Struct NodeView 

pub struct NodeView<'a> { /* private fields */ }

One node of a laid-out window: a widget, or the window itself at the root. Draw it, then its children in order, so later ones are on top.

Implementations

impl<'a> NodeView<'a>

pub fn name(&self) -> &'static str

The widget type, such as "Row", or "PanelWindow" at the root.

pub fn path(&self) -> &'a str

The widget path, such as PanelWindow[DP-1]/Row/Button[2].

pub fn rect(&self) -> Rect

The rectangle from the last layout, in window coordinates. Empty before the first layout.

pub fn bounds(&self) -> Rect

The area the node and everything inside it painted at the last layout: its rectangle, text and icons that overflow it, and its descendants’ bounds, moved by its transform into its parent’s coordinates. Nothing outside it needs drawing for this node.

pub fn inner_bounds(&self) -> Rect

bounds before the node’s own transform, in its own coordinates: what a layer drawn for the transform must hold. The same as bounds when it has none.

pub fn transform(&self) -> Option<Affine>

How the node’s style moves it and everything inside it where it is drawn, from its own coordinates, which its rectangle and its children’s are in, into its parent’s. None when it doesn’t. The whole subtree is drawn as one layer through it.

pub fn style(&self) -> Style

The style in effect, with a button’s hover and pressed styles laid over its own. Inherited fields aren’t filled in; TextView::color has the color text is drawn in.

pub fn children(&self) -> impl Iterator<Item = NodeView<'a>> + 'a

The children, in drawing order.

pub fn clips(&self) -> bool

Whether the node cuts its children to the inside of its border: a clipping style or a scroll view.

pub fn content(&self) -> Content<'a>

What the node draws besides its background and border.

Trait Implementations

impl<'a> Clone for NodeView<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
