QPrinter易于使用。您只需使用与QPainter交谈的方式绘制到页面上的方式相同 。 prnt = qt.QPrinter() #你还可以改变颜色,文档名称,dpi等选项 #显示对话框给用户(你实际上可以把它留出来) 如果是prnt.setup(): painter = qt.QPainter() painter.begin(打印机) #做的东西给吸引画家 painter.end(打印机) #每页之间这样做 printer.newPage() #...可以向画家打印更多页面 这很容易做到。如果你想处理多个页面等等, 有一些工作可以做到与对话框接口以获得 用户选择的页面范围,等等。 Jeremy - Jeremy Sanders http://www.jeremysanders.net/ Jeremy桑德斯写道:Jeremy Sanders wrote: Fabian Steiner写道: Fabian Steiner wrote:不幸的是我不知道如何实现这一点,因为还有一些图像和不同的盒子应打印出来。由于整个应用程序基于QT,可能会使用QPrinter,但我找不到任何示例如何使用它。 Unfortunately I don''t know how to realize this, since also some images and different boxes should be printed out.

[。 ..] 这很容易做到。如果你想处理多个页面等等,有一些工作要做,以便与对话框接口以获得用户选择的页面范围等。 [...] It''s very easy to do. If you want to handle multiple pages and so on, there''s a bit of work to do to interface to the dialog to get the user-selected page range, etc. 这就是QPrintDialog的用武之地: http://doc.trolltech.com/4.1/qprintdialog.html 它也在Qt 3中秘密提供通过QPrinter.setup()方法: printer = QPrinter() printer.setup() #现在,像往常一样在打印机上涂漆。 David That''s where QPrintDialog comes in: http://doc.trolltech.com/4.1/qprintdialog.html It''s also secretly available in Qt 3 via the QPrinter.setup() method: printer = QPrinter()printer.setup()# Now, paint onto the printer as usual. David 嗨! 到目前为止,谢谢你,但现在我再次陷入困境: - / Jeremy Sanders写道:Hi! Thank you so far, but now I got stuck again :-/Jeremy Sanders wrote: QPrinter易于使用。您只需使用QPainter以与屏幕对话的方式绘制页面。 prnt = qt.QPrinter()#您还可以改变颜色等选项,doc name,dpi here #显示对话框给用户(你实际上可以把它留出来)如果是prnt.setup(): painter = qt.QPainter() painter.begin(打印机)#画画给画家画画 painter.end(打印机)#每页之间做这个 printer.newPage() QPrinter is easy to use. You just draw to the page the same way as you talk to the screen with a QPainter. prnt = qt.QPrinter() # you can also vary options like colour, doc name, dpi here # display dialog box to user (you can actually leave this out) if prnt.setup(): painter = qt.QPainter() painter.begin(printer) # do stuff to draw to painter painter.end(printer) # do this between each page printer.newPage() 这是我到目前为止: app = QApplication(sys.argv) printer = QPrinter(QPrinter.PrinterResolution) 如果是printer.setup(): printer.setPageSize(printer.A4) painter = QPainter(打印机) ) metrics = QPaintDeviceMetrics(painter.device()) marginHeight = 6 marginWidth = 8 body = QRect(marginWidth,marginHeight,metrics.widthMM() - 2 * marginWidth,metrics.heightMM() - 2 * marginHeight) painter.drawRect(正文) painter.end() 这样做我希望得到一个矩形,与A4纸一样大( a小边框),但不幸的是它要小得多。此外,我问自己是否有必要为了在论文上写文字, 我总是要将正确的x,y值传递给QPainter.drawText ()。 还有其他可能吗?我如何获得这些价值? 提前致谢, Fabian Steiner This is what I have so far: app = QApplication(sys.argv)printer = QPrinter(QPrinter.PrinterResolution)if printer.setup():printer.setPageSize(printer.A4)painter = QPainter(printer)metrics = QPaintDeviceMetrics(painter.device())marginHeight = 6marginWidth = 8body = QRect(marginWidth, marginHeight, metrics.widthMM() - 2 *marginWidth, metrics.heightMM() - 2 * marginHeight)painter.drawRect(body)painter.end() Doing so I hoped to get a rectangle which is as big as an A4 paper (witha small border), but unfortunately it is much smaller. Moreover, I askmyself whether it is necessary that in order to write text on the paper,I always have to pass the proper x, y values to QPainter.drawText().Isn''t there any other possibility? How do I get these values?Thanks in advance,Fabian Steiner 这篇关于打印文件的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
