This patch implements man pages opened using the help url protocol
properly getting added to the navigation history as well as enabling
the back and forward buttons in such cases.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
Also moves WebContentClient and the references to the generated IPC
descriptions, since they are all components of OutOfProcessWebView.
This patch has no functional changes.
TabWidgets couldn't be used in GML properly, as the GML creation
routines didn't actually call the necessary functions in the TabWidget
to get a new tab added. This commit fixes that by making the name of the
tab a normal property, the previously introduced "title", which can be
trivially set from GML. Therefore, try_add_widget() loses an argument
(while try_add_tab doesn't, because it newly constructs the widget).
This allows us to get rid of the silly "fixing my widget tree after the
fact" code in Help and will make it super easy to use TabWidget in
future GML. :^)
Since the selection already gets updated in AbstractView::keydown_event
and AbstractView::mousedown_event we don't have to update it again in
the MainWidget::open_url function.
This fixes a bug that causes the selection to "spaz out" when
scrolling too fast between pages.
Up and down arrows now select search results. Matching index now
displays in full before filtering. Searching from the command
line focuses the query, and searches are now case insensitive.
Converts Help's layout to GML, propagates model and icon creation
errors, and switches to the MainWidget-namespace organization
pattern seen in more up-to-date apps like TextEditor to make things
easier to maintain going forward.
