Gtk::PrintContext Class Reference
[Printing]

Inheritance diagram for Gtk::PrintContext:

List of all members.


Detailed Description

A 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.

PrintContext objects gets passed to the begin-print, end-print, request-page-setup and draw-page signals on the PrintOperation.

Since gtkmm 2.10:

const GtkPrintContext* Gtk::PrintContext::gobj (  )  const [inline]

Provides access to the underlying C GObject.

Reimplemented from Glib::ObjectBase.

GtkPrintContext* Gtk::PrintContext::gobj (  )  [inline]

Provides access to the underlying C GObject.

Reimplemented from Glib::ObjectBase.

GtkPrintContext* Gtk::PrintContext::gobj_copy (  ) 

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

void Gtk::PrintContext::set_cairo_context ( const Cairo::RefPtr< Cairo::Context > &  cr,
double  dpi_x,
double  dpi_y 
)

Sets a new cairo context on a print context.

This function is intended to be used when implementing an internal print preview, it is not needed for printing, since GTK+ itself creates a suitable cairo context in that case.

Since gtkmm 2.10:
Parameters:
cr The cairo context.
dpi_x The horizontal resolution to use with cr.
dpi_y The vertical resolution to use with cr.
