Implementations

impl Minibrowser

pub fn new( rendering_context: Rc<OffscreenRenderingContext>, event_loop: &ActiveEventLoop, initial_url: ServoUrl, ) -> Self

pub(crate) fn take_events(&self) -> Vec<MinibrowserEvent>

pub fn on_window_event( &mut self, window: &Window, app_state: &RunningAppState, event: &WindowEvent, ) -> EventResponse

Preprocess the given winit::event::WindowEvent, returning unconsumed for mouse events in the Servo browser rect. This is needed because the CentralPanel we create for our webview would otherwise make egui report events in that area as consumed.

fn is_in_egui_toolbar_rect( &self, position: Point2D<f32, DeviceIndependentPixel>, ) -> bool

Return true iff the given position is over the egui toolbar.

fn toolbar_button(text: &str) -> Button<'_>

Create a frameless button with square sizing, as used in the toolbar.

fn browser_tab( ui: &mut Ui, webview: WebView, event_queue: &mut Vec<MinibrowserEvent>, )

Draws a browser tab, checking for clicks and queues appropriate MinibrowserEvents. Using a custom widget here would’ve been nice, but it doesn’t seem as though egui supports that, so we arrange multiple Widgets in a way that they look connected.

pub fn update( &mut self, window: &Window, state: &RunningAppState, reason: &'static str, )

Update the minibrowser, but don’t paint. If servo_framebuffer_id is given, set up a paint callback to blit its contents to our CentralPanel when Minibrowser::paint is called.

pub fn paint(&mut self, window: &Window)

Paint the minibrowser, as of the last update.

pub fn update_location_in_toolbar(&mut self, state: &RunningAppState) -> bool

Updates the location field from the given [WebViewManager], unless the user has started editing it without clicking Go, returning true iff it has changed (needing an egui update).

pub fn update_location_dirty(&self, dirty: bool)

pub fn update_load_status(&mut self, state: &RunningAppState) -> bool

pub fn update_status_text(&mut self, state: &RunningAppState) -> bool

pub fn update_webview_data(&mut self, state: &RunningAppState) -> bool

Updates all fields taken from the given [WebViewManager], such as the location field. Returns true iff the egui needs an update.

Trait Implementations

impl Drop for Minibrowser

fn drop(&mut self)

Executes the destructor for this type.
