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_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_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

|[<!-- language="C" --> 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_render_page(), gtk_print_operation_preview_end_preview() and gtk_print_operation_preview_is_selected() are useful when implementing a print preview.

Functions

addOnBeginPrint
gulong addOnBeginPrint(void delegate(PrintContext, PrintOperation) dlg, ConnectFlags connectFlags)

Emitted after the user has finished changing print settings in the dialog, before the actual rendering starts.

addOnCreateCustomWidget
gulong addOnCreateCustomWidget(ObjectG delegate(PrintOperation) dlg, ConnectFlags connectFlags)

Emitted when displaying the print dialog. If you return a widget in a handler for this signal it will be added to a custom tab in the print dialog. You typically return a container widget with multiple widgets in it.

addOnCustomWidgetApply
gulong addOnCustomWidgetApply(void delegate(Widget, PrintOperation) dlg, ConnectFlags connectFlags)

Emitted right before #GtkPrintOperation::begin-print if you added a custom widget in the #GtkPrintOperation::create-custom-widget handler. When you get this signal you should read the information from the custom widgets, as the widgets are not guaraneed to be around at a later time.

addOnDone
gulong addOnDone(void delegate(GtkPrintOperationResult, PrintOperation) dlg, ConnectFlags connectFlags)

Emitted when the print operation run has finished doing everything required for printing.

addOnDrawPage
gulong addOnDrawPage(void delegate(PrintContext, int, PrintOperation) dlg, ConnectFlags connectFlags)

Emitted for every page that is printed. The signal handler must render the @page_nr's page onto the cairo context obtained from @context using gtk_print_context_get_cairo_context(). |[<!-- language="C" --> static void draw_page (GtkPrintOperation *operation, GtkPrintContext *context, gint page_nr, gpointer user_data) { cairo_t *cr; PangoLayout *layout; gdouble width, text_height; gint layout_height; PangoFontDescription *desc;

addOnEndPrint
gulong addOnEndPrint(void delegate(PrintContext, PrintOperation) dlg, ConnectFlags connectFlags)

Emitted after all pages have been rendered. A handler for this signal can clean up any resources that have been allocated in the #GtkPrintOperation::begin-print handler.

addOnPaginate
gulong addOnPaginate(bool delegate(PrintContext, PrintOperation) dlg, ConnectFlags connectFlags)

Emitted after the #GtkPrintOperation::begin-print signal, but before the actual rendering starts. It keeps getting emitted until a connected signal handler returns %TRUE.

addOnPreview
gulong addOnPreview(bool delegate(PrintOperationPreviewIF, PrintContext, Window, PrintOperation) dlg, ConnectFlags connectFlags)

Gets emitted when a preview is requested from the native dialog.

addOnRequestPageSetup
gulong addOnRequestPageSetup(void delegate(PrintContext, int, PageSetup, PrintOperation) dlg, ConnectFlags connectFlags)

Emitted once for every page that is printed, to give the application a chance to modify the page setup. Any changes done to @setup will be in force only for printing this page.

addOnStatusChanged
gulong addOnStatusChanged(void delegate(PrintOperation) dlg, ConnectFlags connectFlags)

Emitted at between the various phases of the print operation. See #GtkPrintStatus for the phases that are being discriminated. Use gtk_print_operation_get_status() to find out the current status.

addOnUpdateCustomWidget
gulong addOnUpdateCustomWidget(void delegate(Widget, PageSetup, PrintSettings, PrintOperation) dlg, ConnectFlags connectFlags)

Emitted after change of selected printer. The actual page setup and print settings are passed to the custom widget, which can actualize itself according to this change.

cancel
void cancel()

Gets the value of #GtkPrintOperation:embed-page-setup property.

getError
void getError()

Call this when the result of a print operation is %GTK_PRINT_OPERATION_RESULT_ERROR, either as returned by gtk_print_operation_run(), or in the #GtkPrintOperation::done signal handler. The returned #GError will contain more details on what went wrong.

getHasSelection
bool getHasSelection()

getSupportSelection
bool getSupportSelection()

Gets the value of #GtkPrintOperation:support-selection property.

isFinished
bool isFinished()

run
GtkPrintOperationResult run(GtkPrintOperationAction action, Window parent)

