- class TaurusLed(parent=None, designMode=False)[source]
A widget designed to represent with a LED image the state of a device, the value of a boolean attribute or the quality of an attribute.
Import from
taurus.qt.qtgui.display
as:from taurus.qt.qtgui.display import TaurusLed
- DefaultFgRole = 'rvalue'
- DefaultModelIndex = None
- DefaultOffColor = 'green'
- DefaultOnColor = 'green'
- fgRole
This property holds the foreground role. Valid values are:
‘value’ - the value is used
‘w_value’ - the write value is used
‘quality’ - the quality is used
Access functions:
- getModelIndexValue()[source]
Called inside getDisplayValue to use with spectrum attributes. By default not used, but some widget might want to support this feature.
Override when needed.
- handleEvent(evt_src, evt_type, evt_value)[source]
very basic and generalistic handling of events.
Override when necessary.
- Parameters
evt_src (object or None) – object that triggered the event
evt_type (taurus.core.taurusbasetypes.TaurusEventType or None) – type of event
evt_value (object or None) – event value
- isReadOnly()[source]
Determines if this component is read-only or not in the sense that the user can interact with it. Default implementation returns True.
Override when necessary.
- Returns
whether or not this component is read-only
- Return type
bool
- model
This property holds the unique URI string representing the model name with which this widget will get its data from. The convention used for the string can be found here.
Access functions:
TaurusBaseWidget.getModel()
TaurusBaseWidget.resetModel()
See also
- modelIndex
This property holds the index inside the model value that should be displayed
Access functions:
See also
- offColor
This property holds the preferred led color This value is used for the cases where the model value does not contain enough information to distinguish between different Off colors. For example, a bool attribute, when it is False it is displayed with the off led but when it is true it may be displayed On in any color. The prefered color would be used in this case.
Access functions:
- onColor
This property holds the preferred led color This value is used for the cases where the model value does not contain enough information to distinguish between different On colors. For example, a bool attribute, when it is False it is displayed with the off led but when it is true it may be displayed On in any color. The prefered color would be used in this case.
Access functions:
- setModel(m)[source]
Sets/unsets the model name for this component
- Parameters
model (str) – the new model name
- setOffColor(color)[source]
Sets the preferred led off color
- Parameters
status (str) – the new off color
- setOnColor(color)[source]
Sets the preferred led on color
- Parameters
status (str) – the new on color
- useParentModel
This property holds whether or not this widget should search in the widget hierarchy for a model prefix in a parent widget.
Access functions:
TaurusBaseWidget.getUseParentModel()
TaurusBaseWidget.setUseParentModel()
TaurusBaseWidget.resetUseParentModel()
