Method Detail

doClose

public boolean doClose(CefBrowser browser)

Description copied from interface: CefLifeSpanHandler

Called when a browser has received a request to close. If CEF created an OS window for the browser returning false will send an OS close notification to the browser window's top-level owner (e.g. WM_CLOSE on Windows, performClose: on OS-X and "delete_event" on Linux). If no OS window exists (window rendering disabled) returning false will cause the browser object to be destroyed immediately. Return true if the browser is parented to another window and that other window needs to receive close notification via some non-standard technique.

Specified by:

doClose in interface CefLifeSpanHandler

Parameters:

browser - The browser generating the event.

Returns:

False to send an OS close notification to the browser window's top-level owner.

onBeforeClose

public void onBeforeClose(CefBrowser browser)

Description copied from interface: CefLifeSpanHandler

Called just before a browser is destroyed. Release all references to the browser object and do not attempt to execute any methods on the browser object after this callback returns. If this is a modal window and a custom modal loop implementation was provided in runModal() this callback should be used to exit the custom modal loop. See doClose() documentation for additional usage information.
