How can the text in a Label control (or a similar control) be wrapped in Flex 4 beta? In Flex 3 I could use the Text control but this is no longer available in Flex 4.

I have implemented this one. I am getting 5 textboxes with empty value, if I entered some value in each textbox then, I want to get specific 3rd textbox value wen some event trigger.
I've spend hours searching for a way to put one paragraph of text in one tree node in Adobe flex. How can I do it? I created a simple tree view but the text is cut after the right border.
So I tried to create a tree renderer. In the renderer I specified width=100 and the text wrapped. But the height of the nodes was not being calculated properly, so the text over consecutive nodes overlapped and got messed.
So how do i do wrapped text in a tree node?
In AS3 do you have a label or a control to simply display text.Not a textbox type where you can enter text.
View 4 RepliesI have a flex project where I uses the spark RichText control quite extensively, there are places where it is possible for me to replace RichText with the Label control - (The rich text occurred due an import from Flash Catalyst). My question is, is there any space/performance advantage in using Label over RichText, since Label seems like a much lighter option, I am building a web app, size matters.
View 3 RepliesI just would like to know how can I dynamically change a label's values while on mousedown.I basically have a mousedown event and I also have two labels in my application. What I would like to happen is to get the current x and y position of my mouse pointer as I move my mouse through the screen and changing the values of the labels into the values of the current x and y coordinates of the mouse pointer.
protected function object_mouseDownHandler(event:MouseEvent):void
{
curX = this.mouseX;[code]........
However, what this code does is that it records the coordinates of my mouse as it moves across the screen. What i want now to do is just to get the coordinates of the mouse while event is on mouseDown. What i'm thinking is to call the mouseDown event and ask it if the mouse is currently down, if it returns true, then i'll start recording.
I have wrapped text in a box I'd like to do a "zoom-in" effect on. It is 3 lines long in the box. I don't want to make the font size bigger and bigger because that will change the way it wraps. Do I have to "break apart" the layer until it's outlined? I'd rather leave the text editable.
View 3 RepliesI want to add scripting functionality to my Adobe Flex application. I know it's possible to use the Browser control, and add the script packaged as a HTML file to the Browser control, and expose Flex objects. However I'd like to if it is possible to execute JavaScript without using the Browser control.UPDATE: I guess my question hasn't been clear enough. I'll explain what I'm trying to do.I want to make my application customizable using JavaScript ie., add scripting/plugins to my application dynamically.I realize that it's possible to dynamically execute Javascript by inserting the JS code into the HTMLLoader control. I would like to know there is a direct way to execute JavaScript without inserting it into the HTMLLoader control.
View 2 RepliesI'm running into an issue where, if the dynamic text field I create wraps and autoSizes to 2 lines or more, the last disappears (sometimes partially). However, this only happens when I apply a DropShadowFilter to it. If I don't apply the drop shadow filter, it renders correctly. Note that whether or not the text renders correctly, flash seems to know that the text has wrapped and autosized, as this is how i assign the Y position of the second text field below it. See code below:

I created a list control at runtime as following:
[Code]....
//Where myDataArray is an ArrayCollection consisting of my Custom ValueObjects. When i execute the code it displays my list with custom item renderer, which is fine. But when bring my mouse over it, it doesn't give any colour highlight which means it is not selecting. Secondly, when i click on any of the list item, it doesn't dispatch any change event. I tried a lot but couldn't understand it.
I have created Columnchart in Adobe Flash Builder.
Now I want to control that column chart with Slider. I want to change the column chart according to value of the slider.
how it is possible to create an input box for the user to type their text and make the text appear wrap around a circle dynamically and the radius of the circle can also be changed dynamically?
View 1 RepliesI'm trying to use XML to convert the code that a Flex RTE creates to valid HTML. No problems on other HTML elements, but difficulty with unordered lists. I created a solution for moving consecutive LIs into a UL node. After trial and error, I came up with the following solution. My question is - surely there's a better way to do this?
for each (listXML:XML in xml..li) {
if (listXML.children().length() == 0) {
// list item is empty - make it an empty paragraph instead

