• Flex 3 - problem with the selection of an item in the list by default

  How to select an item in the list by default

  default selected item say to index 0

  I tried to stuff like that-

  listid.selectedIndex = somevalueinmyprogram - 1; 0

  but when I debug what I get
  _selectedIndex = 0 selectedIndex = - 1

  and by default is not selected, why so? [I already checked for what is obvious that somevaluefrommyprogram is not equal to 0]

  Help!

  It's a timing issue, as I told you before. As you know flex applications run in Flash Player, and FP works asynchronously, so what happens, is that when you try to put in place the selectedIndex property data is not yet in the dataProvider. What you can do is use the handleCentersListResult and inside of this function the selectedIndex value after completing centersXLC

• ComboBox - updated database with the ID associated with the selected value

  Hello, first off I am a newbie to developing Flash Builder with PHP, so any help would be mucho appreciated.

  I want to update my database with an id associated with a seletcted value in a combobox

  -I'll create a combox and asociate to a data service that retrieves all possible values

  -With the help of selectedItem, I'm able to the value of the ComboBox to the value associated with the default data object

  -To submit, I want to update the database, not with the value directly, but with its associated id.

  -The list of values are a list of locations with a specific id.

  Here is my code

  ComboBox on a form

  "" < s:Form includeIn = "LocationAdd, LocationUpdate"x ="52" y ="320" defaultButton = "auLocnBtn{}">

  "< s:FormItem label = 'provider ID" "" >

  "" < s:ComboBox id = "spidComboBox" selectedItem ="locations.snam{}" includeIn = "LocationUpdate'x ='97" y ="539"

  creationComplete = "comboBox_creationCompleteHandler (event)" labelField ="name" > ""

  " < s:AsyncListView list =" getSplResult.lastResult{}"/ > "

  < / s:ComboBox >

  < / s:FormItem >

  " < s:Button id ="auLocnBtn"label ="Submit"click ="auLocnBtn_clickHandler (event)"label. LocationUpdate ="Update"tag. LocationAdd ="Add"/ > "

  < / s:Form >

  protected function auLocnBtn_clickHandler(event:MouseEvent):void

  {

  Locations.SPID = parseInt (spidComboBox.selectedItem);

  updateLocationResult.token = locationService.updateLocation (rentals);

  }

  This code will move to the selected item, in this case locations.snam. However, getSpl returns two fields - name and id. I want id associated with locations.snam to use to update the database.

  Do this in php and html is really straight forward, because there is a < value > property that allows me to pass the ID. Something similar in flash builder? I spent hours on this... Please don't laugh, I said I was new on FB!

  See you soon,.

  Brian

  Okay understood outside, what I had to do was

  protected function auLocnBtn_clickHandler(event:MouseEvent):void

  {

  Locations.SPID = parseInt (spidComboBox.selectedItem.spid);

  }

  that is the reference object properties... FB with PHP is great!

  This can be closed.

• ComboBox - trying to set the selected item

  I call a remote object that calls the following function to the suite. The returned object is used to fill a form of TextInputs and a ComboBox control - this is a form of change. How can I set the selected item in the ComboBox? I could not get the selectedItem to work, and I do not know the value of the index that corresponds to selectedCompany.CompanyType in order to use selectedIndex.
  
  private void receiveSelectedCompany(event:ResultEvent):void {}
  selectedCompany = event.result as business;
  
  copy the record in the areas of publishing
  txtCompanyId.text = selectedCompany.CompanyID.toString ();
  cboCompanyTypeEdit.selectedItem.CompanyType = selectedCompany.CompanyType;
  txtCompanyName.text = selectedCompany.CompanyName;
  txtCompanyShortName.text = selectedCompany.CompanyShortName;
  txtTaxId.text = selectedCompany.TaxID;
  }
  
  Thanks in advance,
  France
  

  FranceC, here is a function allows you to do.

  simply call the selectComboValue function and pass it the name of the combobox and the search string as follows:

  selectComboValue (Mazonedelistederoulante, dataObj.fieldName.toUpperCase ());

  Here's the function:

  public void selectComboValue(select:_mx.controls.ComboBox,_optionToSelect:String):void {}
  for (var i: int = 0; i< select.dataprovider.length="" ;="" i++)="">
  If (select.dataProvider.getItemAt ( ) .label == optionToSelect) {}
  select.selectedIndex = i;
  break;
  }
  }
  }

  PS: If you are looking for the data rather than on the label simply change this line:
  If (select.dataProvider.getItemAt () .label ==)
  to do this:
  If (select.dataProvider.getItemAt ( ) .data == )

  Dear,

  I use Jdeveloper 12.1.3

  Ashish,

  Yes its simple if there are no other value depend on this attribute.

  In my case this attribute should update other attributes when its selected.

  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:

• 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?

• Spark Combobox with dataprovider is empty

  There seems to be a bug when using a candle with an empty dataprovider combobox.  The idea is to have an empty combobox that adds all entries in the dataprovider for each group entered.  Attached is a simple project to demonstrate.  The first combobox has a dataprovider to the color 'Red', 'green', 'Blue' in it.  No matter what type in the box, whether it's an existing element or a new one, it displays in the label below.

  The second combobox has a dataprovider that is currently empty.  Anything by typing in the box and pressing on enter does absolutely nothing.  There is no way to get the value entered in the combobox control now.

