Flex :: Disable Carriage Returns Within An Editable TextArea?
Aug 2, 2011
I am simply wanting to stop a user entering carriage returns in a TextArea. I have been experimenting with the 'restrict' property in the TextArea but cant seem to work it out.I have the following code:
<mx:Canvas id="cvs1" label="Panel 1" width="100%" height="100%" creationComplete"addEvtListnerOnPlaceText()" backgroundColor="#FFFFFF">
<mx:TextArea id="txtP1T1" x="10" y="176" text="{placeName}" width="210" textAlign="center" color="#DC0000" restrict="this is where I need some help"/>
</mx:Canvas>
I've now managed to get something working:
private function addEvtListnerOnPlaceText():void{
txtP1T1.addEventListener(KeyboardEvent.KEY_DOWN, onKeyEventDown);
txtP1T1.addEventListener(KeyboardEvent.KEY_UP, onKeyEventUp);
[code]....
The only issue now is that if you hold return down, it clears the first carriage return and then keeps adding as long as you hold it down. I need a way to stop this happening without just losing focus on the text area.

I have a TextArea component in a flash document, and this TextArea is loading text from a .txt file.
However, when you're viewing the textarea in a webpage, you can not only select the text that has been loaded into the textarea, but you can also delete the text written there, like it's a word document or something.
Is there any way I can disable this?

My XML looks like this...
<feature title="This is my /n features title"/>
I don't have access to change the schema.
In Flash I load the text content of the title attribute into a text field, problem is -- the prints instead of operating as a carriage return (new line).
Again, no access to the XML so changing the TextField to htmlText and adding a <br/> tag wont work.

why i cannot get the carriage returns and tabs stripped from my XML. I guess the only drawback at this point is that i cannot form my xml file nicely and am stuck placing all my node text on one line.
So far here is what i have tried without any luck;
ActionScript Code:
var subXml:XML = new XML();
subXml.ignoreWhitespace = true;
subXml = new XML(e.target.data);
[Code].....
I am otherwise at a loss as to why it's leaving the tabs returns etc. in my textFields when i populate them with the node data.

I've got an app where I'm grabbing the currently highlighted text from the user in a RichEditableText block and I've noticed that when the user highlights a selection after a carriage return that selectionActivePosition and selectionAnchorPosition return values that don't count the carriage return, even though when I slice the corresponding text with the retrieved values, it does take the carriage return into account and therefore returns a value shifted one character to the left for each carriage return appearing earlier in the text.

How do you scroll an editable TextArea (Flex Hero) on a touch device? I am referring to the situation where the text does not fit in the TextArea height.When I try to tap and drag the text gets selected and not scrolled... Am I missing a something here? I am using verticalScrollPolicy = on (also tried auto).I am testing the code in the Blackberry Playbook simulator (my targeted device for my app).

it's possible to restrict hard returns in text input fields? I've tried something like this:my_txt.restrict="^u0013", and a bunch of variations thereof, but nothing seems to keep the Enter key from doing it's thing. Second best would be to traverse through a string a user has entered and replace hard returns with a space or dash, but again I've had no luck looking for or . I've tried entering text and hard returns into a dynamic textfield set to input, but when I try this:
var n:Number = my_txt.indexOf("
")...
trace("n: "+n) //traces "n: -1"

I have an editable datagrid. If sorting is applied by clicking any header of datagrid, it works fine. But after that, if data values are changed in any row of datagrid, sorting is applied automatically. How to prevent from this behaviour? i.e. sorting should only be applied if user clicks on any header of datagrid and sorting should not be applied when user modifies data in grid.

I'm having issues with the property "editable" of textArea control. I have a component: OrderView.mxml and it's associated data class OrderViewData.as. Orderview.mxml is inside a viewStack to enable navigation from a component to another. In this particular case, OrderView.mxml is called by another component: SearchResult.mxml. I can thus navigate from SearchResult.mxml to OrderView.mxml, and back to SearchResult.mxml... OrderView.mxml has textArea and textInput control, that have to be editable or nonEditable depending on the property var isEditable:Boolean from OrderViewData.as.
When the application is launched, isEditable = true. So, all textInput and textArea controls are editable the first time the user gets to OrderView.mxml. When the user clicks on the button order from OrderView.mxml, isEditable = false. When the user goes back to SearchResult.mxml, isEditable = true (again) --> Until here, everything works fine. The thing is: when the user goes back to OrderView.mxml for the second time (and beyond), even if the property isEditable = true, textArea controls are still non editable... But the textInput controls are editable!

I'm pretty familiar with Actionscript, and this one has me completely stumped.

I have a load file and a write to file method. We all know what they do. How ever load always returns true and write always returns false....Right there you know somethings wrong. Because The forums have an issue with me posting code...I posted it here: [URL] Based on this code what is the issue here? why is write always returning false and why is load always returning true? (even for files that do not exist). My understanding is that if flash cannot find the file it should write to it will create it and if it cant load said file, then that method should return false.

Users need to be able to paste the contents of an Excel spreadsheet into a grid in my flex application. I have implemented this using a TextArea with a change event handler that parses the text the the user pastes - splitting it up by newlines and tabs - and adding it to the ArrayCollection that is bound to the grid. However, it makes no sense for users to be able to manually enter text into the TextArea. How can I prevent them from doing so?

