Filling of data by clicking on an item in the tree

I have a tree like

TreeItem < String > itemClient = new TreeItem < String > ("customer");
itemClient.setExpanded (false);

TreeItem < String > itemClient1 = new TreeItem < String > ('Place Order');
itemClient.getChildren () .add (itemClient1);
TreeItem < String > itemClient2 = new TreeItem < String > ("Change Order");
itemClient.getChildren () .add (itemClient2);
TreeItem < String > itemClient3 = new TreeItem < String > ("Cancel Order");
itemClient.getChildren () .add (itemClient3);

last item TreeItem < String > itemVendor = new TreeItem < String > ("seller").
itemVendor.setExpanded (false);

last item TreeItem < String > itemVendor1 = new TreeItem < String > ('Place Order');
itemVendor.getChildren () .add (itemVendor1);
TreeItem < String > itemVendor2 = new TreeItem < String > ("Change Order");
itemVendor.getChildren () .add (itemVendor2);
TreeItem < String > itemVendor3 = new TreeItem < String > ("Cancel Order");
itemVendor.getChildren () .add (itemVendor3);


TreeItem < String > rootNode = new TreeItem < String >("");
rootNode.getChildren () .addAll (itemClient, itemVendor);


TreeView < String > tree = new TreeView < String > (rootNode);
tree.setShowRoot (false);

vbox.getChildren () .addAll (tree);
tree.getSelectionModel () .setSelectionMode (SelectionMode.SINGLE);


This tree is placed to the left of the pane border. I want to fill something in the center when it is clicked.

I have different data for each of the element tree.
Any idea on how to achieve this?

Just add a Stanley to the selection model.

tree.getSelectionModel().selectedItemProperty().addListener(new ChangeListener>() {
   @Override
   public void changed(ObservableValue> observable, TreeItem oldValue, TreeItem newValue) {
      System.out.println("Selection: " + newValue);
      // Add your stuff here
   }
});

  • Adding items to the tree in an effective way

    Hello

    I am trying to add items in the tree.

    The problem I am facing is, I have to update the tree constantly and add elments.

    To add first items bit it takes less time, but as the tree grows the accumlated gets.

    Demo Vi is attached for reference.

    Any HELP WILL BE GREATFUL. (vi ATTACHED IS in 2009 version)

    First of all, 1% for calibration of time Windows is 'no difference '.

    But indeed, the update of the front panel is not the factor limiting here: this is the number of children-entries that create problems. So with zero children (as I did in my first test), to postpone the updates done grant you a huge performance increase as is the one and only overhead.

    In your case (100 children), defer updates is disabled the relevance as the method 'Add items' takes awhile.

    I agree that the performance impact is huge, maybe too big, to increase the number of children. But on the other hand, you must understand that you are dealing with arrays of cluster... is in fact a big effort for the memory manager to allocate enough memory, copy of things around and (internally) the deallocation of memory. It's the more data, the most important, this will create. Therefore, it will get slower the more data that you add. But certainly, the measure is surprisingly high.

    But nothing you can change.

    To the last comment: why do you need a tree that changes many times during execution while maintaining several 100ths of elements in any combination of parent/child?

  • Sort the items in the tree manually

    I am trying to allow the user a way to move through the items in a tree 2 levels deep. This will give the user the possibility to order the items within the tree, so they can be sent to the word in the desired order. I have working code to get through the items at the lowest level, but I can't that it works correctly for items in folder level. I have a code that works very well, but he has a little problem. I found that if you stay with moving a folder to the top of the tree then you do not experience the problem. However, if you switch to another folder to move then you will experience the problem earlier. The problem seems to be a copy of a part of the tree and add at the end. I don't know, what's happening! I was hoping that someone could help me with that.

    Does anyone know a way to do this? Oh yes and I wish that property selectedIndex to stay with the folder selected as well.

    Thanks for your help.

    It can be done, Sephiroth did a drag ' n drop component
    to sort items in a component of the tree.

  • Select multiple items in the tree programmatically

    What is the approach recommended for selection by program several elements in a tree? There is an API on the model of selecting either TreeView.getSelectionModel () .select (t, object) to select a single item, but it is not an equivalent API to select multiple items, i.e. TreeView.getSelectionModel (.select(T...objects)).

    One approach is to expand the tree and iterate through all nodes and calculate the index of each item to be selected and then call the method TreeView.getSelectionModel ().selectIndices(int...indices).
    In my case, I want only the records that contain the selected items to be developed for an additional step is to browse all folders and the collapse of those that do not contain the selected items.

    Is there an easier approach?

    Thank you.
    Stefan

    Don't do what suggests Zonski! :-)
    These lists are read-only - you will quickly get a runtime exception.

    The best approach is to just a multiple selection to be on and then loop through the desired selection list, by selecting each element individually. Because multiple selection is enabled, select calling repeatedly will not erase the previous selection.

  • I would like to open my window cookies while being able to click on other items in the "options"?

