public final class PrintOperation
extends GObject

Controls a print operation.

A WebKitPrintOperation controls a print operation in WebKit. With a similar API to GtkPrintOperation, it lets you set the print settings with webkit_print_operation_set_print_settings() or display the print dialog with webkit_print_operation_run_dialog().

Constructor Details

PrintOperation

public PrintOperation(MemorySegment address)

Create a PrintOperation proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

PrintOperation

public PrintOperation(WebView webView)
               throws UnsupportedPlatformException

Create a new WebKitPrintOperation to print webView contents.

Parameters:

webView - a WebKitWebView

Throws:

UnsupportedPlatformException - when run on a platform other than linux

Method Details

getType

public static Type getType()

Get the GType of the PrintOperation class

Returns:

the GType

asParent

protected PrintOperation asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class GObject

getPageSetup

public PageSetup getPageSetup()

Return the current page setup of this PrintOperation.

It returns null until either webkit_print_operation_set_page_setup() or webkit_print_operation_run_dialog() have been called.

Returns:

the current GtkPageSetup of this PrintOperation.

getPrintSettings

public PrintSettings getPrintSettings()

Return the current print settings of this PrintOperation.

It returns null until either webkit_print_operation_set_print_settings() or webkit_print_operation_run_dialog() have been called.

Returns:

the current GtkPrintSettings of this PrintOperation.

print

public void print()

Start a print operation using current print settings and page setup.

Start a print operation using current print settings and page setup without showing the print dialog. If either print settings or page setup are not set with webkit_print_operation_set_print_settings() and webkit_print_operation_set_page_setup(), the default options will be used and the print job will be sent to the default printer. The WebKitPrintOperation::finished signal is emitted when the printing operation finishes. If an error occurs while printing the signal WebKitPrintOperation::failed is emitted before WebKitPrintOperation::finished.

If the app is running in a sandbox, this function only works if printing to a file that is in a location accessible to the sandbox, usually acquired through the File Chooser portal. This function will not work for physical printers when running in a sandbox.

runDialog

public PrintOperationResponse runDialog(@Nullable
 @Nullable Window parent)

Run the print dialog and start printing.

Run the print dialog and start printing using the options selected by the user. This method returns when the print dialog is closed. If the print dialog is cancelled PrintOperationResponse.CANCEL is returned. If the user clicks on the print button, PrintOperationResponse.PRINT is returned and the print operation starts. In this case, the WebKitPrintOperation::finished signal is emitted when the operation finishes. If an error occurs while printing, the signal WebKitPrintOperation::failed is emitted before WebKitPrintOperation::finished. If the print dialog is not cancelled current print settings and page setup of this PrintOperation are updated with options selected by the user when Print button is pressed in print dialog. You can get the updated print settings and page setup by calling webkit_print_operation_get_print_settings() and webkit_print_operation_get_page_setup() after this method.

Parameters:

parent - transient parent of the print dialog

Returns:

the WebKitPrintOperationResponse of the print dialog

setPageSetup

public void setPageSetup(PageSetup pageSetup)

Set the current page setup of this PrintOperation.

Current page setup is used for the initial values of the print dialog when webkit_print_operation_run_dialog() is called.

Parameters:

pageSetup - a GtkPageSetup to set

setPrintSettings

public void setPrintSettings(PrintSettings printSettings)

Set the current print settings of this PrintOperation.

Set the current print settings of this PrintOperation. Current print settings are used for the initial values of the print dialog when webkit_print_operation_run_dialog() is called.

Parameters:

printSettings - a GtkPrintSettings to set

onFailed

public SignalConnection<PrintOperation.FailedCallback> onFailed(PrintOperation.FailedCallback handler)

Emitted when an error occurs while printing. The given error, of the domain WEBKIT_PRINT_ERROR, contains further details of the failure. The WebKitPrintOperation::finished signal is emitted after this one.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• PrintOperation.FailedCallback.run(org.gnome.glib.GError)

emitFailed

public void emitFailed(GError error)

Emits the "failed" signal. See onFailed(org.gnome.webkit.PrintOperation.FailedCallback).

onFinished

public SignalConnection<PrintOperation.FinishedCallback> onFinished(PrintOperation.FinishedCallback handler)

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

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• PrintOperation.FinishedCallback.run()

emitFinished

public void emitFinished()

Emits the "finished" signal. See onFinished(org.gnome.webkit.PrintOperation.FinishedCallback).

builder

public static PrintOperation.Builder<? extends PrintOperation.Builder> builder()

A PrintOperation.Builder object constructs a PrintOperation with the specified properties. Use the various set...() methods to set properties, and finish construction with PrintOperation.Builder.build().
