OpenLaszlo community space at Assembla.com

rajubitter — Mon, 14 May 2012 10:07:45 GMT

Hi all,

I've created an Assembla team space for the community, which has chat
and discussion functionality, wiki pages, team and file management. We
can add SVN/GIT, bug tracking and other features, if we ever need
them.
http://www.assembla.com/spaces/openl...ommunity/start

The chat tool provides a searchable history, and can be found at this URL:
http://www.assembla.com/spaces/openl...nity/chat_tool

The space name and URL can be changed at a later point in time, if we
ever decide to fork OpenLaszlo.

If you want to become a member, send me an email to rajubitter [at] googlemail.com, and I'll send out an invitation to you.

Best,
Raju

proper way to set font of floatinglistbox in datacombobox

oneirosis — Sat, 12 May 2012 14:56:37 GMT

Setting the font attribute of the datacombobox doesn't set the font of the list elements in it's floatinglistbox.

What is the proper way to set this attribute without editing the laszlo foundation source code?

custom cursor broken in html5 OL5.0?

oneirosis — Thu, 10 May 2012 04:27:52 GMT

Is the custom cursor functionality broken in OL 5.0 html5 mode?

I couldnt get a simple example to work... then I realized that the Laszlo Explorer custom cursor examples only display the custom cursor for Flash builds and not HTML5.

Clear dataset

jorgeferes — Thu, 03 May 2012 17:13:53 GMT

Hello everyone!

How do I clear the information contained in a dataset?

Keyboard events

jorgeferes — Thu, 03 May 2012 12:28:23 GMT

Hello everybody!

I think I posted something similar before. Need to identify when the user is enabled with the CAPSLOCK key in the password field in my login screen. I could use LzIdle to capture the moment when he presses the button, but if the user already enters the progam with the key pressed, it does not address that.

And there's a problem that is LzIdle in their area. I can not make it work ONLY within the EditText, whenever I use the whole canvas has focus which triggers the event.

Does anyone have a solution?

Problemas com chamada JSP

jorgeferes — Wed, 02 May 2012 12:25:15 GMT

Hello, everyone!

I have a problem when performing a method of accessing the database. My situation is as follows:

I have a module on my system that manages the inventory of a clinic. After modifying the database, the program runs four searches to see if one of the quantities of the following has changed:

- Product below the minimum inventory
- Missing product
- Product expiration date for the next 45 days
- Product expiration date

To determine whether a change has brought some of these rules, I have a JSP that is invoked four times (once for each rule), updating four independent datasets. These datasets are linked to 4 edittexts (through the event Ondata) that update, make visible or invisible (through the event OnChanged) 4 warnings that have on the screen informing the user the status of the stock.

My problem is: when I call the method that the bank will count the items that fit the rules, my program starts to act strangely. If I comment the call to this method, it works correctly. I believe it is a conflict, but everything seems OK. Could anyone help me?

This is the method, it works correctly:

Code:

    

        popularDatasets(this.dataBaixa, 'baixa');

        popularDatasets(this.dataFalta, 'falta');

        popularDatasets(this.dataVencendo, 'vencendo');

        popularDatasets(this.dataVencidos, 'vencidos');

    



           

        
        var p=new LzParam();

        p.addValue("itens", itens, true);

        dataset.setQueryString(p);

        dataset.doRequest();

        ]]>

Does anyone know if tell me Openlaszlo supports multiple accesses to the JSP nearly simultaneously?

rajubitter — Wed, 02 May 2012 11:07:53 GMT

Hi all,

of the "25.000 member" former members of the OpenLaszlo community
(those were number which Laszlo has been circulating a while ago) 43
have filled out the survey, and I'm glad that we got more than 40
people participating. Thanks to all of you!

More than 56% / 25 community members have started using OpenLaszlo in
2006 or earlier, with 16% or 7 people coding OpenLaszlo since 2009 or
later.

Versions used by the community:
61% use 4.9, 41% use 5.0 trunk by now. But there are still people
using 3.3, 3.4 or 4.0 and 4.1 (probably existing apps which will be
upgraded at some in time - something which a few people seem to be
doing right now).

Runtimes used:
dhtml 70.5%
swf10 65.9%
swf8 22.7%
mobile (dhtml) 15.9%
swf9 11.4%

Most wanted future runtime/deployment target:
Android app 59.1%
iOS App 56.8%
Mobile runtime (tablets) 54.5%
SWF11 47.7%
...

Why people are using OpenLaszlo?
LZX language 69.8%
OSS 65.1%
Multi-runtime support 58.1%

Most popular editor / IDE:
Eclipse with Spket plugin 37.2%

OSS, contribution, committing
44.2 % have contributed to an OSS project in the past, and 44.2 % have
never done that. 11.6% have worked as committers on OSS projects.

Forums are the main communication platform, with 81.4% using the forums,

77% of the community have never personally met anyone from Laszlo.

Read the rest of the PDF for yourself I want to point your attention
to the user comments starting on page 27 of the PDF file, some of them
are very interesting. One company has developed an internal OpenLaszlo
IDE, and they might be willing to contribute that to the community!

