[news.eclipse.modeling.gmf] Re: Enable the "export" of the diagram

[Cayla Sha <cayla_sha@xxxxxxx>]

Hello Cristian,

I do this in my editor: In my diagram I can right-click on my 
*.xxx-file, choose Export, choose my own Export-Wizard and then the data 
from the diagram is saved in two xml-files in my own xml-Format.

For that you need to build your own Wizard:
In the plugin.xml add the extension point "org.eclipse.ui.exportWizards".
Then I created 3 classes in ...diagram.part: An ExportWizard (extends 
Wizard implements IExportWizard), an ExportPage (extends WizardPage) and 
an ExportHandler (extends DefaultHandler).
On the ExportPage I ask the user for the file-paths (where he wants the 
two xml-files). The Wizard starts the Page, takes the file-paths and 
passes them to the Handler. The Handler is a SAX-Parser, which parses 
the gmf-file and creates on-the-fly two new DOM-Trees. The Wizard takes 
the ready DOM-Trees from the Handler, serializes them, puts them into 
Files and saves them in the FileSystem.

Have fun! ^^
Best wishes
Julia
