## Description

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;
    }

                                                 GtkSourceBuffer *buffer);

Creates a new print job to print `buffer`.

`config` : | an optional GnomePrintConfig.
`buffer` : | the GtkSourceBuffer to print (might be NULL).
Returns : | a new print job object.

### gtk_source_print_job_set_config ()

    void        gtk_source_print_job_set_config (GtkSourcePrintJob *job,
                                                 GnomePrintConfig *config);

Sets the print configuration for the job. If you don't set a configuration object for the print job, when needed one will be created with `gnome_print_config_default()`.

### gtk_source_print_job_get_numbers_font ()

    gchar*      gtk_source_print_job_get_numbers_font
                                                (GtkSourcePrintJob *job);

Determines the font to be used for the line numbers. The returned string is of the form "Fontfamily Style Size", for example "Monospace Regular 10.0". The returned value should be freed when no longer needed. This function might return NULL if a specific font for numbers has not been set.

`job` : | a GtkSourcePrintJob.
Returns : | a newly allocated string with the name of the current line numbers font, or NULL.

### gtk_source_print_job_set_print_numbers ()

    void        gtk_source_print_job_set_print_numbers
                                                (GtkSourcePrintJob *job,

Sets the interval for printed line numbers. If `interval` is 0 no numbers will be printed. If greater than 0, a number will be printed every `interval` lines (i.e. 1 will print all line numbers).

`job` : | a GtkSourcePrintJob.
`interval` : | interval for printed line numbers.

### gtk_source_print_job_get_print_numbers ()

    guint       gtk_source_print_job_get_print_numbers
                                                (GtkSourcePrintJob *job);

`job` : | a GtkSourcePrintJob.
Returns : | the interval of printed line numbers.

### gtk_source_print_job_set_text_margins ()

    void        gtk_source_print_job_set_text_margins
                                                (GtkSourcePrintJob *job,
                                                 gdouble top,
                                                 gdouble bottom,

                                                 gdouble right);

Sets the four user margins for the print job. These margins are in addition to the document margins provided in the GnomePrintConfig and will not be used for headers, footers or line numbers (those are calculated separatedly). You can print in the space allocated by these margins by connecting to the "begin_page" signal. The space is around the printed text, and inside the margins specified in the GnomePrintConfig.

The margin numbers are given in device units. If any of the given values is less than 0, that particular margin is not altered by this function.

`job` : | a GtkSourcePrintJob.
`top` : | the top user margin.
`bottom` : | the bottom user margin.
`left` : | the left user margin.
`right` : | the right user margin.

### gtk_source_print_job_get_text_margins ()

    void        gtk_source_print_job_get_text_margins
                                                (GtkSourcePrintJob *job,

                                                 gdouble *left,
                                                 gdouble *right);

Determine the user set margins for the job. This function retrieves the values previously set by `gtk_source_print_job_set_text_margins()`. The default for all four margins is 0. Any of the pointers can be NULL if you want to ignore that value.

`job` : | a GtkSourcePrintJob.
`top` : | a pointer to a gdouble to return the top margin.
`bottom` : | a pointer to a gdouble to return the bottom margin.
`left` : | a pointer to a gdouble to return the left margin.
`right` : | a pointer to a gdouble to return the right margin.

### gtk_source_print_job_print ()

    GnomePrintJob* gtk_source_print_job_print   (GtkSourcePrintJob *job);

Produces a GnomePrintJob with the printed document. The whole contents of the configured GtkSourceBuffer are printed. The returned job is already closed and ready to be previewed (using `gnome_print_job_preview_new()`) or printed directly. The caller of this function owns a reference to the returned object, so `job` can be destroyed and the output will still be valid, or the document can be printed again with different settings.

`job` : | a configured GtkSourcePrintJob.
Returns : | a closed GnomePrintJob with the printed document, or NULL if printing could not be completed.

### gtk_source_print_job_print_range ()

    GnomePrintJob* gtk_source_print_job_print_range
                                                (GtkSourcePrintJob *job,
                                                 const GtkTextIter *start,
                                                 const GtkTextIter *end);

Similar to `gtk_source_print_job_print()`, except you can specify a range of text to print. The passed GtkTextIter values might be out of order.

