Struct termwiz::widgets::layout::LayoutState

source · [−]

pub struct LayoutState { /* private fields */ }

Expand description

Holds state used to compute the layout of a tree of widgets

Implementations

source

impl LayoutState

source

pub fn new() -> Self

Create a new LayoutState

source

pub fn add_widget(
    &mut self,
    widget: WidgetId,
    constraints: &Constraints,
    children: &[WidgetId]
)

Creates a WidgetState entry for a widget.

source

pub fn compute_constraints(
 &mut self,
 screen_width: usize,
 screen_height: usize,
 root_widget: WidgetId
) -> Result<Vec<LaidOutWidget>>

Assign the screen dimensions, compute constraints, solve the layout and then apply the size and positioning information to the widgets in the widget tree.
