RE: [flexcoders] can't make Zoom+Rotate work in Parallel
Jason,
This is a common problem in Flash as well. The solution is to nest the
object you want to scale within a parent object which you then rotate.
Try this:
?xml version=1.0 encoding=utf-8?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
layout=absolute
backgroundColor=white
mx:Button label=parallel click=parallel.play()/

mx:Button x=200 label=reset click=c.x=200; c.y=200; c.rotation=0;
p.x=0; p.y=0; p.scaleX=1; p.scaleY=1;/
mx:Canvas id=c x=200 y=200
mx:Panel id=p width=100 height=100 x=0 y=0/
/mx:Canvas

Should it not put the cursor into the textArea and have the 10th through 20th characters selected? Even if you select a range of text with the mouse you will not see the blinking insertion cursor in the textarea. What matters is that your app has focus so that it can receive keyboard actions.

The problem is getting the poetry to layout on the page right. I sure could use some tips on this. I have an Accordion wrapped in a Panel container. That's not the issue. The issue is the actual text block that holds the text of the poems. I have in mind either: mx:Text mx:text Line 1, Line 2... ... /mx:text /mx:Text or mx:Text mx:htmlText ![CDATA[ Line 1, Line 2... ...]] /mx:htmlText /mx:Text Neither of these really works so well. When you use the CDATA block, well, it counts every space, whereas regular html would ignore the extra spaces. Theoretically, this is doable but it would be very sloppy. I'd have to run it all together like this: Line 1br/Line 2br /Text for line 3br/.. Even that doesn't work because as soon as you hit the return key, that throws off the formatting and layout. Using the first option makes it impossible to have any control over how the lines break. Using the regular text tag runs everything together as a paragraph. So, far, as I thought of this, it seems that the only option is to put the text of the poem into an image. So, then I'd have inside each accordion panel an image or two images that contain the text of the poems (two images if I wanted two columns for the display of the poem. Can anyone think of anything else or any other ideas for this? I'm open to other suggestions for laying out a poem in Flex. I saw this FlexBook that gave me this idea. The FlexBook would take some time to accomplish so I thought I'd try something easier first as I'm still new and want to add to my skills and accomplishments in Flex. In that FlexBook, it seems that every page is an image. So, maybe that is how you have to layout pages of text when you want it to look just so. I do welcome suggestions as to how I might approach this. Thanks, Bruce Bruce Whealton

Hi,
I recently did something like this. But it was more complicated because
I was loading a swf from a different domain from it's parent. I needed
to attach an event handler to the swf when SWFLoader was done loading.
Then at some point, the loaded swf would broadcast an event, and the
parent swf would be able to respond.
Contrary to what the last poster said, I think you should consider
listening for the Event.INIT, not Event.Complete broadcast by your
SWFLoader. To determine which one you need, check descriptions of these
two events in the Flex 3 Language Reference. Here's the meat of it:
INIT is broadcast when the properties and methods of a loaded SWF file
are accessible.
COMPLETE is broadcast when content loading is complete.
So, if you need to be able to access child movie clips, I'd say use
INIT.
Here's some code. Please note that both parent and child are Flex
applications, yielding parent.swf and child.swf.
In parent.swf:
mySwfLoader:SWFLoader = new SWFLoader();
mySwfLoader.addEventListener(Event.INIT, onInit);
function onInit(event:Event):void
{
mySwfLoader.content.addEventListener(myEventName,
onMyEventHandler);
}
function onMyEventHandler(event:Event):void
{
//do something
}
In child.swf:
//broadcast events that parent.swf can respond to.
systemManager.dispatch(new Event(myChild));
I found that when loading a Flex generated child.swf,
mySwfLoader.content is a reference to the child.swf's systemManager
property. So in order to broadcast events from my loaded swf, you
needed to dispatch the event using the child application's systemManager
property. Hence the last line of code.
Hope that helps.

Subject: [flexcoders] SWFLoader: access its contents right away
Hi all,
I am new in this group, so hello to everyone :-)
I want to discuss here about SWFLoader component in Flex 3, and how to
access their contents... programatically.
Just for short:
I have an existing, empty SWFLoader object in my MXML code.
After some time, I just want to populate it using SWFLoader.load()
method with an external SWF movie, that has child MovieClips inside.
Right after call the .load() method, I am insterested (in the same
function) to access its children to move positions, etc. So, if I do
something like:
var myloader:SWFLoader= this.swfload;
and then
myloader.load(shelf2.swf);
and then
myloader.content[s2].alpha=0.3;
It does not work at all. I tried myloader.addEventListener(...) with
several events, does not work.
The only way was to put that myloader.content[s2].alpha... inside
a setTimeout function, to allow SWFLoader to take some time to load.
But you agree with me that this is so dirty.
any ideas? Thanks to everyone!

