The current default implementation for Windows * display a native print dialog but a XUL-based progress dialog. * If you wish to have a native progress dialog on Windows you will have to create and * register your own service. * * Note: The Windows version Mozilla implements this service which is * automatically built and registered for you. You can use it as an example. * It is located at "mozilla/embedding/components/printingui/src/win". That service * is capable of displaying a native print dialog and a XUL progress dialog. * * To fly your own dialog you may: * * 1) Implement this service to display at least the Print Dialog and a Print Progress Dialog * or you may implement just one of the dialogs and pass back NS_ERROR_NOT_IMPLEMENTED * for any of the others. * * 2) For the Print Dialog: * You may stub out this service by having all the methods return NS_ERROR_NOT_IMPLEMENTED. * You can then fly you own dialog and then properly fill in the PrintSettings object * before calling nsIWebBrowserPrint's Print method. If you stub out this service * you MUST set "printSilent" to true, if you do not, Printing will terminate and an * error dialog will be displayed. * * Mac: The GFX layer still supports default toolkit behavior for displaying the Print Dialog. * If an embedder implemented service returns NS_ERROR_NOT_IMPLEMENTED for "showPrintDialog" * The toolkit will display the native print dialog. * * Defaults for platform service: * Mac OS9: showPrintDialog - displays a native dialog * showPageSetup - displays a native dialog * showProgress - displays a XUL dialog * showPrinterProperties - n/a * * Mac OSX: showPrintDialog - displays a native dialog * showPageSetup - displays a native dialog * showProgress - not implemented (provided by OS) * showPrinterProperties - n/a * * GTK: There are no native dialog for GTK. * * Defaults for platform service: * showPrintDialog - displays a XUL dialog * showPageSetup - displays a XUL dialog * showProgress - displays a XUL dialog * showPrinterProperties - displays a XUL dialog * */ /** * Show the Print Dialog * * @param webBrowserPrint - represents the document to be printed * @param printSettings - PrintSettings for print "job" * */ void showPrintDialog(in nsIWebBrowserPrint webBrowserPrint, in nsIPrintSettings printSettings); /** * Shows the print progress dialog * * @param webBrowserPrint - represents the document to be printed * @param printSettings - PrintSettings for print "job" * @param openDialogObserver - an observer that will be notifed when the dialog is opened * @param isForPrinting - true - for printing, false for print preview * @param webProgressListener - additional listener can be registered for progress notifications * @param printProgressParams - parameter object for passing progress state * @param notifyOnOpen - this indicates that the observer will be notified when the progress * dialog has been opened.
