BrowserWindow
# ABOUT
This example uses
TLazarusBrowserWindow
TCEFWorkScheduler
TCEFWorkScheduler feeds the CEF messageloop by calling DoMessageLoopWork(). On Mac this is currently the only way to run the CEF messageloop.
# SETUP
** Windows
1) Download the CEF framework and place the content of the "Release" folder into the same folder as your exe.
Alternatively you can point "GlobalCEFApp.FrameworkDirPath" to the location with the libraries.
2) Run the project
** Linux
1) Download the CEF framework and place the content of the "Release" folder into the same folder as your exe.
Alternatively you can point "GlobalCEFApp.FrameworkDirPath" to the location with the libraries.
2) Run the project
Note:
- For your own Linux project you must modify the project source (lpr) and add "InitSubProcess" to the "uses" clause, so that it is in the list *before* the unit "Interfaces".
- The call to "DestroyGlobalCEFApp" must be in a unit *not* used by "unit InitSubProcess" (including not used in any nested way).
** Mac
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", create App Bundle and compile the AppHelper.
Run create_mac_helper.sh
4) Open project ExternalPumpBrowser, compile and run

// 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.
