Detailed Description

QAbstractItemModel implementation for vtkDataAssembly.

pqDataAssemblyTreeModel builds a tree-model from a vtkDataAssembly. The vtkDataAssembly to shown is set using setDataAssembly. To allow user-settable check-states, use setUserCheckable(true). The model doesn't support any additional custom properties. One is expected to use a proxy model to store additional meta-data associated with nodes.

setDataAssembly()

void pqDataAssemblyTreeModel::setDataAssembly

(

vtkDataAssembly *

assembly

)

Get/Set the vtkDataAssembly to represent in this model.

dataAssembly()

const

setUserCheckable()

void pqDataAssemblyTreeModel::setUserCheckable

(

bool

)

Get whether the model is user-checkable.

userCheckable()

bool pqDataAssemblyTreeModel::userCheckable ( ) const

inline

Get whether the model is user-checkable.

setCheckedNodes()

void pqDataAssemblyTreeModel::setCheckedNodes

(

const QStringList &

paths

)

Get/Set the check state for Qt::Checked for nodes selected using the path names specified.

Note

checking a node causes all it child nodes to be checked as well.

checkedNodes() may not returns exactly the same paths passed to setCheckedNodes even if the check-states were not changed in between the two calls.

checkedNodes()

QStringList pqDataAssemblyTreeModel::checkedNodes

(

)

const

Get/Set the check state for Qt::Checked for nodes selected using the path names specified.

Note

checking a node causes all it child nodes to be checked as well.

checkedNodes() may not returns exactly the same paths passed to setCheckedNodes even if the check-states were not changed in between the two calls.

QAbstractItemModel interface implementation.

parent()

data()

QVariant pqDataAssemblyTreeModel::data ( const QModelIndex &  index, int  role  ) const

override

QAbstractItemModel interface implementation.

flags()

Qt::ItemFlags pqDataAssemblyTreeModel::flags ( const QModelIndex &  index ) const

override

QAbstractItemModel interface implementation.

setData()

bool pqDataAssemblyTreeModel::setData ( const QModelIndex &  index, const QVariant &  value, int  role  )

override

QAbstractItemModel interface implementation.

modelDataChanged

void pqDataAssemblyTreeModel::modelDataChanged ( int  role )

signal

This signal is fired in setData if the data is changed.

setData can result in multiple calls to dataChanged signal as the data is updated on nodes in the hierarchy. This signal is fired only once for setData call irrespective of how many internal nodes are updated.
