RE: [flexcoders] Re: Advise - List
Did you try it?. I'm pretty sure I can use Text or TextArea instead of
UITextField. I might have to call validateClient() on it after fixing
its width, but the key is to fix its width and then ask for its
measurements.
However, I definitely recommend using TextField over Text or TextArea in
renderers. It is much lighter than Text or TextArea.

Just FYI for anybody reading this thread, the reason it works when using
a UITextField and not mx:Text is that UITextField is not a UIComponent
and so updates its sizing and such as soon as it has a .width and a
.text

An example is in ListItemRenderer. Its internal textfield
handles wordwrap correctly. The OP could just use it, but it doesn't
handle html. I'd just copy the source and wire the listData.label to
the htmlText.

You mean this is causing measure() to report the wrong height
for the renderer itself? Wouldn't measure get called again once the text
component has layed out and worked out its height in a frame or 3?
What's the answer? Set text.width, call validateNow() before you use
text.height in renderer.measure()?
Intriguing :)

You can set it to 100%, or to a binding like:
vbox id=bar
text id=txt width={vbox.width}/
/vbox
Either will work just make sure that you set it :)
If you're doing that and it's not wrapping, you may need
collapseWhite=true (or something named like that) on your mx:Text,
depending on how you've set up your html!

Re: [flexcoders] Re: Advise - List
You could definitely do it, but you would have to call some sort of validateX() before you get a useful height, unless the height of the internal renderer is exposed via textHeight (which it probably is, now that I think about it). Haven't tried it, though. On Thu, Aug 7, 2008 at 4:04 PM, Alex Harui [EMAIL PROTECTED] wrote: Did you try it?. I'm pretty sure I can use Text or TextArea instead of UITextField.

[flexcoders] ActiveSupport::TimeWithZone
In the console, when I fetch updated_at from a record, and check the class via the command sim.updated_at.class I get ActiveSupport::TimeWithZone. Since it's a UTC time, I can use several of the commands from http://api.rubyonrails.org/classes/ActiveSupport/TimeWithZone.html#M0 00512 to convert this to the local time zone. In my Flex code I have a ComboBox that has a dataProvider which is an mx:XMLListCollection of sim items. When I choose one of those using the ComboBox, I want to take the updated_at value and convert it from UTC to the local time zone. However, none of the TimeWithZone conversion functions seem to work. For example, the statement trace(/ + userModelsCB.selectedItem.updated_at.getlocal + /) produces // in the trace file, as does everything else that I have tried. The commands work in the console, but not in my Flex code. If I just assign userModelsCB.selectedItem.updated_at to my text field, I get 2008-08-05T02:08:09Z, which is ugly and not very user friendly. Is there any way to get a TimeWithZone function that works in the console to work in my Flex code to get a nicely formatted date and time? Thanks, Louise

Problem is as soon as my client deploys on their company network the

[flexcoders] Checking swfs for malicious code!
Don't know if this is the right place for this, but thought I'd throw out the question before I dive headlong into building something that isn't do-able. Basically, I'm building a video player that would allow flash authors to create their own video/photo/game and upload to a server. My app would then take this and use it within the Main video player as they please. The concern my client has is that the swf's that are uploaded(AS3) may contain malicious code that might affect other users/websites etc... The main video players is built in Flex while the uploaded vids are done in Flash. Is there any way, other than decompiling swfs and checking the code, to determine if the code is in fact malicious from a swf? cheers erick

[flexcoders] XML Document and Navigation
Hello Everyone, I run into a problem, something that probably a lot of people here knows how to solve. But after sitting for 2 days building nestes for loops, i can't see the light by the end of the tunnel :-) So, here is a problem: I have to build an xml based navigation, so far, quite simple and clear. Made it already a few times, but, now, this is a bit more complicated, because i got a much deeper nested sub levels, and i really don't know how to efficient traverse the document and build the navigation out of it :| The most complex navigation i made had 2 levels, so it wasn't really hard to imagine the code for this task: 2 for loops done the nav creation and that's it, but i got now, an undefined deep, and i don't know how to bite the code that will build the nav, that goes a bit deeper then one- sub level. Do you guys got any examples or thoughts on how to solve the task? Im pretty sure that i got an logical error in my approach, since i will use some nested for loops, but i can't think the formula since i don't know how deep each of the nodes goes, and this task gives me headaches. any kind of help and pinpointing to right direction would be VERY appreciated cheers, Patrick -- fancy skills to pay the bills www.jankun.org Phone: +43 660 96 969 - 01 web:jankun.org mail: p[at]jankun.org

