View 3 RepliesActionScript 3.0 :: Trace The Width (or TextWidth) Of Dynamic Text Box?
Sep 8, 2010I have a dynamic text box on my stage that is 400px wide. The text box is being populated with flashvars data from an HTML file and auto-sizes (myTextBox.autoSize = TextFieldAutoSize.LEFT) so it will display all content by expanding when the text spans over 400px. But when I trace 'myTextBox.width', it always returns '400'and when I trace 'myTextBox.textWidth' it always returns '0'no matter how much text I push into it through the flashvars.
This is because the trace is only tracing the previewed swf in Flash which has no ties whatsoever to the HTML file and flashvars.Therefore, when previwing the swf, my text box is always empty.The only way to see the content populating the text box is when actually launching the browser with the swf embedded in it.Because of this I cannot seem to be get flash to 'do things' based on the new width/textWidth values of my text box after it has been populated with the flashvars data from the HTML file.How can I get flash to detect the new width/textWidth of my text box after it has been populated by the flashvars data from the HTML file?

Jan 27, 2011I created a somewhat custom Spark button by doing the File > New > MXML skin and basing it on spark.components.button. The problem is that I need to add an extra text field to the button component and dynamically change that text...but of course, the property isn't recognized on a Spark Button.
Is there a simple way to add this field to my custom button skin & its property so it can be addressed? If not, is there a simple way to take what I've done and just extend the Spark Button? I can't seem to find any examples that show how to do it without writing it all up in ActionScript.

Flex :: 4 - Null-component - Checking If The Cancel Button Component In The Child Component?
Jun 23, 2011I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?
ActionScript 2.0 :: Assign String To MovieClip - TextWidth / TextHeight Become 0
Oct 18, 2004I create various movieClips with TextFields in them using the following function.
function AddLabel(Label,L) // create a MovieClip with a Text Field. {
obj = this.createEmptyMovieClip("mc" + L,L);
var tf = new TextFormat();
tf.font = "Arial";
tf.size = 12;
[Code] ....
Lets say that I use the above function with the following statement:
JimMC = AddLabel("JimVision",1);
Then I try to assign a string to the above movieClip with some embedded html like so:
JimMC.txt.htmlText = "This is my test < a href='[URL]'>link</ a>.";
When I try to run the above the results come out blank. When I list my variables I do see that my TextField is being assign the text and html code. What I also notice is that the textWidth and textHeight value become zero. Why my results are blank? Why do the textWidth and textHeight values become zero?

Flex :: Use A Custom Text Component To Show A Series Of Comments?
Apr 1, 2010I'm trying to use a custom Text component to show a series of comments. I got the original idea from:
[URL]
I've got the base case working but I am stuck with 2 problems I cant seem to figure out:
Since I am drawing around the text, the actual height of each bubble is greater than that of the Text field, as a result, the last bubble is always chopped off. I have tried explicitly overriding the height getter, and adding some padding, but I cant seem to get it right. You can see an example here: [URL] In my layout, I have 2 VBoxes (one nested inside the other). The first vbox shows a form where the user can enter a comment, and the second box has all the comments. In order to ensure that the scrollbars only show up on the second box, I set minHeight="0" on the nested VBox, but then for some reason, some comments' text is shifted to the right. You can see an example here (look at the first comment): [URL]
Rather than posting the code here, I've provided some links:

Flex :: Right Method For Modifying Text Content In Component Lifecycle?
Aug 25, 2010I have custom components which must adjust their text content based on space constraints. For example a component adds labels until there is no space, and then the content of the last label becomes "(x more)"
I do not have access to size of child controls before adding them. When in updateDisplayList, I make changes to the layout of the component, but for labels, lblInstance.text property fires events, which lead to updateDisplayList being called again. I know that updateDisplayList may be called more than once, but if there is a way to modify text without triggering events, that'd be really useful. For example, setActualSize method in UIComponent allows this kind of modification. Anything similar for text controls? Or do you have best practices for laying out and managing text content, in the context of custom Flex components?

View 2 RepliesJava :: Component For Displaying (>25MB) Text File In FLEX
Feb 6, 2012Flex front-end using AMF to Java back. Trying to read, in real-time, a file that is being written to. For example, a log. I'm using Java's RandomAccessFile class to read the "new" lines of the file and send them back to the UI as a byte array along with the byte offset to start reading from next time. Using an mx:List to display all lines of the text file. The problem I'm running into, is Flex, or Flash Player, running out of memory on mildly large files, >25MB. Is there any preferred method of displaying large amounts of text data in Flex that I'm missing? Or does Flex/Flash just handle this poorly and I'm basically screwed?
View 2 RepliesActionScript 2.0 :: Accessing (Nested) Component Properties From Class
Jul 29, 2009(Actionscript 2 btw - and actually cs4, not that it really makes any difference?) I have a class that instantiates a movieclip from the library, e.g.:
Code:
debugbar:MovieClip = thing.AttachMovie("debugbar", "debugbar_mc", 999);
So attaching it to the where ever "thing" is - could be movie clip or level0 or whatever, doesn't matter as "debugbar" is a private variable of the class. Now the important part - debugbar in the library is a movieclip that contains some components - buttons and textInputs. The problem comes when trying to access these components.
I would have thought that this would work:
Code:
debugbar.input_txt.text = "hello";
In order to set the text of "input_txt", the instance name of a TextInput component on the timeline of the movie clip (put there in author time). However, this does not work. Infact, I cannot access any specific "component" properties - they come back undefined. I can however set and retrieve MovieClip properties for the "input_txt", such as _x. However there is one added strange thing with this too - setting _visible to false doesn't seem to work (however perhaps a component by default overrides this).
I also appear not to be able to add event handlers to the component - at least for the usual component events. I tried casting it to a component, such as:
Code:
var temp:TextInput = TextInput(debugbar.input_txt);
trace(temp);
which gave "temp" as null.
However if you trace the thing itself without casting to what it is, it gives the path to correctly. It almost seems like the components are somehow broken when trying to access them this way - or that they cannot be accessed this way?
The thing is, I was able to access all of this before, when the code to do it was placed on the timeline (frame 1, the only frame) of the debugbar itself, where the components were child instances. This meant I could just reference them directly too - so input_txt rather than debugbar.input_txt , although that is probably largely irrelevant. I need to have it in a class though, as I need to pass in certain objects that need to be accessed by the mc.
