Loading the Molecule into the Diagram Component

INDEX

You must define a project file to tell the diagram component to use the data source. The project file is an XML file called phenol-molecule.idpr. This file contains the class name of the data source, and also the path of the style sheet used to represent the molecule.

Code Sample 2.11 shows the project file contents.

<diagrammer style="molecule.css">
  <datasource class="PhenolMoleculeDataSource"/>
</diagrammer>

To display the molecule, you can simply load the project file into the diagram component as follows:

Diagrammer.setDataFile(new URL("file:phenol-molecule.idpr"));
