GtkPrintOperation file name

[Cristian.G (Cristian Gyorgy)]

Hi,
How can I change the print file name in the Gtk print dialog?
To better understand my needs, in a GtkNotebook, every tab has a name identifier and can be printed out independently. I want to add the respective identifier in the print output file name (print to file, pdf.), the “~/Documents/output.pdf” in the attached capture.
I use the GtkPrintOperation API in C, linux.
I do not want to use gtk_print_operation_set_export_filename(), to keep the option of normal printing.

Thank you!

Use GtkPrintSettings to set the output file details:

gtk_print_settings_set (settings,
  GTK_PRINT_SETTINGS_OUTPUT_BASENAME,
  "output-file-basename");
gtk_print_settings_set (settings,
  GTK_PRINT_SETTINGS_OUTPUT_FILE_FORMAT,
  "pdf");
gtk_print_settings_set (settings,
  GTK_PRINT_SETTINGS_OUTPUT_DIR,
  some_directory);

Great! Many thanks!
Sorry if I missed these items in the help pages, but I couldn’t find directly the keys for the gtk_print_settings_set() function.

They are part of the API reference, for instance:

• GTK_PRINT_SETTINGS_OUTPUT_BASENAME
• GTK_PRINT_SETTINGS_OUTPUT_FILE_FORMAT

You can search for “print settings output” in the documentation, for instance. They are also listed in the “constants” section of the main index.
