C++ (Cpp) ViewerInstancePtr Examples

Example #1

File: ViewerNode.cpp Project: ebrayton/Natron

ViewerInstancePtr
ViewerNode::getViewerProcessNode(int index) const
{
    if (index >= 2 || index < 0) {
        return ViewerInstancePtr();
    }
    NodePtr node = _imp->getViewerProcessNode(index);
    if (!node) {
        return ViewerInstancePtr();
    }
    return toViewerInstance(node->getEffectInstance());
}

Example #2

File: GuiAppInstance.cpp Project: Kthulhu/Natron

ViewerInstancePtr
GuiAppInstance::getLastViewerUsingTimeline() const
{
    QMutexLocker k(&_imp->lastTimelineViewerMutex);

    if (!_imp->lastTimelineViewer) {
        return ViewerInstancePtr();
    }

    return _imp->lastTimelineViewer->isEffectViewerInstance();
}

Example #3
