\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. |
|
374 |
||
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. |
|
401 |
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(). |
