Flex :: TextArea Scroll Down Doesn't Work
Sep 1, 2011
I have a TextArea that shows the conversation from selected chat room. For valueCommit event I use: verticalScrollPosition = maxVerticalScrollPosition; And it works fine scrolling text to the bottom. However in one case it doesn't work as expected. There's verylittle text, so TextArea has no scrollbar and then I put a lot of text and a scrollbar is necessary. The text is scrolled almost to the bottom (still a few lines need to be scrolled down). I am pretty sure it gets maxVerticalScrollPosition as if there was no scrollbar. So the question is how can I wait with updating verticalScrollPosition with respect to TextArea's new size (that is now with a scrollbar). I tried calling validateSize and other methods that start with 'validate' but unfortunately with no luck. I also tried the old trick of putting caret at the end of text. So the TextArea's scrollbar makes a difference when getting maxVerticalScrollPosition and I need to update verticalScrollPosition once all measurements are done. I forgot to mention. I use htmlText.

Consider the following mx:TextArea <mx:TextArea id="textArea"/>
periodically being updated with new lines of text using ..
textArea.text += newLineBeingAdded + "
";
how do I make sure the textarea is scrolled down to the bottom so that the last line added is visible to the user?

I have a TextArea that I don't ever want to be scrolled. When scrolling within the application that holds this TextArea, however, the scrolling stops as soon as the mouse ends up over the TextArea.
Is there any way to pass the scroll event to the application, or tell the TextArea to not claim the event?

I would like to disable copy event in the TextArea I'm using. To achieve so I added the following code block:
function initTA(){
var tf:IUITextField = body.mx_internal::getTextField();
tf.enabled = false;
}
<mx:TextArea id="body" creationComplete="initTA()" .../>
This is working fine unless the text area has lots of text inside in which case a scroll bar appears. After the scroll bar is being used by the user, the text area stopped blocking the copy event.
By the way, I am using text area for display purposes since I use rich text area format.

The old method for the mx:TextArea no longer works. Specifically:
myMxTextArea.verticalScrollPosition = myMxTextArea.maxVerticalScrollPosition;
I've found this method for Spark but seems a bit kludgy:
mySparkTA.scrollToRange(mySparkTA.text.length-1, mySparkTA.text.length);
Is there a more straightforward way to do this?

Trying to recode a scrolling thumbnail panel I found as an example of the web into AS3 mostly for educational purposes but getting stuck in a couple of places. The panel works but my problems are:
1) lower boundary doesn't work, panel continues to scroll into infinity.
2) as it is written, the mouse event that activates the scrolling is MOUSE_MOVE, which is kind of a pain as the scrolling is kind of "jerky", I have tried to make it an MOUSE_OVER event, but I think it may be conflicting with the prior MOUSE_OVER event.[code]

I just made a scroll area with buttons and draggable items. All the code is written for vertical scrolling, the content I need to be scrolled is going to be horizontal. how can I rewrite this code to be horizontal scrolling? it seems like the scroll button (the one you drag along) doesn't stay confined to its scroll line either.

I have a custom component that extends mx:TextArea,but when I try and apply backgroundAlpha= "0" it says The style 'backgroundAlpha' is only supported by type 'components.LabelEditor' with the theme(s) 'halo'.I don't see anywhere specifying that it is not using the Halo theme, unless it has decided to extend s:TextArea despite my not importing it.How can I make this component accept the style instructions or achieve a transparent background some other way?

In this code I'm creating a new window when I click the button. In the new window are TextInput and DropDownList components. When the new window opens, clicking the DropDownList does nothing - you have to click it a second time round to get it to open. However, click into the TextInput field first and then try opening the DropDownList works no problem.
Below is the code, or download the FXP file here.
// DropDownTest.mxml (application)
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"

When I run the resultant flash file on my remote server, it works 100% and test.text gets populated to "successful". However, when I run it on localhost test.text is still blank. If I check my network monitor in Flex, the httpservice was successful, so crossdomain.xml seems to be set right ...what am I doing wrong? I've been spinning my wheels for some time w/out a clue.

