If a key is pressed when the media player is in focus, which causes the
media player to perform some action, that key event is no longer
propagated further.
This will be used by the inspector, for showing style sheet contents.
Identifying a specific style sheet is a bit tricky. Depending on where
it came from, a style sheet may have a URL, it might be associated with
a DOM element, both, or neither. This varied information is wrapped in
a new StyleSheetIdentifier struct.
Calls to `Document::set_needs_display()` and
`Paintable::set_needs_display()` now invalidate the display list by
default. This behavior can be changed by passing
`InvalidateDisplayList::No` to the function where invalidating the
display list is not necessary.
Otherwise, it looks a bit awkward where the cursor position does not
update while the selection is elsewhere.
Note that this requires passing along the raw selection positions from
`set the selection range` to the elements. Otherwise, consider what will
happen if we set the selection start and end to the same value. By going
through the API accessor, we hit the case where the start and end are
the same value, and return the document cursor position. This would mean
the cursor position would not be updated.
The test changes here more closely match what Firefox produces now. It
is not a 100% match; the `select event fired` test case isn't right. The
problem is the event fires for the input element, but we most recently
focused the textarea element. Thus, when we retrieve the selection from
the input element, we return the document's cursor position, which is
actually in the textarea element. The fix will ultimately be to fully
implement the following:
https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#concept-textarea/input-cursor
That is, each input / textarea element should separately track its own
text cursor position.
And add tests! This implementation closely follows the current C++
implementation, replacing macros and gotos with a slightly more
complex state machine. It's very possible that an async version that
yields tokens on "emit" would be even simpler, but let's get this
one working first :).
Also give the Swift.String init routines an explict label when
constructing from AK String types, as this caused issues in a later
commit to have them both with `_ data`.
In particular, there was an assertion failure due to the temporary
parser document's "about base URL" being empty when trying to "parse a
URL" during parsing.
We fix this by copying the context element's document's about base URL
to the temporary parsing document while parsing a fragment.
This fixes a crash when loading search results on https://amazon.com/
At the same time, simplify CMakeLists magic for libraries that want to
include Swift code in the library. The Lib-less name of the library is
now always the module name for the library with any Swift additions,
extensions, etc. All vfs overlays now live in a common location to make
finding them easier from CMake functions. A new pattern is needed for
the Lib-less modules to re-export their Cxx counterparts.
For both types of elements, `.selectionStart`, `.selectionEnd`,
`.selectionDirection`, `.setSelectionRange()`, `.select()` and the
`select` event are now implemented.
Previously, only DOM nodes with `is_editable()` allowed selection via
the mouse. This had the unwanted consequence, that read-only
input/textarea elements did not allow selection.
Now, `EventHandler::handle_mousedown()` asks the node's non-shadow
parent element over the new virtual method `is_child_node_selectable()`,
if selection of the node is allowed.
This method is overridden for `HTMLButtonElement` and
`HTMLInputElement`, to disallow selection of buttons and placeholders.
Fixes#579
The spec requires that "multipart/form-data" Content-Type headers also
include a boundary directive. This allows the content server to validate
the submitted form data.
Google Lens, for example, rejects forms missing this directive.
When scripts receive a DataTransferItem from any IDL method, the spec
requires we return the same DataTransferItem for a particular item in
the drag data store. Meaning, we cannot just create these on the fly as
needed.
To do this, we store a list of DataTransferItem on the DataTransfer
object. We will return one of these objects any time one is requested by
a script.
It feels a bit weird to have the DataTransfer object store: the drag
data store, a DataTransferItemList, and a list of DataTransferItem. But
this is how other engines implement this as well. It basically has to be
this way as DataTransferItemList is just a proxy to the DataTransfer -
meaning, DataTransfer is the source of truth for all IDL access.
A DataTransferItem is associated with a DataTransfer, and points to an
item in the drag data store. We don't yet support removing items from
the store, but when we do, we will clear the index stored here to set
the DataTransferItem's mode to "disabled".