Re: [flexcoders] Re: Multiple Builder instances / windows?
Standalone, it's a packaged eclipse. Two builders == two eclipses I just went with builder because I prefer the way some menus are layed out and I don't do any java + flex (at the same time) development.

Now, how do I get at the menu item data that the context menu came from.
IOW, I left click on my menu bar which drops down a menu; I then right
click on a menu item (Let's say it is Show some Cool Stuff) which
brings up my custom context menu. I then left click on my custom

event which I have an eventListener for. The trouble is, there is
nothing in that event that lets me know what the original item was

[flexcoders] CursorManager problem - custom cursor disappears
Hi, I'm having this really weird problem in Flex 2.0.1 using LCDS ES 2.5.1 where whatever I do using CursorManager to change the cursor (like to activate the BusyCursor or any kind of custom cursor, no matter what priority) all my mouse pointer does is just disappear into nothing. As soon as I reset the BusyCursor or remove my custom one, the original regular mouse pointer image is restored. The thing that really drives me crazy is that standard component classes like mx.rpc.http.mxml.HTTPService make the same call succesfully! In the same application. I tried all kinds of workarounds, like employing callLater() so I could do the time consuming stuff from a separate function call (so the pointer will be updated), but that doesn't help. The mouse pointer is actually instantly updated but simply disappears instead of showing the different cursor. Any ideas on this? Did anyone ever had a similar experience? Regards, Ferrie

Hi, I have a multiline (HTML)text in a text control. When I select it and get beyond its last line/character and move further down the whole text will suddenly jump up one line, so the first line is not visible anymore. Is this a bug or is there a way to prevent this behavior (besides making the text non-selectable)?

It means mx.collections.SummaryObject does not dispatch events, therefore it can't dispatch PropertyChanged events, which is how bindings know that your data has been updated.

[flexcoders] Loading Stuff In Order - Advice?
Hi, I have a small application. A single view is declared in the main *mxml *file. This view loads some [remote] data upon initialisation. I rejigged the application so that it loads in a config file first (this config file contains the url from which I should load the data). Initially the config file didn't finish loading in until after my view's * initialization* event had fired .. so the view attempted to load data but threw an error. To solve this I plumped for declaring my view in MXML, but changing its creationPolicy to none, then calling createComponentsFromDescriptors() once my config had loaded. It works fine. I also realise there are various other ways to solve this (e.g. I could call my view's init() method manually, or I could add the view using ActionScript both being done after the config file had loaded). I wanted to post because I'm curious to find out how other people have been handling situations like this, and what arguments for/against your own methods you have become aware of (mainly because I think it could make a really useful blog post).

[flexcoders] Problems with nudgescrolling when programatically clicking items in DataGrid
Hello,
I'm writing some tools to automate clicking items in datagrids through
mouse events. Right now that means scrolling to an index, and calling
mouseDown, then mouseUp on datagrid.indexToItemRenderer(idx). The
problem is if the physical mouse cursor happens to be below the
datagrid when the mouseDown is called, the datagrid will nudge scroll
before the mouseUp is called if there's any delay whatsoever.
I don't want to necessarily disable nudge scrolling for the grid; this
is merely for automation purposes, so I was wondering if there was any
way on the fly to either force the mouse to move into the datagrid so
it won't nudge scroll, or to somehow disable nudge scrolling on the fly
quickly, so I can run the automation.
I've put together a simple (and poorly written, sorry!) app showing the
behavior. If you click the button, it dispatches a mouseDown event to
item 0 in the datagrid, then sets up a 10 ms timer. When that timer
fires, it checks if the item is still visible before firing the mouseUp.

