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
.fn on_activate(&mut self, world: World) -> World
fn on_deactivate(&mut self, world: World) -> World
fn on_filechange(&mut self, world: World, history: History) -> (World, History)
fn on_always_active_zoom( &mut self, world: World, history: History, ) -> (World, History)
Source§fn has_been_used(&self, _: &Events) -> Option<bool>
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
fn get_visibility(&self, _world: &World) -> Visibility
