OnPrint不会从CFormView调用 [英] OnPrint Does not get called from CFormView

问题描述

我正在研究MDI应用程序，其所有视图都是CFormView派生的。

在其中一个视图中显示需要打印的图表。

我覆盖了所有必要的功能，如OnBeginPrinting，OnPrint等。

但这些函数没有被调用。请帮助

I am working on MDI Application which has all views as CFormView Derived.
On one of view there is graph displayed which needs to be printed.
I overridden all necessary functions like OnBeginPrinting,OnPrint etc.
But these functions did not get called.Please Help

推荐答案

根据文档 [ ^ ]调用此函数来打印每个页面。您确定已正确初始化打印参数吗？

According to the documentation[^] this function gets called to print each page. Are you sure that you have initialised the print parameters correctly?

我在OnPreparePrinting函数中添加了行CView :: DoPreparePrinting，如其他一些网站所建议的那样工作

I added line CView::DoPreparePrinting in OnPreparePrinting Function as suggested in some other site and things worked
