• Setting the focus to a specific index

  Let's say I'm a manager of vertical field with 5 buttons fields. Is it possible to move the focus to a specific field click?

  For example, clicking on the 2nd button will move the focus to the 4th button. Possible?

  Yes, you can set the focus...

  Try this...

  ' Public Sub fieldChanged (field field, int context)
  {
  If (MyButtonField instanceof Field)
  {
  If (Field == VFM.getField (1))
  {
  (VFM.getField (0)) .setFocus () (ButtonField);
  }
  }
  }

  This will focus on the ground in the 1st row on the click event of the button 2nd...

  Similarly, you can write changeListner event for all fields.

  This is a fairly common problem: placement of a DisplayObject property has the value NULL until it has been added to the display list.  There are a few solutions, but the easiest for you would be, if this object never will be added to the display list once.

  // in place of your existing stage.focus line
  addEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
  
  ...
  
  private function onAddedToStage(e:Event):void {
      removeEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
      stage.focus = input;
  }
  

• How to set the focus on the field?

  This is my screen:

  image //add by function (thread)

  RichText //add by function (thread)

  button_next //add by function (thread)

  button_back //add directly on-screen

  I already manage the display as above

  but my problem is the firsttime I get my screen is my focusable on button_back.

  I want to set the focus on image when I get the screen.

  no idea what I need to do?

  they are all put under the focus name, I just don't want to when I go to the screen, focus on button_back

  your back button is added directly to the screen

  and the rest are added by the threads,

  so son take some time to complete that work and until then the button "return" is added

  all your work, once you can do--

  image. SetFocus();

  and you will get the focus on the desired position

• How to set the focus after initialization?

  Problem: I have a problem affecting a new text field to the development after its initialization.

  Background: I've created a form with a table that creates a new line after leaving the last cell/textfield in the last line if necessary. Once I get the label off the last field, emphasis is more completely - that is to say, tab does not reach any other part of the form.

  Tests: I tried to set the focus on the first field of the new line to the help text (rowNum is a variable for the newly created line)

  xfa.host.setFocus (".form1 form [0] of xfa [0] [0].") #subform [0]. Subform2 [0]. Table 1 [0]. Row1 [rowNum]. TextField1 [0] ");"

  and

  this.parent.parent.Row1 [rowNum]. TextField1.setFocus ();

  I also tried to set the focus to the last field that I had left with just

  xfa.host.setFocus ("this");

  Also, I tried to use of the generator of the action to restore the focus to the textfield object newly created when it is initialized.

  [edit] I forgot to say that the attempt to set the focus to the last field that I had left just actually worked. [/ Edit]
  

  Post edited by: jasotastic81

  Looks like you used the variable a literal string... must concatenate the value of the variable in the expression of SOM:

  xfa.host.setFocus (".form1 form [0] of xfa [0] [0].") #subform [0]. Subform2 [0]. Le1 tab [0]. Row1 ["+ rowNum + '"]. TextField1 [0] ");"

  Note the name of two + around the variable to its value with the rest of the chain.

  Let us know if that helps.

• Setting the focus to textfield - cannot type

  I'm trying to use a MouseEvent.CLICK event to set the focus to a TLFTextField and let the user type:

  var textField:TLFTextField = menuField.getTextField ();

  textField.stage.focus = textField;

  textField.setSelection (0,0);

  However, when this code executes, the cursor appears in the textfield, but the user cannot type. What can I do to fix this? A more detailed description below:

  I am applying that has many fields, that the user must fill. The fields are generated dynamically and not always the same number, so I made a movieclip called now and wrote a class so he could manage the feature.

  Now has two areas of text, which are TLFTextFields to the inside of the container MovieClips. The first region, lblFieldName, is the label of the field (for example "name:"). The second is the editable text area lblFieldValue the TLFTextFields are inside containers because I found if I tried to put the lblFieldNametext of now 's manufacturer, it would reset immediately (TextFields are apparently not intitialized until the manufacturer of their parent is over...)

  The size and position of lblFieldValue is defined dynamically depending on the size of lblFieldName. The text in lblFieldValue begins in white until the user enters something. Unfortunately, regardless of the width of the textfield, if the text is empty the user select the textfield by clicking the left edge of it, which is completely unrealistic. My solution has been to add a mouse CLICK event to the set now and try to set the focus to the lblFieldValue TextField. But once again, when the previous code is running it places the cursor but does not allow the user to type. I don't know that I'm missing something simple. Any suggestions?

  Problematic are tlf textfields.  unless you have a good reason to use them, you must use classic text.

• Set the focus to the text box of the embedded NumericStepper control

  I have an application that requires I use NumericStepper edit control as ItemEditor of a DataGrid column.

  I have two problems that I can't seem to overcome, one being the result of the solution to another:

  (1) I need to instantiate the component NumericStepper during execution, because I don't ' know advance what columns it will require.  More important still, I need to specify default attributes (styles, min, max, width, etc.).  I can't understand how to specify these attributes other than in a .mxml file.  To handle this, I have crreated a component 'wrapper' that's an HBox with a NumericStepper inside her, and I can specify my attributes on the tag NumericStepper.