I have Class1 with a read-only bindable property called age:
public class Class1 {
private var _age:int;
[Bindable(event="ageChanged"]
[Code]....
Of course the [Bindable] tag there doesn't make sense. But how can I achieve the same effect?
I believe I can dispatch some sort of ageChanged event from Class2 up to Class1 and then have an event handler in Class1 dispatch another local ageChanged event to which I bind Class2's age property.
Flex's text-editing controls (mx:TextField, mx:TextArea) offer functions for doing "stuff" with the selected text (selectionBeginIndex, selectionEndIndex, setSelection), but the text-displaying controls (mx:Label, mx:Text) don't seem to offer anything of the sort.After some tinkering, I've tried subclassing Label then writing functions which give access to the underlying TextField instance... But even then, setting the selection didn't work![code]So, is there any better way to access/change the text which is selected in mx:Label and mx:Text controls? Are there "better" controls to use?

View 1 Replieshow do you change the text inside of a text control when a user has clicked a button. I could not find a way to do this. I used an event handler to input a .xml to a string and then to the text control. This doesn't seem to work.
View 1 RepliesI have a component where a Button is wrapped in BorderContainer. I'm passing a custom property to the component at run-time to change the label of the button but Flex is reporting the following error:
Cannot access a property or method of a null object reference
When the error occurs, Flex highlights the following code:
myButton.label = value;
Here's the app:
// MyApp.mxml
<?xml version="1.0" encoding="utf-8"?>

i am trying to make a simple form but when i place a textInput box after a Label it comes in the next line..how do i make the text input box be placed besides the Label?
View 2 RepliesI need to make a small app accessible to screen reader.I'm managing to make buttons accessible, but I would also like to have a section of text accessible by screen readers so that users can hear what the text says.
I can't seem to work out how to do this.. I've tried various text controls and set them as focusEnabled, tabEnabled, i've set the accessibility* attributes too but it never seems to work, I cannot tab to a text label and hear the content.
I'm honestly a little new to accessiblity in Flex so apologies if i'm missing something obvious.
I got very basic question. Why this is not working?!

I am trying to add an item to a list and have text display and have a different hidden value when i access selected items. I also need to do this with a loop.
Currently i am trying to add a label and set the labels id to my value. But the list just shows the ID and not the text.
var theLabel:Label = new Label();
theLabel.id = "123";
theLabel.text = "test";
lstLayerList_array.addItem(theLabel);

If I create a mx:Label or mx:Text control in Flex and then set an opaqueBackground to it, I notice that there is some space around the text.
I would like to be able to get rid of that space to where the text is completely flush to the top and bottom of the label. Changing the gap, padding, and leading didn't seem to help. Is it possible to get the text completely flush to the sides of a label?
Is there a way, for a Button's "label" field, to display text over several lines? Or else to automatically "wrap" the text in several lines instead of cutting part of it?

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?
i have created a group in run time and then added in it two buttons and one label
addElement (myGroup )
myGroup.addElement ( button 1 )
myGroup.addElement ( label )
myGroup.addElement ( button 2 )

How can i change the text of label using this event.currentTarget. How can i target the label
I'm a new to Flex, and I'm trying to add a second label to a text box.
like this: Label [_______] label 2
So the first label will describe the text box and the second the unit, for example:
cost of cleaning [_______] $ per hour
Can I do this with a label inside the form item?
what I have tried looks like this:
mx:FormItem label="cost of cleaning">
<mx:TextInput id="proSRO2YO" text="" width="120" maxChars="20"/>
<mx:Label text="dollars per hour"/>
</mx:FormItem>
but that results in a second label one line below, I need these on the same line.
I am using spark.label for Mobiles in Flex, I want gradient on label text instead of solid color. But performance should be kept in mind as it will run on mobile device.
