Spark Combobox with dataprovider is empty

• ComboBox with dataprovider HTTPService

  What I currently have is a comboBox that uses an httpservice dataprovider that sends xml data. I got this to work and it brings in my list. What I can't seem to find out is how to reference the selected data or label to make combobox then.
  
  The data should be similar to:
  < departments >
  Department < and > ALL < / Department >
  Department < and > accounting < / Department >
  Department < and > Administration < / Department >
  Department < and > Engineering Services < / Department >
  Department < and > Engineering Technology < / Department >
  Department < and > business technology < / Department >
  < service > HR < / Department >
  Department < and > information systems < / Department >
  Department < and > copy < / Department >
  < / departments >
  
  and the flex code is:
  < mx:HTTPService
  ID = "deptData".
  URL = "dept_xml.php" / >
  
  and the combobox control:
  < mx:ComboBox id = dataProvider = "{deptData.lastResult.departments.department"deptCombo"}" width = "200" / > "
  
  I tried all sorts of things like deptCombo.selectedItem.data, deptCombo.selectedItem.label deptCombo.selectedItem.department, but I can't figure out what to do to make it work.

  It is sometimes simple solutions that escape us. I tried to use deptCombo.text just to see and that worked. :)

• ComboBox with customized with buttons listcell

  Hi all

  I would like to create a combobox with a custom listview that contains several controls. The thing is that setAction is consumed by the list of ComboBox popoup and then controls inside are ignored.

  There is here an example:

  How could I do 'System.out.println ("work of Does´t");' works?

  A ComboBox control is used to select an element; from a set of predefined items (displayed in the context menu), or possibly by entering one. You intend something must be selected in your control? If so, it is not clear if something should be selected when the user presses the button. If this isn't the case, then a ComboBox control is not the appropriate control. Something like a menu button can work better.

  Assuming you want to use it to make a selection, a menu button might work if you used CustomMenuItems points the menu button and hideOnClick set to false:

  import java.util.Arrays;

  import javafx.event.EventHandler;

          List options = Arrays.asList("Option 1", "Option 2");
          MenuButton menuButton = new MenuButton("Options");
          for (String option : options) {
              menuButton.getItems().add(createCustomMenuItem(option));
          }
          StackPane root = new StackPane();
          root.getChildren().add(menuButton);
          Scene scene = new Scene(root, 300, 250);
          primaryStage.setTitle("Hello World!");
          primaryStage.setScene(scene);
          primaryStage.show();
      }
  
      private CustomMenuItem createCustomMenuItem(String option) {
          HBox hbox = new HBox(5);
          hbox.getChildren().addAll(createButton(), createButton(), new Label(option));
          CustomMenuItem customMenuItem = new CustomMenuItem(hbox);
          customMenuItem.setHideOnClick(false);
          return customMenuItem ;
      }
  
      private Button createButton() {
          final Button btn = new Button("Hola");

      }
  
      public static void main(String[] args) {

  If you do not want 'selection '. You should maybe use a button from menu above and manage the selection yourself.

• Creation of ComboBox with the values of the fields

  Hey everyone, it's been a while since my last post.

  I spent some time trying to fill a ComboBox with the values of the 3 fields of different form of google and I was wondering if someone could tell me on common sense.

  Thanks a lot for any idea!

  the general idea would be something like this:

  Get added to a table field values

  var aItems = [];

  aItems.push (getField("Text1").valueAsString);

  aItems.push (getField("Text2").valueAsString);

  aItems.push (getField("Text3").valueAsString);

  Fill the drop-down list with the elements box

  getField("combo1").setItems (aItems);

  Replace domain names with real field names that you use.

  You can start the list with an element that is a single space (if it appears empty) or something like "- select -". You can also make sure you add all the duplicate entries, which would happen if all the field values are the same.

• ComboBox with default selected item

  Hello

  I try to view combobox with an item selected by default. Is it possible to use instead of selectedIndex selectedItem to achieve?

