The LiveView Project Viewer presents a visual overview of a LiveView project, clarifying the relationships between the various components and providing easy access to the configuration information underlying each piece. The Viewer helps you navigate through and understand the components that make up a LiveView project, and provides a collection of wizards that walk you through the steps to create a new project, or to add new components to existing projects.
The canvas area of the Project Viewer contains a directed graph, depicting how data flows through the various project components at run time. To create this graph, the Viewer scans the project's lvconf configuration files to discover the existing LiveView components and the interrelationships between them. While open, the Project Viewer continues to monitor the project's contents, automatically updating its display to reflect any changes in the project's component structure.
The Viewer maintains validation status for each LiveView component, and shows a red border around components to signal validation problems. Hover the mouse cursor over a component to see further a description of the validation issue.
The Viewer provides convenient access to the LiveView configuration or EventFlow module files that define each component:
Select a component, right-click, and select either Open LiveView Component or Open EventFlow Application as appropriate.
Double-click a component to open the LiveView Configuration Editor associated with it.

The LiveView Project Viewer provides access to several wizards to help you create new projects and to add new features to existing projects. A Palette View is associated with the Viewer in the same lower left corner of Studio as the EventFlow Editor's Palette View.