RE: [flexcoders] Flex TextArea Limited by number of lines.
My approach is to simply reject any change that would exceed the maxLines
setting.
The following is presented sans the requisite class structure.
Create a component that extends TextArea, then:
var tf:TextField = TextField(this.textField);
var maxLines:uint = 5; // however many lines (getter/setter)
var storedInput:String = ;
private function onChange(event:Event):void
{
if (tf.numLines maxLines)
{
tf.text = storedInput;
}else{
// Handle editable TextArea bugs
storedInput = tf.text;
}
}
Issues:
There is a bug in the TextArea component (editable=true) where any given
line will fail to wrap so long as the last character in the line is a space
(also, the insertion cursor disappears beyond the right edge of the field.)
But this can be managed.
Using htmlText just makes a mess (the insertion cursor has a mind of its
own.)

This hasn't been a common request. What is your use case for allowing a user
to type up to, say, three lines but no more? Most UIs I've seen limit the
number of characters you can type, not the number of lines.
I think you have two choices: use the 'textInput' event to limit the amount
of text that goes in, or use the 'change' event to remove excess text that
has already gone in.
Which are you trying, and what problems are you running into?

I haven't looked at your code too much but what jumped out at me is this
line...
filterData = filterData.(attribute(prop.name) == prop.value);
This will try to evaluate attribute as a function with parameter prop.name
and then compare that to prop.value returning a boolean. So, the upshot is
that Flex will try to evaluate filterData.true or filterData.false. I'm
pretty sure that won't work.

You could use new Date(dateStr); However, if the date string contains hyphens it will be invalid and fail. If the hyphens in the date string are not under your control then you can swap them out for nice valid forward slashes: var dateStr:String = 2012-11-21 11:11:00; dateStr = dateStr.split(-).join(/); var doomsDay:Date = new Date(dateStr); Regards, Keith Reinfeld Home Page: http://keithreinfeld.home.comcast.net/ http://keithreinfeld.home.comcast.net From: flexcoders@yahoogroups.com [mailto:flexcod...@yahoogroups.com] On Behalf Of powers Sent: Tuesday, November 17, 2009 1:58 PM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] Comparing Dates: ObjectUtil.dateCompare not working @Keith What would you recommend to use instead of DateField.stringToDate to parse a string into a date object so that it doesn't strip off the time portion?

RE: [flexcoders] TimeZone issue
Ivan,
Is there any way we can get the Timezone selected by the user in the
operating system from running Flex application?
The short answer is no.
720 minutes after UTC can mean Auckland, Wellington or Fiji
The above is only true when Auckland, Wellington is not on Daylight Saving
Time (DST,) -- since Fiji does not observe DST, and that, I suspect, is
the real issue.
You can use getTimezoneOffset() to calculate many of the DST details of the
client machine. For example:
*/
// Test for local DST
public function hasLocalDST():Boolean{
var y:Number = new
Date().getFullYear();
var s:Number = new Date(y,
0).getTimezoneOffset();
var e:Number = new Date(y,
5).getTimezoneOffset();
if(s != e){
// DST is
observed
return true;
}else{
// DST is
not observed
return
false;
}
}
Similarly, for locales that observe DST, you can work out exactly when DST
starts and ends, whether the locale is in the Northern or Southern
hemisphere, and whether the locale is currently on DST. All assuming, of
course, that the client machine's time settings are correct for the locale.

I want the game logic to be in a script. The script will take the form of a series of rooms, each of which can contain: . doors to other rooms . characters the player can interact with . things the player can pick up and use Any of these can have conditions on them. The condition can be expressed as: . Player must have (thing) in his inventory . Player must have at least X points . Player must have at least $Y money . Call function f That last seems to be a problem. I would like to be able to take a function name I've read from the script and call the corresponding function. Or, alternatively, the script can contain the name of a class which must contain a method named (for example) conditionTest. But I haven't figured out a way to convert a string to either a Function or a Class. Is there a way of doing this? If I were working in Javascript, I'd just call eval, but that seems to be forbidden in AS3, right? Can I do this? Or do I have to put all the functions I might want to call this way in an array, and look them up that way? Or what?
RE: [flexcoders] Function from string?
I would like to be able to take a
function name I've read from the script and call the corresponding
function.
Hi A. P. Damien,
As I understand it, you have existing functions which you want to call by
passing the name of a function as a string to a generic method.
By 'script' I take you to mean an external text source.
public function makeTheCall(s:String):void{
//use try/catch to handle errors
try {
this[s]();
}
catch(e:ReferenceError) {
//trace(s,e);
}
}
Do I have to declare the class 'dynamic' for this trick to work?
I don't think so.
Or is it always legal to do this from inside the class?
'Always' is a tricky word. The functions you want to call need to be in the
same Class in order for the 'this' keyword to work. The function's name and
the function name string must be an exact match for case and spelling.
Regards,
Keith Reinfeld
