Description:

A Gtk.PrintContext encapsulates context information that is required when drawing pages for printing, such as the cairo context and important parameters like page size and resolution. It also lets you easily create Pango.Layout and Pango.Context objects that match the font metrics of the cairo surface.

Gtk.PrintContext objects gets passed to the Gtk.PrintOperation::begin-print.

Printing support was added in GTK+ 2.10.


Function Details:

get_cairo_context()

get_cairo_context (self) -> cairo.Context

Obtains the cairo context that is associated with theGtk.PrintContext.

  • Returns: the cairo context of context.

  • Since: 2.10


set_cairo_context()

set_cairo_context (self, cr:cairo.Context, dpi_x:float, dpi_y:float)

Sets a new cairo context on a print context. This function is intended to be used when implementingan internal print preview, it is not needed for printing,since GTK+ itself creates a suitable cairo context in thatcase.

  • Since: 2.10

get_page_setup()

get_page_setup (self) -> Gtk.PageSetup

Obtains the Gtk.PageSetup that determines the pagedimensions of the Gtk.PrintContext.

get_dpi_x (self) -> float

Obtains the horizontal resolution of the Gtk.PrintContext,in dots per inch.

  • Returns: the horizontal resolution of context

  • Since: 2.10


get_dpi_y()

get_dpi_y (self) -> float

Obtains the vertical resolution of the Gtk.PrintContext,in dots per inch.

  • Returns: the vertical resolution of context