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

setAllowAsync
void setAllowAsync(bool allowAsync)

Sets whether the gtk_print_operation_run() may return before the print operation is completed. Note that some platforms may not allow asynchronous operation.

setCurrentPage
void setCurrentPage(int currentPage)

Sets the current page.

setCustomTabLabel
void setCustomTabLabel(string label)

Sets the label for the tab holding custom widgets.

setDefaultPageSetup
void setDefaultPageSetup(PageSetup defaultPageSetup)

Makes @default_page_setup the default page setup for @op.

setDeferDrawing
void setDeferDrawing()

Sets up the #GtkPrintOperation to wait for calling of gtk_print_operation_draw_page_finish() from application. It can be used for drawing page in another thread.

setEmbedPageSetup
void setEmbedPageSetup(bool embed)

Embed page size combo box and orientation combo box into page setup page. Selected page setup is stored as default page setup in #GtkPrintOperation.

setExportFilename
void setExportFilename(string filename)

Sets up the #GtkPrintOperation to generate a file instead of showing the print dialog. The indended use of this function is for implementing “Export to PDF” actions. Currently, PDF is the only supported format.

setHasSelection
void setHasSelection(bool hasSelection)

Sets whether there is a selection to print.

setJobName
void setJobName(string jobName)

Sets the name of the print job. The name is used to identify the job (e.g. in monitoring applications like eggcups).

setNPages
void setNPages(int nPages)

Sets the number of pages in the document.

setPrintSettings
void setPrintSettings(PrintSettings printSettings)

Sets the print settings for @op. This is typically used to re-establish print settings from a previous print operation, see gtk_print_operation_run().

setShowProgress
void setShowProgress(bool showProgress)

If @show_progress is %TRUE, the print operation will show a progress dialog during the print operation.

setStruct
void setStruct(GObject* obj)
Undocumented in source. Be warned that the author may not have intended to support it.
setSupportSelection
void setSupportSelection(bool supportSelection)

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(GtkUnit unit)

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

setUseFullPage
void setUseFullPage(bool fullPage)

If @full_page is %TRUE, the transformation for the cairo context obtained from #GtkPrintContext puts the origin at the top left corner of the page (which may not be the top left corner of the sheet, depending on page orientation and the number of pages per sheet). Otherwise, the origin is at the top left corner of the imageable area (i.e. inside the margins).

getType
GType getType()
compatControl
size_t compatControl(size_t what, void* data)
interfaceFindProperty
ParamSpec interfaceFindProperty(TypeInterface gIface, string propertyName)

Find the #GParamSpec with the given name for an interface. Generally, the interface vtable passed in as @g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

interfaceInstallProperty
void interfaceInstallProperty(TypeInterface gIface, ParamSpec pspec)

Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.

interfaceListProperties
ParamSpec[] interfaceListProperties(TypeInterface gIface)

Lists the properties of an interface.Generally, the interface vtable passed in as @g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

addToggleRef
void addToggleRef(GToggleNotify notify, void* data)

Increases the reference count of the object by one and sets a callback to be called when all other references to the object are dropped, or when this is already the last reference to the object and another reference is established.

addWeakPointer
void addWeakPointer(void* weakPointerLocation)

Adds a weak reference from weak_pointer to @object to indicate that the pointer located at @weak_pointer_location is only valid during the lifetime of @object. When the @object is finalized, @weak_pointer will be set to %NULL.

bindProperty
Binding bindProperty(string sourceProperty, ObjectG target, string targetProperty, GBindingFlags flags)

Creates a binding between @source_property on @source and @target_property on @target. Whenever the @source_property is changed the @target_property is updated using the same value. For instance:

bindPropertyFull
Binding bindPropertyFull(string sourceProperty, ObjectG target, string targetProperty, GBindingFlags flags, GBindingTransformFunc transformTo, GBindingTransformFunc transformFrom, void* userData, GDestroyNotify notify)

Complete version of g_object_bind_property().

bindPropertyWithClosures
Binding bindPropertyWithClosures(string sourceProperty, ObjectG target, string targetProperty, GBindingFlags flags, Closure transformTo, 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.

dupData
void* dupData(string key, GDuplicateFunc dupFunc, void* userData)

This is a variant of g_object_get_data() which returns a 'duplicate' of the value. @dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.

dupQdata
void* dupQdata(GQuark quark, GDuplicateFunc dupFunc, void* userData)

This is a variant of g_object_get_qdata() which returns a 'duplicate' of the value. @dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.

