Hi Antun,

Thanks you very much for pointing to application page (This is context my qposting name "Online laszlo application").

But most of these application are more sort of static page appilcation. I also know there are very good example and demos available on main home page as well.

I am very much newbee to laszlo, I wonder if every newbee faces the similar basic problem. What would be really helpful if we can one have demo applicartion that would more like portals, demostrating if not all but use of most general component like Grid, raiobutton , check box (may be use of these component in grid). Also it would be nice if that demostrate the navigation from page to page (like in JSP, PHP application)

I know initially I am asking for much but same time I assume it worth putting this effort to help the people who come from JSP , PHP backgroud to map there idea in Laszlo. Specially when no book available on laszlo (or I am aware of it).

Also I am sure this will help in reducing the number of newbee question.

I am happy to help in this regard in best possible way but at this moment I am short of knowledge to do it all alone. I am happy to share my application once it will up and running as exanmple.

Also as I asked in previous posting do you have any training programme in UK. In case yes I know the group of people who will intrested in attending going to one. We are from scientific research community and very happy to enbrace new technology like Open Laszlo.

Thanks you very much

What scientific research community are you with in the U.K.?

Have you read the documentation first?

Obvious question .. but do you know how to search the forum (from root) with keywords such as "php" ?

Here is one useful blog (http://weblog.openlaszlo.org/archives/2006/01/)

and another blog by Oliver Steele (http://osteele.com/archives/2004/12/serving-clients)

Hi

Thanks for poiniting me to blogs they are quite useful.

I am into Bio-informatics, specifically Microarray data analysis.

I have decent exprience in J2ee and related technology and trying to map it with Laszlo and for the moment finding it a bit hard to replace JSP from Laszlo. But I really appriciate the features of laszlo and inspite of all intial difficulties we want to implement it in our new project.

I have already gone through developers document as well as demo and sample code and able to develop some bits. Since in past I have exprience in seraching JAVA forums, I think i have fair idea how to do that, actually this is what I am doing for atleast weeks or so and finidng information in bits and pieces.

This is the reason I suggested the idea of having one demo application that coevers most general question asked by user is general suggestion , so that newbees could find it bit easier to adapt (till some book beocme available in market which covere all those aspects).

I would appreciate if some one could answer my naive question I posted before, in case neither this kind of application nor any training is scheduled in UK.

Thank you very much.

It always helps if we can understand your research interests.

I'm no expert, but as I understand, your apps (microarray data analysis) will require statistical analysis and visualisation.

I'm not sure that an openlaszlo + php + mysql demo will help you much, but here is one demo (http://www.laszlosystems.com/developers/community/forums/showthread.php?threadid=4661&highlight=php)

If 3D visualisation is required (visualising DNA structures) then you might look at SVG integration with openlaszlo (relatively virgin territory). But no demos (yet) on this forum!

Hi,

What you said is exactly right, it is statistical analysis and visulatization application. The demo example you forwarded was useful one but I already come through this far and succesfully connected to DB.

My specific problem is on GUI part. Although it looks very simple but finding bit hard to implement in Laszlo. I would like to tell you step by step:

1) First screen as login screen.
2) on succeessful login it goes to new page (in laslzo new view) with table having different coloumn (Experiment name, description...) all these values are coming from DB and one of column will be having radio button to allow user to select one of the experiment.

Problem : I am having problem in placing radio button in cloumn dynamically( also associating value of experiment_id with it) and putting in one "radiogroup".

I also want to have search facility on this so that user and search for specific type of experiment.

3) Ones user select one of experiment on next page I want to display list of files associated with this experiment which could be anythig 20-40 files.

This is just intial idea, I assume if I would be able to come this far, I would be able to cover basic of Laszlo and develop anything further.

I hope you would be able to help me out some way.

We are already working on visualtion part with help demos available, it is quite encouraging.

Thanks you very much

ideas on rendering CML deleted ..

Hi there,

I think maybe you are having difficulty mapping your know how with the demos you get from OpenLaszlo. Most of the demos uses static classes or objects. Eg. you create a class, say demoscreen. You will see your examples showing you to use the demoscreen tags <demoscreen> , instead of instantiating it as code.

I been working on a drag and drop application, with boxes flying all over the places , which the user will create dynamically . Lines too, joining the boxes, (with directional arrows). It is sort of like a MS Visio for us to draw flow diagram or something. I find that I have to code everything instead of using static objects. Also I will have to keep some dataset to flag events here and there.

Hope this helps

Hi Joshua,

It sounds quite close to what I am looking for.

Could you tell me where I look for the code you mentioned.

Cheers

Hi there,

I dont have the code right now to give you any snippet, as I am away from the office.

However,my plan was creating the objects I need , giving them the right attributes and behaviour.

Eg. diagram class .

Upon initialization of the canvas, some action on some view or buttons will trigger creation of diagram object instance. Eg. aDiagram = new diagram ()

I hope the syntax is correct for initializing the object. I havent been coding laszlo for few months, so its a little rusty off the hand.

Maybe you want to share more about how you want to achieve what (with more details), and I will see if I can provide you good advice on that.

Thanks for Idea, I will try with this.
