Color themes are loaded from .ini files in /res/themes/
The theme can be switched from the "Themes" section in the system menu.
The basic mechanism is that WindowServer broadcasts a SharedBuffer with
all of the color values of the current theme. Clients receive this with
the response to their initial WindowServer::Greet handshake.
When the theme is changed, WindowServer tells everyone by sending out
an UpdateSystemTheme message with a new SharedBuffer to use.
This does feel somewhat bloated somehow, but I'm sure we can iterate on
it over time and improve things.
To get one of the theme colors, use the Color(SystemColor) constructor:
painter.fill_rect(rect, SystemColor::HoverHighlight);
Some things don't work 100% right without a reboot. Specifically, when
constructing a GWidget, it will set its own background and foreground
colors based on the current SystemColor::Window and SystemColor::Text.
The widget is then stuck with these values, and they don't update on
system theme change, only on app restart.
All in all though, this is pretty cool. Merry Christmas! :^)

Windows that are being moved around by the user are now called "moving"
windows instead of "dragging" windows, to avoid confusion with the
drag and drop stuff.

This is a tiny bar at the left of the taskbar where you can put
your most used apps to launch them with a single click. In a way,
it's another replacement for the Launcher, in addition to the app
menu. Unlike the launcher and the menu, it's not meant to be the
primary way to launch apps; it's only a faster way to launch a few
most often used utilities.

This patch adds "submit" inputs and default (text box) inputs, as well
as form elements that can be submitted.
Layout of input elements is implemented via a new LayoutWidget class
that allows you to put an arbitrary GWidget in the layout tree.
At the moment, the DOM node sets the initial size of the LayoutWidget,
and then the positioning is done by the normal layout algorithm.
We also now support submitting a <form method="GET">, which does a full
replacing load with a URL based on the form's action + a query string
built from the name/value of input elements within the submitted form.
This is pretty neat! :^)

Getting these to work will take a lot of work, but most of it will be
pretty fun, so I guess we start by importing them. :^)
|
|
The borders still look very wrong with any border-width other than 1,
but at least we can see that they have the right color, and end up in
mostly the right place :^)
|
|
A selector like "[foo]" is now parsed as a universal selector component
with an attribute match type. Pretty neat :^)
|
|
This patch adds a[foo] and a[foo=bar] attribute selectors.
Note that an attribute selector is an optional part of a selector
component, and not a component on its own.

The Launcher's functionality has been replaced by the app shortcuts in
the system menu.
There were various window management hacks to ensure that the launcher
stayed below all other windows while also being movable, etc.

I'll be reconstructing parts of the VisualBuilder application here and
then we can retire VisualBuilder entirely once all the functionality
is available in HackStudio.

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.

Ctrl+R will now execute "make run" in the project directory. :^)
|
|
Also import a little default C++ project called "little" :^)

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 really just "center { display: block; text-align: center; }" in
the default stylesheet, but it totally works!
|
|
This was easier than I imagined; we just shift each line box to the
left based on the alignment and the remaining space on each line. :^)
|
|
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. :^)

Turn consume_whitespace() into consume_whitespace_or_comments() and
have it swallow /* comments */ as well.
|
|
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.)
|
|
We now support loading both file:// and http:// URLs. Feel free to
visit http://www.serenityos.org/ and enjoy the fancy good times. :^)
|
|
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>.
|
|
|
|
The CSS engine now correctly matches selectors like "#foo #bar #baz".
|
|
|

It was conflicting with the html program and I'm too lazy to deal with
that right now. :^)
|
|
Also add a simple test page for inline style sheets.
|
|
|
|
This will be useful for testing rendering, hit testing, etc.
|
|
This is a more appropriate name now that it does a lot
more than just manage processes ^)
|
|
The following apps get new icons:
- IRCClient
- ProcessManager
- Snake
- Terminal
- TextEditor
...and the PaintBrush icon has its saturation increased a bit.
Also remove FontEditor from the Launcher default settings since it
doesn't really belong in the set of commonly used apps.