[flexcoders] Tracking bytes loaded bandwidth usage on streaming videos
How can I track the amount of bandwidth used on a streaming video? For progressive download of video, we can say the user downloaded X number of bytes. However, if the video is streaming, there's no way for me to say X number of bytes have been downloaded/transfered/whatevered - at least not that I can find. Anyone have any ideas?

Re: [flexcoders] Where are the AIR resources?
It turned out to be an issue on my part. I figured it out and got it working.

Ok, so after all this discussion (thank you by the way) I came to the realization that what I needed to do is be running my Flex swf as trusted. So I moved it and all my in-house created support swf to the app directory so they are installed with the app. So far so good, as I already had support for loading my resources from a different path by setting a var in the embed code. Now I have a new issue in that when you hit Esc in my Flex swf I call both a ExternalInterface call and an fscommand to let the container know about it. I had it working where my hosting html page was getting these calls, but now it doesn't seem to be.

In theory I can compile a 'local' version, but there are some webservices that I would like to consume even on the desktop. Also, I don't think telling the user to trust the app-storage folder is a good solution. You mention getting it into the same directory as the main swf. Can you expand on that comment?

Once you truly trust the SWF bits, the next question is why your SWF needs network access. If it doesn't, turn it off and you won't get warnings. If it does need network access, I think your choices are to find a way load it into a trusted directory (users can opt to trust certain directories, or you somehow get it into the same directory as the main SWF), or proxy the network I/O or file system I/O through the main app. I don't think HTMLLoader or an intermediary HTML file is going to help. -Alex -- *From:* flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] *On Behalf Of *Steve Mathews *Sent:* Tuesday, August 05, 2008 10:48 AM *To:* flexcoders@yahoogroups.com *Subject:* Re: [flexcoders] Where are the AIR resources?

Next I have a Flex based swf that can actually run with these resources.

Actually obtaining the data isn't the issue. I more interested how do I go about comparing the old data to the new data? Array, some sort of custom hash, or xml. Which is faster or better?

[flexcoders] Different separator line colors on AdvancedDatagrid
Hello,
I want to draw horizontal separators between rows with different line
colors depending on the row data.
I tried to use optimized item renderers but the performance was still
too slow during vertical scrolling.
I also tried to extend AdvancedDatagridItemRenderer and set border at
true. But I couldn't choose border sides and I only want a border on the
bottom side.
Next I attempted to override the drawHorizontalLine method from
AdvancedDatagrid class:
drawHorizontalLine is called from drawHorizontalSeparators().
override protected function drawHorizontalLine(s:Sprite, rowIndex:int,
color:uint, y:Number):void {
if(indexToItemRenderer(rowIndex) != null) {
var myObj:Object = indexToItemRenderer(rowIndex).data;
var g:Graphics = s.graphics;
if (myObj.name == John) {
g.lineStyle(1, 0xff);
g.moveTo(0, y);
g.lineTo(width, y);
} else {
g.lineStyle(1, 0x00);
g.moveTo(0, y);
g.lineTo(width, y);
}
}
}
The first display is correct. But after a vertical scroll, horizontal
lines keep their position and are not redrawn no matter what the row is,
because drawHorizontalSeparators() is not recalled.
So I tried to call drawHorizontalSeparators() on Scroll event: failure,
separator lines on top and bottom rows disappear during the vertical
scroll.
Is there a way I can draw different horizontal separators depending on
data without using item renderers?
Thanks in advance.

[flexcoders] Compressing BitmapData
How can you compress BitmapData in Flash to reduce the amount of RAM it uses? I need to scrub H264 video frame by frame. You cannot do this utilizing NetStream.seek because it seeks to the nearest keyframe. This would require the video to consist of nothing but keyframes. Naturally this is not an option for file size and playback performance reasons. So, what I did was record a 10 second section of the video using BitmapData.draw ( t3hV1d30 ), shove the captures in an Array, and playback in a simple Bitmap swapper. It works well, allowing me to scrub frame by frame... ... except for the RAM; it takes 30 to 40 megs for just 10 seconds of 640x480 captures. Someone mentioned ByteArray.deflate. Looking for any ideas on how to reduce the RAM cost here??? -- sorry for the x-post for those on Flash_Tiger --
Re: [flexcoders] XML Document and Navigation
If you have to perform basically the same operation at each level of your XML, one way to deal with an open-ended number of levels is to use recursion. I apologize for not saying more, but I am running out the door, and don't have time to write up any kind of sample code on this. However, I'm sure that if you google for things like recursion or recursive function, you should find lots of information on how this approach works. I'd also guess that Wikipedia has a good article on this.

