As touchpad touches are generally fully abstracted, a client cannot currently know when a user is interacting with the touchpad without moving. This is solved by hold gestures. Hold gestures are notifications about one or more fingers being held down on the touchpad without significant movement. Hold gestures are primarily designed for two interactions: - Hold to interact: where a hold gesture is active for some time a menu could pop up, some object could be selected, etc. - Hold to cancel: where e.g. kinetic scrolling is currently active, the start of a hold gesture can be used to stop the scroll. Unlike swipe and pinch, hold gestures, by definition, do not have movement, so there is no need for an "update" stage in the gesture. Create two structs, wlr_event_pointer_hold_begin and wlr_event_pointer_hold_end, to represent hold gesture events and the signals to emit them: wlr_pointer->pointer.hold_begin/hold_end. |

wlroots
Pluggable, composable, unopinionated modules for building a Wayland compositor; or about 50,000 lines of code you were going to write anyway.
- wlroots provides backends that abstract the underlying display and input hardware, including KMS/DRM, libinput, Wayland, X11, and headless backends, plus any custom backends you choose to write, which can all be created or destroyed at runtime and used in concert with each other.
- wlroots provides unopinionated, mostly standalone implementations of many Wayland interfaces, both from wayland.xml and various protocol extensions. We also promote the standardization of portable extensions across many compositors.
- wlroots provides several powerful, standalone, and optional tools that implement components common to many compositors, such as the arrangement of outputs in physical space.
- wlroots provides an Xwayland abstraction that allows you to have excellent Xwayland support without worrying about writing your own X11 window manager on top of writing your compositor.
- wlroots provides a renderer abstraction that simple compositors can use to avoid writing GL code directly, but which steps out of the way when your needs demand custom rendering code.
wlroots implements a huge variety of Wayland compositor features and implements them right, so you can focus on the features that make your compositor unique. By using wlroots, you get high performance, excellent hardware compatibility, broad support for many wayland interfaces, and comfortable development tools - or any subset of these features you like, because all of them work independently of one another and freely compose with anything you want to implement yourself.
Check out our wiki to get started with wlroots. Join our IRC channel: #sway-devel on Libera Chat.
wlroots is developed under the direction of the sway project. A variety of wrapper libraries are available for using it with your favorite programming language.
Building
Install dependencies:
- meson
- wayland
- wayland-protocols
- EGL
- GLESv2
- libdrm
- GBM
- libinput
- xkbcommon
- udev
