C# Class Smrf.NodeXL.Visualization.Wpf.GraphDrawer

Draws a NodeXL graph onto a collection of Visual objects.
This is used to draw a NodeXL graph in a WPF application. It contains a collection of Visual objects that represent the graph's vertices and edges. Call DrawGraph to draw a laid-out NodeXL graph onto the contained GraphDrawer.VisualCollection.

GraphDrawer does not lay out the graph. You should lay out the graph using one of the provided layout classes before calling .

A GraphDrawer cannot be directly rendered and is typically not used directly by an application. Applications typically use one of two other NodeXL graph-drawing classes:

NodeXLControl, which is a FrameworkElement that wraps a and hosts its . NodeXLControl is meant for use in WPF desktop applications. It automatically lays out the graph before drawing it. NodeXLVisual, which is a Visual that wraps a and hosts its . This is a lower-level alternative to NodeXLControl and can be used anywhere a Visual is more appropriate than a FrameworkElement. Like GraphDrawer, does not lay out the graph before drawing it.

If you do use GraphDrawer directly, rendering the graph requires a custom wrapper that hosts the GraphDrawer. object.
