TaurusValueComboBox

class TaurusValueComboBox(parent=None, designMode=False)

This widget shows a combobox that offers a limited choice of values that can be set on an attribute.

Import from taurus.qt.qtgui.input as:

from taurus.qt.qtgui.input import TaurusValueComboBox

addValueNames(names)

Add new value-name associations to the combobox.

… seealso: setValueNames()

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.

Returns:

True if autoApply is enabled. False otherwise

Return type:

bool

findData(data, **kwargs)

Reimplemented from Qt.QComboBox.findData() to accept the extra pymatch keyword arg. If pymatch is True, the match will be attempted using python’s == operator. This is required to bypass some limitations imposed by C++’s QVariant . By default, pymatch is False and behaves just as Qt.QComboBox.findData()

forcedApply

whether forcedApply mode is enabled or not.

Returns:

True if forceApply is enabled. False otherwise

Return type:

bool

classmethod getQtDesignerPluginInfo()

reimplemented from TaurusBaseWritableWidget

getValue()

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

getValueString(value, default='UNKNOWN(%s)')

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)

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

model

Returns the model name for this component.

Parameters:

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

Returns:

the model name.

Return type:

str

postDetach(*, key='')

reimplemented from TaurusBaseWritableWidget. The key argument is there for API compatibility, but it is ignored byt the current implementation

preAttach(*, key='')

reimplemented from TaurusBaseWritableWidget. The key argument is there for API compatibility, but it is ignored byt the current implementation

setModel(m, **kwargs)

Reimplemented from TaurusBaseWritableWidget.setModel()

setQModel(*args, **kwargs)

access to QCombobox.setModel()

setValue(value)

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

setValueNames(names)

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)')

Makes a label object change the displayed text by the corresponding value of the combobox. This is implemented for the general case and may be not what you expect in some cases (as for example, it fires a fake periodic event which may be problematic if these are being filtered out).

updateStyle()

reimplemented from TaurusBaseWritableWidget

useParentModel

(deprecated))

writeIndexValue(index)

slot called to emit a valueChanged signal when the currentIndex is changed (and trigger a write if AutoApply is enabled)
