Struct PrintDialog

Source
pub struct PrintDialog { /* private fields */ }
Available on crate feature v4_14 only.
Expand description

A PrintDialog object collects the arguments that are needed to present a print dialog to the user, such as a title for the dialog and whether it should be modal.

The dialog is shown with the setup() function. The actual printing can be done with print() or print_file(). These APIs follows the GIO async pattern, and the results can be obtained by calling the corresponding finish methods.

§Properties

§accept-label

A label that may be shown on the accept button of a print dialog that is presented by PrintDialog::setup().

Readable | Writeable

Whether the print dialog is modal.

Readable | Writeable

§page-setup

The page setup to use.

Readable | Writeable

The print settings to use.

§title

A title that may be shown on the print dialog that is presented by PrintDialog::setup().

§Implements

[trait@glib::ObjectExt]

GLib type: GObject with reference counted clone semantics.

Implementations§

Source§

impl PrintDialog

Source

pub fn new() -> PrintDialog

Creates a new PrintDialog object.

§Returns

the new PrintDialog

Source

pub fn builder() -> PrintDialogBuilder

Creates a new builder-pattern struct instance to construct PrintDialog objects.

This method returns an instance of PrintDialogBuilder which can be used to create PrintDialog objects.

Source

pub fn accept_label(&self) -> GString

Returns the label that will be shown on the accept button of the print dialog.

§Returns

the accept label

Source

pub fn is_modal(&self) -> bool

Returns whether the print dialog blocks interaction with the parent window while it is presented.

§Returns

whether the print dialog is modal

Source

pub fn page_setup(&self) -> Option<PageSetup>

Returns the page setup.

§Returns

the page setup

Source

pub fn print_settings(&self) -> Option<PrintSettings>

Returns the print settings for the print dialog.

§Returns

the settings

Source

pub fn title(&self) -> GString

Returns the title that will be shown on the print dialog.

§Returns

the title

Source

pub fn print<P: FnOnce(Result<OutputStream, Error>) + 'static>( &self, parent: Option<&impl IsA<Window>>, setup: Option<&PrintSetup>, cancellable: Option<&impl IsA<Cancellable>>, callback: P, )

This function prints content from a stream.

If you pass NULL as @setup, then this method will present a print dialog. Otherwise, it will attempt to print directly, without user interaction.

The @callback will be called when the printing is done.

§parent

the parent Window

§setup

the PrintSetup to use

§cancellable

a GCancellable to cancel the operation

§callback

a callback to call when the operation is complete

Source

pub fn print_future( &self, parent: Option<&(impl IsA<Window> + Clone + 'static)>, setup: Option<&PrintSetup>, ) -> Pin<Box_<dyn Future<Output = Result<OutputStream, Error>> + 'static>>

Source

pub fn print_file<P: FnOnce(Result<(), Error>) + 'static>( &self, parent: Option<&impl IsA<Window>>, setup: Option<&PrintSetup>, file: &impl IsA<File>, cancellable: Option<&impl IsA<Cancellable>>, callback: P, )

This function prints a file.

If you pass NULL as @setup, then this method will present a print dialog. Otherwise, it will attempt to print directly, without user interaction.

§parent

the parent Window

§setup

the PrintSetup to use

§file

the GFile to print

§cancellable

a GCancellable to cancel the operation

§callback

a callback to call when the operation is complete

Source

pub fn print_file_future( &self, parent: Option<&(impl IsA<Window> + Clone + 'static)>, setup: Option<&PrintSetup>, file: &(impl IsA<File> + Clone + 'static), ) -> Pin<Box_<dyn Future<Output = Result<(), Error>> + 'static>>

Source

pub fn set_accept_label(&self, accept_label: &str)

Sets the label that will be shown on the accept button of the print dialog shown for setup().

§accept_label

the new accept label

Source

pub fn set_modal(&self, modal: bool)

Sets whether the print dialog blocks interaction with the parent window while it is presented.

the new value

Source

pub fn set_page_setup(&self, page_setup: &PageSetup)

Set the page setup for the print dialog.

§page_setup

the new page setup

Source

pub fn set_print_settings(&self, print_settings: &PrintSettings)

Sets the print settings for the print dialog.

the new print settings

Source

pub fn set_title(&self, title: &str)

Sets the title that will be shown on the print dialog.

§title

the new title

Source

pub fn setup<P: FnOnce(Result<PrintSetup, Error>) + 'static>( &self, parent: Option<&impl IsA<Window>>, cancellable: Option<&impl IsA<Cancellable>>, callback: P, )

This function presents a print dialog to let the user select a printer, and set up print settings and page setup.

The @callback will be called when the dialog is dismissed. The obtained PrintSetup can then be passed to print() or print_file().

One possible use for this method is to have the user select a printer, then show a page setup UI in the application (e.g. to arrange images on a page), then call print() on @self to do the printing without further user interaction.

§parent

the parent Window

§cancellable

a GCancellable to cancel the operation

§callback

a callback to call when the operation is complete
