The time interval for animations is most often described as `duration`
in animation contexts and the `WindowServer::Animation` class
should reflect that.
The menus always thought they were being outside of the main screen,
which caused them to be left and/or top aligned. This also fixes the
calculation of the available space by using the screen rectangle where
it will be displayed.
We care about showing 'Assistant' app as fast as possible when the
hotkey is pressed. In order to do that, we can parse the `.af` file
ahead of time and have it ready to use.
To make Assistant useful we need a way to quickly trigger it. I've
added a new specialized event coming from the window server for when a
user is holding down 'Super' and hits 'Space'.
The Taskbar will be able to listen for this event and spawn a new
instance of the Assistant if it's not already running.
Since being tiled means we restrict rendering a window to the screen it
is on (so that we don't "bleed" into an adjacent screen), we need to
untile it if the window either can't fit into the screen, or it is
detached from the screen edges.
The launch_origin_rect parameter to create_window() specifies where on
screen the window was launched from. It's optional, but if you provide
it, the new window will have a short wireframe animation from the origin
to the initial window frame rect.
GUI::Window looks for the "__libgui_launch_origin_rect" environment
variable. Put your launch origin rect in there with the format
"<x>,<y>,<width>,<height>" and the first GUI::Window shown by the app
will use that as the launch origin rect.
Also it looks pretty neat, although I'm sure we can improve it. :^)
This patch adds the WindowServer::Animation class, which represents
a simple animation driven by the compositor.
An animation has a length (in milliseconds) and two hooks:
- on_update: called whenever the animation should render something.
- on_stop: called when the animation is finished and/or stopped.
This patch also ports the window minimization animation to this new
mechanism. :^)
We regularily need to flush many rectangles, so instead of making many
expensive ioctl() calls to the framebuffer driver, collect the
rectangles and only make one call. And if we have too many rectangles
then it may be cheaper to just update the entire region, in which case
we simply convert them all into a union and just flush that one
rectangle instead.
This fixes a regression where the geometry label isn't updating even
though the window geometry had changed because the geometry label's
location isn't changing.
An Overlay is similar to a transparent window, but has less overhead
and does not get rendered within the window stack. Basically, the area
that an Overlay occupies forces transparency rendering for any window
underneath, which allows us to render them flicker-free.
This also adds a new API that allows displaying the screen numbers,
e.g. while the user configures the screen layout in DisplaySettings
Because other things like drag&drop or the window-size label are not
yet converted to use this new mechanism, they will be drawn over the
screen-number currently.
My previous PR had a small error in rebasing and removed a line in
open_file_url. This caused opening text files from the terminal to
always open with an empty TextEditor.
This commit fixes that problem!
This commit gets rid of hard coded file handlers in Launcher.cpp in
favor of using values in the LaunchServer.ini config file.
The previous commit adds checks for the existence of handler programs
while registering handlers. This commit takes advantage of that and
ensures that LaunchServer will not attempt to open a file with a
nonexistent program and can properly report failure before spawning a
new child process.
Resolves#8120
This adds checks in load_handlers() and load_config() to see if the
programs specified in the config files exist before registering them as
handlers.
Resolves#8121
If a window which has an active modal window is focused, the modal
window starts blinking. In this case, the window (and modal) should
still be focused. For this, the order of the checks in
process_mouse_event_for_window has to be changed.
This fixes#8183.
Since MultiScaleBitmaps only loads icons for the scales in use, we need
to unconditionally reload them so that we pick up the correct bitmaps
for a scale that hasn't been previously used.
This enables the shot utility to capture all screens or just one, and
enables the Magnifier application to track the mouse cursor across
multiple screens.
This enables rendering of mixed-scale screen layouts with e.g. high
resolution cursors and window button icons on high-dpi screens while
using lower resolution bitmaps on regular screens.
This sets the stage so that DisplaySettings can configure the screen
layout and set various screen resolutions in one go. It also allows
for an easy "atomic" revert of the previous settings.
If there are any screens that are detached from other screens it would
not be possible to get to them using the mouse pointer. Also make sure
that none of the screens are overlapping.
We were calculating the old window rectangle after changing window
states that may affect these calculations, which sometimes resulted
in artifacts left on the screen, particularily when tiling a window
as this now also constrains rendering to one screen.
Instead, just calculate the new rectangle and use the window's
occlusion information to figure out what areas need to be invalidated.
When a window is maximized or tiled then we want to constrain rendering
that window to the screen it's on. This prevents "bleeding" of the
window frame and shadow onto the adjacent screen(s).
This allows WindowServer to use multiple framebuffer devices and
compose the desktop with any arbitrary layout. Currently, it is assumed
that it is configured contiguous and non-overlapping, but this should
eventually be enforced.
To make rendering efficient, each window now also tracks on which
screens it needs to be rendered. This way we don't have to iterate all
the windows for each screen but instead use the same rendering loop and
then only render to the screen (or screens) that the window actually
uses.
PR #5665 updated TextEditor to open files at a specific line/column
location using the file:line:col argument, rather than the -l flag.
This change updates LaunchServer to use that convention, though note it
does only pass the line number and not a column number, as per all
previous behaviour.
Some paths of the mouse event processing code will upgrade the event
from a regular MouseDown to a MouseDoubleClick. That's why we were
passing `MouseEvent&` everywhere.
For the paths that don't need to do this, passing `MouseEvent const&`
reduces the cognitive burden a bit, so let's do that.
