ActionScript 3.0 :: Focus On Textfield In A Child Movieclip?

Aug 26, 2010

I have a problem with setting focus on a textfield in a child movieclip from my DocumentClass.

I have a function in my DocumentClass that try to set focus on a textfield in a child movieclip:

private function setFocusOnUserName():void
{
this._mc._txUser.stage.focus = this._mc._txUser;
}

But I get that stage is null.

And I get error message:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at com.ro.main::DocumentClass/setFocusOnUserName()
at com.ro.main::DocumentClass()

ActionScript 3.0 :: Set The Focus Back To The Textfield And Put The Caret At The End Of The Textfield?

Jul 24, 2011

I have a numerical stepper,and a user can click on a textfield, then click the up and down arrows on the stepper to change the font size,i then try and set the focus back to the textfield and put the caret at the end of the textfield, but the stepper keeps focus anyway.Here is the event handler for when the stepper value is changed.Get the textfield's current format, change the size, set the new format, then focus on the textfield and set the caret position, but the caret just stays inside the stepper.

Code:
private function handleChangeTextSize(e:Event):void
{
var tField:TextField = Main.LAST_FOCUSED_OBJECT;[code]....

I've had problems with other components too with the exact same focus issue and the only solution i've ever come up with is to set a timeout for like 100 milliseconds to set the focus back then and it works. another way to do this without the "hack"?

ActionScript 3.0 :: Moving Focus Away From A TextField?

Nov 5, 2009

i have made a flash movie which is working perfectly. I used the tutorial by GotoAndLearn which you can find here...[URL]... which shows how to make a preloader as a separate swf file and he states that you won't need to worry about the swf file that is loaded by the preloader.

He was correct for everything in my movie except for the

Code:stage.focus = null; code which i use to move the focus away from a textfield once a person has entered text and hit the Enter key. Basically, i just don't want the typing cursor to hang around after the user hits enter.

ActionScript 3.0 :: How To Send Focus To TextField

Jun 7, 2011

I had a question regarding the 'passing' of focus. I have a class (more like a component) which contains a TextField.If I give 'focus' to the class, how can I send the focus to the TextField (which is private to the class containing it, like a component).To elaborate, I'm not sure focus occurs on 'just the endpoint' or 'to a branch'.If focus is just given to the endpoint, how does my component disregard having focus and gives the focus to the endpoint?If focus is a given to a branch, what if focus is given (via mouse click) to the text field? I would have an event listener catch the focus event which shares the focus with the parent, but the problem there is once the parent has focus it shares the focus with the child which creates a loop.

ActionScript 3.0 :: Textfield Focus With Flashing Bar

Jan 9, 2008

I'm trying to make Flash automatically focus on an input textfield (not the TextInput component object, but a textfield object with type set to input) when the user enters the page. I want it so they can type straight away without actually having to click inside the textfield. Previously in AS 2.0 you could use Selection.setFocus("textfield_txt"); but in AS3 is it possible?

ActionScript 3.0 :: Focus To A Textfield On The Stage?

Aug 21, 2010

I am new to AS3 and trying to figure out how to set a focus to a textfield on the stage. I found out that if I use stage.focus = tf; then the tf get the focus and it does, when I type letters they go directly to this textfield.Problems are, I don't have a blinking cursor in the textfield. I added event listener to catch up when the user press the  ENTER  key but it catches the ENTER key ONLY after I click the textfield with the mouse and having a blinking cursor in that textfield.

Flex :: Set Focus And Selection On A TextField?

Jan 16, 2011

I am trying to programmatically pass focus to a newly created TextField, but for some reason setSelection and setFocus do not work. For example, see my test code below:

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" creationComplete="_init()">
<mx:Button click="{tf.setSelection(1,2)}" />[code]....

The only setSelection that does anything is the 0,3 one on MOUSE_DOWN. I assume this all has something to do with the text field receiving focus with the mouse click,

ActionScript 2.0 :: Focus Set - No Flashing Bar In TextField?

Feb 2, 2010

In as2, I have a button that attaches a movieclip with inside some input text fields (a mail form). Now, as the tweening ends for the movieclip to actually appear (I set the _alpha to 0 as he's been created and change the value to 100 with a tween), I call a function for setting the focus on the first input text field:

Code:
function setTheFocus(){
Selection.setFocus(_root.mailtext.namex);
trace(Selection.getFocus())
}

Where 'namex' is the istance name of the input text field. The getFocus trace returns positive, so the focus is there but ... there is no flashing bar within the field. If I write something, the text appears in the right text field and the flashing bar appears. I can't get why there is no flashing bar without typing anything, even if the focus is set.

Actionscript 3 :: Set The Focus Of A Input-TextField Without Having A Stagereference?

I got a text-InputField:

textfield.text = "";
textfield.type = TextFieldType.INPUT;
addChild(textfield);

because this textfield don't reside in the main-class, I don't have a stage-reference for doing:

textfield.stage.focus = textfield;
or
stage.focus = textfield

How can I force the textfield to display the blinking line at position zero?

Actionscript 2.0 :: Override TextField Focus Event?

Jan 17, 2011

Is it possible to override the default focus event on the in-built TextField class? So for example when a textfield gains focus a custom event is triggered rather than the default one? I know we can use the onSetFocus event, however we have over 1200 swfs that use TextFields so want to do it on a global scope rather than having to modify each individual swf. that on an Android tablet selecting a TextField brings up the android keyboard that not only shrinks the flash content, but defaults to the alpha keyboard when all we want is numeric (it's a Maths app).

ActionScript 3.0 :: Keeping Focus On Textfield Type Input

Feb 24, 2009

On my stage I have an MC with a textfield of type input. I have another MC on stage with the control for the input like bold, and italic. When my textfield has focus and I click on one of the control MC buttons it loses focus. I know I can reset focus with stage.focus but wanted to know if there is a better way. Like disable the control MC from taking the focus off the input text. I thought this was not the behavior. I thought that only another input type control can steal focus until now.

ActionScript 3.0 :: Stage.focus Doesn't Show Cursor In TextField?

Oct 5, 2008

stage.focus = txt; // txt is a text input field

It successfully gives the TextField "txt" focus because when I type, the characters appear in the input textfield, however the familiar blinking text cursor/beam does not appear in the textfield. This makes you think it does not have focus, so you click the textfield to give it focus -- completely defeating the purpose.

ActionScript 3.0 :: Input Textfield Focus - Get The Dredded Error 1009 When The Code Invokes TypeNames?

Jan 15, 2012

I'm developing a series of learning aids and the final screen requires the user to input some text.I have it working correctly but now need to make it a little more user friendly.At the moment the only way for the user to input the text is to click in each box. There are a total of 6 input text boxes.I would like to direct the user to a particular input text and then have them be able to use the tab key or the enter key or mouse clicks to proceed.As the first step I added the stage.focus = inputStarName1. See code below. As soon as I added the stage.focus = inputStarName1 line I get the dredded error 1009 when the code invokes TypeNames.What do I need to do to get rid of this error?
