Method Detail

initialize

public void initialize()

Description copied from interface: Cef

Initialize CEF. Only use this method directly when running the message loop manually, i.e. via Cef.doMessageLoopWork(). Must be called from the main application thread (see CEF documentation on CefInitialize).

Specified by:

initialize in interface Cef

start

public java.util.concurrent.CompletableFuture<java.lang.Void> start()

Description copied from interface: Cef

Start CEF and run the automatic message loop. A new thread will be started which initializes CEF and then runs the CEF message loop (see CefRunMessageLoop). When using this method, Cef.initialize() must not be invoked manually as it will be handled by the implementation to ensure it happens on the correct thread.

Specified by:

start in interface Cef

Returns:

a CompletableFuture which completes when CEF has been initialized. Can be used to determine the status as alternative to polling Cef.isInitialized().

doMessageLoopWork

public void doMessageLoopWork()

Description copied from interface: Cef

Perform a single iteration of CEF message loop processing. Can be used to integrate the CEF message loop into an existing message loop. CEF must be initialized manually via Cef.initialize() beforehand. Must be called from the main application thread (see CEF documentation on CefDoMessageLoopWork). Note that care needs to be taken to neither call this too infrequently (to avoid starving the CEF message loop) but also not too often (to avoid impacting CPU usage) - see CEF documentation for details when using this approach.

Specified by:

doMessageLoopWork in interface Cef

shutdown

public void shutdown()
              throws java.lang.InterruptedException

Description copied from interface: Cef

Shutdown CEF processes, should be called before the application exits. When operating using a manual message loop via Cef.doMessageLoopWork(), this must be called from the main application thread (see CEF documentation on CefShutdown). When using the integrated/automatic message loop it may be invoked from any thread as the implementation ensures the shutdown is run on the correct thread.

Specified by:

shutdown in interface Cef

Throws:

java.lang.InterruptedException - if the current thread is interrupted whilst waiting on the shutdown of the integrated message loop

isInitialized

public boolean isInitialized()

Specified by:

isInitialized in interface Cef

ensureInitialized

protected void ensureInitialized()

createBrowser

public Browser createBrowser(RenderHandler renderHandler,
                             java.net.URL initialURL)

Description copied from interface: Cef

Create a new browser.

Specified by:

createBrowser in interface Cef

Parameters:

renderHandler - handler which provides viewport information and renders images

initialURL - the initial URL to load in the created browser

Returns:

a new browser instance
