方法详细资料

onPrintStart

void onPrintStart(CefBrowser browser)

Called when printing has started for the specified |browser|. This method will be called before the other onPrint*() methods and irrespective of how printing was initiated (e.g. CefBrowser::print(), JavaScript window.print() or PDF extension print button).

onPrintSettings

void onPrintSettings(CefPrintSettings settings,
                   boolean get_defaults)

Synchronize |settings| with client state. If |get_defaults| is true then populate |settings| with the default print settings. Do not keep a reference to |settings| outside of this callback.

onPrintDialog

boolean onPrintDialog(boolean has_selection,
                    CefPrintDialogCallback callback)

Show the print dialog. Execute |callback| once the dialog is dismissed. Return true if the dialog will be displayed or false to cancel the printing immediately.

onPrintJob

boolean onPrintJob(String document_name,
                 String pdf_file_path,
                 CefPrintJobCallback callback)

Send the print job to the printer. Execute |callback| once the job is completed. Return true if the job will proceed or false to cancel the job immediately.

onPrintReset

void onPrintReset()

Reset client state related to printing.
