You can use the exact - same code for the actual printing as for having the preview - generated, including calling QPrinter::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. - - \o Call exec(). - - Call QPrintPreviewDialog::exec() to show the preview dialog. - \endlist - - In Symbian, there is no support for printing.
