From 4a829498540d41a19da61f794dd82deac0b1c15e Mon Sep 17 00:00:00 2001 From: outfoxxed Date: Sat, 24 Feb 2024 02:06:40 -0800 Subject: [PATCH] feat(wayland): custom layershell implementation A fair amount of things are broken but not in the layershell interface itself. The shell window platform extensions are next in line for refactoring and relevent issues will be fixed then. Same for docs. --- .clang-format | 6 +- CMakeLists.txt | 2 - Justfile | 2 +- src/core/CMakeLists.txt | 11 +- src/core/layershell.cpp | 300 ------------- src/core/main.cpp | 8 - src/core/proxywindow.hpp | 6 +- src/core/qmlscreen.cpp | 5 +- src/core/reload.hpp | 4 +- src/core/rootwrapper.cpp | 6 +- src/core/shellwindow.hpp | 21 + src/wayland/CMakeLists.txt | 9 +- src/wayland/layer_surface.cpp | 165 +++++++ src/wayland/layer_surface.hpp | 48 +++ src/wayland/layershell.cpp | 145 +++++++ src/wayland/layershell.hpp | 122 ++++++ src/wayland/shell_integration.cpp | 22 + src/wayland/shell_integration.hpp | 21 + src/wayland/waylandshellwindow.cpp | 174 ++++++++ .../waylandshellwindow.hpp} | 84 +--- .../wl-proto/wlr-layer-shell-unstable-v1.xml | 407 ++++++++++++++++++ 21 files changed, 1167 insertions(+), 401 deletions(-) delete mode 100644 src/core/layershell.cpp create mode 100644 src/wayland/layer_surface.cpp create mode 100644 src/wayland/layer_surface.hpp create mode 100644 src/wayland/layershell.cpp create mode 100644 src/wayland/layershell.hpp create mode 100644 src/wayland/shell_integration.cpp create mode 100644 src/wayland/shell_integration.hpp create mode 100644 src/wayland/waylandshellwindow.cpp rename src/{core/layershell.hpp => wayland/waylandshellwindow.hpp} (55%) create mode 100644 src/wayland/wl-proto/wlr-layer-shell-unstable-v1.xml diff --git a/.clang-format b/.clang-format index eb81a3b..610ee65 100644 --- a/.clang-format +++ b/.clang-format @@ -31,12 +31,12 @@ SpaceBeforeInheritanceColon: false SpaceBeforeParens: ControlStatementsExceptControlMacros SortIncludes: CaseSensitive PointerAlignment: Left -PackConstructorInitializers: NextLine +PackConstructorInitializers: CurrentLine LineEnding: LF InsertBraces: false -BreakConstructorInitializers: AfterColon +BreakConstructorInitializers: BeforeComma BreakBeforeBraces: Custom -BreakInheritanceList: AfterColon +BreakInheritanceList: BeforeComma AllowAllParametersOfDeclarationOnNextLine: false AllowAllArgumentsOnNextLine: false AlwaysBreakTemplateDeclarations: Yes diff --git a/CMakeLists.txt b/CMakeLists.txt index 29b4413..4902a83 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -5,8 +5,6 @@ set(QT_MIN_VERSION "6.6.0") set(CMAKE_CXX_STANDARD 20) set(CMAKE_CXX_STANDARD_REQUIRED ON) -option(LAYERSHELL "Enable wayland layershell support" ON) - option(WAYLAND "Enable wayland support" ON) add_compile_options(-Wall -Wextra) diff --git a/Justfile b/Justfile index c4ffa6e..687f266 100644 --- a/Justfile +++ b/Justfile @@ -30,4 +30,4 @@ clean: rm -rf {{builddir}} run *ARGS='': build - {{builddir}}/quickshell {{ARGS}} + {{builddir}}/src/core/quickshell {{ARGS}} diff --git a/src/core/CMakeLists.txt b/src/core/CMakeLists.txt index 54b9fe2..d19c796 100644 --- a/src/core/CMakeLists.txt +++ b/src/core/CMakeLists.txt @@ -16,13 +16,4 @@ qt_add_executable(quickshell qt_add_qml_module(quickshell URI QuickShell) -target_link_libraries(quickshell PRIVATE ${QT_DEPS} quickshell-wayland) - -if (LAYERSHELL) - find_package(LayerShellQt REQUIRED) - - target_link_libraries(quickshell PRIVATE LayerShellQtInterface) - target_compile_definitions(quickshell PRIVATE CONF_LAYERSHELL) - - target_sources(quickshell PRIVATE layershell.cpp) -endif() +target_link_libraries(quickshell PRIVATE ${QT_DEPS} quickshell-waylandplugin) diff --git a/src/core/layershell.cpp b/src/core/layershell.cpp deleted file mode 100644 index 0503906..0000000 --- a/src/core/layershell.cpp +++ /dev/null @@ -1,300 +0,0 @@ -#include "layershell.hpp" - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include "proxywindow.hpp" -#include "shellwindow.hpp" - -WaylandShellWindow::WaylandShellWindow(QObject* parent): - ProxyShellWindow(parent), mWayland(new WaylandShellWindowExtensions(this)) {} - -void WaylandShellWindow::setupWindow() { - this->shellWindow = LayerShellQt::Window::get(this->window);

