Enum WindowCommand 

pub enum WindowCommand {
    Drag,
    Minimize,
    ToggleMaximize,
    SetMaximized(bool),
    Close,
    SetTitle(String),
    Focus,
    SetCursor(Cursor),
}

A window-management action requested by UI code (a custom title bar’s buttons) and applied by the runner to the OS window after event dispatch. Enqueued via push_window_command and drained via take_window_commands; kept as data (rather than direct Window calls) because widget closures run deep in the tree walk with no access to the platform window.

Variants

Drag

Begin an OS-driven interactive move (drag the window by its title bar). Must originate from a pointer-press handler so the platform can latch onto the in-progress drag.

Minimize

Minimize the window to the taskbar/dock.

ToggleMaximize

Toggle between maximized and restored.

SetMaximized(bool)

Explicitly set the maximized state.

Close

Close the window (and, for a single-window app, exit the app).

SetTitle(String)

Update the OS window title.

Focus

Bring the window to the front and give it input focus. Honored where the window manager allows programmatic activation (some Wayland compositors ignore it).

SetCursor(Cursor)

Set the pointer shape. Pushed from a hover handler, which is why it is a command rather than a property: the widget under the pointer decides, and it changes many times per second.
