SpiceAgent depends on header files built as part of the Clipboard
target.
|
|
|
|
|
|
Clang throws a fit when it encounters this code, since we already have
the standardized designated initializer syntax in C++20, which we should
use.

|
|
|
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.

(#8515)"
This reverts commit 1c06d772628a0191289fe30edcc143e29ba2ca32.
This was squashed by mistake, the rebased version will follow.

* 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.
|
|
This fixes a couple of warnings emitted by Clang.
|
|
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.
|
|
Since we use C++20, we can move to the new standardized designated
initializer syntax.

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.

You can now put the WindowServer into "flash flush" mode by doing:
$ wsctl -f 1
To disable it, somewhat obviously:
$ wsctl -f 0
|
|
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. :^)

Clean up a FIXME about overly aggressive invalidation.
|
|
|
|
This patch adds the concept of a window being "Pinnable" (always drawn
on top of other windows). This can be toggled through a new checkable
action in the top left corner's window menu.
|
|
|
|
Calling Window::is_modal requires the window to be on a window stack,
so we need to check this before removing it from the window stack.
|
|
|
|
Because window states and various flags can affect the windows'
rendered areas it's safer to use the last computed occlusion rectangles
to invalidate areas on the screen that may have to be re-rendered due
to e.g. a window size change.
Fixes #6723

Depending on the driver, the second buffer may not be located right
after the first, e.g. it may be page aligned. This removes this
assumption and queries the driver for the appropriate offset.
|
|
Some devices may require DMA transfers to flush the updated buffer
areas prior to flipping. For those devices we track the areas that
require flushing prior to the next flip. For devices that do not
support flipping, but require flushing, we'll simply flush after
updating the front buffer.
This also adds a small optimization that skips these steps entirely for
a screen that doesn't have any updates that need to be rendered.

The only remaining sync call from client to server is now the call
that switches a window's backing store. That one actually relies on
the synchronization to hand over ownership of the backing stores,
so it has to stay synchronous for now.
|
|
Use shrink-to-fit instead of manually calculating the widget size.

We should only run the minimize and launch animations for windows that
are actually rendered on the currently visible virtual desktop.
|
|
We should only show/hide the windows on the current virtual desktop.
