Detailed DescriptionThe QPrintDialog class provides a dialog for specifying the printer's configuration. The dialog allows users to change document-related settings, such as the paper size and orientation, type of print (color or grayscale), range of pages, and number of copies to print. Controls are also provided to enable users to choose from the printers available, including any configured network printers. Typically, QPrintDialog objects are constructed with a QPrinter object, and executed using the exec() function. QPrintDialog printDialog(printer, parent); if (printDialog.exec() == QDialog::Accepted) { // print ... } If the dialog is accepted by the user, the QPrinter object is correctly configured for printing.
The printer dialog (shown above in Plastique style) enables access to common printing properties. On X11 platforms that use the CUPS printing system, the settings for each available printer can be modified via the dialog's Properties push button. On Windows and Mac OS X, the native print dialog is used, which means that 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, i.e. setOptions() and setOption() have no effect. In Qt 4.4, it was possible to use the static functions to show a sheet on Mac OS X. This is no longer supported in Qt 4.5. If you want this functionality, use QPrintDialog::open(). See also QPageSetupDialog, QPrinter, Pixelator Example, Order Form Example, Image Viewer Example, and Scribble Example. Property Documentation

Member Function Documentation
QPrintDialog::QPrintDialog(QPrinter * printer, QWidget * parent = 0)
Constructs a new modal printer dialog for the given printer with the given parent.
QPrintDialog::QPrintDialog(QWidget * parent = 0)
Constructs a print dialog with the given parent.
QPrintDialog::~QPrintDialog()
Destroys the print dialog.
void QPrintDialog::accepted(QPrinter * printer) [signal]
This signal is emitted when the user accepts the values set in the print dialog. The printer parameter includes the printer that the settings were applied to.
void QPrintDialog::done(int result) [virtual]
Reimplemented from QDialog::done().
Closes the dialog and sets its result code to result. If this dialog is shown with exec(), done() causes the local event loop to finish, and exec() to return result.
See also QDialog::done().
int QPrintDialog::exec() [virtual]
Reimplemented from QDialog::exec().
void QPrintDialog::open(QObject * receiver, const char * member)
This is an overloaded function.
Opens the dialog and connects its accepted() signal to the slot specified by receiver and member.
The signal will be disconnected from the slot when the dialog is closed.
This function was introduced in Qt 4.5.
QPrinter * QPrintDialog::printer()
Returns the printer that this printer dialog operates on. This can be useful when using the QPrintDialog::open() method.
void QPrintDialog::setOption(PrintDialogOption option, bool on = true)
Sets the given option to be enabled if on is true; otherwise, clears the given option.
See also options and testOption().
void QPrintDialog::setVisible(bool visible) [virtual]
Reimplemented from QWidget::setVisible().
bool QPrintDialog::testOption(PrintDialogOption option) const
Returns true if the given option is enabled; otherwise, returns false.
