yFiles Tutorial Demos for Hierarchical Layout

This package contains tutorial source code demos that showcase various aspects of the yFiles hierarchical layout facilities.

Class	Description
demo.layout.hierarchic.IncrementalHierarchicLayouterDemo	Shows how to use IncrementalHierarchicLayouter together with sophisticated customized view modes.
demo.layout.hierarchic.SwimlaneGroupDemo	Shows the effect of combining IncrementalHierarchicLayouter's support for grouping and swim lanes.
demo.layout.hierarchic.IncrementalHierarchicGroupDemo	Shows how to use IncrementalHierarchicLayouter on nested graphs.
demo.layout.hierarchic.IncrementalHierarchicFoldExpandDemo	Shows how to use IncrementalHierarchicLayouter to update nested graphs after interaction.
demo.layout.hierarchic.LayerConstraintsDemo	Shows how to apply layer constraints when calculating hierarchical layouts.
demo.layout.hierarchic.PortCandidateDemo	Shows how to control the connecting points of edges on nodes during automatic layout.
demo.layout.hierarchic.SankeyDemo	Shows how a Sankey diagram can be produced by means of the incremental hierarchic layout algorithm.
demo.layout.hierarchic.SequenceConstraintsDemo	Shows how to apply sequence constraints when calculating hierarchical layouts.
demo.layout.hierarchic.SimpleSwimlaneLayouterDemo	Demonstrates the swim lane feature of the IncrementalHierarchicLayouter.
demo.layout.hierarchic.SimpleIncrementalHierarchicLayouterDemo	Shows three variants how to use IncrementalHierarchicLayouter: from scratch, from sketch or incrementally.
demo.layout.hierarchic.HierarchicLayouterDemo	Demonstrates various aspects of the HierarchicLayouter.
demo.layout.hierarchic.CriticalPathDemo	Demonstrates how to align the nodes of a critical path such that the interconnecting edges can be routed in a straight, vertical fashion.
demo.layout.hierarchic.CellSpanLayoutDemo	Demonstrates how to combine multiple cells in a partition grid for more freedom on node placement.
demo.layout.hierarchic.CellSpanActionFactory	Creates all user actions for the `CellSpanLayoutDemo`, most notably the action for switching from design mode to diagram mode. When doing so, a `y.view.tabular.TableLayoutConfigurator` subclass converts colored cell spans into group nodes which in turn are interpreted as multi-cells by `demo.layout.hierarchic.GroupNodeTransformerStage`.
demo.layout.hierarchic.GroupNodeTransformerStage	Interprets group nodes directly contained in a table group node as multi-cells for the purpose of placing the other nodes assigned to the corresponding partition grid cells.

Running the Demos

From Within an IDE

Set <yFilesDir>/src as your source directory. Then add <yFilesDir>/lib/y.jar and the source folder <yFilesDir>/src to your classpath. Now you should be ready to compile and run all executable demo classes.

With Ant

First make sure you have the build tool Ant installed on your system. Now you can use the demo build script build.xml located in <yFilesDir>/src/demo to launch each demo by specifying its simple class name as a target. Alternatively, launch the interactive demo driver by specifying run as target to conveniently access all demos.
