Trait for the unit of UI composition.

Required methods

fn print(&self, id: ViewID, cx: &mut Context)

Prints a description of the view for debugging.

fn process(&self, event: &Event, id: ViewID, cx: &mut Context, vger: &mut VGER)

Processes an event.

fn draw(&self, id: ViewID, cx: &mut Context, vger: &mut VGER)

Draws the view using vger.

fn layout(
    &self,
    id: ViewID,
    sz: LocalSize,
    cx: &mut Context,
    vger: &mut VGER
) -> LocalSize

Lays out subviews and return the size of the view.

fn hittest(
    &self,
    id: ViewID,
    pt: LocalPoint,
    cx: &mut Context,
    vger: &mut VGER
) -> Option<ViewID>

Returns the topmost view which the point intersects.

fn commands(&self, id: ViewID, cx: &mut Context, cmds: &mut Vec<CommandInfo>)

Accumulates information about menu bar commands.

fn gc(&self, id: ViewID, cx: &mut Context, map: &mut StateMap)

Copies state currently in use to a new StateMap (the rest are dropped).

fn access(
    &self,
    id: ViewID,
    cx: &mut Context,
    nodes: &mut Vec<Node>
) -> Option<NodeId>

Builds an AccessKit tree. The node ID for the subtree is returned. All generated nodes are accumulated.
