ActionScript 3.0 :: Setting Y Property Of Textfield?
Apr 16, 2010
I was trying to create these 17 textfields in a for loop. I ended up instanciating them manually and now I am trying to set some of their properties in a for loop. The problem is that when I trace them I just see [object textfield] but not the names. If I try to trace the ".name" I get instance 1, instance 2, etc. The real problem is when I try to set the "y" property I get an error "1010 A term is undefined and has no properties"
Code:
var tf1:TextField = new TextField();
var tf2:TextField = new TextField();
var tf3:TextField = new TextField();
[code]....

Short version:Setting a TextField's 'text' property seems to be quite slow. Any way to optimize this?Long version:For a video player I'm working on, I've rewriting a bunch of code I've written in the past and optimizing where I can, and I've noticed something a bit strange.I have a time readout (the typical "00:00 / 01:00" thing) that I'm updating every frame, and it seems to be gobbling up FPS (I'm using mrdoob's great little Stats class for monitoring).The thread to make the call is a bit heavy -- involving a dispatched custom event from the FLVPlayer class (with the current netStream.time as a property) onEnterFrame, which is passed up 2 parents and then back down via a function call -- but I've isolated each step along the way and everything is totally fine (running at or close to 30fps) right up until that very last call where I set the TextField.text property, which results in about a 10fps drop.
If I comment out the setting of TextField.text it runs great, but even if I set it to something arbitrary (like currentTime.text = "0") -- bypassing the reformatting math -- it just tanks.Anyway, anyone know if there's something I can do about this? I've considered using a Timer set to 100m instead of onEnterFrame, but I actually assumed the overhead would come from the dispatching of and listening to the event as well as the reformatting of the time, but *not* the very last step of setting the .text property, which is something I can't avoid whether I use a Timer or onEnterFrame.

i'm creating a completely dynamic form. i want to assign a variable name to a textfield and then pass that variable with a LoadVars() object.
here's a small piece of code i can't get working:
//create movieclip (used like a form)
_root.createEmptyMovieClip( 'dialog_body', 0 );
//create textfield input
[Code].....
bottomline: if i create a textfield using the traditional method and assign the 'var' it works fine. if i create a textfield dynamically at run time, and use the *.variable property, the variable is NOT sent..

I'm using createTextField to create a textfield. I have also created a input textfield with a variable called textline1 (I don't create the inputfield with as).I want to display the letters in the created textfiled that I'm typing in the input field. So this in my AS coed:
_root.createTextField("text1",1,100,100,300,100);
text1.variable = textline1;
format1 = new TextFormat();

I am trying to figure out why some letters (like the norwegian Å (Å)) are cutted out in the middle of the top "o":
My code is this:
var titleFormat:TextFormat = new TextFormat();
titleFormat.size = textSize;
// this is embedded font, and exported for action script, declared
titleFormat.font = myFontBold.fontName;
titleFormat.bold = true;
[Code] .....
So, I have tried different things like setting height hardcoded and bigger than text, but top us cutted again, I have tried with css but no success. Why the letter is not showed fully and why if I zoom in the swf (2-3 zoom ins) it shows up normal (and what i try to achieve) like this: I think it has to do with the topMargin, but unfortunately I didn't find something like that in as3 documentation.

This marks a new chapter for me asking a question about an entirely different subject that I know nothing about I'm following a book called "Flash Games" and it's not for beginners and I'm a beginner so lots of jargon that I don't know and simple google searches don't come up with anything. What is the Flash IDE? Does this author mean the application Adobe Flash to build applications. So that means there is Flex, and Flash Catalyst, and Air IDEs? I don't really treat this like IDEs in terms of programmer but I guess I just don't know. The author says to set the document property on my file.fla to Game. How to do this?

maincanvas.addChild(textarea);
flex throws the error :

ive got a radiobutton component on my stage named radio1. I need to duplicate it and then change a few properties, but i cant seem to get the path/naming right. This is my code:
Code:
i=2;
radio1.duplicateMovieClip("radio"+i, radio1.getNextHighestDepth(), {_x:20, _y:20});
_root["radio"+i].setLabel("test");
i++
if i use a constant name instead of "radio"+i it works but the ["radio"+i] seems to be the problem, could someone help me with this? (using flash mx)

I'm trying to convert an MXML component to an ActionScript Class. The component consists of a Form with a TextInput, TextArea, and two buttons - Save and Cancel, and a Validator for the TextInput, and other logic to handle events that occur. This component is currently extended by several other components. Now, in the MXML component binding the TextInput text property to a property in an Object was very easy:
<mx:TextInput text="{_itemToEdit.name}" />
But in ActionScript, I'm creating the TextInput and setting the text property before the Object is set, and the TextInput is not being updated:
public var itemToEdit:Object = {};
private var nameInput:TextInput = new TextInput();
public function MyClass() {
nameInput.text = itemToEdit.name;
}
How can I make sure that the TextInput text property is bound to the specified property in the Object?

