From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Shelley Vohr Date: Mon, 6 Jul 2020 13:46:06 -0700 Subject: Adjust accessibility_ui for Electron This tweaks Chrome's Accessibility support at chrome://accessibility to make it usable from Electron by replacing use of the Profile PrefService with Electron's own PrefService in ElectronBrowserContext. It also removes usage of BrowserList and Browser as we subclass related methods and use our WindowList. diff --git a/chrome/browser/ui/webui/accessibility/accessibility_ui.cc b/chrome/browser/ui/webui/accessibility/accessibility_ui.cc index aff8a187b6d81172bf5930c6da6bfed4d7989057..5923e39ae94cabd716d845c86db5f84c3c51e2cb 100644 --- a/chrome/browser/ui/webui/accessibility/accessibility_ui.cc +++ b/chrome/browser/ui/webui/accessibility/accessibility_ui.cc @@ -43,6 +43,7 @@ #include "content/public/browser/web_contents.h" #include "content/public/browser/web_contents_delegate.h" #include "content/public/browser/web_ui_data_source.h" +#include "electron/shell/browser/electron_browser_context.h" #include "ui/accessibility/accessibility_features.h" #include "ui/accessibility/ax_updates_and_events.h" #include "ui/accessibility/platform/ax_platform_node.h" @@ -169,7 +170,7 @@ base::Value::Dict BuildTargetDescriptor(content::RenderViewHost* rvh) { accessibility_mode);
