详细描述

The QPrintPreviewDialog class provides a dialog for previewing and configuring page layouts for printer output.

Using QPrintPreviewDialog in your existing application is straightforward:

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.
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 () 到 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 槽。
调用 exec_ ().
调用 QPrintPreviewDialog.exec () to show the preview dialog.

In Symbian, there is no support for printing. Hence, this dialog should not be used in Symbian.

方法文档编制

QPrintPreviewDialog.init ( self , QWidget parent = None, Qt.WindowFlags flags = 0)

parent argument, if not None, causes self to be owned by Qt instead of PyQt.

构造 QPrintPreviewDialog 基于 printer 和采用 parent as the parent widget. The widget flags flags are passed on to the QWidget 构造函数。

另请参阅 QWidget.setWindowFlags ().

QPrintPreviewDialog.init ( self , QPrinter printer , QWidget parent = None, Qt.WindowFlags flags = 0)

parent argument, if not None, causes self to be owned by Qt instead of PyQt.

这是重载函数。

This will create an internal QPrinter object, which will use the system default printer.

QPrintPreviewDialog.done ( self , int result )

重实现自 QDialog.done ().

QPrintPreviewDialog.open ( self )

这是重载函数。

Opens the dialog and connects its finished(int) signal to the slot specified by receiver and member .

The signal will be disconnected from the slot when the dialog is closed.

该函数在 Qt 4.5 引入。

QPrintPreviewDialog.open ( self , QObject receiver , SLOT()SLOT() member )

QPrintPreviewDialog.open ( self , callable receiver )

QPrinter QPrintPreviewDialog.printer ( self )

返回指针指向 QPrinter object this dialog is currently operating on.

QPrintPreviewDialog.setVisible ( self , bool visible )

重实现自 QWidget.setVisible ().

Qt Signal Documentation

void paintRequested (QPrinter*)

This is the default overload of this signal.

此信号被发射当 QPrintPreviewDialog needs to generate a set of preview pages.

printer instance supplied is the paint device onto which you should paint the contents of each page, using the QPrinter instance in the same way as you would when printing directly.
