Struct gdk4::AnchorHints

pub struct AnchorHints(/* private fields */);

Positioning hints for aligning a surface relative to a rectangle.

These hints determine how the surface should be positioned in the case that the surface would fall off-screen if placed in its ideal position.

For example, FLIP_X will replace Gravity::NorthWest with Gravity::NorthEast and vice versa if the surface extends beyond the left or right edges of the monitor.

If SLIDE_X is set, the surface can be shifted horizontally to fit on-screen. If RESIZE_X is set, the surface can be shrunken horizontally to fit.

In general, when multiple flags are set, flipping should take precedence over sliding, which should take precedence over resizing.

pub fn remove(&mut self, other: Self)

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl AnchorHints

pub const fn iter(&self) -> Iter<AnchorHints>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<AnchorHints>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
