Button

A clickable button (GuiElementType::Button).

use factorio_rs::factorio_api::lua_fn;
use factorio_rs_gui::shared::button::Button;

let on_ok = lua_fn(move |event: OnGuiClickEvent| {
    let _ = event;
    // ...
});

Button::new("OK").on_click(on_ok)

Builder API

Method	Effect
new(&str)	Button with caption
name(&str)	Optional stable element name
on_click(LuaFunction)	Click handler (lua_fn / lua_fn0 / function item)

If on_click is set and you omit .name(...), the runtime assigns a unique name (frg_btn...) so the click can be routed.

Events

mount / install register dispatch_click on your mod’s script. You do not need a manual OnGuiClick stub. For extra click logic (when no named button matched), use runtime::on_click.
