方法详细资料

onBeforeCommandLineProcessing

public void onBeforeCommandLineProcessing(String process_type,
                                 CefCommandLine command_line)

从接口复制的说明: CefAppHandler

Provides an opportunity to view and/or modify command-line arguments before processing by CEF and Chromium. The |process_type| value will be empty for the browser process. Be cautious when using this method to modify command-line arguments for non-browser processes as this may result in undefined behavior including crashes.

指定者:

onBeforeCommandLineProcessing 在接口中 CefAppHandler

参数:

process_type - type of process (empty for browser process).

command_line - values of the command line.

stateHasChanged

public void stateHasChanged(CefApp.CefAppState state)

从接口复制的说明: CefAppHandler

Implement this method to get state changes of the CefApp. See CefApp.CefAppState for a complete list of possible states. For example, this method can be used e.g. to get informed if CefApp has completed its initialization or its shutdown process.

指定者:

stateHasChanged 在接口中 CefAppHandler

参数:

state - The current state of CefApp.

onBeforeTerminate

public boolean onBeforeTerminate()

从接口复制的说明: CefAppHandler

Provides an opportunity to hook into the native shutdown process. This method is invoked if the user tries to terminate the app by sending the corresponding key code (e.g. on Mac: CMD+Q) or something similar. If you want to proceed with the default behavior of the native system, return false. If you want to abort the terminate or if you want to implement your own shutdown sequence return true and do the cleanup on your own.

指定者:

onBeforeTerminate 在接口中 CefAppHandler

返回:

false to proceed with the default behavior, true to abort terminate

onRegisterCustomSchemes

public void onRegisterCustomSchemes(CefSchemeRegistrar registrar)

从接口复制的说明: CefAppHandler

Provides an opportunity to register custom schemes. Do not keep a reference to the |registrar| object. This method is called on the main thread for each process and the registered schemes should be the same across all processes.

指定者:

onRegisterCustomSchemes 在接口中 CefAppHandler

onContextInitialized

public void onContextInitialized()

从接口复制的说明: CefAppHandler

Called on the browser process UI thread immediately after the CEF context has been initialized.

指定者:

onContextInitialized 在接口中 CefAppHandler

getPrintHandler

public CefPrintHandler getPrintHandler()

从接口复制的说明: CefAppHandler

Return the handler for printing on Linux. If a print handler is not provided then printing will not be supported on the Linux platform.

指定者:

getPrintHandler 在接口中 CefAppHandler

返回:

a reference to a print handler implementation
