class CefPrintHandler

extends CefBaseRefCounted

Implement this interface to handle printing on Linux. Each browser will have only one print job in progress at a time. The methods of this class will be called on the browser process UI thread.

GetPdfPaperSize

public virtual CefSize GetPdfPaperSize( int device_units_per_inch );

Return the PDF paper size in device units. Used in combination with CefBrowserHost::PrintToPDF().

OnPrintDialog

public virtual bool OnPrintDialog( CefRefPtr< CefBrowser > browser, bool has_selection, CefRefPtr< CefPrintDialogCallback > callback )= 0;

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

public virtual bool OnPrintJob( CefRefPtr< CefBrowser > browser, const CefString& document_name, const CefString& pdf_file_path, CefRefPtr< CefPrintJobCallback > callback )= 0;

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

public virtual void OnPrintReset( CefRefPtr< CefBrowser > browser )= 0;

Reset client state related to printing.

OnPrintSettings

public virtual void OnPrintSettings( CefRefPtr< CefBrowser > browser, CefRefPtr< CefPrintSettings > settings, bool get_defaults )= 0;

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.

OnPrintStart

public virtual void OnPrintStart( CefRefPtr< CefBrowser > browser )= 0;

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. CefBrowserHost::Print(), JavaScript window.print() or PDF extension print button).
