Detailed Description#

Using QPrintPreviewDialog in your existing application is straightforward:

Create the QPrintPreviewDialog .

You can construct a QPrintPreviewDialog with an existing QPrinter object, or you can have QPrintPreviewDialog create one for you, which will be the system default printer.

Connect the paintRequested() signal to a slot.

When the dialog needs to generate a set of preview pages, the paintRequested() signal will be emitted. You can use the exact same code for the actual printing as for having the preview generated, including calling newPage() to start a new page in the preview. Connect a slot to the paintRequested() signal, where you draw onto the QPrinter object that is passed into the slot.

Call exec().

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