SetAppIcon

Blocking API

This operation is synchronous; it will prevent the event loop from running while the request is being handled.

Sets the application icon for the native window that the WebView is running in. Loading is handled by the underlying OS, but it's generally blocking. Additionally, you must ensure that the app icon is provided in a compatible format for each platform:

• On Windows, icons must use the ICO format
• Mac OS app icons use the Apple Icon Image format
• On Linux, standard formats like JPG or PNG can be used (assuming a loader is present)

Depending on the OS and its version, the icon may appear in different locations (e.g., OSX Dock and Windows task bar).

Available since: v0.0.2
