\class QPrintDialog

359 |
\brief The QPrintDialog class provides a dialog for specifying
|
|
360 |
the printer's configuration.
|
|
361 |
|
|
362 |
\ingroup standard-dialogs
|
|
363 |
\ingroup printing
|
|
364 |
|
|
365 |
The dialog allows users to change document-related settings, such
|
|
366 |
as the paper size and orientation, type of print (color or
|
|
367 |
grayscale), range of pages, and number of copies to print.
|
|
368 |
|
|
369 |
Controls are also provided to enable users to choose from the
|
|
370 |
printers available, including any configured network printers.
|
|
371 |
|
|
372 |
Typically, QPrintDialog objects are constructed with a QPrinter
|
|
373 |
object, and executed using the exec() function.

|
|
375 |
\snippet doc/src/snippets/code/src_gui_dialogs_qabstractprintdialog.cpp 0
|
|
376 |
|
|
377 |
If the dialog is accepted by the user, the QPrinter object is
|
|
378 |
correctly configured for printing.

The printer dialog (shown above in Plastique style) enables access to common
|
|
395 |
printing properties. On X11 platforms that use the CUPS printing system, the
|
|
396 |
settings for each available printer can be modified via the dialog's
|
|
397 |
\gui{Properties} push button.
|
|
398 |
|
|
399 |
On Windows and Mac OS X, the native print dialog is used, which means that
|
|
400 |
some QWidget and QDialog properties set on the dialog won't be respected.
|
|

The native print dialog on Mac OS X does not support setting printer options,
|
|
402 |
i.e. setOptions() and setOption() have no effect.
|
|
403 |
|
|
404 |
In Qt 4.4, it was possible to use the static functions to show a sheet on
|
|
405 |
Mac OS X. This is no longer supported in Qt 4.5. If you want this
|
|
406 |
functionality, use QPrintDialog::open().