Why Flash Firebug doesn't work with flex 4.5?
UPDATE:
I have Flex 4.5 and in the main application, in the script tag I write:
import ominds.Firebug;
I use flash player WIN 10,1,85,3 Debug enabled. I export swf as 10.1.85 version.
And when I open the flashFirebug I get this: "No SWF files with the O-Minds package found, you should import the O-Minds package into your flash files. For more information visit: o-minds.com/products/flashfirebug"

recently I got a jagged image problem when scaling. I set my image components smoothBitmapContent true, and it works properly the first time, but if I reset the source, the images return jagged. It seems like the smoothBitmapContent property has been changed to false, but it doesn't work even if I set it to true in run time.Here's is my code:
<custom1:SmoothImage id="MJCard_3_36" x="286.5" y="56.65" scaleX="0.66" scaleY="0.83" smoothBitmapContent="true"/>
MJCard_3_36.source = seabedPicArr[index1-1][index2-1][index3-1];
I simply use a custom Image-extended class and switch smoothBitmapContent on, and I set the image's source in run time.

I have a CustomTextInput component based on TextInput (Spark) component. The instance of this class is placed on a popup window (TitleWindow). How can I capture the popup move (dragging the title) event inside CustomTextInput implementation?
MoveEvent.MOVE event of the CustomTextInput itself doesn't work. Of course, I can't access the parent popup window inside the component implementation, because it's a common component that can be used not only on the popup windows.

i'm creating a reusable flex tree component. And i would like to stick in the itemclick funtion. So that when a user clicks anywhere on one of the tree's Branches. the branch expands.My problem is that i don't know how i can get the listener function to fire.What i would like to do is create the tree completely in as3. (no mxml). Normaly i set the itemClick on tree in the mxml. but i want to do this in as3. My component has alot more functions in it but i have deleted them so that it becomes easier to read. I Thought if i override the createChilderen function and add the eventlistener in there, that i would work. But no luck.
this is my code;
package
{
import mx.controls.Tree;
import mx.controls.listClasses.IListItemRenderer;

If I set the properties of "buttonMode" and "useHandCursor" to true in DataGrid, it does not work as I expect. Only if I move the cursor to the edge between two rows, the hand cursor displayes.
What I expect is that no matter where the cursor is moved, it should always show hand cursor.
The following the itemRenderer:

I'm creating a custom component (based on ComboBox) and overriding some base methods. Recently I've found it acts weird when I set it's width in percents, rather than a fixed width. It tends to continuously call the commitProperties method and fail in the end. When I set it's width to fixed value - all works like a charm. What am I missing to implement? Here's some code ..
override protected function commitProperties():void {
super.commitProperties();

We use the FileReference component to upload file in Flex. But if the application is deployed within an environment having NTLM authentication (Windows Integrated Authentication), the upload capability will not work, and each time a message box will be popup asking the user to input credentials.I've queried some resource from internet and it seems this is a bug of FileReference component.

I'm a C++ programmer, but I'm a newbie in Flex. I'm developing a Flex 3 application for a social network using the FlashDevelop. For debugging I'm using the stand-alone FlashPlayer (10.3 debug) downloaded from Adobe. The application is a simple audio player which shows artist/album images.
The application worked properly on both local computer and remote server until I made some layout changes in Main.mxml. I added some HBoxes and changed Image placement. After that the application still works on my local computer, but it doesn't work properly after I upload it to a server.
Application buttons are not highlighted on over/out/click events, images loaded from the Internet are not displayed, text changed dynamically is not displayed, but when I click buttons a sound file is loaded from the internet and starts playing. It looks like some events which are responsible for components displaying are not dispatched, because some part of functionality not related to displaying still works.
To make sure that this is not a server problem, I rolled back to the previous revision. All works fine.
I suppose that this is a known issue, but I have no idea what is the reason.
