pub struct UndoMix<P>(/* private fields */);Expand description
m Undo scope widget mixin.
Widget is an undo/redo scope, it tracks changes and handles undo/redo commands.
You can force the widget to use a parent undo scope by setting undo_scope to false, this will cause the widget
to start registering undo/redo actions in the parent, note that the widget will continue behaving as if it
owns the scope, so it may clear it.
Implementations§
source§impl<P> UndoMix<P>where
P: WidgetImpl,
impl<P> UndoMix<P>where
P: WidgetImpl,
sourcepub fn undo_enabled(&self, enabled: impl IntoVar<bool>)
pub fn undo_enabled(&self, enabled: impl IntoVar<bool>)
P If the widget can register undo actions.
Is true by default in this widget, if set to false disables undo in the widget.
sourcepub fn undo_limit(&self, limit: impl IntoVar<u32>)
pub fn undo_limit(&self, limit: impl IntoVar<u32>)
P Sets the maximum number of undo/redo actions that are retained in the widget.
sourcepub fn undo_interval(&self, interval: impl IntoVar<Duration>)
pub fn undo_interval(&self, interval: impl IntoVar<Duration>)
P Sets the time interval that undo and redo cover each call for undo handlers in the widget and descendants.
When undo is requested inside the context all actions after the latest that are within interval of the
previous are undone.
