636 \class QPrintPreviewDialog -

637 \since 4.4 -

638 -

639 \brief The QPrintPreviewDialog class provides a dialog for -

640 previewing and configuring page layouts for printer output. -

641 -

642 \ingroup standard-dialogs -

643 \ingroup printing -

644 \inmodule QtPrintSupport -

645 -

646 Using QPrintPreviewDialog in your existing application is -

647 straightforward: -

648 -

649 \list 1 -

650 \li Create the QPrintPreviewDialog. -

651 -

652 You can construct a QPrintPreviewDialog with an existing QPrinter -

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

654 which will be the system default printer. -

655 -

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

657 -

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

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

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

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

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

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

664 into the slot. -

665 -

666 \li Call exec(). -

667 -

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

669 \endlist -
