Required Methods§

Source

fn new() -> Self
where Self: Sized,

Source

fn events_tf( &mut self, world: World, history: History, events: &Events, ) -> (World, History)

All events that are used by a tool are implemented in here. Use the macro make_tool_transform. See, e.g., Zoom::events_tf.

Provided Methods§

fn on_activate(&mut self, world: World) -> World

Source

fn on_deactivate(&mut self, world: World) -> World

fn on_filechange(&mut self, world: World, history: History) -> (World, History)

Source

fn on_always_active_zoom( &mut self, world: World, history: History, ) -> (World, History)

Source

fn has_been_used(&self, _: &Events) -> Option<bool>

None -> the tool does not tell you if it has been used Some(true) -> the tool has been used Some(false) -> the tool has not been used