  Here is the code and I want User2 to be selected by default:

  <? XML version = "1.0" encoding = "utf-8"? >
  " < = xmlns:mx mx:Application ' http://www.Adobe.com/2006/MXML "layout ="absolute"xmlns:local =" * "> "
  < mx:HBox id = "box" >

  < mx:String > user3 < / mx:String >
  < / mx:dataProvider >
  < / mx:ComboBox >

  Please let me know if this is possible?

  Thank you

  You must pass a String OBJECT as a selectedItem.

  following code works:

• Fill Combobox with nested XML

  Hello!
  How can I fill a ComboBox with an XML retrieved via a HTTPService?
  
  My XML looks like
  
  <? XML version = "1.0" encoding = "iso-8859-1? >
  < xml >
  < node label = value '1' = 'a' / >
  < node label = value "2" = "b" >
  < node label = "21" value = "ba" / >
  < node label = '22' value = 'bb' / >
  < node label = "23" value = "bc" / >
  < / node >
  < node label = '3' value = 'c' / >
  < node label = "4" value = "d" / >
  < node label = '5' value = 'e' / >
  < / xml >
  
  The output you want in the drop-down list would be
  
  one
  b
  -ba
  -bb
  Colombia-British
  c
  d
  e
  
  < mx:ComboBox id = "selectedLevel" dataProvider = labelField 'structure of {}"="label"/ >
  
  'structure' is an XMLListcollection, looks like my Resulthandler
  
  structure = new XMLListCollection (event.result.node);
  
  
  Can someone give me a hint what is missing?

  Thank you.

• Fill ComboBox with XML data

  I would like to fill a ComboBox with data in a simple xml file like this. It's probably quite newbie question, but I couldn't find the answer to the search in this forum and the documentation up to date.

  option 1 < item > < / item >
  option2 < item > < / item >
  Option3 < item > < / item >
  < / root >
  
  
  I would be very grateful if someone tell me how the ComboBox control to retrieve data from XML file. Thank you!

  I found a way to do it. Here is the code I use to populate a ComboBox control with dynamically loaded XML data (the XML content is in the first post).

• ComboBox with checkbox

  Hi all

  I want to display a combobox with the ablity to select multiple items and also be able to show the elements selected with different visual effects - I think that a checkbox to display selected/United Nations-selected item is more appropriate, but I can live with the alternative, like for example, highlight them selected with 'light green' etc.

  Is it possible to do so under JavaFX?

• Creating a ComboBox with ActionScript

  I can't create a ComboBox with ActionScript. I want just a simple list, I can add and subtract.

  My Code:

  var inventory: ComboBox = new more.

  Error messages:

  Scene 1, Layer ' Layer 1 ', 1 environment, line 142 1046: Type was not found or is not a constant of compilation: ComboBox. "

  Scene 1, Layer ' Layer 1 ', 1 environment, line 142 1180: call to a method may not set ComboBox. "

  I don't know where I am going wrong. I found several example on the net which was code similar to mine, and some suggested adding the following:

  import fl.controls.ComboBox;
  
  That didn't work either and gave me more errors. Any suggetions?
  
  Thanks.
  

  I should have mentioned to keep this import line.

• Fill a ComboBox with actionscript

  I'm currently learning Flash 8 Pro by working my way through a book "Teach Yourself Flash 8' and met an teaching example that does not work." The (very basic) THAT the code needs to fill three lines of a ComboBox (with the instance name "MaZoneDeListeDéroulante"). I rechecked the syntax against that in the tutorial and it fits precisely. However, test results the film in errors such as:
  
  * Error * scene = scene 1, layer = Layer 1, frame = 1:Line 3: there is no method with the name "removeAll.
  and
  * Error * scene = scene 1, layer = Layer 1, frame = 1:Line 4: there is no method with the name "addItem".
  
  Can someone help a total Flash beginner who is unsure whether the error is in the tutorial or in its own implementation of it? Or even if there is something wrong with my installation of Flash? I'm learning this step tiny stuff at a time and I'm not convinced to go ahead until I have this problem to be resolved. Shaky foundations and all that.
  
