When changing the theme, there were two Core::ConfigFile instances
(one class scoped -- m_config and one function scoped -- wm_config)
fighting over the file, resulting in not saving the new theme name
to the config. :^(
This makes WindowServer remember selected theme from the menu
after reboot!
If a screen layout cannot be applied, instead of failing to start
WindowServer try to fall back to an auto-generated screen layout with
the devices that are detected.
Also, be a bit smarter about changing the current screen layout.
Instead of closing all framebuffers and bringing them back up, keep
what we can and only change resolution on those that we need to change
them on. To make this work we also need to move away from using an
array of structures to hold compositor related per-screen data to
attaching it to the Screen itself, which makes re-using a screen much
simpler.
This feels a bit awkward right now, and needs code duplication - I think
adding a mechanism to the AppFile class to run the executable would be
neat, especially if we add an arguments field to app files - but this
will do for now.
We only need to re-draw the item being selected and the item being
deselected. We also don't care anymore if applets were added or
removed as we no longer have a global menu bar.
We were re-rendering areas that were considered transparency areas even
though they weren't transparency areas or were occluded by opaque
areas.
In order to fix this, we need to be a bit smarter about what is above
and below any given window. Even though a window may have transparent
areas, if those are occluded by opaque window areas on top they are
not actually any areas that should be rendered at all. And the opposite
also applies, opaque window areas for windows below that are occluded
by transparent areas, do need to be rendered as transparency. This
solves the problem of unnecessary transparency areas.
The other problem is that we need to know what areas of a window's
dirty rectangles affect other windows, and where. Basically any
opaque area that is somehow below a transparent area that isn't
otherwise occluded, and any transparent area above any other window
area (transparent or opaque) needs to be marked dirty prior to
composing. This makes sure that all affected windows render these
areas in the correct order. To track these, we now have a map of
affected windows and the rectangles that are affected (because not all
of that window's transparency areas may be affected).
This implements window stealing in WindowServer, which allows clients
to mark a window they own as 'stealable' by another client. Indicating
that the other client may use it for any purpose.
This also updates set_window_parent_from_id so that the client must
first mark its window as stealable before allowing other clients to
use it as a parent.
This transitions from synchronous IPC calls to asynchronous IPC calls
provided through a synchronous interface in LibFileSystemAccessClient
which allows the parent Application to stay responsive.
It achieves this with Promise which is pumping the Application event
loop while waiting for the Dialog to respond with the user's action.
LibFileSystemAccessClient provides a lazy singleton which also ensures
that FileSystemAccessServer is running in the event of a crash.
This also transitions TextEditor into using LibFileSystemAccessClient.
A SPICE agent communicates with the host OS to provide nifty features
like clipboard sharing :^)
This patch implements only plain-text clipboard sharing.

If a user picks a file which can't be opened for some reason, we should
still return the value, so client applications can report the error
along with the chosen filepath.
If the device requires a flush and we modify the front buffer, we need
to flush those changes to the front buffer. This makes the flashing
work using the VirtIOGPU.
Also fix a minor bug where we flushed the front buffer instead of
the back buffer after flipping, which caused the VirtIOGPU to not work
as expected when using the SDL backend and disabling buffer flipping.
Adds new service FileSystemAccessServer which allows programs to
request a file descriptor for any file on the file system.
The user can be prompted to choose the path with a FilePicker, or the
path can be provided by the application which will show a MessageBox
showing the pid and name of the calling process and allows the user to
approve or deny the request.
The windows in the background are ignored when the window is fullscreen.
However, we still would like to see the background if that window is
transparent.
* LibGUI: Verify m_window_id is not-zero in set_maximized
Window::set_maximized requires non-zero window id to be a valid call,
i.e. calling Window::show beforehand. A verify statement before the
server call can help developers by hinting correct usage.
* LibGUI: Paint background when the fullscreen window is transparent
The windows in the background are ignored when the window is fullscreen.
However, we still would like to see the background if that window is
transparent.
