GPUI Dependency Types ​

These are GPUI types, not Vektra types. Vektra uses them at public callback boundaries without copying their full definitions. Every link is pinned to commit fd82517a115d97a07835b52f0512b22b38e38ccf.

ClickEvent ​

Used only by raw activation entries such as Clickable::on_click. Changeable::on_change carries no click event because changes may also originate from arrow keys, Home, or End. Pinned source.

Window ​

The current window's focus, input, drawing, and platform-state entry point. Vektra callbacks receive &mut Window. Pinned source.

App ​

GPUI's application-level context. Standard builder callbacks receive &mut App. Pinned source.

Context<T> ​

The update context for Entity T. *_in methods use Context::listener to bind standard callbacks to the host Entity and retain GPUI's weak-reference/no-op behavior after destruction. Pinned source.

Entity<T> and SharedString ​

Input requires the caller to own an Entity<InputState>, keeping editing state stable across renders. SharedString is Input's public value/event string type, while InputState::value() exposes content as &str.

Internally, Input implements the pinned revision's EntityInputHandler and connects it through ElementInputHandler for platform text input, IME, UTF-16 selection, and range bounds. These are implementation details and require no global handler registration by the host.

This Entity-bound example is compiled into the real WASM preview:

rust
.on_focus_in(cx, move |this, _, cx| {
    this.record_focus(controlled, true, cx);
})
.on_blur_in(cx, move |this, _, cx| {
    this.record_focus(controlled, false, cx);
}),

If GPUI later publishes stable official docs that match this revision, these links can move there. Until then, pinned source remains the signature authority.