`job` : | a configured GtkSourcePrintJob.
`start` : | the start of the region of text to print.
`end` : | the end of the region of text to print.
Returns : | a closed GnomePrintJob with the text from `start` to `end` printed, or NULL if `job` could not print.

### gtk_source_print_job_print_range_async ()

    gboolean    gtk_source_print_job_print_range_async
                                                (GtkSourcePrintJob *job,
                                                 const GtkTextIter *start,
                                                 const GtkTextIter *end);

Starts to print `job` asynchronously. This function will ready the `job` for printing and install an idle handler that will render one page at a time.

This function will not return immediatly, as only page rendering is done asynchronously. Text retrieval and paginating happens within this function. Also, if highlighting is enabled, the whole buffer needs to be highlighted first.

To get notification when the job has finished, you must connect to the "finished" signal. After this signal is emitted you can retrieve the resulting GnomePrintJob with `gtk_source_print_job_get_print_job()`. You may cancel the job with `gtk_source_print_job_cancel()`.

`job` : | a configured GtkSourcePrintJob.
`start` : | the start of the region of text to print.
`end` : | the end of the region of text to print.
Returns : | TRUE if the print started.

### gtk_source_print_job_cancel ()

    void        gtk_source_print_job_cancel     (GtkSourcePrintJob *job);

Cancels an asynchronous printing operation. This will remove any pending print idle handler and unref the current GnomePrintJob.

Note that if you got a reference to the job's GnomePrintJob (using `gtk_source_print_job_get_print_job()`) it will not be destroyed (since you hold a reference to it), but it will not be closed either. If you wish to show or print the partially printed document you need to close it yourself.

This function has no effect when called from a non-asynchronous print operation.

`job` : | a GtkSourcePrintJob.

### gtk_source_print_job_get_print_job ()

    GnomePrintJob* gtk_source_print_job_get_print_job
                                                (GtkSourcePrintJob *job);

Gets a reference to the GnomePrintJob which the `job` is printing or has recently finished printing. You need to unref the returned object.

You may call this function in the middle of an asynchronous printing operation, but the returned GnomePrintJob will not be closed until the last page is printed and the "finished" signal is emitted.

`job` : | a GtkSourcePrintJob.
Returns : | a new reference to the `job`'s GnomePrintJob, or NULL.

### gtk_source_print_job_get_page ()

    guint       gtk_source_print_job_get_page   (GtkSourcePrintJob *job);

Determines the currently printing page number. This function is only valid while printing (either synchronously or asynchronously).

`job` : | a GtkSourcePrintJob.
Returns : | the current page number.

### gtk_source_print_job_get_page_count ()

    guint       gtk_source_print_job_get_page_count
                                                (GtkSourcePrintJob *job);

Determines the total number of pages the job will print. The returned value is only meaninful after pagination has finished. In practice, for synchronous printing this means when "begin_page" is emitted, or after `gtk_source_print_job_print_range_async()` has returned.

`job` : | a GtkSourcePrintJob.
Returns : | the number of pages of the printed job.

### gtk_source_print_job_get_print_context ()

    GnomePrintContext* gtk_source_print_job_get_print_context
                                                (GtkSourcePrintJob *job);

Determines the GnomePrintContext of the current job. This function is only valid while printing. Normally you would use this function to print in the margins set by `gtk_source_print_job_set_margins()` in a handler for the "begin_page" signal.

`job` : | a printing GtkSourcePrintJob.
Returns : | the current GnomePrintContext. The returned object is owned by `job`.

### gtk_source_print_job_set_print_header ()

    void        gtk_source_print_job_set_print_header
                                                (GtkSourcePrintJob *job,
                                                 gboolean setting);

Sets whether you want to print a header in each page. The default header consists of three pieces of text and an optional line separator, configurable with `gtk_source_print_job_set_header_format()`.

Note that by default the header format is unspecified, and if it's empty it will not be printed, regardless of this setting.

