Port the WebContent service to the new MultiInstance mechanism that
Sergey added. This means that every new WebContentView gets its very
own segregated WebContent process.
After layout, we may want to repaint the page, so we now listen for the
PageClient::page_did_invalidate() notification and use it to drive a
client-side repaint.
Note that an invalidation request from LibWeb makes a full roundtrip
to the WebContent client and back since the client drives painting.
The "WebContent" service provides a very restricted instance of LibWeb
running as an unprivileged user account. This will be used to implement
process separation in Browser, among other things.
This first cut of the service only spawns a single WebContent process
when someone connects to /tmp/portal/webcontent. We will soon switch
this over to spawning a new process for each connection.
Since this feature is very immature, we'll be bringing it up inside of
Demos/WebView as a separate demo program. Eventually this will become
a reusable widget that anyone can embed and easily get out-of-process
web content in their GUI.
This is pretty, pretty cool! :^)
.. 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.
I noticed these when playing with the demo locally:
- Use RGB32 instead of RGBA32 for the bitmap buffer. This avoids some
flickering that would sometimes occur.
- Clip the gradient fill to the widget rect rather than the painter
clip rect. In practice, the painter was always clipped to the widget
rect here, but it seems logical to say "fill widget with gradient."
This was a missing feature in the PT_TRACEME command.
This feature allows the tracer to interact with the tracee before the
tracee has started executing its program.
It will be useful for automatically inserting a breakpoint at a
debugged program's entry point.
Since the returned object is now owned by the callee object, we can
simply vend a ChildType&. This allows us to use "." instead of "->"
at the call site, which is quite nice. :^)
This patch adds two new API's:
- WidgetType& GUI::Window::set_main_widget<WidgetType>();
This creates a new main widget for a window, assigns it, and returns
it to you as a WidgetType&.
- LayoutType& GUI::Widget::set_layout<LayoutType>();
Same basic idea, creates a new layout, assigns it, and returns it to
you as a LayoutType&.
If a directory is renamed or deleted before 'make clean', git will
delete the Makefile but leave all of the object and dependency files
around. When make would try to recurse into that directory from the
wildcard, it would error out since there is no Makefile.
This was only used by HashTable::dump() which I used when doing the
first HashTable implementation. Removing this allows us to also remove
most includes of <AK/kstdio.h>.