    When I browse, I like to keep my 'cookies' window opens, so that when I finished my session, I can simply delete all new cookies that appeared at the bottom of the list. While below "youtube.com" is deleted, and I don't lose one of my saved cookies. However, in the latest version of firefox, I can't understand how to leave the window opens independently of the rest of the menu 'options' 'cookies '. In other words, if I am browsing and need to go to 'options' for a reason, as in 'security' or 'content' or one of the other options, the 'cookies' Panel disappears, and all these cookies I wanted to remove easily at the end of my session mingle alphabetically with the rest of them, which means I have to go through the entire list looking for cookies to be deleted. It's boring. This means that I must try to remember to remove all unwanted cookies, every time I have to use the menu options for a reason any. I much prefer how firefox has always dealt with this in the past and I don't really like how it handles this in the new version. Is it possible to change his behavior like her without having to return to a previous version of firefox?

    From topic: config [type in the address bar] can switch browser.preferences.inContent false, then restart Firefox.

  • Windows Explorer ' does not ' when we R-click the item in the files pane

    Now here's a strange: for a few months my Windows Explorer has been "stoppage of work" and "restart" (except that it isn't) in two circumstances. (1) right click on an item in the pane of the files (except a right-click 'Computer', that works to display a context menu.) (2) selection of a file in the files pane, and access to the menu 'File' in the menu bar, either by clicking on it or by using the ALT, then F keyboard shortcut sequence.

    I was about to have Windows reinstalled by my dealer to fix this problem, but since it would involve further tedious re-installing all my applications etc. I thought that I would try to fix it myself.

    I found that the problem disappears once I delete an icon on desktop - any icon will do. So I've set up a collection of "sacrificial icons" on the desktop for this purpose. Should be deleted after each new startup.

    Anyone got an explanation?

    Thank you. This is a useful tip for general use which can be useful in the future, but you will enjoy the simple trick to delete a desktop icon makes my Windows Explorer works for almost no time and effort, and because I don't have the time to spend creating a user profile (with no guarantee that it will actually fix it) since I am very busy and you want to just my computer to work for me I will continue with my little trick.

    I posted this mainly because it's so weird, I thought that folk would like to meditate on this.

  • Items in the list does not appear under the current name?

    Hello

    I use the model 12 and by using the vertical sidebar list. When I click on an item in the list that I want to make current and the rest non-current, but when I discovered the source of each of them is still displayed with a class of "t12noncurrent".

    That's what my model looks like under the definition of the model:

    For "current model list.
    <tr style="padding-bottom: 5px;"><td><a class="t12current" href="#LINK#">#TEXT#</a></td></tr>
    and for "related model list.
    <tr style="padding-bottom: 5px;"><td><a class="t12noncurrent" href="#LINK#">#TEXT#</a></td></tr>
    No idea why its not current selection?

    Hello

    It is not part of the model but the definition of the list itself. Go to select the shared components, lists, your list, and then select a list entry. Here, you should have an input section of the current list with two parameters:

    Current entry list for Pages Type: value "Colon delimited list Page.
    The current list entry for Condition: enter the page number (which should be identical to the Page parameter in the target section)

  • Impossible to delete previously selected items from the drop-down lists at the click of the button Reset on a page of the screen.

    Hello

    I'm unable to clear previously selected items from the drop-down lists at the click of the button Reset on a page of the screen. The code I did to clear the previous value when the click on the button Reset is as below.

    {} public void onReinitialize (ActionEvent actionEvent)

    System.out.println ("onReinitialize is called ::");

    UIComponent uiComp = actionEvent.getComponent ();

    If (uiComp is nothing)

    {

    otherwise we use the button that we linked to that bean

    uiComp = getButtonResetByBean ();

    _logger.info ("reset fields: buttonID =" + uiComp.getId ());

    }

    on the other

    {

    _logger.info ("reset fields: CompID =" + uiComp.getId ());

    }

    Pass the component inside the uniforms, UIXForm, UIXSubform, UIXRegion, UIXPopup, RichCarousel

    or RichPanelCollection that contains the components to reset

    getTextIDLOV () .setValue (null);

    ResetUtils.reset (uiComp);

    }

    ---

    Using this code Iam able to clear the entrance to the text box but can not clear previously selected items from the drop-down lists when the reset button is clicked

    Can anyone please help on this issue.

    It's simple, you can set GenerateIsNullClauseForBindVars = "false" in the viewCriteria who created in EmployeeView

    After doing that it will fill the list of employees only after the Department selection

  • For the last two weeks, when I click on an item in Daily Kos, it does not open, but rather a box pops up saying "allow" that I have to click. -What happened?

    Daily Kos is a site that collects over the web and passes them along. To read the articles, I click it in the list. Suddenly, about 2 or 3 weeks ago, when I clicked on an item, the page came in white with a small block in the upper right corner, saying "allow." Now I have to click "allow" every time, instead of just go to the item when I click on it. What's past and how to fix it?

    Enable the redirection page...? Many users seems to be turned on an accessibility function accidentally. To disable the block of redirection, you can use the Panel Advanced preferences page:
