When hovering over a C++ token that we have a man page for, we now show
the man page in a tooltip window.
This feels rather bulky at the moment, but the basic mechanism is quite
neat and just needs a bunch of tuning.
In order for this to work nicely, I made the line box classes use float
instead of int for its geometry information.
Justification works by distributing all of the whitespace on the line
(including the trailing whitespace before the line break) evenly across
the spaces in-between words.
We should probably use floating point (or maybe fixed point?) for all
the layout metrics stuff. But one thing at a time. :^)
This patch implements basic support for <a href="#foo"> fragment links.
To figure out where we actually want to scroll to, we have to do
something different based on the layout node's box type. So if it's a
regular LayoutBox we can just use the LayoutBox::position().
However, if it's an inline layout node, we use the position of the
first line box fragment in the containing block contributed by this
layout node or one of its descendants.
It's now possible to set a page background image via <body background>.
Also, HtmlView now officially handles rendering the body element's
background (color, image or both.) LayoutBox is responsible for all
other background rendering.
Note that it's not yet possible to use CSS background-image properties
directly, since we can't parse them yet. :^)
This is currently very aggressive. Whenever the Document's hovered node
changes, we invalidate all style and do a full relayout.
It does look cool though. So cool that I'm adding it to the default
stylesheet. :^)
This patch adds the CharacterData subclass of Node, which is now the
parent class of Text and a new Comment class.
A Comment node is one of these in HTML: <!--hello friends-->
Since these occur somewhat frequently on the web, we need to be able
to parse them.
This patch also adds a child rejection mechanism to the DOM tree.
Nodes can now override is_child_allowed(Node) and return false if they
don't want a particular Node to become a child of theirs. This is used
to prevent Document from taking on unwanted children.
The <br> element will produce a special LayoutBreak node in the layout
tree, which forces a break in the line layout whenever encountered.
This patch also makes LayoutBlock use the current line-height as the
minimum effective height for each line box. This ensures that having
multiple <br> elements in a row doesn't create 0-height line boxes.
Just in time for Serenity's 1st birthday, here is the <blink> element!
This patch adds a bunch of different mechanisms to enable partial
repaints of the layout tree (LayoutNode::set_needs_display()))
It also adds LayoutNode::is_visible(), which can be toggled to prevent
a LayoutNode from rendering anything (it still takes up space though.)
This patch adds basic support for external stylesheets. It currently
only works with file:// URLs.
We do a synchronous full relayout after loading a stylesheet, which is
definitely on the aggressive side, but it gives us something to work
on improving. :^)
This patch adds the 17 color names from CSS2.1, as well as support for
the "#rgb" shorthand where each component is a hex digit that gets
multiplied by 17.
This patch implements two more selector features:
- "div + p" matches the <p> sibling immediately after a <div>.
- "div ~ p" matches all <p> siblings after a <div>.
GFilePicker
- Fixed GFilePicker to use new ref-counted construct method to stop crashing on open dialog.
- PaintBrush is still crashing on open dialog due to an unrelated issue.
PaintBrush
- Created 16x16 icon for PaintBrush
- Moved Open option into App menu.
- Changed help menu to make use of the standardized About dialog.
Booting without a wallpaper is significantly faster in QEMU when the
host machine is under load (e.g while recording the screen..)
Using a wallpaper is now optional. :^)
