Hello All,

I am newbie to openscales.

I have gone through tutorial on the site http://openscales.org/documentation/tutorials/index.html.
But I am searching for tutorial having significance and properties of
the each openscales control and tag along with examples.

Please suggest me some tutorials explaining controls and tags of the
openscales.


Thanks in advance,
Namrata

Hi,

The method I used to start learning is to download OpenScales. Load
up all the projects in Flash Builder, compile and run the FxExamples
project, and the AS Examples projects and start looking at the code.

The examples and the entire demo programs code is in the download.

Then if you still don't understand something, start looking at the API
reference, also included in the download. The comments there are
sparse, but you can also look at the actual source code of OpenScales,
after all it is open. Look at the constructors, and try to get into
the mindset of the designers of OpenScales, try to imagine the
problems they faced, and how they would organize and solve them.

Set breakpoints at class constructors and poorly understood methods,
and start to step though the code with a debugger to get a feel for
the temporal flow of the program. Change things around incrementally
and see the results when compiled and run.

To be honest this is how you should tackle any new software library
that you need to use.

And remember Google is your friend, try doing keyword searches in this
forum itself to see if anyone has had the same problem.

Tutorials are nice, but they are truly a luxury, they are more
designed to be a quick start to orient you in the right direction to
learn the library. You just can't expect there to be tutorials to
explain every feature of a given library. Unless there is a huge
community, and you are using a truly ubiquitous library. ;-)

Good luck.

Hi,

Thanks a lot for ur guidelines. 

Yes, I agree hack library is best way to learn it. But when having timing constraints, it is good have tutorials to save time.

Regards,
Namrata

Hi,

I've been thinking about starting a bit of a community effort to put together some tutorials on core concepts. What do you think would be the most useful stuff to cover in these?

In my opinion, theese could be interesting subjects:
- Styles, definition an use ingeneral; in particular, the use with markers
- The use of GetFeatureInfo
- Important concepts and examples of the different protocols: WMS, KML, etc.

Hi,

Thanks for contributing to OpenScales, community efforts are more than welcome in an opensource project.

Regardings tutorials: These are a great way for newcomers to get in a project. Feel free to write about any subject you see fit. What we mean by that is, as a end user, you have a more accurate look on what tutorials should be about. We will then integrate your tutorials on the website.

We also have some tutorials on the website that are not up to date with OS 2 (http://openscales.org/documentation/). Right now, our hand are busy working on OS 2.1.2  and OpenscalesGL. If you want, you can fix them up, it would be a great contribution too.

Thanks form the OpenScales team

Sounds good, I will write a tutorial or two when I have some time,
work is swamping me right now.

I also agree with Diego's suggestions for the most part.

But I think it would be best to focus on the OpenScales API itself,
not so much the various mapping protocols. If necessary, focus on
examples of how to use the API methods for configuring and requesting
map data using the protocols. Some links to other documentation
regarding protocols would be better I think. The OGSC docs are a
little dense. Anyone out there with links to better stuff? The
GeoServer user guide is nice.

But I strongly agree with Diego's suggestion on detailing how to use
the powerful styling capabilities of OS, and how to extend/create
entirely custom AS markers by extending or overriding OS drawing
methods.

lol I already helped out Namrata over GTalk. Maybe we should have a
dedicated thread or group for newbie Q&A. Or a permanent Q&A page/
thread?

Q&A is a great complement to tutorials. We should take some time to go through the mailing list messages and note the most asked question.

This is a great thread. Back in 2010 we put together a guide/demo for download here:

http://www.webmapsolutions.com/open-source-flex-gis-solutions

It seemed quite popular. Something like this using 2.0 might be useful.
