Inserting a node on an element empty < af:tree > via the context Menu


My requirement is to create a tree node by using the option "Insert" through the context menu when the component of the tree is empty. By clicking on the option insert a node should be created in the tree. But currently the context menu don't appear unless a node exists in the tree of.


JDeveloper Version: 11.1.1.7.0

Fig - context menu to insert added to the Tree component

Fig - context menu is not display when no available tree node

The component of the tree grabs only necessary to render space and only in this space, you can access the context menu. As you do not have a jet of node, the space to make the tree is very small or didn't exist at all.

You can add a showPopupBehavior (pointing to the popup of context menu) to FY: tree which should give you the popup anywhere in the tree.

    Hello

    I created a small diagram to test, and indeed you cannot use the Insert create items in the design, but you can do it in Source view.

    To be even easier that I did was to take this scheme which had only a root with a choice and added another element like a father (so I added another level). Like this, you are able to use the Insert, and if you see the code that is generated after doing, in the Source, you'll have what you need.

  • "Edit in Photoshop Elements" missing from the context menu of windows.

    How can I get the 'Edit in Photoshop Elements' in my context menu? I think what happened was that after installation of PSE 13 I uninstalled PES 12 and who removed the context menu item. Just guessing. Is it possible to add it without reinstalling PSE 13?

    Right-click on a photo file of the type you want to open in PSE. In the context menu, right-click Open with to open the menu. Select "Choose default program" and in the window that opens, select PSE 13 if it appears in recommended or other. If it is not displayed, select Browse and navigate to the PSE 13 .exe file in programs/Adobe/Photoshop Elements. If you want the files of this type to be always open to post-secondary studies when double-clicked, check the box "always use the selected program." If you want to PSE 13 only appear in the open with menu, make sure that the box is not checked. Click OK.

  • 'Get link' the context menu element gone

    Why is that if you save a template with the template repository that corresponds to a url, your menu item appears and the default menu item "Get link" disappeared?

    JDE 4.5

    8330 (Simulator)

    Default CDMA network

    If methods both PatterRepository that StringPatternRepository seem to make the menu option 'Get link' system disappear if you save a model that recognizes a url.

    The way I had the time is (finally!) pretty simple really: (may not be perfect)

    1. in your screen class (extends screen), override the method "makeMenu (menu Menu, for example int).

    2. remove your custom menu item.

    3. determine which control has the focus (if you care about that).

    4 loop through each of the menu items after you call super.makeMenu (menu, for example) and look for a menu item that contains the text "get link".  (I guess if "Get link" then it's a kind of matching url)

    5 get the text underlined/matched and do something with it as if it matches a particular value or what not, add your menu item.

    Example (proof of concept):

    protected void makeMenu(Menu menu, int instance) {
       MenuItem m = null;
       String url = "";
    
       super.removeMenuItem(_MyCustomUrlDoSomethingMenuItem);
       super.makeMenu(menu, instance);
    
       if (_SomeGlobalVariableForAControl.isFocus()) {
          //if you care about what control has focus
          for (int i = 0; i < menu.getSize(); i++) {
             m = menu.getItem(i);
             if ((m != null) && (m.toString() != null) && (m.toString().trim().toLowerCase().equals("get link"))) {
                 //this is the "Get Link" system menu item (I hope!)
                 url = _SomeGlobalVariableForAControl.getUnderlinedUrl();
                 menu.add(_MyCustomUrlDoSomethingMenuItem);
                 return;
             }
          }
       }
    }
    
    //to get the underlined text
    class CustomControl extends ActiveAutoTextEditField {
       public CustomControl(...) { ... }
       public String getUnderlinedUrl() {
          if (regionHasCookie()) {
             String url = getRegionText(getRegion());
             if (url == null) { return ""; }
             return url;
          } else {
             return "";
          }
       }

  • Context menu of tabs on the empty tab bar.

    When click with the right button on a zone empty of the tab bar, I get a pop-up menu to select the toolbars that I want to show off or customize the layout of Firefox. As I recall (and my muscle memory seems to agree) that used to bring up the context menu of the tab instead, allowing me to re - open closed tabs and others. Is it possible to restore this functionality?

    The tab bar is a regular toolbar in the current version of Firefox (on this subject, you can place buttons on toolbar) and right click on the empty space will open the context menu of the toolbar.

    You must right-click on a tab to get the context menu of the tab.

    Is it possible that when the new record is inserted in a table then this empty inserted record is automatically displayed without scrolling?

    Because I change the size property of the table 5 range and my new record is inserted at no 10.

    When I click the addRecord button the new parallel line does not appear, do scroll down to see it.

    I want that we don't have to scroll down.

    The line is displayed automatically.

  • insertion of swf file in dw vs complete creation of the site in flash

    I am updating a Web site and am quite familiar w/html and DreamWeaver, but I'd like to add some elements of the Flash on the site.  I'm using Flash CS4.

    What is the advantage and / drawback to insert several SWFs in my site DW versus just creating the entire site in Flash. What is the difference between the two approaches?

    If I do the latter, I have subsequently put in DW anyway so this is an html file?

    Thanks for your help!

    There may be potential problems with Flash content in a web site since the iStuff evolution leads to reject Flash content to display.  If you are looking to attract mobile users, then go with Flash can be a gamble, especially as you go more down in the future where there will be more development Flash Player align with the mobile market.

    I've heard say that Flash does not support the handicapable design elements with the html/css integration.

    You can still have control of web page for availability of the Flash Player code, and if not found contained alternative present instead.

    A problem of having a full Flash site is that it can be less SEO friendly to go with straight based on designed html, although given that Flash content may still reside in an html page there are some measures that can be taken to support the SEO concerns.

    For a full Flash site design, you would probably not need DW since Flash can generate its own html page.

    I recommend that you ask your questions in the Dreamweaver forum as well.  The reaction it to content using Flash is likely to be hard, so don't take it personally, but some useful information might still be gleamed to try.