  Thanks in advance.
  
  Here's the code AS I use:
  
  

  It is resolved. Turns out that I needed to delete the ASO files. I would have never known about this on my own, so thanks a lot go to the author, Phillip Kerman for her help.

• Auto expand Spark Datagrid rowcount with dataprovider

  I have problems with a datagrid used within a VGroup.

  I put the datagrid view to display a line + the header with the requestedRowCount = - 1

  who says it has auto extend if several lines are added.

  When a filter is applied, I have reset the requestedRowCount number of rows + 1 (for header).

  monitoring indicates that the code is running

  However the datagrid lines never change.

  Is it because I'm not using the properties correctly or because it's within a VGroup?

  Any suggestion would be greatly appreciated... of the code snippets below...

  

  // Filter Rentals by Job
  if (arrRentalsByJob.filterFunction == null) arrRentalsByJob.filterFunction = filterByJob;
  trace('Rentals Done');
  arrRentalsByJob.refresh();
  if (arrRentalsByJob.length == 0) {
     trace('adjusting rentals to min - num rentals = ' + arrRentalsByJob.length.toString());
     // Set the DataGrid row count to the array length, plus one for the header.                    
     dgRentalSummary.requestedRowCount = 2;
  } else {
     trace('adjusting rentals to handle num rentals = ' + arrRentalsByJob.length.toString());
     dgRentalSummary.requestedRowCount = arrRentalsByJob.length + 1;
  }
  
  dgRentalSummary.invalidateDisplayList();
  

  <s:DataGrid id="dgRentalSummary" width="811" height="48" dataProvider="{arrRentalsByJob}" editable="false" requestedRowCount="-1" rowHeight="20">
  <s:columns>
    <s:ArrayList>
      <s:GridColumn dataField="rentalCompany" headerText="Rental Company" width="230"></s:GridColumn>
      <s:GridColumn dataField="rentalEquipment" headerText="Rental Equipment" width="500"></s:GridColumn>
      <s:GridColumn dataField="rentalCost" headerText="Cost" labelFunction="displayHours"></s:GridColumn>
  </s:ArrayList>
  </s:columns>
  </s:DataGrid>               
  

  Found the problem - using the tip of a previous post.

  Impossible to actually define a first 'height' for the DataGrid - and I don't need to set the number of lines when I filter.

  So... it works...

  // Filter Rentals by Job
  if (arrRentalsByJob.filterFunction == null) arrRentalsByJob.filterFunction = filterByJob;
  trace('Rentals Done');
  arrRentalsByJob.refresh();if (arrRentalsByJob.length == 0) {   dgRentalSummary.requestedRowCount = 2;} else {   dgRentalSummary.requestedRowCount = arrRentalsByJob.length + 1;}dgRentalSummary.invalidateDisplayList();
  
  

• A new spark ComboBox item does not appear in textInput?

  I played with s:ComboBox and generally like them a lot. A detail is driving me crazy if is - most likely due to my lack of knowledge in this matter - that if I try to add a new item to my dataprovider in a changeHandler (recorded for the change event) the text for the ComboBox, textInput disappears - while adding item works perfectly. Interestingly enough the same operation works very well if it is called by clicking on a button, that is after the change event has been processed and the text does not disappear. To better understand what I'm talking about check out the code of http://help.adobe.com/en_US/flex/using/WS70f0d54f063b9b081aac8d1d1247252e4a0-8000.html#WS7 0f0d54f063b9b08626480d2124725f692c-7fff

  try to add a new item and press ENTER. Taking the same code of myCB_changeHandler and to use it as a button click event instead of a change event handler gives the behavior that I'm looking, i.e. the new element appears in the field of textInput CB and when clicking on the button added to the data provider while does not disappear from the textInput. Is there a way to accomplish this same behavior in the change event handler?

  Thank you!
