In order to correctly implement the week grid, we must
have a fast and optimized data structure to handle date
intervals.
This commit introduces, then, GcalRangeTree. The range tree
is an augmented AVL tree designed to handle intervals (i.e.
ranges) rather than single-dimensional keys.
It is a very good struct since common operations like insert
and removal are O(log n). It also is optimized for the ranges
we work on, so the nodes only take up the absolutely minimum
space required.
I'm simply too tired to split them off in separate commits,
so let me explain here. This commit:
* Remove debug messages
* Fixes many off-by-n and const-mistakes
* Simplifies the code
The current code does not move the remaining events up and,
when changing the week header various times, it ends up
showing completely bogus events at bogus positions.
Fix that by properly moving events up when removing them.
Instead of using a single, giant GList to store all the available
events, use an array of sorted GLists.
This commit adds temporary debug messages, beware the huge output.
By moving the drawing area to a separate place, we're
able to avoid having to manually calculate the sidebar
width.
Also, because we can, the drawing code was simplified a
little bit by moving the bottom border to CSS.
If the header is a GtkScrolledWindow, all the content
(including the top labels and week names) are scrolled.
This is a wrong behavior, since only the events should
be scrollable.
Fix that by making GcalWeekHeader a GtkGrid, and adding
the scrolled window in the correct position.
It looks like the cursor at the "Notes" section of the
edit dialog has no vertical space to breath, and it's
a little bit annoying as it runs away from the expected
position.
Fix that by adding a small margin at the top and the bottom
of the text view at the "Notes" section.
If we scroll to a month that has no event widget to
display, the redraw is not dispatched and looks like
Calendar is broken.
Fix that by always queuing a redraw.
Instead of using the old GLib boilerplate code, use the new
utilities and simplify the code a little bit. This also allows
us to remove the private field of month view.
Following the previous work on month view, this commit
implements scrolling capabilities to Year view. We do
this not only with the :scroll-event, but also using the
:edge-overshot signal of GtkScrolledWindow.
It is very natural and intuitive to try and change the current date
by scrolling. The current implementation of the Month view, however,
blatantly ignores scroll events.
Fix that by hearing to the scrolling events and changing the month
when the scroll is enough.
When the event widget's GdkWindow receives an event scroll,
the event is lost because it doesn't handle it. It should,
however, propagate the scroll event so that the container
is able to properly parse it.
Fix that by making GcalEventWidget listen and propagate
scrolled events.
Since now we manually manage the headerbar title and subtitle, setting
them via GtkHeaderBar API won't have any effect.
Fix that by directly setting the subtitle label.

If the user tries to drop a e.g. file, GNOME Calendar crashes
immediately.
While the desired behavior would be checking if that's an ics file,
lets just not crash for now.

When the user starts a drag operation from the overflow popover,
it should hide itself, otherwise it can block dropping the event
below it. Currently, this is not what happens.
Fix that by making the overflow popover a drag and drop target,
and hide it when it detects drag movement.

Since we need to special-case the datetimes to deal with UTC
all day events, using a general local GTimeZone would cause
the cloned all-day events to show wrongly inside the popover.
Fix that by calculating each event's start and end dates according
to the all day events.

To keep the current date chooser in sync with
GNOME Shell, tweak the week names to show only
the first, upcased letter of the week name.
Also, this commit avoids making day number circles
ellipses when the week number is not present.
The current implementation of the new calendar widget
accepts showing the week numbers in a modern and much
more consistent way.
The behavior, however, is not aligned with the rest of
the application and the desktop, which share a setting
to show or hide the week number.
Fix that by synchronizing the new calendar's week number
property with the specific setting.
After making the date selector use the brand
new date chooser widget, it is now time to make
it an entry.
This commit, then turns GcalDateSelector into a
GtkEntry subclass, and add all the plumbing that
is necessary to make it work as such.
As a side effect, this commit adds rudimentary
natural language support for parsing dates.
After adding the new GcalDateChooser widget, change the
current date selector to use it as the internal widget
of the popover.
The next logical step is turning GcalDateSelector into
an entry.
This is mainly a copy-paste from an old branch authored
by Matthias Clasen. The code style was updated to match
Calendar's one, and the theming was improved a little bit.
