  3. Remember... Magic is easy, once YOUknow the secret! Marshall Brodien Grokking the Paradigm

  4. Overview • To modify menu commands we need to: • Identify the configuration file and JSP to modify • Copy the file to the custom/config directory • Edit the dmfx:actionmenuitem elements and attributes • Refresh the configuration • Similar to customizing the toolbar Grokking the Paradigm

  5. Adding a Menu CommandIdentifying the Files to Modify • The “obvious” place to start is /webtop/config/menubar_component.xml • Copy to /custom/config/menubar_component.xml Grokking the Paradigm

  6. Adding a Menu CommandIdentifying the Files to Modify Note the location of the menubar.jsp (so we can copy it) <component id="menubar" extends="menubar:/webcomponent/config/library/menubar/menubar_component.xml"> ... <pages> <start> /webtop/classic/menubar/menubar.jsp </start> </pages> ... </component> Grokking the Paradigm

  7. Adding a Menu CommandIdentifying the Files to Modify • Change the extends attribute to point to the Webtop file we just copied. • Change the <start> page to a new custom page we’ll modify <component id="menubar" extends="menubar:/webtop/config/menubar_component.xml"> ... <pages> <start> /custom/menubar/menubar.jsp </start> </pages> ... </component> Grokking the Paradigm

  8. Adding a Menu CommandIdentifying the Files to Modify • Copy /webtop/classic/menubar to the /custom directory Grokking the Paradigm

  9. Adding a Menu CommandIdentifying the Files to Modify • menubar.jsp includes menubar_body.jsp <%@ page contentType="text/html; charset=UTF-8" %> <%@ page errorPage="/wdk/errorhandler.jsp" %> <%@ taglib uri="/WEB-INF/tlds/dmform_1_0.tld" prefix="dmf" %> <%@ taglib uri="/WEB-INF/tlds/dmformext_1_0.tld" prefix="dmfx" %> <%@ include file='/webcomponent/library/menubar/menubar_body.jsp' %> Grokking the Paradigm

  10. Adding a Menu CommandIdentifying the Files to Modify • Menubar.jsp includes menubar_body.jsp • Copy the file from /webcomponent/library/menubar to /custom/menubar Grokking the Paradigm

  11. Adding a Menu CommandIdentifying the Files to Modify • Edit /custom/menubar/menubar.jsp to include our custom menubar_body.jsp (same directory) <%@ page contentType="text/html; charset=UTF-8" %> <%@ page errorPage="/wdk/errorhandler.jsp" %> <%@ taglib uri="/WEB-INF/tlds/dmform_1_0.tld" prefix="dmf" %> <%@ taglib uri="/WEB-INF/tlds/dmformext_1_0.tld" prefix="dmfx" %> <%@ include file="menubar_body.jsp" %> Grokking the Paradigm

  12. Adding a Menu Command • Adding a command to a menu (actionmenuitem) follows the same paradigm as adding an actionlink to the toolbar <dmfx:actionmenuitem dynamic="multiselect" name="file_rename" value="Rename" action="rename" /> Grokking the Paradigm

  13. Adding a Menu Command • Slip the new item between the file_saveas command and file_checkin <dmfx:actionmenuitem dynamic='singleselect' id='file_saveas' name='file_saveas' nlsid='MSG_SAVE_AS' action='saveasxforms' showifinvalid='true'/> <!-- Added by Dennis Dawson 11-16-06 --> <dmfx:actionmenuitem dynamic="multiselect" id = "file_rename" name = "file_rename" value = "Rename" action = "rename" /> <dmfx:actionmenuitem dynamic='multiselect' name='file_checkin' nlsid='MSG_CHECKIN' action='checkin' showifinvalid='true'/> Grokking the Paradigm

  14. Adding a Menu Command • The Rename command added to the File menu Grokking the Paradigm

  15. Adding a Menu Command • Enabled when one or more items are selected Grokking the Paradigm

  16. Moving a Menu Command • To move a menu command, change its position in the JSP <dmfx:actionmenuitem dynamic='singleselect' id='file_view' name='file_view' nlsid='MSG_VIEW_FILE' action='view' showifinvalid='true'/> <!-- Added by Dennis Dawson 11-16-06 --> <dmfx:actionmenuitem dynamic="multiselect" id = "file_rename" name = "file_rename" value = "Rename" action = "rename" /> <dmfx:actionmenuitem dynamic='singleselect' id='file_saveas' name='file_saveas' nlsid='MSG_SAVE_AS' action='saveasxforms' showifinvalid='true'/> Grokking the Paradigm

  17. Moving a Menu Command • The Rename command in its new position Grokking the Paradigm

  18. Removing a Menu Command • Comment out a command to remove it from the menu <% /* Removed by Dennis Dawson 11-16-06 <dmfx:actionmenuitem dynamic='multiselect' name='file_cancelcheckout' nlsid='MSG_CANCEL_CHECKOUT' action='cancelcheckout' showifinvalid='true'/> */ %> Grokking the Paradigm

  19. Removing a Menu Command • The Cancel Checkout command removed Grokking the Paradigm

  20. Multiplicitas Componatis Res Simplex • Taken as a whole, Webtop and WDK-based applications are intricate, multifaceted feats of programming • When you focus on any one element of the application, it’s easy to follow the logic and duplicate its behavior • Once you grok the paradigm, enhancing and customizing complex applications becomes a series of simple steps Grokking the Paradigm
