QPrintPreviewDialog Class

Detailed Description

Using QPrintPreviewDialog in your existing application is straightforward:

1. 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.

2. 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 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.

3. Call exec().

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