Method Details

__init__(self, node_info)
(Constructor)

source code 

Initialize the NodeItem instance.

Parameters:
Overrides: object.__init__

data(self, role)

source code 
Overrides: PyQt4.QtGui.QStandardItem.data

addConfig(self, cfg)

source code 

Add the given configurations to the node.

Parameters:
  • cfg (str) - the loaded configuration, which contains this node.

remConfig(self, cfg)

source code 

Remove the given configurations from the node.

Parameters:
  • cfg (str) - the loaded configuration, which contains this node.

type(self)

source code 
Overrides: PyQt4.QtGui.QStandardItem.type

newNodeRow(self, name, masteruri)
Class Method

source code 

Creates a new node row and returns it as a list with items. This list is used for the visualization of node data as a table row.

Parameters:
  • name (str) - the node name
  • masteruri (str) - the URI or the ROS master assigned to this node.
Returns: [NodeItem, QtGui.QStandardItem(Cofigurations), QtGui.QStandardItem(Node URI)]
the list for the representation as a row

__eq__(self, item)
(Equality operator)

source code 

Compares the name of the node.

Overrides: PyQt4.QtGui.QStandardItem.__eq__

__gt__(self, item)
(Greater-than operator)

source code 

Compares the name of the node.

Overrides: PyQt4.QtGui.QStandardItem.__gt__
