630 \class QPrintPreviewDialog -

631 \since 4.4 -

632 -

633 \brief The QPrintPreviewDialog class provides a dialog for -

634 previewing and configuring page layouts for printer output. -

635 -

636 \ingroup standard-dialogs -

637 \ingroup printing -

638 \inmodule QtPrintSupport -

639 -

640 Using QPrintPreviewDialog in your existing application is -

641 straightforward: -

642 -

643 \list 1 -

644 \li Create the QPrintPreviewDialog. -

645 -

646 You can construct a QPrintPreviewDialog with an existing QPrinter -

647 object, or you can have QPrintPreviewDialog create one for you, -

648 which will be the system default printer. -

649 -

650 \li Connect the paintRequested() signal to a slot. -

651 -

652 When the dialog needs to generate a set of preview pages, the -

653 paintRequested() signal will be emitted. You can use the exact -

654 same code for the actual printing as for having the preview -

655 generated, including calling QPrinter::newPage() to start a new -

656 page in the preview. Connect a slot to the paintRequested() -

657 signal, where you draw onto the QPrinter object that is passed -

658 into the slot. -

659 -

660 \li Call exec(). -

661 -

662 Call QPrintPreviewDialog::exec() to show the preview dialog. -

663 \endlist -
