Constructor - Pane Grid

Authoritative source: ref/doc/iced/widget/fn.pane_grid.html.

# Rustdoc summary

Creates a PaneGrid with the given pane_grid::State and view function.

# Verified signature

rust
pub fn pane_grid<'a, T, Message, Theme, Renderer>(
    state: &'a State<T>,
    view: impl Fn(Pane, &'a T, bool) -> Content<'a, Message, Theme, Renderer>,
) -> PaneGrid<'a, Message, Theme, Renderer>
where
    Theme: Catalog,
    Renderer: Renderer,

# When to use

Use this constructor/helper as the typed entrypoint for the widget or layout helper it creates.

# Why to use

It gives explicit widget construction with compile-time type checking and builder chaining.

# Example References

  • ref/examples/pane_grid/src/main.rs

# Inline Examples (from rustdoc)

rust
use iced::widget::{pane_grid, text};

struct State {
    panes: pane_grid::State<Pane>,
}

enum Pane {
    SomePane,
    AnotherKindOfPane,
}

enum Message {
    PaneDragged(pane_grid::DragEvent),
    PaneResized(pane_grid::ResizeEvent),
}

fn view(state: &State) -> Element<'_, Message> {
    pane_grid(&state.panes, |pane, state, is_maximized| {
        pane_grid::Content::new(match state {
            Pane::SomePane => text("This is some pane"),
            Pane::AnotherKindOfPane => text("This is another kind of pane"),
        })
    })
    .on_drag(Message::PaneDragged)
    .on_resize(10, Message::PaneResized)
    .into()
}

# Use this when...

  • You want the canonical entrypoint for creating this widget/helper.
  • You need concrete constructor arguments and builder chaining.
  • You are wiring UI interactions into typed messages.

# Minimal example

rust
// Call this constructor in `view`, then map events to Message variants.

# How it works

Constructors return typed widget values. You configure behavior via builder methods and emit Message values for update to handle.

# Common patterns

rust
// Keep constructor calls close to their message mapping.
// Prefer small helper functions for repeated widget setups.

# Gotchas / tips

  • Re-check argument order in the verified signature on this page.
  • Keep side effects out of view; trigger them from update with Task.
  • Use the related family page when deciding between module/element APIs.
