Events that the embedder sends to Servo, including events from the windowing system.

Variants

Idle

Sent when no message has arrived, but the event loop was kicked for some reason (perhaps by another Servo subsystem).

FIXME(pcwalton): This is kind of ugly and may not work well with multiprocess Servo. It’s possible that this should be something like CompositorMessageWindowEvent(compositor_thread::Msg) instead.

Refresh

Sent when part of the window is marked dirty and needs to be redrawn. Before sending this message, the window must make the same GL context as in PrepareRenderingEvent current.

WindowResize

Sent when the window is resized.

AllowNavigationResponse(PipelineId, bool)

Sent when a navigation request from script is allowed/refused.

LoadUrl(TopLevelBrowsingContextId, ServoUrl)

Sent when a new URL is to be loaded.

MouseWindowEventClass(MouseWindowEvent)

Sent when a mouse hit test is to be performed.

MouseWindowMoveEventClass(DevicePoint)

Sent when a mouse move.

Touch(TouchEventType, TouchId, DevicePoint)

Touch event: type, identifier, point

Wheel(WheelDelta, DevicePoint)

Sent when user moves the mouse wheel.

Scroll(ScrollLocation, DeviceIntPoint, TouchEventType)

Sent when the user scrolls. The first point is the delta and the second point is the origin.

Zoom(f32)

Sent when the user zooms.

PinchZoom(f32)

Simulated “pinch zoom” gesture for non-touch platforms (e.g. ctrl-scrollwheel).

ResetZoom

Sent when the user resets zoom to default.

Navigation(TopLevelBrowsingContextId, TraversalDirection)

Sent when the user uses chrome navigation (i.e. backspace or shift-backspace).

Quit

Sent when the user quits the application

ExitFullScreen(TopLevelBrowsingContextId)

Sent when the user exits from fullscreen mode

Keyboard(KeyboardEvent)

Sent when a key input state changes

IMEComposition(CompositionEvent)

Sent for IME composition updates

Reload(TopLevelBrowsingContextId)

Sent when Ctr+R/Apple+R is called to reload the current page.

NewWebView(ServoUrl, TopLevelBrowsingContextId)

Create a new top-level browsing context.

CloseWebView(TopLevelBrowsingContextId)

Close a top-level browsing context.

SendError(Option<TopLevelBrowsingContextId>, String)

Panic a top-level browsing context.

MoveResizeWebView(TopLevelBrowsingContextId, DeviceRect)

Move and/or resize a webview to the given rect.

ShowWebView(TopLevelBrowsingContextId, bool)

Start painting a webview, and optionally stop painting all others.

HideWebView(TopLevelBrowsingContextId)

Stop painting a webview.

RaiseWebViewToTop(TopLevelBrowsingContextId, bool)

Start painting a webview on top of all others, and optionally stop painting all others.

FocusWebView(TopLevelBrowsingContextId)

Make a webview focused.

BlurWebView

Make none of the webviews focused.

ToggleWebRenderDebug(WebRenderDebugOption)

Toggles a debug flag in WebRender

CaptureWebRender

Capture current WebRender

ClearCache

Clear the network cache.

ToggleSamplingProfiler(Duration, Duration)

Toggle sampling profiler with the given sampling rate and max duration.

MediaSessionAction(MediaSessionActionType)

Sent when the user triggers a media action through the UA exposed media UI (play, pause, seek, etc.).

SetWebViewThrottled(TopLevelBrowsingContextId, bool)

Set whether to use less resources, by stopping animations and running timers at a heavily limited rate.

IMEDismissed

Virtual keyboard was dismissed

InvalidateNativeSurface

Sent on platforms like Android where the native widget surface can be automatically destroyed by the system, for example when the app is sent to background.

ReplaceNativeSurface(*mut c_void, DeviceIntSize)

Sent on platforms like Android where system recreates a new surface for the native widget when it is brough back to foreground. This event carries the pointer to the native widget and its new size.

Gamepad(GamepadEvent)

Sent when new Gamepad information is available.

Vsync

Vertical Synchronization tick
