Example 11 with HeadlessException

use of java.awt.HeadlessException in project jdk8u_jdk by JetBrains.

the class ServiceUI method printDialog.

/**
     * Presents a dialog to the user for selecting a print service (printer).
     * It is displayed at the location specified by the application and
     * is modal.
     * If the specification is invalid or would make the dialog not visible it
     * will be displayed at a location determined by the implementation.
     * The dialog blocks its calling thread and is application modal.
     * <p>
     * The dialog may include a tab panel with custom UI lazily obtained from
     * the PrintService's ServiceUIFactory when the PrintService is browsed.
     * The dialog will attempt to locate a MAIN_UIROLE first as a JComponent,
     * then as a Panel. If there is no ServiceUIFactory or no matching role
     * the custom tab will be empty or not visible.
     * <p>
     * The dialog returns the print service selected by the user if the user
     * OK's the dialog and null if the user cancels the dialog.
     * <p>
     * An application must pass in an array of print services to browse.
     * The array must be non-null and non-empty.
     * Typically an application will pass in only PrintServices capable
     * of printing a particular document flavor.
     * <p>
     * An application may pass in a PrintService to be initially displayed.
     * A non-null parameter must be included in the array of browsable
     * services.
     * If this parameter is null a service is chosen by the implementation.
     * <p>
     * An application may optionally pass in the flavor to be printed.
     * If this is non-null choices presented to the user can be better
     * validated against those supported by the services.
     * An application must pass in a PrintRequestAttributeSet for returning
     * user choices.
     * On calling the PrintRequestAttributeSet may be empty, or may contain
     * application-specified values.
     * <p>
     * These are used to set the initial settings for the initially
     * displayed print service. Values which are not supported by the print
     * service are ignored. As the user browses print services, attributes
     * and values are copied to the new display. If a user browses a
     * print service which does not support a particular attribute-value, the
     * default for that service is used as the new value to be copied.
     * <p>
     * If the user cancels the dialog, the returned attributes will not reflect
     * any changes made by the user.
     *
     * A typical basic usage of this method may be :
     * <pre>{@code
     * PrintService[] services = PrintServiceLookup.lookupPrintServices(
     *                            DocFlavor.INPUT_STREAM.JPEG, null);
     * PrintRequestAttributeSet attributes = new HashPrintRequestAttributeSet();
     * if (services.length > 0) {
     *    PrintService service =  ServiceUI.printDialog(null, 50, 50,
     *                                               services, services[0],
     *                                               null,
     *                                               attributes);
     *    if (service != null) {
     *     ... print ...
     *    }
     * }
     * }</pre>
