PrintFramework
This is an overview of the classes and methods used to print documents.
It also demonstrates how to do print previews and invoke the printer
setup dialog.
Classes demonstrated here:
- wx.Printout() - This class encapsulates the functionality of printing out
an application document. A new class must be derived and members overridden
to respond to calls such as OnPrintPage and HasPage. Instances of this class
are passed to wx.Printer.Print() or a wx.PrintPreview object to initiate
printing or previewing.
- wx.PrintData() - This class holds a variety of information related to
printers and printer device contexts. This class is used to create a
wx.PrinterDC and a wx.PostScriptDC. It is also used as a data member of
wx.PrintDialogData and wx.PageSetupDialogData, as part of the mechanism for
transferring data between the print dialogs and the application.
- wx.PrintDialog() - This class represents the print and print setup
common dialogs. You may obtain a wx.PrinterDC device context from a
successfully dismissed print dialog.
- wx.PrintPreview() - Objects of this class manage the print preview
process. The object is passed a wx.Printout object, and the wx.PrintPreview
object itself is passed to a wx.PreviewFrame object. Previewing is started by
initializing and showing the preview frame. Unlike wxPrinter.Print, flow of
control returns to the application immediately after the frame is shown.
Other classes are also demonstrated, but this is the gist of the printer interface
framework in wxPython.
