Struct gtk4::PrintSettings [−][src]
pub struct PrintSettings(_);
Expand description
A PrintSettings
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.

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()
.
file_name
the filename to read the settings from
Returns
the restored PrintSettings
Deserialize print settings from an a{sv} variant.
The variant must be in the format produced by
to_gvariant()
.
variant
an a{sv} GVariant
Returns
a new PrintSettings
object

group_name: Option<&str>
) -> 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 GFileError
or GKeyFileError
.
key_file
the GKeyFile
to retrieve the settings from
group_name
the name of the group to use, or None
to use
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
a key
def
the default value
Returns
the floating point number associated with key
Gets the value of PRINT_SETTINGS_MEDIA_TYPE
.
The set of media types is defined in PWG 5101.1-2002 PWG.
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 PageRange
s. 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 GKeyFile
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 function adds the print settings from self
to key_file
.
key_file
the GKeyFile
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”
