Description:

webview2-gtk API - Package Overview

GTK 4 widget embedding Microsoft Edge WebView2 on Windows, plus Win32Atspi (AT-SPI-shaped accessibility over UI Automation).

Public namespaces:

• WebView2Gtk — WebView and related types (WebKitGTK-shaped API)
• Win32Atspi — accessibility tree / actions / keyboard synth

Hand-written notes: docs/a11y.md.

WebView

• WebView2Gtk.WebView
• WebView2Gtk.WebResource
• WebView2Gtk.Download

Accessibility

• Win32Atspi
• Win32Atspi.Accessible

Interfaces:

• PermissionRequest - WebKitGTK- shaped — allow/deny a permission prompt.

Classes:

• ApplicationInfo - WebKitGTK-shaped application info for an AutomationSession.
• AutomationSession - WebKitGTK-shaped automation session(browser side).
• CookieManager
• Download - WebKitGTK-shaped download — hold until set_destination / cancel.
• JavaScriptResult
• NetworkProxySettings
• NetworkSession - WebKitGTK-shaped network session — cookies + download_started.
• PermissionStateQuery - WebKitGTK- shaped — answer a permission-state query (API parity; host may never emit).
• PrintOperation
• URIRequest - Minimal WebKit URIRequest stand- in(uri only — enough for OLLMchat).
• UserContentManager - WebKitGTK-shaped user content manager — script message handlers for 2.0.
• WebContext - WebKitGTK-shaped web context — automation allow + session signal.
• WebInspector - WebKitGTK-shaped inspector — show opens the host DevTools window.
• WebResource - WebKitGTK-shaped web resource — in-flight subresource for load tracking.
• WebView - Embeds WebView2 in a GTK 4 window using the toplevel Win32 HWND from `gdk_win32_surface_get_handle()` on the native surface.
• WebViewSettings
• WebsitePolicies - WebKitGTK-shaped website policies for a WebView.

Enums:

• AutoplayPolicy - WebKitGTK-shaped — media autoplay policy for WebsitePolicies.
• CookieAcceptPolicy
• CookiePersistentStorage

• LoadEvent - Load lifecycle events — same names and order as WebKit.LoadEvent.
• NetworkProxyMode
• PermissionState - WebKitGTK-shaped — result of PermissionStateQuery.finish.
• SnapshotOptions
• SnapshotRegion
• TLSErrorsPolicy

Error domains:

• NetworkError - WebKitGTK-shaped subset — used by WebView.load_failed.
• Win32Atspi

Classes:

• Accessible - One node in the emulated AT-SPI tree(backed by UIA walk cache ids where set).
• ComponentExtents
• Hyperlink
• Text

Enums:

• CoordType
• KeySynthType
• ScrollType

Methods:

• public void generate_keyboard_event (long keyval, string? keystring, KeySynthType synth)
• public Accessible get_desktop (int index)
• public void init ()
• public void register_webview (WebView web)
  Register the WebView that backs this process's AT-SPI tree. Called automatically when WebView2Gtk.WebView becomes ready.