I realize that ItemFocusIn is somehow only applicable to editable datagrids in flex,nevertheless I want to fire an event anytime the user selects a new row in a non-editable datagrid. I have successfully used the CLICK event, but this event is not fired when the user uses the keyboard to select a different row in the datagrid. What do I have to do to cause an event to fire whenever the currently highlighted row in the datagrid changes, regardless of weather it was changed by the mouse or by the keyboard?

All i have a flex editable datagrid. By default if i press the left navigation arrow key , it moves to the left but not to the next cell. I would like to override the keydown event such that if the left navigation arrow key is pressed down i set the focus to the next cell on the left.
In short the user needs to be able to navigate using the keyboard through the cells using just like in excel(currently the arrow keys move between characters within a cell).

I'm trying to override the default handling of the 'up' and 'down' keys for an editable list, such that when they are pressed a list entry that is being edited behaves as if the escape key has been pressed, but the 'selected item bar' moves up or down.
Here is my (simplified) component:
<?xml version="1.0" encoding="utf-8"?>
<mx:List xmlns:mx="[URL]"
enabled="true" width="100%" height="100%"
creationComplete="initialise()"
editable="true"
[Code] .....
For some reason this doesn't work: if a row is being edited, the first 'up' (or down) keypress ends the edit and moves the bar. Further up or down keypresses have no effect, but if you click somewhere near the list it does start working. This makes me think it is a focus issue. Weirdly, if you hit escape the edit finishes and you can move up and down correctly. If the 'callLater' line is uncommented to try and make the list retain focus, the bar initially moves in the direction of the keypress but then moves back again and re-edits the original line!

I'm using a Flex datagrid where only 1 rowItem is editable. All the other row items are non editable. When I edit the value of the row, and press ENTER or TAB the focus is send to the next editable item in the datagrid. In this case the editable field on the next datagrid row.
I don't want this standard behaviour... I don't want the focus to be processed to the next editable item. Since the data is saved instant, it's quite strange that the focus is given to the next field. The focus has to be remained on the item that was edited.

I have an advanced datagrid, but I want users to allow to copy some lines they want. when I use the property editable they are allowed to select the text they need, but they also are allowed to edit this. How can I prevent that?
I want users to be able to select any text in the datagrid, but they are not allowed to change the value of the grid. They should only be allowed to select and copy (ctrl + c).

I'm having with a menu navigation system. I'm using Flash MX. I have created a menu system for the site I'm building ([URL]) where one of the buttons "Choose photographer" drops down a list of names. All the other buttons just jump to another page. The drop down is currently using tweens also the logo moves to the left as the dropdown appears and returns when the dropdown returns. All working fine apart from its a bit jerky.
It's I just wanted to get away from tweening and use action scripts instead, as I'm a newbie to all things Flash I trawled the net for tutorials and examples so that I could cobble together the exact same effect. I have managed to get the drop down work and return using the action script and it does seem smoother and works slightly better. But can I get the logo to move to the left and back in time with the drop down...no.

Within my AS3 class I am calling this.width, and the value it returns is always 1, even though this is impossible given the contents of the object.
Is this a standard behavior for AS3?
Simple version of class is posted below. It is attached to a MovieClip symbol that just contains a simple hexagon.
package {
import flash.display.*;
import flash.utils.*;
import flash.events.*;
public class Hexagon extends MovieClip
{
var startWidth:Number;
var startHeight:Number;
public function Hexagon()
{
var myTimer:Timer = new Timer(2000);
myTimer.addEventListener(TimerEvent.TIMER, timerFunction);
myTimer.start();
startWidth = this.width;
startHeight = this.height;
trace("startWidth:" + " " + startWidth);
trace("startHeight:" + " " + startHeight);
}
function timerFunction (evt:TimerEvent):void
{
}
}

I have an ArrayCollection with following structure (when viewed in debug mode):
[0]
- [0]
-- src
- [1]
-- src
src is the path to an image.
I need to get all of the src's out of the arraycollection. However because of the first (unnamed) node I can't take them in. I've tried ArrayCollection[0].children and save the result in another ArrayCollection, however the new ArrayCollection has 2 Objects in it but no 'src'. There are just 2 null objects
firstArrayCollection is filled with the data as described above.
secondArrayCollection.addItem(firstArrayCollection[0].children);
When viewing the content of secondArrayCollection i see following structure (and data):
[0] null
[1] null

I am trying to get the value of a global variable from JS. The variable is defined in the HEAD section of my HTML document.
if(ExternalInterface.available){
return ExternalInterface.call("window.myVar.toString()");
}
As I debug my application this call keeps returning "undefined" but if I make the same call in firebug's console it returns a string as expected.

I have an app where I am looking to make the enter key act like a tab key. I can easily capture the keypress event and setFocus to a textinput field. The problem is figuring out which textinput field to give focus to. I have this code
trace(this.window.focusManager);
//returns TheWindow86.focusManager
trace(this.window.focusManager.getNextFocusManagerComponent());
//returns null
//This is what I was hoping would work
this.window.focusManager.getNextFocusManagerComponent().setFocus();
The code is in a controller class and "this.window" references an instance of a nativeWindow mxml file "TheWindow.mxml". The first trace works as expected, but the second one gives null.

I'm parsing an AdvancedDataGrid, and the dataField for one of the columns is a Boolean value. The column also has an itemRenderer (that I cannot change or modify). itemToLabel seems to work on every other column except for the one in question (the boolean). Ideally I would get a '0' or '1' or 'true' or 'false' string returned. Is this possible?
