This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).
This commit is auto-generated:
$ xs=$(ack -l \bDeprecatedString\b\|deprecated_string AK Userland \
Meta Ports Ladybird Tests Kernel)
$ perl -pie 's/\bDeprecatedString\b/ByteString/g;

$ clang-format --style=file -i \
$(git diff --name-only | grep \.cpp\|\.h)
$ gn format $(git ls-files '*.gn' '*.gni')
This commit removes DeprecatedString's "null" state, and replaces all
its users with one of the following:
- A normal, empty DeprecatedString
- Optional<DeprecatedString>
Note that null states of DeprecatedFlyString/StringView/etc are *not*
affected by this commit. However, DeprecatedString::empty() is now
considered equal to a null StringView.
There is a bug in the "search by typing" feature of
AbstractView, where the highlighted text shown in items' title won't
match the search query if the search query contains whitespace.
This commit fixes that bug.
The bug is caused by a bad assumption made in
AbstractView::draw_item_text about the Painter::draw_text API.
Specifically that the function passed to it will be called for each
code point of the string instead of for each drawable glyph.
This is fixed by not relying on looking at the length of the highlight
string, but instead looking at its content.
Previously, If the widget was unfocused, the selection start index
would be invalid. This would result in invalid selections when doing
shift+click on the widget (while it is unfocused).
Now, we reassign the selection start index to current index
before we initiate multiselection, if selection start index is invalid.
Should Fix SerenityOS#11999 and the same bug inside FileManager.
Having a `Point`, `Rect` or `Size` claim it's `null` is silly. We have
`Optional<T>` for that. For `Point`, rename `is_null` to `is_zero` to
better reflect what we're testing. For `Rect` and `Size`, `is_null` is
removed outright.
Also, remove `is_empty` from `Point`. Points can't be empty.

This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
With a new DragCopy cursor icon being used on accepted events, this
caused a 'false assumption' that everything can be dropped into
AbstractView.
This will now only happen if the View is editable, which still isn't
perfect, but at least the Settings app will no longer change cursors.
Also note that we won't get "drag move" events as the comment below
says, which disables automatic scrolling when dragging an element.
Previously, during a m_might_drag mouse_up event, we were updating
the selection directly, which caused the selection to be accurate
but the location of the cursor index to be stale/incorrect. The
side effect of this is then future events may point to the wrong
index.
Instead, call the set_cursor function with SelectionUpdate::Set,
which handles both updating the cursor index as well as the
selection index.
AbstractView currently assumes a certain layout of rows and colums to
perform a range selection on.
This patch moves the implementation into a helper that can be overriden
by other views.
Previously using the highlighted_search would not set the cursor
to the item found by the search. This results in some unfamiliar
behavior such as jumping back up to the previously selected element,
before searching, when using the arrow keys to navigate.
This necessitates switching from passing a single code point to the
callback to passing a non-const Utf8CodePointIterator instead.
Note that the text selection mechanisms in LibGUI and LibWeb don't
handle this properly yet; they still assume that each code point
renders as one glyph. Similarly, width calculations for text widths
don't either, so a single such an emoji will require space for more
than one glyph.
It also doesn't work in LibVT's TerminalWidget, where each code point
is handled and rendered separately, so LibGfx never gets a chance to
check if subsequent code points could result in a combined emoji.
This adds automatic scrolling when dragging items in TreeViews and other
widgets that inherit from AbstractView when the overloaded
accepts_drag() returns true. This is implemented in FileSystemModel to
allow directories and files to be dragged.
This change splits the do_search() into find_next_search_match() and
highlight_search() to allow the given index be independently highlighted
when needed.
This makes IconView aware of the text width of the
ModelEditingDelegate widget when editing an index and allows us to
resize the content rect as needed.
This also removes the border from the textbox since it could collide
with the icon in ColumnsView. While editing we also skip painting the
inactive selection rect since it would otherwise show when the content
rect gets smaller.
Previously, moving the cursor over items in an item view would cause it
to repaint itself completely. Now we only repaint the two affected
items (the old hovered item and the new hovered item.)
Previously, if a drag operation was aborted by pressing the escape key
(handled by WindowServer), the drag would immediately restart if you
moved the mouse cursor before releasing the mouse button.
Since the introduction of multi-select, we have had both `on_selection`
and `on_selection_change`, the latter of which was only invoked when a
change in selection came in through the model.
This removes `AbstractView::on_selection` and replaces it usage with
the more explicit `on_selection_change` everywhere.

Modifying the selection while holding the shift button and selecting
with the mouse or the arrow keys no longer results in broken selections.
Fixes#6279.
I hereby declare these to be full nouns that we don't split,
neither by space, nor by underscore:
- Breadcrumbbar
- Coolbar
- Menubar
- Progressbar
- Scrollbar
- Statusbar
- Taskbar
- Toolbar
This patch makes everything consistent by replacing every other variant
of these with the proper one. :^)
Rather than invalidating the entire window, which is very expensive on
the transparent desktop widget, just invalidate the areas that actually
need updating.
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
AbstractView doesn't actually do anything with them anyway, but they
would get swallowed by the cursor logic and not bubble up the widget
parent chain.
