Struct gdk::AnchorHints

pub struct AnchorHints { /* fields omitted */ }

Positioning hints for aligning a window relative to a rectangle.

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

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

If AnchorHints::SlideX is set, the window can be shifted horizontally to fit on-screen. If AnchorHints::ResizeX is set, the window 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.
