This should keep the `read_some` function a bit flatter and shorter, and
make it easier to match the match type decoding process with the
specification.
1. Propagate calc() values from StyleProperties to ComputedValues.
2. Actually resolve calc() values when determining the used flex basis.
This makes the "support" section on https://shopify.com/ show up
correctly as a 2x2 grid (instead of 1x4). :^)
While inline content between floating elements was broken correctly,
text justification was still using the original amount of available
space (without accounting for floats) when justifying fragments.
This code now works in terms of *intrusion* by left and right side
floats into a given box whose insides we're trying to layout.
Previously, it worked in terms of space occupied by floats in the root
box of the BFC they participated in. That created a bunch of edge cases
since the code asking about the information wasn't operating in root
coordinate space, but in the coordinate space of some arbitrarily nested
block descendant of the root.
This finally allows horizontal margins in the containing block chain to
affect floats and nested content correctly, and it also allows us to
remove a bogus workaround in InlineFormattingContext.
This seems mostly harmless and matches what CSS expects from us at the
moment. Eventually our CSS font selection will become more sophisticated
and stop relying on Gfx::FontDatabase for things like this, but for now
it's a simple stopgap that lets websites do "font-family: arial" :^)
This allows for the browser process to control the play/pause state,
whether we paint user agent controls on the video, and whether the video
loops when it finishes playing.
This just sets up the IPC to notify the browser process of context menu
requests on video elements. The IPC contains a few pieces of information
about the state of the video element.
item_incurred_increase should be reset before every next distirbution
because otherwise it will accumulate increases from previous
distributions which is not supposed to happen.
Note that this simple form of text-indent only affects the first line
of formatted content in each block.
Percentages are resolved against the width of the block.
Fixes the issue when if there are enough rows/column to force
m_row_gap_tracks or m_column_gap_tracks be resized during gaps
initialization then pointers stored in m_grid_columns_and_gaps or
m_grid_rows_and_gaps become invalid.
Make a separate rect for the text and use IntRect::centered_within()
to sidestep any subpixel jitter. This way it looks good with both bitmap
and vector fonts.
Instead of recomputing the state whenever someone asks for it, we now
cache it when the attribute is added/changed/removed.
Before this change, HTMLElement::is_editable() was 6.5% of CPU time
when furiously resizing Hacker News. After, it's less than 0.5%. :^)
After finishing layout, iframe layout boxes (FrameBox) get notified
about their new size by LayoutState::commit(). This information is
forwarded to the nested browsing context, where it can be used for
layout of the nested document.
The problem here was that we notified the FrameBox twice. Once when
assigning the used offset to its paintable, and once when assigning its
size. Because the offset was assigned first, we ended up telling the
FrameBox "btw, your size is 0x0". This caused us to throw away all
the layout information we had for the nested document.
We'd then say "actually, your size is 300x200" (or something) but by
then it was already too late, and we had to do a full relayout.
This caused iframes to flicker as every time their containing document
was laid out, we'd nuke the iframe layout and redo it (on a zero timer).
The fix is pleasantly simple: we didn't need to inform the nested
document of its offset in the containing document's layout anyway. Only
its size is relevant. So we can simply remove the first call, which
removes the bogus 0x0 temporary size.
Note that iframes may still flicker if they change size in the
containing document. That's a separate issue that will require more
finesse to solve. However, this fixes a very noticeable common case.
Many actions affect Window modality, so let's put a temporary change
governor on activation to stop race conditions.
Fixes being able to spam open/close shortcuts and spawn multiple
FilePickers, among other things.
Creates two new gatekept helpers for FilePicker and MessageBox to be
used by FSAS to replace the "dummy window" approach to centering
Dialogs. There was a slight delay in creating two windows, one a
transparent intermediary hidden behind the second, to display FSAS
Dialogs. Now we only need to make the window we actually see.
These options were created 2 years ago but the only use cases thus far
are for Center and CenterWithinParent, so let's chuck the rest for now.
Adds a new DoNotPosition option to opt out of automatic centering and
a ScreenPosition setter and getter for configuration before exec()
Fixes translating in the wrong direction or not at all in the case of
a constraint at (0,0). This doesn't appear to be used anywhere yet but
is needed in the upcoming patch.
GCC 13 produces the following true positive warnings:
- `-Wredundant-move` when trying to move `result->tooltip()`, which
is a const reference in `Assistant/main.cpp`
- `-Wuse-after-free` when freeing an environment variable before
removing it from `s_malloced_environment_variables`
- `-Wdangling-pointer` when storing an AST node's `this` pointer to the
interpreter's node stack in LibJS. This is not actually an issue, as
it is popped when the scope ends, but GCC has no way of telling this.
It's unnecessary to allocate a string when we only want to compare it
with another string.
This change also adds a helper for string literals, so that we won't
need to add -sv suffix everywhere. :^)
...and instead assume it's BGRx8888 or BGRA8888, for now. Always
treating the target as BGRA8888 leads to the alpha channel being
interpreted incorrectly sometimes (as can be seen with WindowServer
overlays).
Fixes#18749
This allows us to create a PlaybackManager from a file which has already
been mapped, instead of passing a file name.
This means that anyone who uses `PlaybackManager` can now use LibFSAC :)
