pub fn new( app_sender: AppSender, view_key: ViewKey, split: ScreenSplit, text1: Option<String>, text2: Option<String>, text3: Option<String>, button_infos1: Option<Vec<ButtonInfo>>, button_infos2: Option<Vec<ButtonInfo>>, permission_button_infos: Option<Vec<ButtonInfo>>, icon_name: Option<&'static str>, icon_size: Option<Size2D<f32, UnknownUnit>>, ) -> Result<GenericSplitViewAssistant, Error>

Trait Implementations

impl ViewAssistant for GenericSplitViewAssistant

fn resize(&mut self, _new_size: &Size) -> Result<(), Error>

Implement this method to to handle when a view is resized.

fn render( &mut self, render_context: &mut RenderContext, ready_event: Event, context: &ViewAssistantContext, ) -> Result<(), Error>

This method is called when a view needs to be rendered.

fn handle_pointer_event( &mut self, context: &mut ViewAssistantContext, _event: &Event, pointer_event: &Event, ) -> Result<(), Error>

This method is called when the view desires pointer events and a compatible mouse or touch event comes to this view.

fn handle_message(&mut self, message: Message)

This method is called when App::send_message is called with the associated view controller’s ViewKey and the view controller does not handle the message.

fn setup(&mut self, context: &ViewAssistantContext) -> Result<(), Error>

This method is called once when a view is created.

fn get_scene(&mut self, size: Size2D<f32, UnknownUnit>) -> Option<&mut Scene>

Implement this method to return a mutable reference to the scene that represents the view.

fn get_scene_with_contexts( &mut self, render_context: &mut Context, view_context: &ViewAssistantContext, ) -> Option<&mut Scene>

Implement this method to return a mutable reference to the scene that represents the view. Implement this one if you’ll need the various contexts to build a scene.

fn handle_input_event( &mut self, context: &mut ViewAssistantContext, event: &Event, ) -> Result<(), Error>

This method is called when input events come to this view. The default implementation calls specific methods for the type of event, so usually one does not need to implement this method. Since the default methods for touch and mouse handle the pointer abstraction, make sure to call them in an implementation of this method if you wish to use that abstraction.

fn handle_mouse_event( &mut self, context: &mut ViewAssistantContext, event: &Event, mouse_event: &Event, ) -> Result<(), Error>

This method is called when mouse events come to this view.

fn handle_touch_event( &mut self, context: &mut ViewAssistantContext, event: &Event, touch_event: &Event, ) -> Result<(), Error>

This method is called when touch events come to this view.

fn handle_keyboard_event( &mut self, context: &mut ViewAssistantContext, event: &Event, keyboard_event: &Event, ) -> Result<(), Error>

This method is called when keyboard events come to this view.

fn handle_consumer_control_event( &mut self, context: &mut ViewAssistantContext, event: &Event, consumer_control_event: &Event, ) -> Result<(), Error>

This method is called when consumer control events come to this view.

fn handle_focus_event( &mut self, context: &mut ViewAssistantContext, focused: bool, ) -> Result<(), Error>

This method is called when focus events come from Scenic to this view. It will be called once when a Carnelian app is running directly on the frame buffer, as such views are always focused. See the button sample for an one way to respond to focus.

fn uses_pointer_events(&self) -> bool

Whether this view wants touch and mouse events abstracted as input::pointer::Event. Defaults to true.

fn ownership_changed(&mut self, _owned: bool) -> Result<(), Error>

This method is called when running directly on the display and the ownership of the display changes.

fn get_render_offset(&mut self) -> Option<i64>

This method is called after setup to get an offset to use when calculating render time. It is only called once.