Re: [flexcoders] Re: Changing Parents
I may be wrong, but I have a guess here. First, you should not need your calls to removeChild. If you take an item that is currently in the display list, and use addChild to put it somewhere else in the display list, flex will automatically switch its parent from the old one to the new one. My guess is that this is what is happening: subcomponent. addChild( imageViewer) ; is doing what you wanted to, but app.removeChild( imageViewer) ; is then removing the imageViewer from the display list so that it disappears. Try just removing the calls to removeChild.

Subject: [flexcoders] Problems with nudgescrolling when programatically
clicking items in DataGrid
Hello,
I'm writing some tools to automate clicking items in datagrids through
mouse events. Right now that means scrolling to an index, and calling
mouseDown, then mouseUp on datagrid.indexToItemRenderer(idx). The
problem is if the physical mouse cursor happens to be below the
datagrid when the mouseDown is called, the datagrid will nudge scroll
before the mouseUp is called if there's any delay whatsoever.
I don't want to necessarily disable nudge scrolling for the grid; this
is merely for automation purposes, so I was wondering if there was any
way on the fly to either force the mouse to move into the datagrid so
it won't nudge scroll, or to somehow disable nudge scrolling on the fly
quickly, so I can run the automation.
I've put together a simple (and poorly written, sorry!) app showing the
behavior. If you click the button, it dispatches a mouseDown event to
item 0 in the datagrid, then sets up a 10 ms timer. When that timer
fires, it checks if the item is still visible before firing the mouseUp.

No one call can remove all listeners. No one call can remove all

If you add a listener on yourself, there is no need to remove it. It
might slightly help if it is a DRC object, but eventually it will be
garbage collected.
a.addEventListener(foo, b.someMethod) creates a reference from a to b,
not the other way around.

clicking items in DataGrid
Hello,
I'm writing some tools to automate clicking items in datagrids
through
mouse events. Right now that means scrolling to an index, and
calling
mouseDown, then mouseUp on datagrid.indexToItemRenderer(idx). The
problem is if the physical mouse cursor happens to be below the
datagrid when the mouseDown is called, the datagrid will nudge
scroll
before the mouseUp is called if there's any delay whatsoever.
I don't want to necessarily disable nudge scrolling for the grid;
this
is merely for automation purposes, so I was wondering if there was
any
way on the fly to either force the mouse to move into the datagrid
so
it won't nudge scroll, or to somehow disable nudge scrolling on the
fly
quickly, so I can run the automation.
I've put together a simple (and poorly written, sorry!) app showing
the
behavior. If you click the button, it dispatches a mouseDown event
to
item 0 in the datagrid, then sets up a 10 ms timer. When that timer
fires, it checks if the item is still visible before firing the
mouseUp.

RE: [flexcoders] Must call super.commitProperties at END of overrided commitProperties when extending TitleWindow?

Well, I said you were strict and not wrong. I've heard others say that super always should be the first thing in an override, but to me, that means that an override can only add or re-do and not intercept, which is, IMHO, a valid thing to do for an override. If you're that worried about whether you forgot or even intended to call super, a comment might be in order. Gordon likes comments whenever we deviate from a pattern like add a listener in capture phase. Sometimes I actually put them in.

I guess :) I just *really* don't like a situation where the position of super.whatever() affects whether or not it works. Frankly If I were designing a language super.foo() would be the default, and there'd be a keyword to block it. If super.commitProperties() can be expected to be anywhere inside a method, you can no longer at a quick glance tell whether or not it's called at all. The point I think is that commitProperties() is ideally (correct me if I'm wrong) for propagating any changed properties on this into their actual destinations, and deciding whether or not you need to schedule an updateDisplayList() or measure(). Doing anything else, such as changing said properties should be done where it makes more sense. The idea is that all the property changes generated by any events dispatched in the last frame are already completed by the time you get to commitProperties(). And changing properties inside commitProperties() invalidates this. It seems to me that whoever decided to ignore invalidateProperties() within commitProperties() thought something similar. That's probably an arrogant assumption to make, but I'm a jerk like that some times :) Somebody else in 6 months could see super.foo() at the end of your method, and because it's not in line with the rest of the project, move it back up the top - who knows how long it'll be before somebody notices that under certain circumstances the titles on your CustomPanel aren't what they should be any more? -Josh On Thu, Aug 7, 2008 at 11:15 AM, Alex Harui [EMAIL PROTECTED] mailto:[EMAIL PROTECTED] wrote: Man, you are strict!

[flexcoders] Re: removing default 1/1/70 label on DateTimeAxis
figured this out...
in the DateTimeAxis there is a method called buildLabelCache.
creating a class that extends DateTimeAxis and overriding
buildLabelCache like this:
override protected function buildLabelCache():Boolean {
var returnVal:Boolean = super.buildLabelCache();
if(labelCache.length == 1 labelCache[0].text == 1/1/70)
labelCache.pop();
return returnVal;
}
If there is only one label and it is the default label (from a Date
object with time=0), removing it from the labelCache so it never gets
created.

Is there a way to either make the whole axis invisible, or not show
any

I want to do this before I populate the chart, then when the data
comes
in, turn the visibility back on so that the 1/1/70 never shows.
[flexcoders] Re: Null reference after creationComplete()
Yes, but your dataGrid is in a child of a viewStack. It won't be
instantiated until yu change to that selectedIndex. You can use the
viewStack's creationPolicy=all. But, that's not usually best
practice. Better to just use binding. Instead of:
reportProjects.dataProvider = rptProjects;
do something like:
mx:DataGrid dataProvider={ rptReports }/
Assuming that rptReports is an ArrayCollection, this will wait until the
DataGrid is instantiated before setting the dataProvider.

Subject: [flexcoders] Problems with nudgescrolling when
programatically
clicking items in DataGrid
Hello,
I'm writing some tools to automate clicking items in datagrids
through
mouse events. Right now that means scrolling to an index, and
calling
mouseDown, then mouseUp on datagrid.indexToItemRenderer(idx). The
problem is if the physical mouse cursor happens to be below the
datagrid when the mouseDown is called, the datagrid will nudge
scroll
before the mouseUp is called if there's any delay whatsoever.
I don't want to necessarily disable nudge scrolling for the grid;
this
is merely for automation purposes, so I was wondering if there
was
any
way on the fly to either force the mouse to move into the
datagrid
so
it won't nudge scroll, or to somehow disable nudge scrolling on
the
fly
quickly, so I can run the automation.
I've put together a simple (and poorly written, sorry!) app
showing
the
behavior. If you click the button, it dispatches a mouseDown
event
to
item 0 in the datagrid, then sets up a 10 ms timer. When that
timer
fires, it checks if the item is still visible before firing the
mouseUp.

RE: [flexcoders] Re: Garbage Collection and event listeners
If you are the parent, adding an event listener to a child does not
create a reference to the child, it creates a reference from the child
to the parent, so it won't affect collection of the child when you
release all other references to that child.

Hi ron, In case you don't know, RMI is a Java thing. It is meant to allow methods of remote objects found in certain JVMs to be invoked by other JVMs. Just stick to AMF (which is what BlazeDS uses), or use Hessian, XML based Web Services or HTTP Services or JSON. I don't really think that it is worthwhile creating a new protocol, unless it does prove to be faster or better than the existing ones. Anyway, those are just my 2 cents. Fidel.

RE: [flexcoders] Re: DataServiceException
Yeah, it should be calling any fill methods which are still actively managed by
clients in that refreshFill call - as long as you have autoSync=true. There
are a couple of ways to track this down:
1) Put in this printSeq.jsp file (enclosed below) and request it. It will
show you all active fills, etc. If that is empty, somehow the client's fill is
not auto-sync'd.
2) If you turn on the Service.* debug target it should at least indicate
which fills it is trying to refresh.
