protected procedure TPrinter.DoBeginDoc; virtual; |
DoBeginDoc is a virtual procedure which performs actions needed when printing is started for a document. DoBeginDoc is called from the BeginDoc method, and occurs after checking the printer status and updating values in PrinterFlags. When RawMode is False, the Canvas has already been refreshed and its BeginDoc method has been called.
Remark: | In TPrinter, DoBeginDoc has an empty implementation. It must be overridden in a descendent class to perform actions needed for the operating system / widgetset / printer-related technology used in the implementation. |
