Struct WidgetRect

pub struct WidgetRect {
    pub id: Id,
    pub layer_id: LayerId,
    pub rect: Rect,
    pub interact_rect: Rect,
    pub sense: Sense,
    pub enabled: bool,
}

Used to store each widget’s Id, Rect and Sense each frame.

Used to check which widget gets input when a user clicks somewhere.

Fields

id: Id

The globally unique widget id.

For interactive widgets, this better be globally unique. If not there will be weird bugs, and also big red warning test on the screen in debug builds (see crate::Options::warn_on_id_clash).

You can ensure globally unique ids using crate::Ui::push_id.

layer_id: LayerId

What layer the widget is on.

rect: Rect

The full widget rectangle.

interact_rect: Rect

Where the widget is.

This is after clipping with the parent ui clip rect.

sense: Sense

How the widget responds to interaction.

Note: if Self::enabled is false, then the widget effectively doesn’t sense anything, but can still have the same Sense. This is because the sense informs the styling of the widget, but we don’t want to change the style when a widget is disabled (that is handled by the Painter directly).

enabled: bool

Is the widget enabled?

Trait Implementations

impl Clone for WidgetRect

fn clone(&self) -> WidgetRect

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WidgetRect

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

Formats the value using the given formatter.

impl PartialEq for WidgetRect

fn eq(&self, other: &WidgetRect) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
