Bases: taurus.qt.qtgui.tree.taurustree.TaurusBaseTreeWidget

A class:taurus.qt.qtgui.tree.TaurusBaseTreeWidget that connects to a taurus.core.taurusauthority.TaurusAuthority model. It can show the list of database elements in four different perspectives:

  • device : a three level hierarchy of devices (domain/family/name)
  • server : a server based perspective
  • class : a class based perspective

Filters can be inserted into this widget to restrict the tree nodes that are seen.

DftPerspective = 3
KnownPerspectives = {3: {'label': 'By device', 'icon': 'applications-system', 'tooltip': 'View by device tree', 'model': [<class 'taurus.qt.qtcore.model.taurusdatabasemodel.TaurusDbDeviceProxyModel'>, <class 'taurus.qt.qtcore.model.taurusdatabasemodel.TaurusDbDeviceModel'>]}, 'PlainDevice': {'label': 'By plain device', 'icon': 'applications-system', 'tooltip': 'View by plain device tree (it may take a long time if there are problems with the exported devices)', 'model': [<class 'taurus.qt.qtcore.model.taurusdatabasemodel.TaurusDbDeviceProxyModel'>, <class 'taurus.qt.qtcore.model.taurusdatabasemodel.TaurusDbPlainDeviceModel'>]}, 8: {'label': 'By server', 'icon': 'application-x-executable', 'tooltip': 'View by server tree', 'model': [<class 'taurus.qt.qtcore.model.taurusdatabasemodel.TaurusDbServerProxyModel'>, <class 'taurus.qt.qtcore.model.taurusdatabasemodel.TaurusDbServerModel'>]}, 2: {'label': 'By class', 'icon': 'text-x-script', 'tooltip': 'View by class tree', 'model': [<class 'taurus.qt.qtcore.model.taurusdatabasemodel.TaurusDbDeviceClassProxyModel'>, <class 'taurus.qt.qtcore.model.taurusdatabasemodel.TaurusDbDeviceClassModel'>]}}
getModelClass()[source]

Return the class object for the widget. Default behavior is to do a ‘best effort’ to determine which model type corresponds to the current model name. Overwrite as necessary.

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