The layer_surface + returns to the state it had right after layer_shell.get_layer_surface. + The client can re-map the surface by performing a commit without any + buffer attached, waiting for a configure event and handling it as usual. + + + + + Sets the size of the surface in surface-local coordinates. The + compositor will display the surface centered with respect to its + anchors. + + If you pass 0 for either value, the compositor will assign it and + inform you of the assignment in the configure event. You must set your + anchor to opposite edges in the dimensions you omit; not doing so is a + protocol error. Both values are 0 by default. + + Size is double-buffered, see wl_surface.commit. + + + + + + + + Requests that the compositor anchor the surface to the specified edges + and corners. If two orthogonal edges are specified (e.g. 'top' and + 'left'), then the anchor point will be the intersection of the edges + (e.g. the top left corner of the output); otherwise the anchor point + will be centered on that edge, or in the center if none is specified. + + Anchor is double-buffered, see wl_surface.commit. + + + + + + + Requests that the compositor avoids occluding an area with other + surfaces. The compositor's use of this information is + implementation-dependent - do not assume that this region will not + actually be occluded. + + A positive value is only meaningful if the surface is anchored to one + edge or an edge and both perpendicular edges. If the surface is not + anchored, anchored to only two perpendicular edges (a corner), anchored + to only two parallel edges or anchored to all edges, a positive value + will be treated the same as zero. + + A positive zone is the distance from the edge in surface-local + coordinates to consider exclusive. + + Surfaces that do not wish to have an exclusive zone may instead specify + how they should interact with surfaces that do. If set to zero, the + surface indicates that it would like to be moved to avoid occluding + surfaces with a positive exclusive zone. If set to -1, the surface + indicates that it would not like to be moved to accommodate for other + surfaces, and the compositor should extend it all the way to the edges + it is anchored to. + + For example, a panel might set its exclusive zone to 10, so that + maximized shell surfaces are not shown on top of it. A notification + might set its exclusive zone to 0, so that it is moved to avoid + occluding the panel, but shell surfaces are shown underneath it. A + wallpaper or lock screen might set their exclusive zone to -1, so that + they stretch below or over the panel. + + The default value is 0. + + Exclusive zone is double-buffered, see wl_surface.commit. + + + + + + + Requests that the surface be placed some distance away from the anchor + point on the output, in surface-local coordinates. Setting this value + for edges you are not anchored to has no effect. + + The exclusive zone includes the margin. + + Margin is double-buffered, see wl_surface.commit. + + + + + + + + + + Types of keyboard interaction possible for layer shell surfaces. The + rationale for this is twofold: (1) some applications are not interested + in keyboard events and not allowing them to be focused can improve the + desktop experience; (2) some applications will want to take exclusive + keyboard focus. + + + + + This value indicates that this surface is not interested in keyboard + events and the compositor should never assign it the keyboard focus. + + This is the default value, set for newly created layer shell surfaces. + + This is useful for e.g. desktop widgets that display information or + only have interaction with non-keyboard input devices. + + + + + Request exclusive keyboard focus if this surface is above the shell surface layer. + + For the top and overlay layers, the seat will always give + exclusive keyboard focus to the top-most layer which has keyboard + interactivity set to exclusive. If this layer contains multiple + surfaces with keyboard interactivity set to exclusive, the compositor + determines the one receiving keyboard events in an implementation- + defined manner. In this case, no guarantee is made when this surface + will receive keyboard focus (if ever). + + For the bottom and background layers, the compositor is allowed to use + normal focus semantics. + + This setting is mainly intended for applications that need to ensure + they receive all keyboard events, such as a lock screen or a password + prompt. + + + + + This requests the compositor to