Struct zng::focus::ReturnFocusChangedArgs

pub struct ReturnFocusChangedArgs {
    pub timestamp: DInstant,
    pub scope: Option<InteractionPath>,
    pub prev_return: Option<InteractionPath>,
    pub new_return: Option<InteractionPath>,
    /* private fields */
}

RETURN_FOCUS_CHANGED_EVENT arguments.

Fields

timestamp: DInstant

Instant the event happened.

scope: Option<InteractionPath>

The scope that returns the focus when focused directly.

Is None if the previous focus was the return focus of a scope that was removed.

prev_return: Option<InteractionPath>

Previous return focus of the widget.

new_return: Option<InteractionPath>

New return focus of the widget.

Implementations

impl ReturnFocusChangedArgs

pub fn new( timestamp: impl Into<DInstant>, propagation_handle: EventPropagationHandle, scope: impl Into<Option<InteractionPath>>, prev_return: impl Into<Option<InteractionPath>>, new_return: impl Into<Option<InteractionPath>>, ) -> ReturnFocusChangedArgs

New args from values that convert into the argument types.

pub fn now( scope: impl Into<Option<InteractionPath>>, prev_return: impl Into<Option<InteractionPath>>, new_return: impl Into<Option<InteractionPath>>, ) -> ReturnFocusChangedArgs

Arguments for event that happened now (INSTANT.now).

impl ReturnFocusChangedArgs

pub fn is_widget_move(&self) -> bool

If the return focus is the same widget but the widget path changed and the widget is still in the same focus scope.

pub fn is_alt_return(&self) -> bool

If scope is an ALT scope and prev_return or new_return if the widget outside the scope that will be focused back when the user escapes the ALT scope.

pub fn lost_return_focus(&self, widget_id: WidgetId) -> bool

if the widget was in the prev_return and is not in the new_return.

pub fn got_return_focus(&self, widget_id: WidgetId) -> bool

if the widget was not in the prev_return and is in the new_return.

pub fn was_return_focus(&self, widget_id: WidgetId) -> bool

if the widget was the prev_return and is the new_return.

pub fn is_return_focus(&self, widget_id: WidgetId) -> bool

if the widget was not the prev_return and is the new_return.

pub fn is_return_focus_enter(&self, widget_id: WidgetId) -> bool

If widget_id is the new return focus or a parent of the new return and was not a parent of the previous return.

pub fn is_return_focus_leave(&self, widget_id: WidgetId) -> bool

If widget_id is the previous return focus or a parent of the previous return and is not a parent of the new return.
