// This is a simple demo showing how to load, unload and show the popup page
// from a chrome extension.
// This demo only allows to load the extension once.
// The extension loaded is called "Hello World" and it's located in the
// CEF4Delphi\bin\hello directory. It only has a browser action popup html with
// the "Hello World" message and no other functionality.
// It's necessary to unload the extension before you close the form. Notice that
// both TChromium components must be properly destroyed before allowing the form
// to close.
// This demo is just a template for other demos and it has a browser loading
// google.com but in this case the extension doesn't use that browser.
// Load chrome://extensions-support/ to get a list of supported APIs
// Destruction steps
// =================
// 1. FormCloseQuery sets CanClose to FALSE calls TChromium.CloseBrowser in both
// browsers which triggers the TChromium.OnClose event.
// 2. TChromium.OnClose sends a CEFBROWSER_DESTROY message to destroy
// CEFWindowParent1 and CEFWindowParent2 in the main thread, which triggers
// the TChromium.OnBeforeClose event.
// 3. TChromium.OnBeforeClose sets FCanClose := True and sends WM_CLOSE to the form.

// This demo shows how to load an extension that modifies the background color
// of the active browser.
// This demo only allows to load the extension once.
// The extension loaded is called "Set Page Color" and it's located in the
// CEF4Delphi\bin\set_page_color directory. It only has a browser action popup
// html that allows you to select the page background color.
// It's necessary to unload the extension before you close the form. Notice that
// both TChromium components must be properly destroyed before allowing the form
// to close.
// Load chrome://extensions-support/ to get a list of supported APIs
// Destruction steps
// =================
// 1. FormCloseQuery sets CanClose to FALSE calls TChromium.CloseBrowser in both
// browsers which triggers the TChromium.OnClose event.
// 2. TChromium.OnClose sends a CEFBROWSER_DESTROY message to destroy
// CEFWindowParent1 and CEFWindowParent2 in the main thread, which triggers
// the TChromium.OnBeforeClose event.
// 3. TChromium.OnBeforeClose sets FCanClose := True and sends WM_CLOSE to the form.
