scheme_handler

Scheme Handler Example Application

This directory contains the "scheme_handler" target which demonstrates how to handle resource requests using CefSchemeHandlerFactory.

See the shared library target for details common to all executable targets.

Implementation Overview

The "scheme_handler" target is implemented as follows:

• Define the target-specific CMake build configuration in the CMakeLists.txt file.
• Call the shared entry point functions that initialize, run and shut down CEF.
  • Uses the minimal target implementation.
• Implement the shared::Create*ProcessApp functions to create a CefApp instance appropriate to the process type.
  • Browser process: app_browser_impl.cc implements the shared::CreateBrowserProcessApp method.
    • Register the custom scheme name in OnRegisterCustomSchemes.
    • Register the custom scheme handler factory by calling RegisterSchemeHandlerFactory implemented in scheme_handler_impl.cc.
    • Create the initial CefBrowser instance.
  • Other processes: app_subprocess_impl.cc implements the shared::CreateRendererProcessApp and shared::CreateOtherProcessApp methods.
    • Register the custom scheme name in OnRegisterCustomSchemes.
• Provide a concrete CefClient implementation to handle CefBrowser callbacks.
  • Uses the minimal target implementation.
• Windows resource loading implementation in resource_util_win_impl.cc and resource.rc.
  • Implements the shared::GetResourceId method to map resource paths to BINARY ID values.
  • Defines a BINARY resource to include logo.png and scheme_handler.html in the executable.