I'm looping through a recordset, and for each item I create at runtime a spark Label and set the text property from a field of the recordset. The labels must have a fixed width and some text goes multiline. I want to arrange the label vertically so I need to know the height of the label so I can place the next label properly, but when I try to read this property, after the labels is added through the addElement mehtod, it returns 0.
how to get the label height?

Folx; Does the manual document the setting of transparency in TextField.textColor or TextField.backgroundColor, not just the _alpha of the TextField altogether? If so, I cant seem to find it. In addition to the RGB/hex values, the color palette in the Properties panel allows you to set transparency in %, yes, but can this also be achieved programmatically?

I am using the combocheck example from the following site: [URL]
It's a very useful component and works very well.
Now, I need to set the text property of this combo box upon application startup with certain values (which are defined dynamically according to some criteria). The problem is that although I have no problem setting the text property of the combo box at other times of the application run, setting the property at startup seems to have no effect unfortunately.
For example, I want to set the text property of the combobox to "Bob" (which is one of the items in the dataprovider for the combobox) and the "set text" method is called on the combo box. Performing a step-through shows that the "set text" method is receiving the correct value item but not setting the _text property.
I have tried not doing anything until "ApplicationComplete" but no joy there either.
Here is the code (a combination of the code from the URL above and some other changes to it). However, as I've stated above, the codes does work. The problem is that it doesn't work at the application startup. Whenever an event is fired and setComboText is called as a result, the text of the combo box is set correctly.
private function onComboChecked(event:ComboCheckEvent):void {
var obj:Object=event.obj;
var index:int=selectedItems.getItemIndex(obj);

Long time listener, first time caller here. I'm having trouble with how Flash sets the _x property of a dynamically created movieclip. If I create a rectangle on the stage using the Drawing API:
Code:
//for the purposes of this example, assign a value to i
var i:Number = 0;
//assign var squareName
var squareName:String = "square" + i;
//create an empty movieclip named [squareName] at depth 1
this.createEmptyMovieClip([squareName], 1);
[Code] .....
I'm not new to Flash by any stretch of the imagination, but I have never come up against this problem before. For context, I'm actually getting my feet wet with the Tween class, and am having trouble animating dynamically created movieclips due to this confusion with coordinates. When I tween a dynamically created clip from one set of coordinates to another, they are offset by the movieclip's _x and _y properties starting at 0, 0, rather than their actual position on stage.

I have a MovieClip that has a Dynamic TextField: let's call the instance of the field txtName. I want to set the text field on the fly for txtName, so I add a little ActionScript (3!) that does it nice and easily: txtName.text = "Foo";reat. Now why isn't it working when I try the same thing from a parent MovieClip which contains the MovieClip that has the dynamic text? Example:Child MovieClip with TextField ActionScript 3 in Frame #1:
//------
function SetText(str:String):void {
txtName.text = str;

i have a textField wherein i uses embedded fonts, the problem is when i change its size and i do not set the SAME scaleX and scaleY value, it seems to compress the letters inside it when i make it smaller, and stretch the text when i make it bigger... i tried using width and height values (instead of scaleX and scaleY but its the same result)... it seems that the embedded fonts are maintaining some kind of aspect ratio or whatever, and again this only happens when embedFonts is set to true

Adding properties to MovieClip is super easy.
I use myMc.index a lot of times. It is very handy for connecting MovieClips to other MovieClip via a dictionary.
Now I wanted to add an EventListener to a TextField. No problem. But how do I connect that TextField to another MovieClip?
myTextField.index doesn't seem to work.

I am populating a textfield programmatically and scrolling to the maxScrollH as the new text is added so the user can see the progression of text. This works fine, until I click the TextField, which sets scrollH back to 0 and places the caret in the text at the equivalent position.
textField.setSelection( text.length, text.length );
//sets the caretIndex/selection to the end
textField.scrollH = textField.maxScrollH;
//scrolls to max
This is the code that I am using to scroll when the textField text property is updated. I've tried adding a listener to the click event on the textField, which works in a way, but causes a visible jump.
override protected function createChildren() : void {
super.createChildren();
textField.addEventListener(MouseEvent.CLICK, handleTextFieldClick, false, 0, true);
} protected function handleTextFieldClick(event:MouseEvent):void {
textField.scrollH = currentTextFieldScrollPosition; //stored scrollH value
trace(textField.scrollH);
}
My guess is that there is a scroll position being calculated or stored someplace that I can't find.
