Enum gdk4::Gravity

#[non_exhaustive]
pub enum Gravity {
    NorthWest,
    North,

    West,
    Center,
    East,
    SouthWest,
    South,
    SouthEast,
    Static,
    // some variants omitted
}

Defines the reference point of a surface and is used in PopupLayout.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NorthWest

the reference point is at the top left corner.

North

the reference point is in the middle of the top edge.

NorthEast

the reference point is at the top right corner.

West

the reference point is at the middle of the left edge.

Center

the reference point is at the center of the surface.

East

the reference point is at the middle of the right edge.

SouthWest

the reference point is at the lower left corner.

South

the reference point is at the middle of the lower edge.

SouthEast

the reference point is at the lower right corner.

Static

the reference point is at the top left corner of the surface itself, ignoring window manager decorations.