  (2) now that I did #1 above, although, when I click a DataGrid cell that uses this component editing, the editor comes back but the text box is NOT centered, which means that the user must click a second time if he wants to type a number.  It's very irritating, but I do not know how to manage the focus such as when my HBox-with-embedded-NumericStepper' control rises, it concentrates and its selected data, NumericStepper, just as the 'base' is.

  So, my questions are:

  (1) can I somehow assign property values to a standard when executing NumericStepper, so that I can avoid using my built-in custom control HBox?

  (2) how can I manage the focus so that when my control HBox is in place, the text box is selected and fucused?

  That sounds confusing, but I have a small program to demonstrate this.  The "QtyBad" column uses my own NumericStepper HBos-based and not to be put in the correct focus when activated.  The "QtyGood" column has demonstrated APPROPRIATE behavior, as exposed by the native NumericStepper component, but I can't specify additional attributes / s on this subject.

  Here are all of the program - called "DGNumStepperDemo" - here:

  DGNumStepperDemo.mxml

  <? XML version = "1.0" encoding = "utf-8"? >
  " < = xmlns:mx mx:Application ' http://www.Adobe.com/2006/MXML "layout ="absolute"creationComplete =" onInitialize () "> "
  < mx:Script source = "DGNumStepperDemo.as" / >
  < mx:DataGrid id = "dg1" editable = "true" top = "20" left = "20" width = "350" height = "124" >
  < / mx:DataGrid >
  < / mx:Application >

  DGNumStepperDemo.as

  
  

  ActionScript file
  Import mx.collections.ArrayCollection;
  Import mx.controls.DataGrid;
  Import mx.controls.dataGridClasses.DataGridColumn;
  //---------------------------------------------------------------------------------------- -------
  [bindable]
  private var gridData:ArrayCollection = new ArrayCollection([{Qty:0},{Qty:5},{Qty:10}]);

  private function onInitialize (): void
  {
  CDL of the var: Array = new Array();
  var dgc:DataGridColumn;

  DGC = new DataGridColumn ("QtyBad");
  dgc.dataField = "Qty";
  DGC. Width = 75;
  dgc.itemEditor = new ClassFactory (EditorDGNumericStepper);
  dgc.editorDataField = "value";
  cols.push (DGC);
  
  DGC = new DataGridColumn ("QtyGood");
  dgc.dataField = "Qty";
  DGC. Width = 75;
  dgc.itemEditor = new ClassFactory (mx.controls.NumericStepper);
  dgc.editorDataField = "value";
  cols.push (DGC);

  DG1. Columns = cols;
  DG1. DataProvider = gridData;
  }

  EditorDGNumericStepper.mxml

  <? XML version = "1.0" encoding = "utf-8"? >
  " < = xmlns:mx mx:HBox ' http://www.Adobe.com/2006/MXML ""4"verticalAlign ="middle"paddingRight ="4"paddingLeft = verticalScrollPolicy ="off"horizontalScrollPolicy ="off"> "
  < mx:Script >
  <! [CDATA]
  public function get value(): number {return itemQuantity.value ;}
  []] >
  < / mx:Script >
  < mx:NumericStepper id = "itemQuantity" value = "{data.". Qty}"minimum maximum ="0"="100"/ >
  < / mx:HBox >

  If anyone who bothers to run it, you can see what I mean about the focus problem in the QtyGood and QtyBad columns.

  Any help is appreciated!

  Quick response to the #2 is to change the EditorDGNumericStepper.mxml to the following:

  
  http://www.adobe.com/2006/mxml"
             verticalAlign="middle" paddingRight="4" paddingLeft="4"
             verticalScrollPolicy="off" horizontalScrollPolicy="off"
             creationComplete="focusManager.setFocus(itemQuantity)">
       
            
       
       
  
  

  The only thing I did was put the NumericStepper to 100% width so it fills the column like the standard NumericStepper and it looks a bit better and I added a creation complete event handler that sets the focus to the NumericStepper.  I tested it and it will be emphasis each time on it like a standard stepper.  There may be a more "preferred" way, but it's simple and effective.

  On the #1 question, you want to change the properties, styles, etc. of a NumericStepper standard once it has been added to the data grid?

• set the focus to the text fields named incrementally

  I created the many (hundreds) of the fields of text through actionscript. I gradually name them and place them on the stage and then subsequently access to set focus.
  I use create a textfield object:
  var txtbox:TextField = new TextField();
  
  and then use a name incremented to the text field to identify it later:
  
  var txtname:String = txtn + txtcnt; txtcnt is a number incremented variable. txtn is a string variable.
  txtBox. Name = txtname;
  
  I add an eventlistener on stage. The event listener works very well and has a companion function.
  I can identify the text field I want access once the move is running through his name.
  Then I use this .name property to set the focus:
  
  internship. Focus = "txt88";
  
  Again, "txt88" is the .name of the text field.
  
  What I am doing wrong?
  
  ypeError: Error #1034: Type coercion failed: cannot convert "txt88" in flash.display.InteractiveObject.
  to MethodInfo-(200)
  
  
  Also, I tried to use the variable incremented during this step, but get a msg of error affecting the variable this way textfield name.
  var txtname:TextField = new TextField();
  

  Awesome!
  Who did it! I appreciate your help. It is a major obstacle and I went through the help files and books without success. (If it works fine in the AS2 version!)
  Anyway, you are a lifesaver. Thank you.
