Class GraphViewerUtils

java.lang.Object
ghidra.graph.viewer.GraphViewerUtils
public class GraphViewerUtils extends Object
This class houses various methods for translating location and size data from the various graph coordinate spaces. Graph Spaces Size and location information is represented in multiple coordinate spaces, as listed below. To translate from one to the other, use GraphViewerUtils; for example, to see if a mouse click is on a given vertex.
  • Layout Space - the layout contains Point2D objects that represent positions of the vertices.
  • Graph Space - the space where the Layout points are transformed as the view is moved around the screen (e.g., as the user pans)
  • View Space - the coordinate system of Java 2D rendering; scaling (zooming) transformations are applied at this layer

Note: vertex relative means that the value is from inside the vertex, or the vertex's coordinate space (like a component that is inside the vertex), where it's coordinate values are relative to the component's parent.
