Popups

  1. window.open('wxpython.html')
  2. target=_blank href="wxpython.html"

CreateAnotherBrowser

This will create a window on its own and embed browser in it. When using "window.open" the window is created implicitilly by CEF. You can intercept such popup creation using the OnBeforePopup callback in LifespanHandler. You can return True in OnBeforePopup and create popup window on your own using the CreateAnotherBrowser function. external.CreateAnotherBrowser()

HTML5 video and accelerated content

HTML 5 video
Accelerated canvas
Accelerated layers

Developer Tools

You can open devtools popup window in a few different ways:
  1. Call Browser.ShowDevTools() method: external.ShowDevTools()
  2. Through mouse context menu
  3. Through F12 key (on Mac: Cmd+Opt+I) which is handled in KeyboardHandler.OnKeyEvent.

Downloads

Download sample Ubuntu wallpapers:
https://cefpython.googlecode.com/files/ubuntu-wallpapers2.zip

Notes: On Linux it seems that OnLoadError with errorCode = ERR_ABORTED is called even for successful downloads, you can ignore this behavior. The proper console messages about successful/aborted download originate from C++ Browser process code, these are: 

Browser: About to download file: ubuntu-wallpapers2.zip
Browser: Download completed, saved to: /Downloads/ubuntu-wallpapers2.zip
If download was aborted the messages will be: 
Browser: About to download file: ubuntu-wallpapers2.zip
Browser: Download was cancelled

Additionally on Linux there are more errors reported by Chromium about org.gnome.SessionManager.inhibit. These can be safely ignored as well.

A download handler with callbacks like `OnBeforeDownload` and `OnDownloadUpdated` may be exposed to CEF Python in the future.

function DoRequestQuota() {
    // Request Quota (only for File System API)
    try {
        navigator.webkitPersistentStorage.requestQuota(PERSISTENT, 1024*1024,
                function(bytes){ window.alert("Granted bytes: "+bytes);},
                function(error){ window.alert(error); });
    } catch(e) {
        navigator.webkitPersistentStorage.requestQuota(1024*1024,

https://tv.eurosport.com/

OnRendererProcessTerminated

Try to terminate the "subprocess.exe" renderer process through task manager.

OnPluginCrashed

No test for that yet.

Cookie tests

See messages in the console.

GetCookieManager

RequestHandler.GetCookieManager() - an example of having an unique cookie manager for each browser.
  1. Visit the url below and set some cookies. Use "Back" from context menu to get back here (you might have to click "Back" multiple times).
    Visit it in the current browser:
    http://www.html-kit.com/tools/cookietester/
    Or visit it in a js popup:
    javascript:window.open('http://www.html-kit.com/tools/cookietester/')
  2. Open cookietester in a popup:
    javascript:external.CreateAnotherBrowser('http://www.html-kit.com/tools/cookietester/')

Popup browsers created javascript's window.open share the same renderer process and request context. If you want to have separate cookie managers for popups created using window.open then you have to implement the LifespanHandler.`OnBeforePopup` callback. Return True in that callback to cancel popup creation and instead create the window on your own and embed browser in it. The CreateAnotherBrowser() function from the wxpython example does that.

VisitAllCookies

Visit all cookies: external.VisitAllCookies()

Note: visit some http:// webpage first, otherwise cookie manager is not yet created.

VisitUrlCookies

Visit a subset of cookies for the given url: external.VisitUrlCookies("http://www.html-kit.com/tools/cookietester/")

SetCookie

Set a cookie: external.SetCookie()

DeleteCookies

Delete the single cookie previously created via SetCookie(): external.DeleteCookies()

Load Handler

See messages in the console during loading of a webpage.

OnLoadingStateChange

OnLoadStart

OnLoadEnd

OnLoadError

Try this: http://www.non-existent.nono/

Note: after you see the custom error message you have to hit twice the Back from the context menu, to get back to this page.

Javascript Dialog Handler

OnJavascriptDialog

alert('Test js dialog handler')

OnBeforeUnloadJavascriptDialog

<script>
function TestOnBeforeUnloadJavascriptDialog() {
    window.onbeforeunload = function() {