Thanks again to all of you! Best regards,

Raju

Cannot disable hand cursor

kbriggs — Sun, 29 Apr 2012 20:24:47 GMT

The showhandcursor property seems to be broken in SWF10:

Code:

When this code is compiled to SWF10 in OL 4.9, the hand cursor displays over the entire dialog even though I have showhandcursor set to false.

When compiled to SWF8, it's only a hand cursor when floating over the button. Otherwise, it's a normal arrow cursor as it's supposed to be.

Hyperlinks in text no longer work

kbriggs — Sun, 29 Apr 2012 18:23:18 GMT

Upgrading a 4.1 SWF8 app to 4.9 SWF10 and I noticed that hyperlinks using the tag in a text element no longer work despite what it says in the docs:

http://www.openlaszlo.org/lps4.9/doc....html#d0e11086

The example shown has "OpenLaszlo" as a link. But clicking on it does not launch a web page unless you compile it for HTML, not Flash.

Is there some workaround? I have a dialog box that has user-submitted content like a newsletter and it needs the ability for them to insert links in various places as needed.

mouse events in loaded SWF app inside OL

Waterbottle2 — Sun, 29 Apr 2012 05:39:11 GMT

I'm using OpenLaszlo for a project since 4 years.
The last version I used was lps-4.9.0 before I tried
lps-trunk, provided by Raju recently (thanks again!).
I was able to load a full Flex application swf into the
OL app, which was not possible before. It works
in Flash 10 as well as in 11. When I compile and/or modify
the Application such that I get an SWC similar to the
Google Map approach, then it doesn't work. But that's no
problem for me if the SWF way works.

The problem:

OpenLaszlo seems to capture or block certain mouse events.
When I add the SWF into

myWindow.content.sprite (myWindow is instance of window class)

, most mouse actions work (e.g. Flex buttons), but some don't.
I observed further that when I add the SWF to

myView.sprite (myView is an instance of view)

, then the SWF does not react to ANY mouse events. That means
window is somewhat better, but not enough. I'm using

flash.display.Loader

for loading the SWF.

Does anybody know how to get all mouse events working for
the SWF?

Thanks!

Button bug #1009

kbriggs — Sat, 28 Apr 2012 18:28:46 GMT

I'm converting a SWF8 app compiled in OL 4.1 to a SWF10 app compiled in OL 4.9. I'm down to just a few minor bugs. Having trouble with this one that displays in the debugger at runtime:

ERROR @lz/button.lzx~95: TypeError: Error #1009

I have a button on a form with the isdefault property set to true. If I click the button directly there is no error displayed. It's only when I press Enter on the form that triggers the error. Even if I tab the focus to the button before pressing Enter or Space, the error displays. In either case, the button's onlick handler fires and everything works properly. I only know of the error because the debugger is running.

Line 95 in button.lzx points to a method called "showUp". I doubt the problem is in there, otherwise it would be happening to everyone. Although I did notice this line:

if (this.style) this. _title.setAttribute("fgcolor", this.style.textdisabledcolor);

There's a space between "this." and "_title". Is that allowed? I removed the space and recompiled but it made no difference.

Problems with dataset

jorgeferes — Thu, 26 Apr 2012 20:19:30 GMT

Hello again!

I have the following situation: I have 4 and 4 edittexts datasets (each EditText connected to a dataset using the parameter 'datapath'). At times, my program must update the datasets, thus changing the information in each field. The problem is that the field is only getting the return of the dataset only once, even if I call again the method that updates the dataset does not change the field. Could you help me?

fields and datasets:

Code:

    

    

    

       

       

    
    onchanged="parent.mostraAviso(this, canvas.barraLateral.containerGadgets.groupInformacoes.avisoEstoqueBaixo, ' abaixo da quantidade m�nima.')"/>

    
    onchanged="parent.mostraAviso(this, canvas.barraLateral.containerGadgets.groupInformacoes.avisoEstoqueFalta, ' em falta.')"/>

    
    onchanged="parent.mostraAviso(this, canvas.barraLateral.containerGadgets.groupInformacoes.avisoProdutoVencendo, ' a vencer nos pr�ximos 45 dias.')"/>

    
    onchanged="parent.mostraAviso(this, canvas.barraLateral.containerGadgets.groupInformacoes.avisoProdutoVencido, ' com data de validade vencida.')"/>

method that updates the dataset:

Code:

    

        Debug.write('atualizaAvisos() chamado!');

        popularDatasets(this.dataBaixa, 'baixa');

        popularDatasets(this.dataFalta, 'falta');

        popularDatasets(this.dataVencendo, 'vencendo');

        popularDatasets(this.dataVencidos, 'vencidos');

This method is called in the canvas oninit and every change in my database.

DHTML performance tip

oneirosis — Wed, 25 Apr 2012 09:38:25 GMT

Disabling GPU accelerated compositing on the browser may actually improve the performance of your application. GPU compositing acceleration is enabled by default in Chrome.

My laptop has an Intel GMA gpu which is notoriously dodgy in performance and after disabling it (add --disable-accelerated-compositing to the command line on Chrome) my laszlo app became impressively slick. :D
