Struct gtk::PrintSettings [−][src]
pub struct PrintSettings(_);
Expand description
A GtkPrintSettings object represents the settings of a print dialog in a system-independent way. The main use for this object is that once you’ve printed you can get a settings object that represents the settings the user chose, and the next time you print you can pass that object in so that the user doesn’t have to re-set all his settings.
Its also possible to enumerate the settings so that you can easily save the settings for the next time your app runs, or even store them in a document. The predefined keys try to use shared values as much as possible so that moving such a document between systems still works.
Printing support was added in GTK+ 2.10.

Reads the print settings from file_name. Returns a new PrintSettings
object with the restored settings, or None if an error occurred. If the
file could not be loaded then error is set to either a GFileError or
GKeyFileError. See to_file().

) -> Result<PrintSettings, Error>
pub fn from_key_file(
key_file: &KeyFile,
group_name: Option<&str>
) -> Result<PrintSettings, Error>Reads the print settings from the group group_name in key_file. Returns a
new PrintSettings object with the restored settings, or None if an
error occurred. If the file could not be loaded then error is set to either
a GFileError or GKeyFileError.
key_file

group_name

the default “Print Settings”
Returns
the restored PrintSettings
Returns the floating point number represented by
the value that is associated with key, or default_val
if the value does not represent a floating point number.
Floating point numbers are parsed with g_ascii_strtod().
key

Returns
the media type
Get the value of PRINT_SETTINGS_ORIENTATION,
converted to a PageOrientation.
Returns
the orientation
Gets the value of PRINT_SETTINGS_PAGE_RANGES.
Returns
an array
of GtkPageRanges. Use g_free() to free the array when
it is no longer needed.
Gets the value of PRINT_SETTINGS_PAPER_HEIGHT,
converted to unit.
unit
the unit for the return value
Returns
the paper height, in units of unit
Gets the value of PRINT_SETTINGS_PAPER_WIDTH,
converted to unit.
unit
the unit for the return value
Returns
the paper width, in units of unit
Reads the print settings from the group group_name in key_file. If the
file could not be loaded then error is set to either a GFileError or
GKeyFileError.
key_file
the glib::KeyFile to retrieve the settings from
group_name
the name of the group to use, or None to use the default
“Print Settings”
Returns
true on success
Sets the value of PRINT_SETTINGS_MEDIA_TYPE.
The set of media types is defined in PWG 5101.1-2002 PWG.
media_type
the media type
Sets the value of PRINT_SETTINGS_PAPER_FORMAT,
PRINT_SETTINGS_PAPER_WIDTH and
PRINT_SETTINGS_PAPER_HEIGHT.
paper_size
a paper size
Sets the values of PRINT_SETTINGS_RESOLUTION,
PRINT_SETTINGS_RESOLUTION_X and
PRINT_SETTINGS_RESOLUTION_Y.
resolution
the resolution in dpi
Sets the values of PRINT_SETTINGS_RESOLUTION,
PRINT_SETTINGS_RESOLUTION_X and
PRINT_SETTINGS_RESOLUTION_Y.
resolution_x
the horizontal resolution in dpi
resolution_y
the vertical resolution in dpi
This is supported on crate feature v3_22 only.
v3_22 only.This function adds the print settings from self to key_file.
key_file
the glib::KeyFile to save the print settings to
group_name
the group to add the settings to in key_file, or
None to use the default “Print Settings”
