add a GUI for entering geographic information

[mfrasca]

Actual behaviour

currently, you need to enter coordinates and distances numerically, for example when I enter the coordinates of placement of a plant, I have to first do this on a map, extract the coordinates (possibly in a spreadsheet), import it in ghini.desktop.

Expected behaviour

I want to specify the position on a map. something like, when entering plant data, having a button that opens a map, centred on the garden, and lets me specify the precise position by clicking on the correct spot.

let's see if others have other options, on stackoverflow. at the time of writing, the only answer only gave web-based solutions.

an other option, and the code looks quite neat, is to use LibChamplain, but it requires Gtk 3.0, and that is incompatible with PyGTK. the first big difficulty I experience in migrating ghini from PyGTK to Gtk3 is in the ComboBoxEntry, which disappeared in Gtk3.
Start by running this script, then see for yourself. https://raw.githubusercontent.com/GNOME/pygobject/master/tools/pygi-convert.sh http://dumbmatter.com/2012/02/some-notes-on-porting-from-pygtk-to-pygobject/

I've started parking work in a broken branch, called gtk2→3 and I'm adding a 'print' next to each line I'm commenting, just for the sake of letting the code run.

I guess this error is blocking it the infoboxes AttributeError: 'module' object has no attribute 'BuilderLoader'

@mfrasca Gtk.ComboBox with Entry still exists, it is integrated within Gtk.ComboBox itself, check https://lazka.github.io/pgi-docs/#Gtk-3.0/classes/ComboBox.html#Gtk.ComboBox.new_with_entry

[mfrasca]

@phastmike, the interface here is all in glade files, I don't think I can use that static function. … I'm more looking in the direction of the new glade equivalent to ComboBoxEntry, I think I wrote a small test case, let me look for it.

[mfrasca]

Looks like I had found something to work upon, but I've not yet processed it in the software: https://stackoverflow.com/questions/49941134/what-is-the-glade-equivalent-of-combobox-new-with-model-and-entry It doesn't yet cover the case in the software, where the pull down list needs to show more information than I want to accept in the Entry. The pull down list shows »Genus-epithet (Family-epithet)«, the entry only contains »Genus-epithet«.

[mfrasca]

GLib.Error: gtk-builder-error-quark: Unknown internal child: entry (6) is the error we get when I replace ComboBoxEntry with ComboBox and I don't put this block in it:

            <property name="has_entry">True</property>
            <child internal-child="entry">
              <object class="GtkEntry">
                <property name="can_focus">True</property>
              </object>
            </child>

then we have a combobox with an entry, if: isinstance(widget, Gtk.ComboBox) and isinstance(widget.get_child(), Gtk.Entry)

[mfrasca]

indeed there were more properties for which I need to use getter.

now this … GtkComboBox.text_column

[mfrasca]

moving to Gtk3 somehow makes reports from nosetests more readable: Exception sqlalchemy.exc.OperationalError: OperationalError('(sqlite3.OperationalError) no such table: history',) in <bound method PlantEditor.__del__ of <bauble.plugins.garden.plant.PlantEditor object at 0x7f0070385090>> ignored AttributeError: FakeGui instance has no attribute 'window' AttributeError: FakeGui instance has no attribute 'add_to_insert_menu'

[mfrasca]

good enough for starting to play with what is the title of this issue. and also good enough to start doing what @comradekingu was suggesting

[mfrasca]

[mfrasca]

you can type manually, or edit by opening the interactive map. if a value is already present, the circle and the two markers are added to the map, and the interactive map starts at the correct location and zoom.