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 g_object_ref_sink().

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 g_object_set_data()).

getProperty
void getProperty(string propertyName, Value value)

Gets a property of an object. @value must have been initialized to the expected type of the property (or a type to which the expected type can be transformed) using g_value_init().

getQdata
void* getQdata(GQuark quark)

This function gets back user data pointers stored via g_object_set_qdata().

getValist
void getValist(string firstPropertyName, void* varArgs)

Gets properties of an object.

getv
void getv(string[] names, 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(ParamSpec pspec)

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

doref
ObjectG doref()

Increases the reference count of @object.

refSink
ObjectG refSink()

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

removeToggleRef
void removeToggleRef(GToggleNotify notify, void* data)

Removes a reference added with g_object_add_toggle_ref(). The reference count of the object is decreased by one.

removeWeakPointer
void removeWeakPointer(void* weakPointerLocation)

Removes a weak reference from @object that was previously added using g_object_add_weak_pointer(). The @weak_pointer_location has to match the one used with g_object_add_weak_pointer().

replaceData
bool replaceData(string key, void* oldval, void* newval, GDestroyNotify destroy, GDestroyNotify* oldDestroy)

Compares the user data for the key @key on @object with @oldval, and if they are the same, replaces @oldval with @newval.

replaceQdata
bool replaceQdata(GQuark quark, void* oldval, void* newval, GDestroyNotify destroy, GDestroyNotify* oldDestroy)

Compares the user data for the key @quark on @object with @oldval, and if they are the same, replaces @oldval with @newval.

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.

setDataFull
void setDataFull(string key, void* data, GDestroyNotify destroy)

Like g_object_set_data() except it adds notification for when the association is destroyed, either by setting it to a different value or when the object is destroyed.

setProperty
void setProperty(string propertyName, Value value)

Sets a property on an object.

setQdata
void setQdata(GQuark quark, void* data)

This sets an opaque, named pointer on an object. The name is specified through a #GQuark (retrived e.g. via g_quark_from_static_string()), and the pointer can be gotten back from the @object with g_object_get_qdata() until the @object is finalized. Setting a previously set user data pointer, overrides (frees) the old pointer set, using #NULL as pointer essentially removes the data stored.

setQdataFull
void setQdataFull(GQuark quark, void* data, GDestroyNotify destroy)

This function works like g_object_set_qdata(), but in addition, a void (*destroy) (gpointer) function may be specified which is called with @data as argument when the @object is finalized, or the data is being overwritten by a call to g_object_set_qdata() with the same @quark.

setValist
void setValist(string firstPropertyName, void* varArgs)

Sets properties on an object.

setv
void setv(string[] names, Value[] values)

Sets @n_properties properties for an @object. Properties to be set will be taken from @values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.

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(GQuark quark)

This function gets back user data pointers stored via g_object_set_qdata() 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: |[<!-- language="C" --> void object_add_to_user_list (GObject *object, const gchar *new_string) { // the quark, naming the object data GQuark quark_string_list = g_quark_from_static_string ("my-string-list"); // retrive the old string list GList *list = g_object_steal_qdata (object, quark_string_list);

thawNotify
void thawNotify()

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

unref
void unref()

Decreases the reference count of @object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).

watchClosure
void watchClosure(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 g_closure_invalidate() on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, g_object_ref() and g_object_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.

weakRef
void weakRef(GWeakNotify notify, void* data)

Adds a weak reference callback to an object. Weak references are used for notification when an object is finalized. They are called "weak references" because they allow you to safely hold a pointer to an object without calling g_object_ref() (g_object_ref() adds a strong reference, that is, forces the object to stay alive).

weakUnref
void weakUnref(GWeakNotify notify, void* data)

Removes a weak reference callback to an object.

clearObject
void clearObject(ObjectG objectPtr)

Clears a reference to a #GObject.
