Struct kas::event::ManagerState

pub struct ManagerState { /* fields omitted */ }

Event manager state

This struct encapsulates window-specific event-handling state and handling. Most operations are only available via a Manager handle, though some are available on this struct.

Besides event handling, this struct also configures widgets.

Some methods are intended only for usage by KAS shells and are hidden from documentation unless the internal_doc feature is enabled. Only winit events are currently supported; changes will be required to generalise this.

Implementations

impl ManagerState

Public API (around event manager state)

pub fn show_accel_labels(&self) -> bool

True when accelerator key labels should be shown

(True when Alt is held and no widget has character focus.)

This is a fast check.

pub fn has_char_focus(&self, w_id: WidgetId) -> (bool, bool)

Get whether this widget has (char_focus, sel_focus)

• char_focus: implies this widget receives keyboard input
• sel_focus: implies this widget is allowed to select things

Note that char_focus implies sel_focus.

pub fn nav_focus(&self, w_id: WidgetId) -> bool

Get whether this widget has keyboard navigation focus

pub fn is_hovered(&self, w_id: WidgetId) -> bool

Get whether the widget is under the mouse cursor

pub fn is_depressed(&self, w_id: WidgetId) -> bool

Check whether the given widget is visually depressed
