14. 14 Slide 14 Marvin Applets and Marvin Beans May 2005 Marvin as a building block

15. 15 Slide 15 Marvin Applets and Marvin Beans May 2005 Marvin Applets Browser-independent solution for integrating Marvin applets into the HTML source: <!– msketch_begin("../..", 460, 380); // arguments: CODEBASE, WIDTH, HEIGHT msketch_param(mol",../structures/benzene.mol); // structure URL as applet parameter // alternatively the structure source can also be specified: msketch_param(mol", c1ccccc1); // structure source as applet parameter msketch_param(colorScheme", cpk); // applet parameter … msketch_end(); //-->

16. 16 Slide 16 Marvin Applets and Marvin Beans May 2005 Applet specific features (1) 1. Both Swing and AWT versions are available for maximum compatibility, the appropriate version for the browser / JRE is automatically selected 2. Signed (trusted) applets enable access to local files, system clipboard and allow printing

17. 17 Slide 17 Marvin Applets and Marvin Beans May 2005 Applet specific features (2) 3. Modularity –Modular loading of packages ensures fast download-time –Modules are not included into the main jar, they are loaded on demand –Preloading of frequently used modules can be specified with applet parameter: msketch_param("preload", "MolExport,Parity,SmilesExport,Clean2D,MyformatExport");

18. 18 Slide 18 Marvin Applets and Marvin Beans May 2005 Applet – JavaScript communication The applet API is accessible from JavaScript, providing a convenient solution to –Fetch the current structure from the applet in a specified file format. This is typically used for sending the structure to the server for further processing. –Change the structure or display options of the applet without reloading the page.

19. 19 Slide 19 Marvin Applets and Marvin Beans May 2005 MarvinView tables on the web Live structures in a HTML page with associated data:

20. 20 Slide 20 Marvin Applets and Marvin Beans May 2005 Marvin Beans Use Marvin Beans to add MarvinSketch or MarvinView as a graphical component to your standalone application Additional API is accessible for –Import / Export –Performing calculations with plugins –2D and 3D cleaning of structures –etc.

21. 21 Slide 21 Marvin Applets and Marvin Beans May 2005 API example : integration www.chemaxon.com/marvin/examples/dialog/DialogLauncher.java.txt JDialog dialog = new JDialog(…); MSketchPane sketcher = new MSketchPane(); dialog.getContentPane().add(sketcher); … Molecule mol= sketcher.getMol(); //getting the sketched molecule Adding a Marvin Sketch component to a dialog: Adding a Marvin View component to a dialog: JDialog dialog = new JDialog(…); MViewPane viewer = new MViewPane(); Molecule mol = …; viewer.setM(0, mol); //setting a molecule to display dialog.getContentPane().add(viewer); Full java source is available at:
