I was trying to ask if the js:Span's constructor and/or createElement get
called.

In an app I'm working on, the following is working for me:

http://ns.adobe.com/mxml/2009;
xmlns:js="library://ns.apache.org/flexjs/basic"
width="100%">









I'm done for today.   I guess if you are still stuck, just check it in and
I'll look in the morning.

Re: [FlexJS] Conditional compilation in user projects

No Alex,

the createElement only generates a  tag (the container)

I want the custom renderer to add inside the custom things
(span,...icons,...img,...)


http://ns.adobe.com/mxml/2009;
 xmlns:js="library://ns.apache.org/flexjs/basic"
 xmlns:mdl="library://ns.apache.org/flexjs/mdl"
 xmlns="http://www.w3.org/1999/xhtml;> <-- that's
the li with conditional compilation in MDL swc

<--- all this block is bypassed,
this is in MDLExample and is created by user






I get :

Widgets

but not

Widgetshello

or

hello

I expect the later and use a binding with data in MXML (i.e: {data.var1})

Is the Span's createElement getting called?  I would recommend using the
debugger watch the Span get instantiated and added to the renderer.

Re: Slow performance > 1000 objects

[gmanupnorth]

Thanks for all of the suggestions thus far. I removed the call to
setstylebut the performance is still poor.

The profiler so far has not been that useful, but I will keep digging
tomorrow.


Forgot to mention this project is locked on AS 3. The SDK is 3.6 I believe.

Thanks,

Gordon

Re: [FlexJS] Conditional compilation in user projects

[Carlos Rovira]

No, I'm saying that I put a  in the custom item
renderer and is ignored (not hello in html output )

I only get the  generated from createElement in the ListItemRenderer.

So the problem is how to get the components declared in customitemrenderer
outputs in html inside the  tag created in createelement() method

I don't think Container should really make a difference other than
Container and MXMLItemRenderer know about layout so it should size and
position children.

But it sounds like you are saying that the js:Span is just placing text in
the li and not creating a span?  I don't know of any code that would do
that, so I think you'll just have to debug into it.

Re: [FlexJS] Conditional compilation in user projects

[Carlos Rovira]

Hi Alex,

I changed ListItemRenderer to extend MXMLItemRenderer, but nothing changed
output is still:


WidgetsThingysSprocketsDoohickies

I don't have any issue with sizes and layouts. My problem is that I want to
nest custom HTML things, for example a , and I don't get any output
but the current  container and it's text...

Also, MXMLItemRenderer extends as well UIBase and not a "container" class
like Container or ContainerBase

Hi João,

Yes, this is true.  IMO, the call to setStyle should happen immediately
after addChild.  Calling it before addChild sets up a temporary object to
hold the styles.  Calling it after validation causes additional
invalidations.

The profiler will show any impact like that.

-Alex

Re: Slow performance > 1000 objects

[João Fernandes]

Alex, didn't tell me once about the order of the actions (setStyle,
addChild) would also impact? Cant' remember what was the order but styling
and adding it as a child would also force additional invalidations.

Regarding virtual layout, do the items need to be all visible at the same
time?
I would recomend to use as the most lightweight component as possible, does
your container need to be a mx:VBox? Couldn't he simply be a s:VBox
(doesn't have any styling)?

Even to optimize it further, instead of creating all those nested
containers, you could use a s:List with a custom layout do place your
lightweight items.

Damn autocorrect! But chocolate is nice as well.

Re: Slow performance > 1000 objects

[Justin Mclean]

Hi.

Probably not the main issue but this line were chocolate length every time 
through the list

> for each ( var item:SmartAgentVO in value.Children )

It usually faster to use the more verbose:
var length:int = value.children.length
for (var i:int =0; i < length; i++)

My guess would be this line slows things down:
assetComp.setStyle("textIndent",7);

But it better to run it through the profiler to see what is actually happening 
as it's often where you don’t expect.

Thanks,
Justin

Re: [FlexJS] Conditional compilation in user projects

[Alex Harui]

See MXMLItemRenderer.  You either want to have a default layout or assign
one.  A parent sizes its children and if no layout is specified the
children do not get size.  Check the DOM to make sure all of the elements
got created.

