modelChanged

This method is called, whenever the underlying NodeModel has changed. Hence, in this method the data to be visualized is retrieved from the NodeModel. Then the data is interpreted by the view, i.e. converted in a component or drawn. The NodeModel is accessible via the getNodeModel method. If you have to call this method frequently you can override this method and have your derived NodeModel as the return type of the overridden method.

Example #1:

protected void modelChanged() {
    ExampleNodeModel nodeModel = (ExampleNodeModel)getNodeModel();
    // retrieve the data to visualize...
    Object viewModel = nodeModel.getViewModel();
    // set it to spacialized panel implementation
    // to interprete the model and visualize it
    m_panel.visualizeModel(viewModel);
}
