Struct AreaState

pub struct AreaState {
    pub pivot_pos: Option<Pos2>,
    pub pivot: Align2,
    pub size: Option<Vec2>,
    pub interactable: bool,
    pub last_became_visible_at: Option<f64>,
}

State of an Area that is persisted between frames.

Areas back crate::Windows and other floating containers, like tooltips and the popups of crate::ComboBox.

Fields

pivot_pos: Option<Pos2>

Last known position of the pivot.

pivot: Align2

The anchor point of the area, i.e. where on the area the Self::pivot_pos refers to.

size: Option<Vec2>

Last known size.

Area size is intentionally NOT persisted between sessions, so that a bad tooltip or menu size won’t be remembered forever. A resizable crate::Window remembers the size the user picked using the state in the crate::Resize container.

interactable: bool

If false, clicks goes straight through to what is behind us. Useful for tooltips etc.

last_became_visible_at: Option<f64>

At what time was this area first shown?

Used to fade in the area.
