Enum gtk::WindowPosition

#[non_exhaustive]pub enum WindowPosition {
    None,
    Center,
    Mouse,
    CenterAlways,
    CenterOnParent,
    // some variants omitted
}

Window placement can be influenced using this enumeration. Note that using WindowPosition::CenterAlways is almost always a bad idea. It won’t necessarily work well with all window managers or on all windowing systems.

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.

None

No influence is made on placement.

Center

Windows should be placed in the center of the screen.

Mouse

Windows should be placed at the current mouse position.

CenterAlways

Keep window centered as it changes size, etc.

CenterOnParent

Center the window on its transient parent (see GtkWindowExt::set_transient_for).