* Userland: Add ability to capture rectangular region in shot
A click and drag selectable, transparent, fullscreen window is
displayed with the command line argument -r for screenshots.
This makes it easy for the user to just throw the mouse at the corner
of the screen and obtain the desired outcome (eg. opening the start
menu), without having to precisely position the cursor over one of the
buttons.
This patch adds a missing minimize check for highligted windows in
WindowStack::for_each_visible_window_of_type_from_front_to_back().
Minimized windows should not be treated as visible in this context.
Previously, iterating through each visible Window when recomputing
occlusions in the Compositor would cause a crash if a highlighted
Window is also minimized at the same time. As the WindowSwitcher
currently highligts Windows even when they are minimized, opening
it while any Window is minimized would cause WindowServer to crash.
This patch removes the background behind window icons
in the WindowSwitcher which looked like it was being
rendered incorrectly (without alpha) previously.
This patch introduces the SQLServer system server. This service is
supposed to be the only process/application talking to database storage.
This makes things like locking and caching more reliable, easier to
implement, and more efficient.
In LibSQL we added a client component that does the ugly IPC nitty-
gritty for you. All that's needed is setting a number of event handler
lambdas and you can connect to databases and execute statements on them.
Applications that wish to use this SQLClient class obviously need to
link LibSQL and LibIPC.
GCC likely has a builtin intrinsic that evaluates the operation at
compile-time, even if the `LibM` is not declared as constexpr. Clang,
however, does not like it, and it failed to compile this code.
We already do this in most places, so the style should be consistent.
Also, Clang does not like it, as this could cause an unexpected compile
error if some statements are added to the default label or a new label
is added above it.
While structs being forward declared as classes is not strictly an
issue, Clang complains as this is not portable code, since some ABIs
treat classes declared as `class` and `struct` differently.
It's easier to fix these than to reason about explicitly disabling
another warning.
It might be the case that we are passing non-movable/non-copyable things
through IPC. In this case, Clang will emit a warning as it can't
generate the requested default move/copy ctor for the IPC message.
To fix this, we use a `#pragma` to make the compiler silently ignore our
request.
The same was the case with the three-way comparison in `Screen`. Since
we don't use the three-way comparison operator anywhere else in our
codebase, we simply use the `==` operator instead.
This fixes a bug with menu keyboard navigation. If you pressed the right
arrow to enter a submenu, then the left arrow to exit the submenu, then
right and left again it would leave no menu item selected.
Because descending into the submenu wasn't making it the current menu,
when you press the left arrow it couldn't find the "current menu" in the
stack, so didn't know what menu to pop back to.
It was an accident that it worked the first time you navigated into the
menu. Selecting the parent item also opened the submenu, and opening
an already open menu sets it as the current menu. After closing the
submenu with the left arrow, it is no longer already open, so it wasn't
getting set as the current menu.
Before this change, invalidating any rect in a WindowFrame would cause
the entire window (including frame & drop shadow) to get invalidated,
leading to copious amounts of overdraw when mousing over menubars,
titlebars, and window buttons.
We now simply allow the partial frame invalidations through to the
window's dirty rects collection and the compositor takes care of it.
ec6debb changed item_index_at to return -1 when hovering over a
separator. The intent was to not send the separator to clients for
MenuItemEntered.
However, this had the unintented consequence of not closing the submenu
when you hover over a separator. Submenus ignore when the item index is
-1 in order to leave the menu open when you move the mouse outside. This
ends up leaving the submenu open without the highlight to show what menu
item the submenu belongs to.
A slightly less severe consequence is that pressing the up or down arrow
key in such a situation would now go the top or bottom of the menu
rather than the item above or below the separator.
We now push the special casing of separators into set_hovered_index so
that the rest of the code behaves as it did before ec6debb.
Previously, this mode would flash flush/repaint rects in yellow for
however it long it took for the compositor to replace the yellow with
the final image instead.
Now we usleep() for 10 ms when flashing, so you get a chance to see
the yellow. This immediately makes "flash flush" mode super useful. :^)
