Detailed Description

SPV3D_CADSelection handles various selection modes available on RenderViews.

Simply create multiple instances of SPV3D_CADSelection to handle selection modes for that RenderView. SPV3D_CADSelection uses internal static members to ensure that at most 1 view (and 1 type of selection) is in selection-mode at any given time.

SPV3D_CADSelection()

SPV3D_CADSelection::SPV3D_CADSelection	(	QObject *	parent,
		pqRenderView *	view,
		SelectionMode	mode
	)

If view is nullptr, this reaction will track the active-view maintained by pqActiveObjects.

References Mode, MousePosition, ObserverIds, PreviousRenderViewMode, setRepresentation(), setView(), updateEnableState(), and View.

~SPV3D_CADSelection()

SPV3D_CADSelection::~SPV3D_CADSelection ( )

Member Function Documentation

actionTriggered

void SPV3D_CADSelection::actionTriggered ( bool  val )

virtualslot

For checkable actions, this calls this->beginSelection() or this->endSelection() is val is true or false, respectively.

For non-checkable actions, this call this->beginSelection() and this->endSelection() in that order.

References beginSelection(), and endSelection().

beginSelection

void SPV3D_CADSelection::beginSelection ( )

privateslot

starts the selection i.e.

setup render view in selection mode.

References ObservedObject, ObserverIds, onLeftButtonRelease(), onMouseMove(), onRightButtonPress(), onRightButtonRelease(), PreviousRenderViewMode, and View.

cleanupObservers()

void SPV3D_CADSelection::cleanupObservers ( )

private

cleans up observers.

References ObservedObject, and ObserverIds.

endSelection

void SPV3D_CADSelection::endSelection ( )

privateslot

finishes the selection.

Doesn't cause the selection, just returns the render view to previous interaction mode.

References cleanupObservers(), CurrentRepresentation, PreviousRenderViewMode, and View.

fastSelection()

void SPV3D_CADSelection::fastSelection ( bool  presel = false )

private

makes fast selection.

References CurrentRepresentation, Mode, MousePosition, SELECT_EDGES, SELECT_FACES, SELECT_SOLIDS, SELECT_VERTICES, and View.

getSelectionModifier()

int SPV3D_CADSelection::getSelectionModifier ( )

private

References View.

onLeftButtonRelease()

void SPV3D_CADSelection::onLeftButtonRelease ( )

private

callback called for click events when in 'interactive selection' modes.

References fastSelection().

onMouseMove()

void SPV3D_CADSelection::onMouseMove ( )

private

callback called for mouse move events when in 'interactive selection' modes.

References DisablePreSelection, fastSelection(), SPV3D_Prs::FromVtkIdToEntry(), and Representation.

onRightButtonPress

void SPV3D_CADSelection::onRightButtonPress ( )

privateslot

Disable preselection during rotation using the right button.

References DisablePreSelection.

onRightButtonRelease

void SPV3D_CADSelection::onRightButtonRelease ( )

privateslot

References DisablePreSelection.

selectionChanged()

void SPV3D_CADSelection::selectionChanged ( vtkObject *  , unsigned long  , void *  calldata  )

private

callback called when the vtkPVRenderView is done with selection.

References endSelection(), getSelectionModifier(), and View.

SetMode()

void SPV3D_CADSelection::SetMode

(

const SPV3D_CADSelection::SelectionMode

mode

)

Set the selectionMode.

References Mode.

setRepresentation

void SPV3D_CADSelection::setRepresentation ( pqDataRepresentation *  representation )

privateslot

Called when the active representation changes.

References endSelection(), Representation, RepresentationConnection, and updateEnableState().

setView

void SPV3D_CADSelection::setView ( pqView *  view )

privateslot

Called when this object was created with nullptr as the view and the active view changes.

References endSelection(), and View.

updateEnableState
