using embed.js in lzx application

Hi forks,

Can i use a functions, that contained embed.js file, in <canvas> ?
I mean as following

<canvas>
<script>
LzBrowser.loadJS( "../lps/includes/embed.js" );
</script>

<view>
<handler .....>
lzSetCanvasAttribute( ..... );
</handler>
</view>
</canvas>

If this work, it is possible to change the canvas attribute values while
a application working.
But dose not work it. Is there any tips or the canvas attribute can not
change after the application
has initialized ?

Thanks in advance

where to call javarpc methods before loading the page.

Hi,
        I have an Issue with the javarpc remotecall. I need to call a javarpc remotecall before loading the laszlo
page and I have to set that remotecall result(boolean value) to canvas attribute in remotecall function
ondata event. I have tried out to call javarpc remotecall in canvas onload, javarpc onload events, but it
is not solve my problem. Is their any solution for this issue?

Thanks,
Prasad Jorige.

Re: I am at the end of my rope

What David says makes sense.  It is how open source works.
But I think it works best when you already have a huge user base, which
doesn't seem to be the case for OpenLaszlo yet.
So what we have are relatively quiet mailing lists and forums.

I'm now evaluating whether I should jump into the world of OpenLaszlo and my
gripping fear is to be stuck in William's situation because there just
aren't enough fellow developers around to help.

I've talked to friends and we were all scratching our heads as to why
OpenLaszlo hasn't taken off like crazy, given how good it looks and the
head start it's had.
Smells like the classic chicken-and-egg paradox:
developers don't want to jump in until they see more developers around.

I'm afraid myself.  To be frank, I'm thinking right now
I'll just use OpenLaszlo for prototyping and then rewrite with some
of the up-and-coming AJAX toolkits, which are inferior to OpenLaszlo
but have a clear future thanks to a lot of hype and mindshare.

We all want OpenLaszlo to succeed of course.  It's an amazing and innovative
platform.  The question is when does the exponential growth kick in?

My two cents

Re: I am at the end of my rope

I'm evaluating OpenLaszlo right now for a small project; here's my
initial reaction, in respose to the question, "why is OpenLaszlo not
more popular?"

1. Look and feel
This is somewhat arbitrary: Although I like the overall slickness
(ease and quality of animation, etc.) of the GUI elements, I just
don't really like the way a lot of stuff looks.  In particular, I find
demos like the dashboard, well, kinda ugly.  I presume you can re-skin
widgets to look any way you like, but I'd personally like a prettier
look out of the box.  And maybe a little 'lighter'.  I can't really
articulate what I mean, but the look and feel seems 'heavy'.  I
realize that beauty is in the eye of the beholder, but that was my
initial reaction. And it was a bit of a turn off, though by no means a
deal killer for me.

2. Dislike of Flash
I'm not as anti-flash as some people, but I don't like the fact that
it often breaks the back button, right-click menu, etc.  And, for
example, in the Amazon demo you can't copy and paste any info
(sometimes that's useful).  I realize that Legals with a DHTML
back-end should address this issue, but my impression (again, I'm
taking the role of inattentive new developer here) is that it's not
quite yet ready for prime time.

3. Language feels a little alien
I started to mess around with some code, defining objects, etc.
Thanks to the really excellent documentation and demos, this was very
easy.  But then I wanted to make the appearance of a widget
conditional on the value of a user cookie (or some other variable).  I

Z,

Thanks.  I'll poke around the state and related tags some more.  After
my last post, I've convinced myself to poke around openLaszlo a bit
more.

Re: I am at the end of my rope

bcrounse,hi!

	1. the openlaszlo demo using "cool" skin just want to catch us eyes and make some visual effect,but in real
project, they(openlaslzo studio)or we never use such luxurious stuff.
see that:
http://www.surewest.net
http://www.openria.cn/main

    2. although,flash is not fit for everyone's taste,but,now, it is the only run time we could choose when
using openlaszlo, and if you wanna to copy and paste flash test, you can use inputtext control.

    3.many devolper say the lzx language is a little big "strange" and "alien",but this is just the feature of
openlaszlo,different from the traditional programming model, after all the language want to be a agile
develoment language.Also,you can find some infomation about your taget of "make the appearance of a widget
conditional on the value of a user cookie" at:

http://www.openlaszlo.org/lps/docs/guide/cookies.html
we have done the same task as your's getting http session infomation by using "dataset",it's src is a ".jsp"
file,so,this is not a big problem.

   some opinions of yours I agree, the platform's wide population and adoption need offical effort,because
people are new to OL need to confirm more relaibility and feasibility of it.So,more specific technical
articles and some consulting guides are strongly desired.That's just the shortage of Openlaszlo,also
the support of developoment community.

with regards

Experiment: LZX <-->haXe<-->AMFPHP

haXe seems to offer a useful bridge for linking OpenLaszlo to AMFPHP.

I have just imported a haXe compiled amftest.swf movie as resource into OpenLaszlo.

More here .. http://forum.openlaszlo.org/showthread.php?t=7927

Other classes in haXe API can work similarly with OpenLaszlo (including DHTML).

4.0 dhtml question

I'd like to add an iframe as a child of the content sprite in a laszlo
window. Right now my program looks kinda like this:

    <window name="mywin">
    ...

        var ifr = document.createElement( "iframe" );
        mywin.content.sprite.__LZdiv.appendChild( ifr );
        ifr.src = ...

If I try to this with a regular laszlo view, things work fine, but
something about maybe the masking or the styling is messing it up in the
window. I can see the request get made, so this is a display problem.

Any insight will be appreciated.

Thanks,
Adam

Hi Stefan,

Having a version of the proxy server that doesn't require Java
(swfload.php) will be super-great.  And it gave me a good excuse to put
up a wiki page documenting the LPS server protocol:

http://wiki.openlaszlo.org/LPS_server_API

As soon as we get 4.0 beta out the door we can write up more of the details.

It looks like you have enough to go on to proxy XML data requests.  It
would be great to add support for media requests - let me know if you
need more documentation or have specific questions.

And of course, please update and comment on the wiki as you see fit.

Also, I can link to your work from the appropriate wiki page(s) if you'd
like.  Thanks for the contribution!
