setModel()

setQModel(*args, **kwargs)[source]

access to QCombobox.setModel()

setValue(value)[source]

Set the value for the widget to display, not the value of the attribute.

setValueNames(names)[source]

Sets the correspondence between the values to be applied and their associated text to show in the combobox.

Parameters:names (sequence <tuple>) – A sequence of (name,value) tuples, where each attribute value gets a name for display
teachDisplayTranslationToWidget(widget, default='UNKNOWN(%s)')[source]

Returns whether this component is using the parent model

Return type:bool
Returns:True if using parent model or False otherwise
writeIndexValue(index)[source]
