Thanks for the hints.<br>
<br>
It would be nice to combine the examples (<a
class="moz-txt-link-freetext"
href="https://geoext.github.io/geoext3/">https://geoext.github.io/geoext3/</a>)
into a "HelloGeoExt" application. This would make it much easier to
learn GeoExt. I would be happy if my app could be the basis for it.<br>
<br>
I already can access the map from my OverviewMap. See this file: <a
class="moz-txt-link-freetext"
href="https://github.com/JakobMiksch/HelloGeoExt/blob/master/app/view/main/OverviewMap.js">https://github.com/JakobMiksch/HelloGeoExt/blob/master/app/view/main/OverviewMap.js</a><br>
<br>
If I try something similar with the LayerTree I receive errors like
"TypeError: viewConfig is undefined". Here is the code:<br>
<a class="moz-txt-link-freetext"
href="https://gist.github.com/JakobMiksch/b68276dd52bee8330ff5ab71fa238475">https://gist.github.com/JakobMiksch/b68276dd52bee8330ff5ab71fa238475</a><br>
<br>
Could you tell why this approach works for the OverviewMap but not
for the LayerTree ?<br>
<br>
Thanks and best regards,<br>
Jakob<br>

Thanks for the link. I am actually getting started with Ext JS
and GeoExt at the same time. (maybe this is a bad idea ... ).
Understanding the BasiGX components is still a bit unclear to
me. And the web apps I mentioned earlier are very complex and
hence also hard to understand. <br>
<br>
The examples on <a class="moz-txt-link-freetext"
href="http://geoext.org/" moz-do-not-send="true">http://geoext.org/</a>
are nice and easy to understand, but I find it challenging to
convert the single file into the proper folder structure of Ext.

<p><font face="Helvetica, Arial, sans-serif">you are right, that
there are not so many example apps available, which use the </font>MVC
/ MVVM pattern. Most of the examples are simple single-file
demo-apps (like on the GeoExt website). Maybe a simple MVC /
MVVM app would be cool and we had that for previous GeoExt
versions:</p>

At the moment I am trying to build a pretty standard web mapping
application with a main map, an overview map and a layer
switcher. The overview map works, but I struggle to build the
layer switcher, because I do not figure out how to access the
layers from map. This is what I did so far: <a

Maybe we can use your "HelloWorld" app as example reference for
MVC / MVVM app setup.<br>

Not sure if this is a general Ext question:<br>
But what is the "best practice" way to exchange the map and its
layers between the different components?<br>
</blockquote>
<br>
<br>
You can pass in the map or better a MapComponent, like <a
class="moz-txt-link-freetext"
href="https://github.com/JakobMiksch/HelloGeoExt/blob/master/app/view/main/Map.js"
moz-do-not-send="true">https://github.com/JakobMiksch/HelloGeoExt/blob/master/app/view/main/Map.js</a>,
as config property of your own component. ExtJS will handle it
like a member variable in your instance.<br>
If that is not possible for your whatever reason you can query
arbitrary component instances with Ext.ComponentQuery.query (<a
class="moz-txt-link-freetext"
href="https://geoext.github.io/geoext3/master/docs-w-ext/#%21/api/Ext.ComponentQuery"
moz-do-not-send="true">https://geoext.github.io/geoext3/master/docs-w-ext/#!/api/Ext.ComponentQuery</a>).
So a <br>
<br>
Ext.ComponentQuery.query('mappanel') <br>
<br>
might be a helpful command. Even I like it more to pass over
dependencies as config.<br>
<br>
Cheers<br>

Is there any rather simple GeoExt based app that I could use a
template?<br>
<br>
Cheers and have a nice weekend,<br>

<pre wrap="">Dear list,
I am getting into Ext and GeoExt and I am looking for examples where I
could learn from. I already found these:

and of course the tutorials:

Could you point me to any other existing projects with GeoExt?
kind regards,
