PrintOperation

GtkPrintOperation is the high-level, portable printing API. It looks a bit different than other GTK+ dialogs such as the #GtkFileChooser, since some platforms don’t expose enough infrastructure to implement a good print dialog. On such platforms, GtkPrintOperation uses the native print dialog. On platforms which do not provide a native print dialog, GTK+ uses its own, see #GtkPrintUnixDialog.

The typical way to use the high-level printing API is to create a GtkPrintOperation object with gtk.print_operation.PrintOperation.new_ when the user selects to print. Then you set some properties on it, e.g. the page size, any #GtkPrintSettings from previous print operations, the number of pages, the current page, etc.

Then you start the print operation by calling gtk.print_operation.PrintOperation.run. It will then show a dialog, let the user select a printer and options. When the user finished the dialog various signals will be emitted on the #GtkPrintOperation, the main one being #GtkPrintOperation::draw-page, which you are supposed to catch and render the page on the provided #GtkPrintContext using Cairo.

The high-level printing API

static GtkPrintSettings *settings = NULL;

static void
do_print (void)
{
  GtkPrintOperation *print;
  GtkPrintOperationResult res;

  print = gtk_print_operation_new ();

  if (settings != NULL)
    gtk_print_operation_set_print_settings (print, settings);

  g_signal_connect (print, "begin_print", G_CALLBACK (begin_print), NULL);
  g_signal_connect (print, "draw_page", G_CALLBACK (draw_page), NULL);

  res = gtk_print_operation_run (print, GTK_PRINT_OPERATION_ACTION_PRINT_DIALOG,
                                 GTK_WINDOW (main_window), NULL);

  if (res == GTK_PRINT_OPERATION_RESULT_APPLY)
    {
      if (settings != NULL)
        g_object_unref (settings);
      settings = g_object_ref (gtk_print_operation_get_print_settings (print));
    }

  g_object_unref (print);
}

By default GtkPrintOperation uses an external application to do print preview. To implement a custom print preview, an application must connect to the preview signal. The functions gtk.print_operation_preview.PrintOperationPreview.renderPage, gtk.print_operation_preview.PrintOperationPreview.endPreview and gtk.print_operation_preview.PrintOperationPreview.isSelected

are useful when implementing a print preview.

Runs the print operation, by first letting the user modify print settings in the print dialog, and then print the document.

self
PrintOperation self()

Returns this, for use in with statements.

Sets whether selection is supported by #GtkPrintOperation.

setTrackPrintStatus
void setTrackPrintStatus(bool trackStatus)

If track_status is true, the print operation will try to continue report on the status of the print job in the printer queues and printer. This can allow your application to show things like “out of paper” issues, and when the print job actually reaches the printer.

setUnit
void setUnit(gtk.types.Unit unit)

Sets up the transformation for the cairo context obtained from #GtkPrintContext in such a way that distances are measured in units of unit.

bindProperty
gobject.binding.Binding bindProperty(string sourceProperty, gobject.object.ObjectWrap target, string targetProperty, gobject.types.BindingFlags flags)

Creates a binding between source_property on source and target_property on target.

bindPropertyFull
gobject.binding.Binding bindPropertyFull(string sourceProperty, gobject.object.ObjectWrap target, string targetProperty, gobject.types.BindingFlags flags, gobject.closure.Closure transformTo, gobject.closure.Closure transformFrom)

Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.

forceFloating
void forceFloating()

This function is intended for #GObject implementations to re-enforce a floating[floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling gobject.object.ObjectWrap.refSink.

freezeNotify
void freezeNotify()

Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.

getData
void* getData(string key)

Gets a named field from the objects table of associations (see gobject.object.ObjectWrap.setData).

getProperty
void getProperty(string propertyName, gobject.value.Value value)

Gets a property of an object.

getQdata
void* getQdata(glib.types.Quark quark)

This function gets back user data pointers stored via gobject.object.ObjectWrap.setQdata.

getv
void getv(string[] names, gobject.value.Value[] values)

Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.

isFloating
bool isFloating()

Checks whether object has a floating[floating-ref] reference.

notify
void notify(string propertyName)

Emits a "notify" signal for the property property_name on object.

notifyByPspec
void notifyByPspec(gobject.param_spec.ParamSpec pspec)

Emits a "notify" signal for the property specified by pspec on object.

refSink
gobject.object.ObjectWrap refSink()

Increase the reference count of object, and possibly remove the floating[floating-ref] reference, if object has a floating reference.

runDispose
void runDispose()

Releases all references to other objects. This can be used to break reference cycles.

setData
void setData(string key, void* data)

Each object carries around a table of associations from strings to pointers. This function lets you set an association.

setProperty
void setProperty(string propertyName, gobject.value.Value value)

Sets a property on an object.

stealData
void* stealData(string key)

Remove a specified datum from the object's data associations, without invoking the association's destroy handler.

stealQdata
void* stealQdata(glib.types.Quark quark)

This function gets back user data pointers stored via gobject.object.ObjectWrap.setQdata and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:

thawNotify
void thawNotify()

Reverts the effect of a previous call to gobject.object.ObjectWrap.freezeNotify. The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.

watchClosure
void watchClosure(gobject.closure.Closure closure)

This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling gobject.closure.Closure.invalidate on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, gobject.object.ObjectWrap.ref_ and gobject.object.ObjectWrap.unref are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.

connectNotify
gulong connectNotify(string detail, T callback, Flag!"After" after)

Connect to Notify signal.