• COMBOX Box not displaying the selected item

  Here is the code I use to try to capture and display the selected item in a ComboBox control:
  
  private void changeProjectTypeSelection(event:Event):void {}
  projectTypeChange.text += event.currentTarget.selectedItem.cboProjectType + "" +.
  event.currentTarget.selectedIndex + "\n";
  }
  
  
  Then the ComboBox:
  < mx:ComboBox fontSize = "12" x = "93" y = "83" width = "110" id = "cboProjectType" dataProvider = "{projectTypeArray}" labelField = "projectTypeName" selectedIndex = "0" click = "changeProjectTypeSelection (event)" > < / mx:ComboBox >
  
  Then the TextInput:
  < mx:TextInput id = "projectTypeChange" "248,95" = x y = "84" width = "121" / >
  
  I know there is something wrong with ActionScript... just have not thought of it. Any suggestions would be greatly appreciated!

  Finally! Here is the solution:

  private void changeProjectTypeSelection(event:Event):void {}
  var i: int;
  for (i = 0; i<>
  If (projectTypeArray.getItemAt (i) .projectTypeName == event.currentTarget.selectedItem.projectTypeName) {}
  projectTypeChange.text = projectTypeArray.getItemAt (i) .projectTypeName;

• Cannot select items from menu top 25% of the window of the browser most of the time.

  Running Windows 7 Pro, on a new HP Ultrabook (2 months) with FF 15.0.1. Several times, selectable items work not, but usually in the 20-30% of the browser window. With the pointer hovering over selections, it does not change to indicate a selectable element, or if it will allow you to select. It happens on sites such as Yahoo!, HP, etc. He doesn't do it all the time, but I'd say at least 50% of the time, even if you reload the page and allow all sites with NoScript.

• How to avoid the default menu items?

  All of hell

  I'm developing an app for BlackBerry handheld.  I add menu items that are specific to the different screens of my application by substituting the makeMenu (.) method. I DON'T want to include default menu items...

  Select Mode
  Page view
  To find
  Copy
  Call 12093...
  12093 SMS...
  12093 MMS...
  Add to Contacts

  Now I do menu.deleteAll () in the first line of the makeMenu (.) method. Suggest me if this isn't the right way?

  It deletes all the elements default menu above.

  Now, in the application, the specific menu item get highlighted based on the next action of logic, that I do a menu.setDefault (menuItem).

  But for the instance when some contact number is selected on the screen (usually 'call' option get highlighted on the menu, but here we have removed) the highlight of the menu according to my works item IS NOT pathological and it always shows the menu first point highlighted.

  I suspect it might be because the default menu items have been added (by program then deleted). That's why I decided to override the onMenu (.) method where I'll call makeMenu (...) to the new instance of the Menu (that are not default menu items), so I'll see the menu using menu.show () and then return true.

  Now by the fix above, the highlight of the menu on my terms item works fine regardless of some contact number is highlighted on the screen or not, BUT the menu is displayed on the upper right and not on the bottom left where it should be.

  This approach is correct, or there is a better way to approach this?

  Thank you

  Mukesh

  OK guys... I had the problem!

  The problem is that if any time a highlighted menu item is removed (as in our case, menu item 'Call' is deleted by menu.deleteAll (()) the priority agenda menu get highlighted. This is just the reason why the first menu item get highlighted if the phone number is selected.

  To fix this, I highlight the appropriate menu option by setting up priority for her.

• How to detect when the selected item ObjectListField changed?

  I expanded the ObjectListField to implement a scroller of marquee style iPod for long lines of text that will disappear from the screen. So far, I have everything works well, and it works as I expect... when it fires.

  I'm having a problem to find a way to make reliable activate. It doesn't seem to be any method I can substitute or any earpiece I can use that fires when the current list item is changed. I first tried setSelectedIndex substitution. That worked sometimes, because apparently the OS is not call setSelectedIndex when he wants to change the item selected, it does something else.

  Then I tried the substitution of navigationMovement and manually call the code to start the timer, but that no longer works (I was the substitution of method navigationMovement of the ListField, maybe I should have done the Manager instead?). But anyway this approach does work for the version of the storm of my application because the storm never calls navigationMovement.

  Then I tried to use a fieldChangeListener, but apparently who don't get fired for the selection.

  Finally in despiration I tried substitution of drawListRow, only qualifying when index equals the selectedRow. But my code of scroll calls invalidate, so of course it just causes a loop infinite drawListRow, slow down the device and not even starting the scroll, because whenever the timer is started, it cancels the old one.

  Anyone have any ideas on what I can do here? Thank you.

  Good end I could not fieldChangeNotify to the fire, no matter which I overrided, even with the first setting the listener. It only seems fair to shoot during the selection change event. One thing to note, I use an objectlistfield, not an ObjectChoiceField... maybe you are thinking as well to another area?

  Thanks for the help anyway, in the end I was able to get the desired effect by modifying the code slightly to reuse the same animation timer rather than create a new one when the selected item changes. The timer is started in the constructor of the ListField. Works very well.

• Selected item

  This code draws my list (ListField)

  County declared as public

  now works

  I got back the index

  You use the unencrypted copy of the config\Core\EqtUIModelDefinitions.xml? If so, you can add the default template for the ActivitySpecRelatedSpecView node.

  Or you can submit an SR for a copy.