allow this surface to be focused and + unfocused by the user in an implementation-defined manner. The user + should be able to unfocus this surface even regardless of the layer + it is on. + + Typically, the compositor will want to use its normal mechanism to + manage keyboard focus between layer shell surfaces with this setting + and regular toplevels on the desktop layer (e.g. click to focus). + Nevertheless, it is possible for a compositor to require a special + interaction to focus or unfocus layer shell surfaces (e.g. requiring + a click even if focus follows the mouse normally, or providing a + keybinding to switch focus between layers). + + This setting is mainly intended for desktop shell components (e.g. + panels) that allow keyboard interaction. Using this option can allow + implementing a desktop shell that can be fully usable without the + mouse. + + + + + + + Set how keyboard events are delivered to this surface. By default, + layer shell surfaces do not receive keyboard events; this request can + be used to change this. + + This setting is inherited by child surfaces set by the get_popup + request. + + Layer surfaces receive pointer, touch, and tablet events normally. If + you do not want to receive them, set the input region on your surface + to an empty region. + + Keyboard interactivity is double-buffered, see wl_surface.commit. + + + + + + + This assigns an xdg_popup's parent to this layer_surface. This popup + should have been created via xdg_surface::get_popup with the parent set + to NULL, and this request must be invoked before committing the popup's + initial state. + + See the documentation of xdg_popup for more details about what an + xdg_popup is and how it is used. + + + + + + + When a configure event is received, if a client commits the + surface in response to the configure event, then the client + must make an ack_configure request sometime before the commit + request, passing along the serial of the configure event. + + If the client receives multiple configure events before it + can respond to one, it only has to ack the last configure event. + + A client is not required to commit immediately after sending + an ack_configure request - it may even ack_configure several times + before its next surface commit. + + A client may send multiple ack_configure requests before committing, but + only the last request sent before a commit indicates which configure + event the client really is responding to. + + + + + + + This request destroys the layer surface. + + + + + + The configure event asks the client to resize its surface. + + Clients should arrange their surface for the new states, and then send + an ack_configure request with the serial sent in this configure event at + some point before committing the new surface. + + The client is free to dismiss all but the last configure event it + received. + + The width and height arguments specify the size of the window in + surface-local coordinates. + + The size is a hint, in the sense that the client is free to ignore it if + it doesn't resize, pick a smaller size (to satisfy aspect ratio or + resize in steps of NxM pixels). If the client picks a smaller size and + is anchored to two opposite anchors (e.g. 'top' and 'bottom'), the + surface will be centered on this axis. + + If the width or height arguments are zero, it means the client should + decide its own window dimension. + + + + + + + + + The closed event is sent by the compositor when the surface will no + longer be shown. The output may have been destroyed or the user may + have asked for it to be removed. Further changes to the surface will be + ignored. The client should destroy the resource after receiving this + event, and create a new surface if they so choose. + + + + + + + + + + + + + + + + + + + + + + + Change the layer that the surface is rendered on. + + Layer is double-buffered, see wl_surface.commit. + + + + + + + + + Requests an edge for the exclusive zone to apply. The exclusive + edge will be automatically deduced from anchor points when possible, + but when the surface is anchored to a corner, it will be necessary + to set it explicitly to disambiguate, as it is not possible to deduce + which one of the two corner edges should be used. + + The edge must be one the surface is anchored to, otherwise the + invalid_exclusive_edge protocol error will be raised. + + + + +
