  1. Install the "KIELER Layout for GMF" feature from our update site, see Downloads
    • It includes the Java-based layout algorithms developed in the KLay project.
  2. Open a diagram and press the layout button  or use the shortcut Ctrl+R L.

...

The primary API of KIML is the DiagramLayoutEngine, which is responsible for analyzing diagrams, creating a KGraph structure, configuring and executing the layout algorithms, and writing new position information back to the diagram. It is invoked with

Code Block
language
languagejava
themeEclipsejava
DiagramLayoutEngine.INSTANCE.layout(workbenchPart, diagramPart)

...

Each layout option that is registered in the extension point needs a corresponding constant in Java code, where the most relevant data is replicated with a Property constant for easy use in the implementation of layout algorithms. KIML comes with a large set of built-in layout options, which are all defined in LayoutOptions. Layout providers can access the layout option values using the IPropertyHolder interface:

Code Block
languagejava
themeEclipse
languagejava
KShapeLayout nodeLayout = parentNode.getData(KShapeLayout.class);
boolean isInteractive = nodeLayout.getProperty(LayoutOptions.INTERACTIVE);

...


The layout option that is used in this example has a default value, thus it is guaranteed that the option always returns a valid value. This and the fact that properties are type-safe allows us to implicitly cast and unbox the returned value to a boolean without checking for NullPointerExceptions or ClassCastExceptions.
