Enum WindowKind 

pub enum WindowKind {
    Normal,
    Popup,
}

What kind of OS surface a declared window is.

Variants

Normal

A regular top-level window with the launcher’s chrome.

Popup

A menu surface: borderless, absent from the taskbar, owned by the window that declared it and closed when that window closes, placed in screen coordinates against WindowConfig::anchor rather than clamped into a viewport, and non-activating by default — it must not take OS focus, or opening a combobox would blur the field that opened it. While a non-activating popup is up the driver routes its owner’s keyboard input to it and the owner’s env.focused stays true, so the field still draws focused while the arrow keys walk the list.

Reach for it only for the placements a float cannot make: a list taller than the window, a menu near an edge with nowhere in-window to go, a panel beside the app. Everything else is cheaper as a float (crate::spec::FloatConfig::fit): a float costs one tree and one draw call, a popup an OS surface, a swapchain and a Core.

Implementations

impl WindowKind

pub const ALL: [WindowKind; 2]

Every kind, in wire order: the index a binding that spells kinds as numbers sends. Append-only.

pub fn name(self) -> &'static str

The wire name, for the bindings and the report.

pub fn from_name(name: &str) -> Option<WindowKind>

The kind a wire name spells: the inverse of Self::name.
