Events that the windowing system sends to Servo.

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.

Resize

Sent when the window is resized.

AllowNavigationResponse(PipelineId, bool)

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

Tuple Fields of AllowNavigationResponse

0: PipelineId1: bool

LoadUrl(TopLevelBrowsingContextId, ServoUrl)

Sent when a new URL is to be loaded.

Tuple Fields of LoadUrl

0: TopLevelBrowsingContextId1: ServoUrl

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.

Tuple Fields of Wheel

0: WheelDelta1: DevicePoint

Scroll(ScrollLocation, DeviceIntPoint, TouchEventType)

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

Tuple Fields of Scroll
