Struct GlobalState 

pub struct GlobalState { /* private fields */ }

Application-wide state shared by Base behaviors.

Implementations

impl GlobalState

pub fn note_touch(cx: &mut App)

Records that a finger went down. Called from the touch drag GPUI offers on every touch, before it becomes a tap, a long press or a pan.

pub fn is_touch_press(cx: &App) -> bool

Whether the press being handled came from a finger: a touch went down recently enough that the mouse events of a tap are still arriving. A double tap takes up to twice the tap interval.

pub fn suppress_text_selection(cx: &mut App)

Suppresses window-level text selection for the current mouse down.

Controls that own a press or drag interaction use this so the same pointer event does not also start application text selection.

pub fn global(cx: &App) -> &Self

pub fn global_mut(cx: &mut App) -> &mut Self

pub fn app_menus(&self) -> &[OwnedMenu]

Returns the application menus.

pub fn set_app_menus(&mut self, menus: Vec<OwnedMenu>)

Replaces the application menus.

pub fn is_in_deferred_context(cx: &App) -> bool

Returns whether any deferred popup currently owns an open interaction context.

pub fn register_deferred_popover(cx: &mut App) -> DeferredPopover

Registers an open deferred popup, which stays registered for as long as the returned token is held.

A token rather than an identifier, because popup state is routinely dropped without ever being closed: state that stops being rendered — a popover scrolled out of a virtual list, a panel closed while its menu is open — is collected at the end of the frame, with no chance to deregister. A registration that outlived its popup would leave the application believing a popup is open forever, and everything that steps aside for open popups (the native context menu of a text input, say) would stay disabled for the rest of the session.
