Struct ResizableState 

pub struct ResizableState { /* private fields */ }

State for a ResizablePanel

Implementations

impl ResizableState

pub fn sizes(&self) -> &Vec<Pixels>

Get the size of the panels.

pub fn resize_panel( &mut self, ix: usize, size: Pixels, window: &mut Window, cx: &mut Context<'_, Self>, )

Programmatically resize the panel at ix to size, redistributing space among siblings using the same logic as a drag.

Sizes are clamped to the panel’s size_range and to the container. Emits ResizablePanelEvent::Resized so subscribers (e.g. preference persistence) see the change just as if the user had dragged a handle.

Out-of-range indices are a no-op. For the last panel, space is taken from the previous sibling (the last panel has no handle of its own).

pub fn insert_panel( &mut self, size: Option<Pixels>, ix: Option<usize>, cx: &mut Context<'_, Self>, )

Insert a panel state at ix, or append it when no index is supplied.

Existing panel sizes are redistributed so their total remains equal to the current container size.

pub fn remove_panel(&mut self, panel_ix: usize, cx: &mut Context<'_, Self>)

Remove the panel at panel_ix and redistribute the remaining space.

pub fn reset_panel(&mut self, panel_ix: usize, cx: &mut Context<'_, Self>)

Reset the panel at panel_ix while preserving its current size.

pub fn clear(&mut self)

Remove all panel state.

pub fn container_size(&self) -> Pixels

Return the measured size of the group along its resize axis.
