ExternalPumpBrowser
# ABOUT
This example uses
TCEFLinkedWindowParent
TCEFWorkScheduler
TCEFWorkScheduler feeds the CEF messageloop by calling DoMessageLoopWork(). On Mac this is currently the only way to run the CEF messageloop.
# SETUP
1) Go to "project options" and create the "App Bundle"
2) Download the CEF framework and place the content of the "Release" folder into ExternalPumpBrowser.app/Contents/Frameworks/Chromium Embedded Framework.framework
You should have:
Chromium Embedded Framework
Libraries/*
Resources/*
3) Open project "AppHelper" (from demos/Lazarus_any_OS ), create App Bundle and compile the AppHelper.
Run create_mac_helper.sh
4) Open project ExternalPumpBrowser, compile and run

// This is a demo with the simplest web browser you can build using CEF4Delphi and
// it doesn't show any sign of progress like other web browsers do.
// Remember that it may take a few seconds to load if Windows update, your antivirus or
// any other windows service is using your hard drive.
// Depending on your internet connection it may take longer than expected.
// Please check that your firewall or antivirus are not blocking this application
// or the domain "google.com". If you don't live in the US, you'll be redirected to
// another domain which will take a little time too.
// This demo uses a TChromium and a TCEFLinkedWindowParent
// We need to use TCEFLinkedWindowParent in Linux to update the browser
// visibility and size automatically.
// Destruction steps
// =================
// 1. FormCloseQuery sets CanClose to FALSE calls TChromium.CloseBrowser which triggers the TChromium.OnClose event.
// 2. TChromium.OnClose sets aAction to cbaClose to destroy the browser, which triggers the TChromium.OnBeforeClose event.
// 3. TChromium.OnBeforeClose sets FCanClose := True and sends CEF_BEFORECLOSE to close the form.