It could also be that the renderer itself doesn't have a good size.

Re: Slow performance > 1000 objects

[Clint M]

instead of list.addChild you might want to have a look at using an mx:List
or s:List with useVirtualLayout for that many items

Re: Slow performance > 1000 objects

[Alex Harui]

Run a profiler to see what is taking so much time.  It could be just
adding that many children, or it could be something each child does when
being added that could be optimized or deferred for later.

If it is just adding that many children, you could create an array of them
and add them in bunches over several frames.

Re: [FlexJS] Conditional compilation in user projects

[Carlos Rovira]

Ok, I follow your indications and created a ListItemRenderer ni MDL swc,
this will be the basic IR and outputs LI with appropriate MDL class.

Now, I want this renderer to be able to be customized on user project
(MDLExample), so to test I did:

http://ns.adobe.com/mxml/2009;
 xmlns:js="library://ns.apache.org/flexjs/basic"
 xmlns:mdl="library://ns.apache.org/flexjs/mdl"
 xmlns="http://www.w3.org/1999/xhtml;>








This is not working and I think is because the basic DataItemRenderer comes
from UIBase.
I tried in local to redo the inheritance and do this:

public class ListItemRenderer extends ContainerBase implements
ISelectableItemRenderer

(following what I see in Yishay AccordionItemRenderer (difference is that
one is extending from Panel)

But I can't get this to show:






How I can get that output?

Thanks

Slow performance > 1000 objects

[gmanupnorth]

This piece of code is causing significant lag in our UI and was looking for
suggestions on how to improve it. This builds up a list of approx 1400 items
and takes 35-50 seconds to finish.


AssetTreeChild is a custom component based on the VBOX AssetTreeChild.mxml

  


public function setAgentItem(value:SmartAgentVO):void
{
this.agentItem = value;
if ( value.Children!=null && value.Children.length>0 )
{
var assetComp:AssetTreeChild;   

for each ( var item:SmartAgentVO in 
value.Children )
{
assetComp = new 
AssetTreeChild();
list.addChild(assetComp);
assetComp.setAgentItem(item);

assetComp.setStyle("textIndent",7);
}
}
}

If this project is successful, we should expect many additional platforms.
If you see what happen to other projects out there like haxe, it's normal
that people coming would want maybe iOS or Android or whatever and that
people comes to implement this addition.

Re: Flex as an operating system

[Alex Harui]

The Marshall Plan still generally expects a one-to-one association of a
SystemManager with an Application.  Lots of Flex apps have a central main
Application that loads sub-Applications.  By default, the main and
sub-apps all have to be compiled with the same version of Flex otherwise
changes to API signature could cause a verify error.

The Marshall Plan provided ways for a main app and sub-apps to be built on
different versions of Flex (as long as the main app was on the newer
version than the sub-apps).

I don't recall any discussions about creating new instances of Application
and adding it to a single SystemManager.  The API allows for it, although
I'm not sure the lifecycle would.  IOW, if you do
"systemManager.addChild(new Application()), you might get an exception
from some code somewhere.

Could Flex be an operating system?  I suppose so, but it wouldn't be a
very modern one.  It would at best be more like Windows 2.  A single UI
thread, no serious multi-tasking, etc.  Flex can certainly be the "world"
that everything else appears to live in.  I think there are kiosks and
other "embedded" apps where the only thing you see on the screen is a Flex
app and you can't switch way to other things running on the underlying OS.
 I think folks call those "immersive experiences".  One person even wrote
a dashboard for a very expensive luxury yacht in Flex.  It caused serious
hand-wringing on our team as we worried there might be a GC bug that would
cause the app to die.

Re: Click event issues in Android build

[Josh Tynjala]

It might help if you could provide some example code that demonstrates the
issue on Android. If others can't easily run the code to reproduce on their
own devices, we can only guess what might be wrong.

By the way, have you tried connecting the debugger to the app while it's
running on Android? There might be a runtime error on Android only, and the
debugger can show you exactly where it's thrown.
