Struct gtk4::PageSetup [−][src]
pub struct PageSetup(_);Expand description
A PageSetup object stores the page size, orientation and margins.
The idea is that you can get one of these from the page setup dialog
and then pass it to the PrintOperation when printing.
The benefit of splitting this out of the PrintSettings is that
these affect the actual layout of the page, and thus need to be set
long before user prints.
Margins
The margins specified in this object are the “print margins”, i.e. the parts of the page that the printer cannot print on. These are different from the layout margins that a word processor uses; they are typically used to determine the minimal size for the layout margins.
To obtain a PageSetup use new() to get the defaults,
or use print_run_page_setup_dialog() to show the page setup dialog
and receive the resulting page setup.
A page setup dialog
⚠️ The following code is in c ⚠️
static GtkPrintSettings *settings = NULL;
static GtkPageSetup *page_setup = NULL;
static void
do_page_setup (void)
{
GtkPageSetup *new_page_setup;
if (settings == NULL)
settings = gtk_print_settings_new ();
new_page_setup = gtk_print_run_page_setup_dialog (GTK_WINDOW (main_window),
page_setup, settings);
if (page_setup)
g_object_unref (page_setup);
page_setup = new_page_setup;

Implementations
Desrialize a page setup from an a{sv} variant.
The variant must be in the format produced by
to_gvariant().
variant
an a{sv} GVariant
Returns
a new PageSetup object
Reads the page setup from the group group_name in the key file
key_file.
Returns a new PageSetup object with the restored
page setup, or None if an error occurred.
key_file
the GKeyFile to retrieve the page_setup from
group_name
the name of the group in the key_file to read to use the default name “Page Setup”
Returns
the restored PageSetup
Returns the page height in units of unit.
Note that this function takes orientation
and margins into consideration.
See paper_height().
unit
the unit for the return value
Returns
the page height.
Returns the page width in units of unit.

and margins into consideration.
See paper_width().
unit
the unit for the return value
Returns
the page width.
Returns the paper height in units of unit.
Note that this function takes orientation,
but not margins into consideration.

unit
the unit for the return value
Returns
the paper width.
Reads the page setup from the group group_name in the key file
key_file.
key_file
the GKeyFile to retrieve the page_setup from
group_name
the name of the group in the key_file to read to use the default name “Page Setup”
Returns
true on success
Sets the paper size of the PageSetup without
changing the margins.
See set_paper_size_and_default_margins().
size
This function adds the page setup from self to key_file.
key_file
the GKeyFile to save the page setup to
group_name
the group to add the settings to in key_file,
or None to use the default name “Page Setup”
