Struct PaneGrid 

pub struct PaneGrid<'a, Message, Theme = Theme, Renderer = Renderer>
where
    Theme: Catalog,
    Renderer: Renderer,
{ /* private fields */ }

A collection of panes distributed using either vertical or horizontal splits to completely fill the space available.

This distribution of space is common in tiling window managers (like awesome, i3, or even tmux).

A PaneGrid supports:

• Vertical and horizontal splits
• Tracking of the last active pane
• Mouse-based resizing
• Drag and drop to reorganize panes
• Hotkey support
• Configurable modifier keys
• State API to perform actions programmatically (split, swap, resize, etc.)

Example

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()
}

Implementations

impl<'a, Message, Theme, Renderer> PaneGrid<'a, Message, Theme, Renderer>

where Theme: Catalog, Renderer: Renderer,

pub fn new<T>( state: &'a State<T>, view: impl Fn(Pane, &'a T, bool) -> Content<'a, Message, Theme, Renderer>, ) -> Self

Creates a PaneGrid with the given State and view function.

The view function will be called to display each Pane present in the State. bool is set if the pane is maximized.

pub fn width(self, width: impl Into<Length>) -> Self

Sets the width of the PaneGrid.

pub fn height(self, height: impl Into<Length>) -> Self

Sets the height of the PaneGrid.

pub fn spacing(self, amount: impl Into<Pixels>) -> Self

Sets the spacing between the panes of the PaneGrid.

pub fn min_size(self, min_size: impl Into<Pixels>) -> Self

Sets the minimum size of a Pane in the PaneGrid on both axes.

pub fn on_click<F>(self, f: F) -> Self

where F: 'a + Fn(Pane) -> Message,

Sets the message that will be produced when a Pane of the PaneGrid is clicked.

pub fn on_drag<F>(self, f: F) -> Self

where F: 'a + Fn(DragEvent) -> Message,

Enables the drag and drop interactions of the PaneGrid, which will use the provided function to produce messages.

pub fn on_resize<F>(self, leeway: impl Into<Pixels>, f: F) -> Self

where F: 'a + Fn(ResizeEvent) -> Message,

Enables the resize interactions of the PaneGrid, which will use the provided function to produce messages.

The leeway describes the amount of space around a split that can be used to grab it.

The grabbable area of a split will have a length of spacing + leeway, properly centered. In other words, a length of (spacing + leeway) / 2.0 on either side of the split line.

pub fn style(self, style: impl Fn(&Theme) -> Style + 'a) -> Self

where <Theme as Catalog>::Class<'a>: From<StyleFn<'a, Theme>>,

Sets the style of the PaneGrid.

pub fn class(self, class: impl Into<<Theme as Catalog>::Class<'a>>) -> Self

Available on crate feature advanced only.

Sets the style class of the PaneGrid.
