Inheritance diagram of TaurusLCD
class TaurusLCD(parent=None, designMode=False)[source]

Bases: PyQt5.QtWidgets.QLCDNumber, taurus.qt.qtgui.base.taurusbase.TaurusBaseWidget

A Taurus-enabled Qt.QLCDNumber widget. Its text can represent either the rvalue or wvalue magnitude (or nothing), and the background can colour-code the attribute quality or the device state (or nothing)

DefaultBgRole = 'quality'
DefaultFgRole = 'value'
DefaultModelIndex = None
DefaultShowText = True
bgRole

This property holds the background role. Valid values are ‘’/’None’, ‘quality’, ‘state’

Access functions:

controller()[source]
fgRole

This property holds the foreground role. Valid values are:

  1. ‘’/’None’ - no value is displayed

  2. ‘value’ - the value is displayed

  3. ‘w_value’ - the write value is displayed

Access functions:

getBgRole()[source]
getFgRole()[source]
getModelIndex()[source]
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.

classmethod getQtDesignerPluginInfo()[source]

Returns pertinent information in order to be able to build a valid QtDesigner widget plugin.

The dictionary returned by this method should contain at least the following keys and values: - ‘module’ : a string representing the full python module name (ex.: ‘taurus.qt.qtgui.base’) - ‘icon’ : a string representing valid resource icon (ex.: ‘designer:combobox.png’) - ‘container’ : a bool telling if this widget is a container widget or not.

This default implementation returns the following dictionary:

{ 'group'     : 'Taurus [Unclassified]',
  'icon'      : 'logos:taurus.png',
  'container' : False }
Return type

dict

Returns

a map with pertinent designer information

handleEvent(evt_src, evt_type, evt_value)[source]

very basic and generalistic handling of events.

Override when necessary.

Parameters

  • evt_type (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.

Return type
