Rather than blitting and rendering each window every time, only
render what actually changed. And while doing so, only render
the portions that are visible on the screen. This avoids flickering
because flipping framebuffers isn't always perfectly in sync with
the code, so it's possible that the flip happens slightly delayed
and we can briefly see the next iteration having partially completed.
Also, avoid touching the mouse cursor unless it is in an area that
needs updating. This reduces flickering unless it is over an area
that is updated often. And because we no longer render the entire
screen, we'll save the contents below the cursor so that we can
hide it before touching that area.
Fixes#2981
Inspired by #3047, and my struggles to understand how cmake is supposed to work ^^
Thanks to @bgianfo, who made me realize that ninja can be used just like make.
No idea why I didn't notice that earlier.
...{All} to ParentNode. Exposes createDocumentFragment and
createComment on Document. Stubs out the document.body setter.
Also adds ParentNode back :^).
Instead of translating between the sorting proxy and the underlying
file system model at all the DirectoryView API boundaries, just hand
out indexes into the sorting proxy model.
The only thing those indexes are used for on the outside is to
retrieve a GUI::FileSystemModel::Node for an index, so add a nice
helper on DirectoryView that turns a ModelIndex into a Node&.
The Node API was obnoxiously requiring you to pass the model into it
all the time, simply because nodes could not find their way back to
the containing model. This patch adds a back-reference to the model
and simplifies the API.
This patch begins the process of converting FileManager's desktop mode
to using the DirectoryView class.
This will allow us to share most of the code between the two different
runtime modes of FileManager.
We lose a bit of functionality in this patch, but we'll bring it back!
This requires moving remove_all_children() from ParentNode to
Node, which makes ParentNode.cpp empty, so remove it.
It also co-opts the existing Node::text_content() method and
tweaks it slightly to fit the semantics of Node.textContent.
The optional 2nd and 3rd arguments are not yet implemented.
This assumes that `this` is the Array constructor and doesn't yet
implement the more general behavior in the ES6 spec that allows
transferring this method to other constructors.
I noticed that nothing actually applies the wallpaper on startup.
I wasn't sure where to put the responsibility, so I gave it to
the desktop mode file manager.
Also adds a save_config option to set_wallpaper so it doesn't
needlessly save the config.
Pledges and Veil state don't really make sense for kernel mode
processes, as they can do what ever they want since they are in
kernel mode. Make this clear in the system monitor UI by marking
these entries as null.
