Struct LayoutNode 

pub struct LayoutNode {
    pub rect: Rect,
    pub id: Option<String>,
    pub on_click: Option<String>,
    pub children: Vec<LayoutNode>,
    pub enabled: bool,
    pub focused: bool,
    pub content_h: f32,
    pub scroll_y: f32,
    pub clip: bool,
    pub scrollbar: bool,
    pub action: Option<Action>,
    pub visible: bool,
}

Fields

rect: Rect

id: Option<String>

on_click: Option<String>

children: Vec<LayoutNode>

enabled: bool

focused: bool

content_h: f32

Height of everything inside — children plus padding — before scrolling. Larger than rect.h when the children overflow.

scroll_y: f32

Effective vertical scroll offset: the widget’s scroll_y clamped to 0..=Self::max_scroll. Children are already shifted by it.

clip: bool

The widget clips its children (see Style::clip).

scrollbar: bool

The widget shows a scrollbar on overflow (see Style::scrollbar).

action: Option<Action>

The widget’s typed click target (see Widget::action).

visible: bool

false = collapsed (see Widget::visible): a zero rect, no children, never hit.

Implementations

impl LayoutNode

pub fn max_scroll(&self) -> f32

How far the children can scroll: content_h - rect.h, at least 0.

pub fn scrollbar_rects(&self) -> Option<(Rect, Rect)>

Scrollbar track and knob rects — None unless the widget has a scrollbar and its content overflows.

impl LayoutNode

pub fn is_clickable(&self) -> bool

Clicking it does something: it has an action or on_click, is enabled and visible.

Trait Implementations

impl Clone for LayoutNode

fn clone(&self) -> LayoutNode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LayoutNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for LayoutNode

fn default() -> LayoutNode

Returns the “default value” for a type.
