GtkSourcePrintJob Printing a #GtkSourceBuffer. The #GtkSourcePrintJob object is used to print the contents of a #GtkSourceBuffer. You can set various configuration options to customize the printed output, and the result is obtained as a #GnomePrintJob object, which you can then preview with gnome_print_job_preview_new() or print directly with gnome_print_job_print(). Printing can be done synchronously and asynchronously. Asynchronous methods are provided so you can give the user feedback about what's going on when printing long documents (see the "begin_page" and "finished" signals). The task of a #GtkSourcePrintJob is to produce a #GnomePrintJob. What this means is that once you get the resulting #GnomePrintJob, you might reuse the #GtkSourcePrintJob to produce another output (with different configuration options for example) or just unreference it and forget about it. The lifetime of the produced object is independent of that of the producer. Before printing you should at least set the #GtkSourceBuffer you want to print (using gtk_source_print_job_set_buffer ()). Besides that, you might configure word wrapping, font, whether to print hightlighted text as seen in the #GtkSourceView, line numbers, basic headers and footers. #GtkSourcePrintJob can print basic headers and footers in each page. You can specify strftime() like strings for text on the left, right and center of the top and bottom of the page. You can also make #GtkSourcePrintJob draw a separator line between the text document and the header and footer. And you can specify a different font (from that used for the text document). Customization beyond that is possible, but you have to do the printing manually. To do that, you need to connect to the "begin_page" signal of the job and allocate some space in the page using gtk_source_print_job_set_text_margins(). Whenever #GtkSourcePrintJob is about to print a new text page, the signal will be emitted. You can then get the #GnomePrintContext being used with gtk_source_print_job_get_print_context() and use Gnome Print functions directly. The space you allocate is inside the document margins defined in the specified #GnomePrintConfig, but outside all print area used by #GtkSourcePrintJob itself. A quick bootstrap code sequence to get you started using #GtkSourcePrintJob is given below: static GnomePrintJob * print_source_buffer_from_view (GtkSourceView *view, const gchar *title) { GtkSourcePrintJob *job; GnomePrintJob *print_job; /* create the job using default print configuration */ job = gtk_source_print_job_new (NULL); /* quickly setup the buffer, font and wrapping */ gtk_source_print_job_setup_from_view (job, view); /* print line numbers every 5 lines, using default font */ gtk_source_print_job_set_print_numbers (job, 5); /* print a header with the title centered */ gtk_source_print_job_set_header_footer_font (job, "Sans Regular 12.0"); gtk_source_print_job_set_header_format (job, NULL, title, NULL, TRUE); gtk_source_print_job_set_print_header (job, TRUE); /* print the page number in the page bottom */ gtk_source_print_job_set_footer_format (job, NULL, NULL, "Page %N of %Q", TRUE); gtk_source_print_job_set_print_footer (job, TRUE); /* print the whole buffer and return the result */ print_job = gtk_source_print_job_print (job); /* job is no longer needed */ g_object_unref (job); return print_job; } The reference documentation for #GtkSourceBuffer.
