wxGUI: Add new location action to database node in Data tab

[lindakarlovska]

wxGUI/datacatalog: New functions download_location_interactively, create_location_interactively added. Also checking for location validation a bit changed, made more clear. After clicking on grass node, two options for creating and downloading location are avaliable.

There is no longer the above-mentioned error after the Creating of new location in data catalog but I tried out to Read CRS from a georeferenced data file and this does not work. Not sure whether my georeferenced file is weird or there is an error. I tested .tfw and .jgw files looking like this:

This is not a world file, it's any tif, shp, ....

Basic functionality works for me, but there is couple issues I tried to describe in the comments.

Additionally, I tried changing the database directory in the location wizard and that caused some confusion in data catalog. GUI freezes and in command line I got "LOCATION </tmp/nc_spm> not available...access: No such file or directory" where /tmp/nc_spm is a combo of the database from the location wizard and nc_spm is a name of the current loation, but in different database.

I made several changes and this problem addressed at the end of my "trying" and I was not able to reach the state you are describing. There are two cases. It works fine in case I add the new database I want to append in to datacatalog before creating the new location. If I do not add this database It does not react but It does not display any error. I need to have a look more deeply at this case.
But in both mentioned cases I get this message:

and no error after that.

These are additional comments based on your change and my further analysis.

The GUI currently freezes if you attempt to change the db in location wizard first page. That's probably because it switches the db in OnWizFinished. It should be enough to remove the g.gisenv call from there.

Since the db can be changed in the wizard, you need to search the tree for the requested db and if the node is not there, you need to add the database to the tree..

I am not sure where to search the tree and eventually add the node is not there. I think it should be in OnWizFinished function but I need to make tree object in init here and I do not know how. I made suggestions in the past commit which do not work.

I would like to ask you several things, the best would be a video call on Monday 21 CET? What do yout think?

You search the tree in tree.py. Use SearchNodes functions, plenty of examples in tree.py.

Now, it should work.

Awesome. This works for me as expected. Can you please go through the comments and make sure they are all addressed and comment on them how they were addressed?