`job` : | a GtkSourcePrintJob.
`setting` : | TRUE if you want the header to be printed.

### gtk_source_print_job_get_print_header ()

    gboolean    gtk_source_print_job_get_print_header
                                                (GtkSourcePrintJob *job);

Determines if a header is set to be printed for each page. A header will be printed if this function returns TRUE and some format strings have been specified with `gtk_source_print_job_set_header_format()`.

`job` : | a GtkSourcePrintJob.
Returns : | TRUE if the header is set to be printed.

### gtk_source_print_job_set_print_footer ()

    void        gtk_source_print_job_set_print_footer
                                                (GtkSourcePrintJob *job,
                                                 gboolean setting);

Sets whether you want to print a footer in each page. The default footer consists of three pieces of text and an optional line separator, configurable with `gtk_source_print_job_set_footer_format()`.

Note that by default the footer format is unspecified, and if it's empty it will not be printed, regardless of this setting.

`job` : | a GtkSourcePrintJob.
`setting` : | TRUE if you want the footer to be printed.

### gtk_source_print_job_get_print_footer ()

    gboolean    gtk_source_print_job_get_print_footer
                                                (GtkSourcePrintJob *job);

Determines if a footer is set to be printed for each page. A footer will be printed if this function returns TRUE and some format strings have been specified with `gtk_source_print_job_set_footer_format()`.

`job` : | a GtkSourcePrintJob.
Returns : | TRUE if the footer is set to be printed.

### gtk_source_print_job_set_header_footer_font ()

    void        gtk_source_print_job_set_header_footer_font
                                                (GtkSourcePrintJob *job,
                                                 const gchar *font_name);

Sets the font for printing headers and footers. If NULL is supplied, the default font (i.e. the one being used for the text) will be used instead.

`job` : | a GtkSourcePrintJob.
`font_name` : | the full name of the font to be used in headers and footers, or NULL.

### gtk_source_print_job_get_header_footer_font ()

    gchar*      gtk_source_print_job_get_header_footer_font
                                                (GtkSourcePrintJob *job);

Determines the font to be used for the header and footer. The returned string is of the form "Fontfamily Style Size", for example "Monospace Regular 10.0". The returned value should be freed when no longer needed. This function might return NULL if a specific font has not been set.

`job` : | a GtkSourcePrintJob.
Returns : | a newly allocated string with the name of the current header and footer font, or NULL.

### gtk_source_print_job_set_header_format ()

    void        gtk_source_print_job_set_header_format
                                                (GtkSourcePrintJob *job,
                                                 const gchar *left,

                                                 gboolean separator);

Sets strftime like header format strings, to be printed on the left, center and right of the top of each page. The strings may include strftime(3) codes which will be expanded at print time. All `strftime()` codes are accepted, with the addition of `N` for the page number and `Q` for the page count.

`separator` specifies if a solid line should be drawn to separate the header from the document text.

If NULL is given for any of the three arguments, that particular string will not be printed. For the header to be printed, in addition to specifying format strings, you need to enable header printing with `gtk_source_print_job_set_print_header()`.

`job` : | a GtkSourcePrintJob.
`left` : | a format string to print on the left of the header.
`center` : | a format string to print on the center of the header.

## Signals

### The "begin-page" signal

    void        user_function                  (GtkSourcePrintJob *sourceprintjob,
                                                gpointer user_data);

Emitted whenever the `sourceprintjob` is about to print a new text page. You can connect to this signal to provide the user with feedback about the progress of printing, or to customize the printed page by for example, printing your own headers and footers.

`sourceprintjob` : | the object which received the signal.
`user_data` : | user data set when the signal handler was connected.

### The "finished" signal

    void        user_function                  (GtkSourcePrintJob *sourceprintjob,
                                                gpointer user_data);

Emitted whenever an asynchronous print job has finished. You can connect to this signal to get notification when a job has finished printing. When it's emitted, the GnomePrintJob the `sourceprintjob` was producing has been closed and it can be either previewed or printed to the physical device.

`sourceprintjob` : | the object which received the signal.
`user_data` : | user data set when the signal handler was connected.
