Detailed Description

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.

Member Function Documentation

◆ GetPdfPaperSize()

virtual CefSize CefPrintHandler::GetPdfPaperSize ( CefRefPtr< CefBrowser browser,
int  device_units_per_inch 
)
inlinevirtual

Return the PDF paper size in device units.

Used in combination with CefBrowserHost::PrintToPDF().

◆ OnPrintDialog()

virtual bool CefPrintHandler::OnPrintDialog ( CefRefPtr< CefBrowser browser,
bool  has_selection,
CefRefPtr< CefPrintDialogCallback callback 
)
pure virtual

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()

virtual bool CefPrintHandler::OnPrintJob ( CefRefPtr< CefBrowser browser,
const CefString document_name,
const CefString pdf_file_path,
CefRefPtr< CefPrintJobCallback callback 
)
pure virtual

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()

virtual void CefPrintHandler::OnPrintReset ( CefRefPtr< CefBrowser browser)
pure virtual

Reset client state related to printing.

◆ OnPrintSettings()

virtual void CefPrintHandler::OnPrintSettings ( CefRefPtr< CefBrowser browser,
CefRefPtr< CefPrintSettings settings,
bool  get_defaults 
)
pure virtual

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()

virtual void CefPrintHandler::OnPrintStart ( CefRefPtr< CefBrowser browser)
pure virtual

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).
