Struct PaperSize 

pub struct PaperSize { /* private fields */ }

GtkPaperSize handles paper sizes. It uses the standard called PWG 5101.1-2002 PWG: Standard for Media Standardized Names to name the paper sizes (and to get the data for the page sizes). In addition to standard paper sizes, GtkPaperSize allows to construct custom paper sizes with arbitrary dimensions.

The PaperSize object stores not only the dimensions (width and height) of a paper size and its name, it also provides default [print margins][print-margins].

Printing support has been added in GTK+ 2.10.

Implementations

impl PaperSize

pub fn as_ptr(&self) -> *mut GtkPaperSize

Return the inner pointer to the underlying C value.

pub unsafe fn from_glib_ptr_borrow<'a>( ptr: *const *const GtkPaperSize, ) -> &'a Self
