Detailed Description

pqTimelineItemDelegate draws timeline in cells and add some associated widgets.

This handles connection with the active scene to keep the timelines up to date.

Start and End scene times are editable and can be locked with dedicated button, integrated in the pqTimelineTrack::TIME item.

Constructor & Destructor Documentation

pqTimelineItemDelegate()

pqTimelineItemDelegate::pqTimelineItemDelegate	(	QObject *	parent = nullptr,
		QWidget *	parentWidget = nullptr
	)

~pqTimelineItemDelegate()

pqTimelineItemDelegate::~pqTimelineItemDelegate ( )

override

Member Function Documentation

paint()

void pqTimelineItemDelegate::paint ( QPainter *  painter, const QStyleOptionViewItem &  option, const QModelIndex &  index  ) const

override

Render the timelines.

Depends on the type (time, animation) stored in a custom item role

sizeHint()

QSize pqTimelineItemDelegate::sizeHint ( const QStyleOptionViewItem &  option, const QModelIndex &  index  ) const

override

Reimplemented to change row height.

editorEvent()

bool pqTimelineItemDelegate::editorEvent ( QEvent *  event, QAbstractItemModel *  model, const QStyleOptionViewItem &  option, const QModelIndex &  index  )

override

Reimplemented to handle mouse events.

So we can handle clicking on the timeline to edit start / end time.

eventFilter()

bool pqTimelineItemDelegate::eventFilter ( QObject *  watched, QEvent *  event  )

override

Reimplemented to handle more mouse events from parent view.

editorEvent is useful to get the concerned index and option, but it is pretty restricted. For instance no release event is catched if it occurs outside of the index that received the corresponding press event. Thus we need this eventFilter, to watch the full pqTimelineView.

setActiveSceneConnections

void pqTimelineItemDelegate::setActiveSceneConnections ( pqAnimationScene *  scene )

slot

Set the active scene connections.

updateSceneTimeRange

void pqTimelineItemDelegate::updateSceneTimeRange ( )

slot

Update cache of start/end time of the scene.

needsRepaint

void pqTimelineItemDelegate::needsRepaint ( )
