Detailed Description

pqSelectionManager is the nexus for introspective surface selection in paraview.

It responds to UI events to tell the servermanager to setup for making selections. It watches the servermanager's state to see if the selection parameters are changed (either from the UI or from playback) and tells the servermanager to perform the requested selection. It is also the link between the server manager level selection and the GUI, converting servermanager selection result datastructures into pq/Qt level selection datastructures so that all views can be synchronized and show the same selection in their own manner.

Member Function Documentation

getSelectedPort()

pqOutputPort* pqSelectionManager::getSelectedPort

(

)

const

Returns the first currently selected pqOutputPort, if any.

getSelectedPorts()

const QSet<pqOutputPort*>& pqSelectionManager::getSelectedPorts

(

)

const

Return all currently selected pqOutputPort as a QSet, or an empty QSet if there aren't any.

hasActiveSelection()

bool pqSelectionManager::hasActiveSelection

(

)

const

Return true if there is at least one currently selected pqOutputPort false otherwise.

selectedDataBounds()

vtkBoundingBox pqSelectionManager::selectedDataBounds

(

)

const

Returns the bounding box for all the selected data.

selectionChanged

void pqSelectionManager::selectionChanged ( pqOutputPort *  )

signal

Fired when the selection changes.

Argument is the pqOutputPort (if any) that was selected. If selection was cleared then the argument is nullptr.

clearSelection

void pqSelectionManager::clearSelection ( pqOutputPort *  outputPort = nullptr )

slot

Clear selection on a pqOutputPort.

Calling the method without arguments or with nullptr will clear all selection

setActiveView

void pqSelectionManager::setActiveView ( pqView *  )

slot

Used to keep track of active render module.

select

void pqSelectionManager::select ( pqOutputPort *  )

slot

Updates the selected port.

onSourceAdded

void pqSelectionManager::onSourceAdded ( pqPipelineSource *  )

slot

Set up signal/slot from the pipeline source to the selection manager.

onSourceRemoved

void pqSelectionManager::onSourceRemoved ( pqPipelineSource *  )

slot

Disconnect signal/slot from the pipeline source to the selection manager.

expandSelection

void pqSelectionManager::expandSelection ( int  layers, bool  removeSeed = false, bool  removeIntermediateLayers = false  )

slot

Expand/contract the selection to include additional layers.

This cannot shrink the initial selection seed. Set layers to control the number of layers to expand/contract from current selection Set removeSeed to remove the initial selection seed Set removeIntermediateLayers to remove intermediate expand layers

onSelect()

void pqSelectionManager::onSelect ( pqOutputPort *  , bool  forceGlobalIds  )
