This required some big overhauls. The view model no longer takes records. It only takes the date that it is responsible for, and it will ask the database for records pertaining to that date. This means that once the view model has saved all of its records, it can simply reload those records from the database. This has the effect that as soon as the user moves from DayEdit back to DayDetail, all of the interesting information has been repopulated.
These structures handle parsing and rendering of a Duration and a Distance, allowing that knowledge to be centralized and reused. Then I'm using those structures in a variety of places in order to ensure that the information gets rendered consistently.
This sets up a bunch of callbacks. We're starting to get into Callback Hell, where there are things that need knowledge that I really don't want them to have.
However, edit fields for TimeDistanceEdit now propogate data back into the view model, which is then able to save the results.
This adds the code to show the new records in the UI, plus it adds them to the view model. Some of the representation changed in order to facilitate linking UI elements to particular records. There are now some buttons to create workouts of various types, clicking on a button adds a new row to the UI, and it also adds a new record to the view model. Saving the view model writes the records to the database.
I've created the view model and added a getter function for the weight.
I'm passing the view model now to the DayDetailView, DayDetail, and
DayEdit.
I'm starting to set up the Save function for the view model, draining
all of the updated records and saving them.
None of the components yet save any updates to the view model, so
updated_records is always going to be empty until I figure that out.
DayDetail, the component, I used to use as a view. Now I'm swapping
things out so that DayDetailView handles the view itself. The DayDetail
component will still show the details of the day, but I'll create a
DayEditComponent which is dedicated to showing the edit interface for
everything in a day.
The swapping will now happen in DayDetailView, not in DayDetail or an
even deeper component.
This is a super tiny data structure that covers an edit mode, a view
mode, and an unconfigured mode. It's mostly a container so that views
don't have to preserve everything directly.
I move the weight edit view into the validated text entry widget, and I
work on some of the unfortunate logic in the weight blur function. I've
left behind a lot of breadcrumbs for things that still need to be done.
Swapping is now done in dedicated functions instead of a big pattern
match.
After selecting a database, the app window will apply the configuration
by opening the database, saving the path to configuration, and switching
to the historical view.
This allows me to directly reference functions that occur on those
widgets without losing them behind a gtk::Widget upcast or needing to
later downcast them.
