Enum PopupAnchor

pub enum PopupAnchor {
    ParentRect(Rect),
    Pointer,
    PointerFixed,
    Position(Pos2),
}

What should we anchor the popup to?

The final position for the popup will be calculated based on RectAlign and can be customized with Popup::align and Popup::align_alternatives. PopupAnchor is the parent rect of RectAlign.

For PopupAnchor::Pointer, PopupAnchor::PointerFixed and PopupAnchor::Position, the rect will be derived via Rect::from_pos (so a zero-sized rect at the given position).

The rect should be in global coordinates. PopupAnchor::from(&response) will automatically do this conversion.

Variants

ParentRect(Rect)

Show the popup relative to some parent Rect.

Pointer

Show the popup relative to the mouse pointer.

PointerFixed

Remember the mouse position and show the popup relative to that (like a context menu).

Position(Pos2)

Show the popup relative to a specific position.

Implementations

impl PopupAnchor

pub fn rect(self, popup_id: Id, ctx: &Context) -> Option<Rect>

Get the rect the popup should be shown relative to. Returns Rect::from_pos for PopupAnchor::Pointer, PopupAnchor::PointerFixed and PopupAnchor::Position (so the rect will be zero-sized).

Trait Implementations

impl Clone for PopupAnchor

fn clone(&self) -> PopupAnchor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PopupAnchor

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

Formats the value using the given formatter.

impl From<&Response> for PopupAnchor

fn from(response: &Response) -> Self

Converts to this type from the input type.

impl From<Pos2> for PopupAnchor

fn from(pos: Pos2) -> Self

Converts to this type from the input type.

impl From<Rect> for PopupAnchor

fn from(rect: Rect) -> Self

Converts to this type from the input type.

impl PartialEq for PopupAnchor

fn eq(&self, other: &PopupAnchor) -> 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.
