LibWeb keeps growing and the Web namespace is filling up fast.
Let's put DOM stuff into Web::DOM, just like we already started doing
with SVG stuff in Web::SVG.
.. and make travis run it.
I renamed check-license-headers.sh to check-style.sh and expanded it so
that it now also checks for the presence of "#pragma once" in .h files.
It also checks the presence of a (single) blank line above and below the
"#pragma once" line.
I also added "#pragma once" to all the files that need it: even the ones
we are not check.
I also added/removed blank lines in order to make the script not fail.
I also ran clang-format on the files I modified.
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.
For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.
Going forward, all new source files should include a license header.
I though it would be nice to also show the style that the browser uses
to display an element.
In order to do that, in place of the styles table I've put a tab widget,
with tabs for both element and computed element styles.
When selecting an element in the browser's DOM inspector, we now also
show the resolved CSS properties (and their values) for that element.
Since the inspector was growing a bit more complex, I moved it out of
the "show inspector" action callback and into its own class.
In the future, we will probably want to migrate the inspector down to
LibHTML to make it accessible to other clients of the library, but for
now we can keep working on it inside Browser. :^)
