BrowserRenderer

Struct BrowserRenderer 

Source
pub struct BrowserRenderer {
    pub render_state: RenderState,
    pub chrome: Box<dyn Chrome>,
    pub menu: Box<dyn ContextMenu>,
}
Expand description

BrowserRenderer は実際の描画を担当する。

責務:

  • アクティブタブのページとブラウザ chrome から DrawCommand を生成する
  • DevTools ペインが開いている場合は分割ビューとして両ペインを生成する
  • 開いているコンテキストメニューを最前面オーバーレイとして生成する
  • DrawCommand をプラットフォームの GPU レンダラへ渡し、描画を実行する
  • ウィンドウのサイズ・スケール・タイトルなどの描画状態を保持する

BrowserApp / BrowserUi は直接の描画実装を持たず、このレンダラへ処理を委譲する。

Fields§

§render_state: RenderState

ウィンドウの描画状態(DrawCommand、サイズ、スケール、タイトル)。

§chrome: Box<dyn Chrome>

ブラウザ chrome(ツールバーなどの UI 描画)。既定は BasicChrome

§menu: Box<dyn ContextMenu>

WebView 右クリックで開くコンテキストメニュー。既定は BasicContextMenu
