Thanks a lot for the helpful tip! Now it works. I updated my project on
GitHub:

Cheers,

Hi,
your map detection seems OK, this looks more like a problem with ExtJS
itself. Try
me.store = treeStrore; instead of me.setStore(treeStore);
since you call the parent constructor afterwards.
Cheers

Thanks for the hints.
It would be nice to combine the examples
(https://geoext.github.io/geoext3/) 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.
I already can access the map from my OverviewMap. See this file:
https://github.com/JakobMiksch/HelloGeoExt/blob/master/app/view/main/OverviewMap.js
If I try something similar with the LayerTree I receive errors like
"TypeError: viewConfig is undefined". Here is the code:
https://gist.github.com/JakobMiksch/b68276dd52bee8330ff5ab71fa238475
Could you tell why this approach works for the OverviewMap but not
for the LayerTree ?
Thanks and best regards,
Jakob

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.
The examples on http://geoext.org/ are nice and easy to understand,
but I find it challenging to convert the single file into the
proper folder structure of Ext.
you are right, that there are not so many example apps available,
which use the 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:
https://github.com/geoext/geoext2/tree/master/examples/app/simple
https://github.com/geoext/geoext2/tree/master/examples/app-mvvm
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: https://github.com/JakobMiksch/HelloGeoExt
Maybe we can use your "HelloWorld" app as example reference for MVC
/ MVVM app setup.
Not sure if this is a general Ext question:
But what is the "best practice" way to exchange the map and its
layers between the different components?
You can pass in the map or better a MapComponent, like
https://github.com/JakobMiksch/HelloGeoExt/blob/master/app/view/main/Map.js,
as config property of your own component. ExtJS will handle it like
a member variable in your instance.
If that is not possible for your whatever reason you can query
arbitrary component instances with Ext.ComponentQuery.query
(https://geoext.github.io/geoext3/master/docs-w-ext/#!/api/Ext.ComponentQuery).
So a
Ext.ComponentQuery.query('mappanel')
might be a helpful command. Even I like it more to pass over
dependencies as config.
Cheers
Chris
Is there any rather simple GeoExt based app that I could use a
template?
Cheers and have a nice weekend,
Jakob

Dear list,
I am getting into Ext and GeoExt and I am looking for examples where I
could learn from. I already found these:
https://github.com/terrestris/shogun2-client
https://github.com/OpenBfS/gis-client
and of course the tutorials:
https://github.com/geoext/geoext3-ws
https://github.com/geoext/geoext3/blob/master/universal-app.md
Could you point me to any other existing projects with GeoExt?
kind regards,
Jakob
